Cabriolet

Cabriolet (pronounced kab-ree-uh-ley)

(1) A light, two-wheeled, one-horse carriage with a folding top, capable of seating two persons.  It's from cabriolet the term "cab" (in the sense of taxi) was derived).

(2) An automobile based usually on a two-door coupé but with a folding top.

(3) The equivalent continental term for the (mostly UK) drophead coupé (DHC) or the more generic "convertible".

1766: From the French cabriolet, the construct being the Italian cabriole (horse caper) + -et (the suffix here used in the sense of “smaller version”).  The Italian cabriole was from the Latin capreolus (wild goat), from the primitive Indo-European kápros (buck, he-goat) and related to the Old Norse hafr (he-goat), the Old English hæfr, the Welsh gafr and the Old Irish gabor.  The seemingly strange relationship between the Latin capreolus (roebuck; wild goat) and the eighteenth century horse-drawn carriage is explained by the French cabriole (little caper), the meaning derived from its light movement, from cabrioler (to leap, caper), from the Italian capriolare (to somersault), from the Latin capreolus (roebuck; wild goat), the idea being of something light and agile in movement.  The larger, more upscale version of the lightweight carriages the French named cabriolet, “cab” being the common form in the vernacular, picked up in English and used to this day, "cabbies" being "cab (taxi) drivers".  The –et suffix, indicating diminution or affection, was from Old French -et, and its feminine variant -ette, both derived from the Late Latin -ittus (and the other gender forms -itta, -ittum).  In English use, “cab” was picked up to describe the small carriages for hire in urban use and it was the descendants of these which became “taxicabs” when the French taximètres (automatic meter that records distance and fare) were adopted in the late 1890s, the word from the German Taxameter, from Taxanom, the construct based on Taxe (tax, charge or scale of charges), from the Medieval Latin taxa (tax, charge) + mètre.  Cabriolet is a noun, the noun plural is cabriolets.

1978 Cadillac Eldorado Cabriolet Astroroof.  The "Cabriolet Astroroof" (Option code CF5) added US$1565.00 over the Eldorado's base price of US$12401.00.  "Astroroof" was Cadillac's marketing term for a sunroof with a large, heavily tinted glass sliding panel.

The application of cabriolet to describe convertible cars emerged in the early years of the continental motor industry because of the conceptual similarity to the earlier, light, horse-drawn two-seater carriages but as the years went by, rapidly the industry retreated from the "terminological exactitude" stuck to by the coach-builders of the horse & buggy era.  The "carried over" nomenclature (cabriolet, landau, brougham etc) eventually became mere "model names" and what some styled a "cabriolet", others might call something else although usually "cabriolet" did imply some part of the roof could in some way be removed.  By 1977, GM (General Motors had decided that was a tiresome restriction and offered the "Cadillac Coupe DeVille Cabriolet d’Elegance" the rationale for the "cabriolet" element being the roof looked like it might be able to be lowered.  The structure was however fixed but the model sold well so for more than a decades Cadillac "cabriolets" appeared with solidly attached roofs.  Anyone looking up "cabriolet" in a dictionary may have been baffled but Cadillac owners knew what they wanted.

1979 Cadillac DeVille Custom Phaeton Coupe.  Those looking up "phaeton" may also have been mystified.

The 1977 venture may also have encouraged long model names because that trend persisted into the next century.  So what was used to describe the variations in convertible coachwork became something of the manufacturer's whim (except for the much later targa; Porsche had the foresight to register that as a trademark) and if a car was called a roadster, drophead coupé, phaeton, cabriolet or landau, it was an indication only that the roof could (usually) be removed or folded back.  In Detroit, the industry cheerfully used the historic names just as ways to impart "a certain association with something" and produced both "cabriolets" & "landaus" with fixed roofs and that trickery wasn't confined to the US, it being common practice in pre-war Europe for coupés to appear with non-functional "landau irons"; these were early "faux cabriolets".  One exception to that looseness was Daimler-Benz, the Germans tightly defining the specifications of roadsters and landaulets and, with Teutonic thoroughness, in the mid-twentieth century codified the five variations of Mercedes-Benz cabriolets as Cabriolet A, B, C, D & F (if ever there was a Cabriolet E, the factory’s definition has never surfaced).  With the fixed-roof two door bodies, "Coupé A" and "Coupé B" followed the same model (relating to seating & side windows).

Being a German company, Porsche from its early years used "cabriolet" to describe its soft-top models although the Americans never really embraced the idea, habitually calling the open 356s "convertibles".  Strangely, Volkswagen owners in the US took to the term, "cabriolet" usually preferred for the Karmann-built soft-top Beetles, the cabriolet in 1979 the last of the classic (Type 1, 1938-2003) Beetles sold in the US.  After the targa (a word diligently trade-marked although Triumph in the UK had offered something similar (though more complex) with the "Surrey Top", available on the TR4 (1961-1967) & TR5 (1967-1968 (TR250 in the US market)) models were introduced, there was anyway a reason for Porsche to avoid "convertible" as being "imprecise"; at that point, in the Porsche ecosystem, there were "coupés" & "Targas".  The 1970s were, as a general principle not "convertible-friendly" but as that troubled decade ended, it became obvious the regulatory environment was not going to become as restrictive as had been feared and at the 1981 Frankfurt Motor Show, Porsche showed an AWD (all-wheel-drive) 911 cabriolet concept that was so well-received a 911 Cabriolet the next year was added to the line, the company's first "full convertible" since the last of the 356s (1948-1965).  Just to clarify things, the press were informed there were no "convertibles" in the range, just "coupés", "Targas" and "cabriolets".  Such had been the enthusiasm generated by the 1981 concept-car it was obvious it would enter series-production but, upon release, the company confirmed it would not include the AWD and nor would the body-style be available with a turbocharged engine.  The rationale for that was the rather patronizing" "People who drive cabriolets neither need nor want AWD and 300 HP (horsepower) engines".  Amusingly, in an example of the way that in commerce "the customer is always right", where, regardless of "need", where there's "want" (ie demand), supply tends to follow and both features eventually were made available with the cabriolet body.

Saint John Paul II (1920–2005; pope 1978-2005) in  Ferrari Mondial cabriolet while on a visit to the Ferrari test track, Fiorano, Italy, 4 June 1988.  This is believed to be the fastest ever Popemobile.

The term "cabriolet" has over the decades been applied to convertible Ferraris but a convention seems to have emerged that exclusively it's now used for four seaters (that the factory admits are really 2+2s).  The factory has had 2+2 cabriolets in the line-up for a while, most recently the California (2008-2017), Portofino (2017-2023), Roma (2020-2026) and Amalfi (since 2026) but those used a conventional front-engine layout.  The Mondial (1980-1993) was mid-engined, making the accommodation of four within the cabin quite challenging and critics noted one of the compromises imposed was aesthetic, the body lacking Ferrari's usually lovely, lithe lines, something said also of its 2+2 predecessor, the fixed-roof 208 & 308 GT4 (sold as both a Dino and a Ferrari).  However, the practicality of the Mondial had great appeal and it was at the time one of the the most successful Ferraris ever made.  It was also something of a turning point, much thought having been put into the design, not only to ensure one basic specification could be sold in all markets but also that the cost of ownership would be lower by simplifying the servicing routines.  It was much improved as the years went by and made in four distinct generations but Ferrari have not since attempted another mid-engined 2+2 (the configuration of the Roma & Amalfi sometimes described as "front mid-engine" but such things are not listed with the classic "mid-engined" machines, all of which have the power-plant mounted behind the driver).

The classification of cabriolets by Daimler-Benz

Cabriolet A coachwork: 1937 Mercedes-Benz 540K (left), 1958 Mercedes-Benz 300 SC (centre) & 2017 Mercedes Maybach 6 (right).

A cabriolet with two doors, no rear-quarter window and room for two passengers.  Occasionally, cabriolet As would be built with provision for one additional passenger, seated sideways behind the front seats, an arrangement the factory would late use in the "Pagoda" roadsters (W113, 1963-1971) until outlawed by increasingly stringent US safety regulations.  With Mercedes-Benz, the tradition of the cabriolet A in the big, open two-seat convertible would survive only until the 300 S & 300 SC (W188, 1951-1958) although in 2017, the one-off Mercedes-Maybach 6 Cabriolet was displayed, probably the most extravagantly self-indulgent "big" two-seater seen since the inter-war (1919-1939) years.  That was mitigated somewhat by the electric power-train but series production was never considered.

Cabriolet B coachwork: 1970 Mercedes-Benz 280 SE 3.5 (left), 1993 Mercedes-Benz 300 CE (centre) & 2017 Mercedes-AMG S 650 (right).  As the S 650 illustrates, while the use of CAD (computer aided design) and wind tunnels can make shapes more aerodynamically efficient, they doesn't guarantee they'll emerge as more elegant.   

A cabriolet with two doors and room for four or five passengers, fitted with a rear-quarter window for the rear seat.  Other than when interrupted by World War II (1939-1945) and its aftermath, the cabriolet B was long a staple of the Mercedes-Benz line-up but between 1972-1992 there was a hiatus, fears that impending US legislation would outlaw convertible sales in that lucrative market meaning no two door variations were constructed on the new S-Class (W116, 1972-1980) platform and no convertible versions of the successor S-Class coupé (C126, 1981-1990) or the smaller (what would now be called "E-Class") coupé (C123, 1976-1984) were ever offered (although some third party suppliers did offer conversions, Crayford in the UK even sourcing the soft-tops for their C123 cabriolets from 1973 Ford Mustangs in US wrecking yards!).  In those years, the R107 (1971-1989) roadster was the sole convertible available, its sales outside the US sufficient to maintain profitability if the ban eventuated.  As things turned out, the ban never was imposed and the cabriolet B returned in the form of the E-Class A124 (1991-1997).  The "smaller" Cabriolet Bs have since remained available although restricted after 2023 to the even smaller C-Class (A236) and the brief return of a "big" Cabriolet B (the A217 S-Class, 2015-2020) seems an experiment unlikely soon to be repeated.

The feared ban on convertibles in the US is an amusing tale of interest to political scientists and economists.  FMVSS (federal motor vehicle safety standards) 208 (roll-over protection) was published in 1970 and one obvious implication was the banning of “real” convertibles in the US market; while the local manufacturers went to court to challenge some of the provisions in FMVSS 208, they made no attempt to prevent the demise of the convertible, sales of the configuration having fallen to the point the body-style was no longer offered in most lines and even without the intervention of government it’s likely availability would anyway further have been restricted to the odd specialist product.  Indeed, Chevrolet, aware of the coming edict, had in 1968 released the coupe version of the third generation (C3) Corvette as a kind of targa (the so-called “T-top” with removable roof panels), the remaining structure essentially a “roll-bar able to “drive through” FMVSS 208.

Compliant and not with FMVSS 208 as drafted: 1978 Chevrolet Corvette Coupe with T-Top roof (left) and 1978 Chrysler New Yorker, the last of the four-door hardtops (right).

As things turned out, there was a a lobbying effort by the AIA (Automobile Importers of America, a multi-national aggregation representing manufacturers from Europe, the UK and Japan making good profits from convertibles; indeed, some (notably MG) wholly were dependent on convertibles in the US market) to to gain exemptions because for many, even apart from the US-derived profits, it was the volumes achieved there that made viable continuation of the lines in other markets.  In an example of the way government and industry in the US interact (mostly through the mechanism of “campaign financing” with lobbyists as intermediaries), in 1971 the NHTSA (National Highway Traffic Safety Administration) granted a “temporary exemption” for convertibles from the rollover parameters, the "subset clause" set originally to expire on 31 August, 1977 (ie, the end of the 1977 model season), a date chosen because by then Detroit’s existing convertible lines were schedule to have reached their EoL (end of life).  The FMVSS 208 standards were otherwise maintained and that was what doomed to four-door hardtops which, lacking a central (B) pillar would have been prohibitively expensive to engineer into compliance.  However, late in 1972, an unexpected ruling from a federal court held FMVSS 208 existed under the provisions of the NTMVSA (National Traffic & Motor Vehicle Safety Act (1966)) and this was found to contain no statutory basis that could extend to the banning of convertibles: As explicitly the judgment stated, the act obligated the agency “to afford such vehicles special consideration.”  Detroit no more expected that than did the NHTSA but while the manufacturers were sanguine about no longer producing convertibles, the regulators were compelled to decide what to do about their regulation and, given Detroit’s attitude, they decided to "kick the can down the road" and simply extend the “temporary” exemption, nominating no end-date.  As does happen in politics, the "temporary" became "indefinite".

By the time the neo-liberal order began to take control in Washington after the election of Ronald Reagan (1911-2004; POTUS 1981-1989), the political zeitgeist shifted to a desire for "less" regulation and the exemption became "permanent", convertibles in the 1980s staging a comeback in the catalogues.  The indefinite extension of the "temporary exemption" of convertibles from FMVSS's roll-over standards created the curious anomaly that Chrysler could in theory have maintained a New Yorker convertible (had one existed) in production while being compelled to drop the four-door hardtop.  Market realities meant no Federal Court judge ever had to sit to resolve that and no manufacturer sought an exemption for the latter.  The last of the C3 (1968-1983) Corvette roadsters was produced in 1975, the style not revived in the line until a C4 (1984-1996) roadster was released in 1986.  Most relieved were the UK and European producers, their little roadsters highly profitable and perennially strong sellers in North America and while the AIA didn't get everything they asked for, they got convertibles and that allowed the life of many roadsters (some with roots in the 1950s) to be extended even into the mid-1990s by which time, in a sense, customers were buying "new vintage cars".        

1980 Mercedes-Benz 500 SLC.

The SLC (C107, 1971-1980) existed only because it was assumed convertible sales in the US would be banned so, with no S-Class, the "big coupé" role was fulfilled by the SLC, concocted by using a LWB (long wheelbase) version of the R107 roadster's platform with a rear seat and (non-pagoda) fixed roof.  Always expensive, the SLC sold well but it had also a career never envisaged when the product-planners were drawing-up the specifications; it was used as a rally car.  The big 450 SLC 5.0 (1977-1980) was one of the more improbable rally cars but it enjoyed success in long-distance events, in winning the Bandama Rally in Côte d'Ivoire an it's a footnote in the sport's history as the only V8-powered car to win a European rally; all 450 SLC 5.0s fitted with an automatic transmission which makes the thing more unusual still.        

Cabriolet C coachwork: 1937 Mercedes-Benz 540K (left), 1950 Jaguar Mark V Drophead Coupé (DHC) (centre) & 2020 Alvis TB60 DHC (continuation) (right).

A cabriolet with two doors and room for four or five passengers with no rear quarter windowMost German manufacturers and virtually all coachbuilders kept the cabriolet C on the books throughout the inter-war period but in the post-war years, it was the British who did most to maintain the tradition, Bentley, Rolls-Royce, Daimler, Armstrong Siddeley and Alvis all offering the style and Alvis in 2018 actually re-commenced production of what they called their "continuation" series.  Unlike their latter day use by US manufacturers, the often fitted external "landau irons" genuinely were functional in the raising and lowering of the soft-top.  Thankfully, those "faux landau irons" no longer attract US designers but the motif endures in those building hearses with large expanses of sheet mental rather than glass, the devices to some extent disguising and "breaking up" what would otherwise be just "too much flat surface".  By contrast, on a cabriolet C, the expanse of fabric can lend elegance but one obvious drawback is the restricted visibility, the bulk creating blind-spots rearward, something to bring a wry smile to drivers of 1971 "Sportsroof" Ford Mustangs.

Cabriolet D coachwork: 1961 Mercedes-Benz 300d (left), 1967 Lincoln Continental (centre) & 2006 Mercedes-Benz Concept Ocean Drive (right). 

A cabriolet with four doors and room for four to six passengers.  Common in the 1930s, the four door convertible was rare by the mid 1950s and even Mercedes-Benz removed the 300c (W186, 1951-1957) Cabriolet D from the range when the 300d (W189, 1957-1962) was released in 1958.  However, although demand for such a machine was tiny, it wasn't non-existent and in 1959 it was announced the Cabriolet D would again be available to special order on the basis of POA (price on application), the cost depending on the specification requested; eventually, a further 65 were built.  That was the last of the line however and when "semi-convertible" coachwork was introduced for the 600 (der Grosser; W100, 1963-1981), the term "landaulet" was preferred and these came in two forms: (1) the so-called "short roof" in which the folding mechanism opened only over the rear-most section and (2) the (unofficially dubbed) "presidential", the fabric extending to the central partition (divider).  Other than a one-off on the SWB (short wheelbase) platform, there were 59 600 Landaulets, 12 of them the "presidential" version, two of which remain in the care of Kim Jong-Un (Kim III, b 1982; Supreme Leader of DPRK (Democratic People's Republic of Korea (North Korea)) since 2011) who inherited (along with the rest of the DPRK and its people) from his equally illustrious ancestors.  Apart from the mouth-watering Concept Ocean Drive displayed in 2006, the factory has never hinted such things might return and, apart from truck-like off-road machines, nor has any other manufacturer since the last convertible Lincoln Continental left the line in 1967.  Remembered also for its connection to the limousine in which President John Kennedy (JFK, 1917–1963; POTUS 1961-1963) was assassinated, that association didn't dissuade his successor (Lyndon Johnson (LBJ, 1908–1973; VPOTUS 1961-1963 and POTUS 1963-1969) from owning one but even LBJ's presidential imprimatur didn't sufficiently stimulate sales and the four-door convertible coachwork didn't appear for 1968.  They were the last convertibles ever built by Lincoln.

Cabriolet F Coachwork: 1939 Mercedes-Benz 770K (W150) (left), 1961 Lincoln Continental (X-100 by Hess & Eisenhardt) (centre) & 1966 Mercedes-Benz 600 Landaulet in four-door, short roof configuration (right, which is not really a cabriolet F). 

A cabriolet with four doors, built on an extended wheelbase, usually for state or formal use with room for six or more passengers.  The rare cabriolet Fs were almost exclusively state or parade vehicles (although as used cars, they've been sometimes imaginatively re-purposed in the secondary market) and are now effectively extinct, driven from the market by security concerns and the lack of appropriate new vehicles upon which they could be based.  Politicians now feel much safer in armored cars, built sometimes on a light-truck chassis and the ones used by US presidents are now essentially "armored cars disguised as traditional (ie 1980s) Cadillac limousines.

1966 Mercedes-Benz 300 SE (W112) Cabriolet.  Lots of chrome on the W112 although, such was the attention to detail, some of the brightwork was polished brass. 

In the collector-car market, the two-door Mercedes-Benz W111 (1961-1971) & W112 (1962-1967) remain coveted and, as is usually the case, it's the convertibles that are most sought, even though the cabriolet lacks the coupé's lovely roofline.  Pedants note that although the W111s & W112s are technically a Coupé B & Cabriolet B in the factory's naming system, they're never referred to as such because no other configuration was offered in the two-door iterations.  The W112 (300 SE) is of interest too because of the moldings around the wheel arches, a feature which seen on some earlier models and the 600 Grosser.  Criticized by some when they appeared on the 600, the additional brightness on the W112 wasn't to everyone's taste (and it was a "delete option" when new) but it clearly had an enduring appeal because for decades, after-market suppliers found a ready market among those with later model Mercedes-Benz, BMWs, Jaguars and some others.  This is not approved by the purists and whether in chrome, stainless steel or anodised plastic (!) it makes no difference: the originality police insist if it wasn't done by the factory, it shouldn't be done.  It was a W112 Coupé (that had failed quality control inspection and was due to be scrapped!) that provided the test bed for the installation of the 600's 6.3 litre (386 cubic inch) V8 in a smaller platform and such was the transformative effect the project was approved for series-production although Daimler-Benz management was not convinced there would be sufficient demand for the "hot-rod" as a coupé or cabriolet and insisted it be released exclusively in four-door form.

Thus was begat the 300 SEL 6.3 (1968-1972) using the W109 platform (1965-1972) and it was for years was a favorite high-speed cruiser on the FRG's (Bundesrepublik Deutschland (Federal Republic of Germany; the old West Germany, 1949-1990) autobahns, drivers then even more than now not troubled by tiresome speed-limits.  It was a great success but there have been some who longed to combine the big V8 with the lovely coachwork of the coupé & cabriolet and a surprising number of these have been built although the standard of the engineering has varied, not all interpolating the 300 SEL 6.3's air suspension.  The finest of the breed were built by Wisconsin-based Karl Middelhauve (1932-2026) and while the term "guru" is these days tossed around entirely too much, truly Karl Middelhauve was "the 600 Guru".     

1971 Mercedes-Benz 280SE 3.5 Coupé (converted to a cabriolet).

This is one really to upset the originality police because: (1) it started life as a coupé before a roofectomy was performed, (2) the chrome (actually anodized plastic) wheel-arch moldings were never available on this model and (3) the Fuchs (Bundt) aluminum wheels have been chromed (and may anyway be reproductions, some of which are cast and not forged, as were the originals).  Such is the price premium a cabriolet will command over a comparable coupé, over the years, many have been tempted to cut but exactly to replicate what the factory did is harder than at first glance it seems.  It's not a matter simply of “removing the roof”, a correctly accomplished conversion demanding: (1) structural reinforcements, (2) a folding roof apparatus and (3) different rear-end body panels.  While from the belt-line down the coupé & cabriolet appear visually identical, the Cabriolet required extensive modifications to the underlying platform to compensate for the removal of the structural rigidity provided by the fixed steel roof.

Structural Reinforcement: (1) The cabriolet used a significantly heavier, thicker floor pan with welded-in boxed side members to prevent body flex and “scuttle (cowl) shake” and for those prepared to do things in a way that don’t exactly emulate the look of what the factory did all those years ago, using modern materials and engineering techniques it is now possible to achieve ever greater rigidity with less additional weight, the attraction being the changes remain hidden unless the car is viewed from below (ie on a hoist) or the carpets are removed for inspection. (2) The Cabriolet's windshield pillars (A-pillars) contain internal steel tubes, both to afford additional rollover protection and support the folding top mechanism, a mechanism heavy by the standards of such things.  (3) While the coupés were built with a structural steel shelf behind the rear seats, in the cabriolets this was replaced with a reinforced partition in which is housed the bulk of the folding roof.  (3) Without the roof’s C-pillar, the size and shape of the rear side windows subtly is different and these feature a unique chromed-frame designed to ensure a tight seal against the heavy weather-stripping of the fabric top (on the coupé the glass seals directly).

The multi-layered soft-top:  The Cabriolet’s folding roof is not (in an engineering sense) complex but the construction was both intricate and labor-intensive.  Almost wholly hand-fitted, the mechanism consisted of a padded outer layer, with a thick insulating bombast of horsehair as a middle layer, finished with a tailored interior headliner.

The Rear Body Panel Modifications: In the lower reaches of the conversion industry, this is the most neglected aspect and the easiest way to identify “a fake” although, unless the real thing is parked side-by-side, most would likely not tell the difference unless their eye is keen: (1) The trunk (boot) lid length is physically shorter on the factory-built cabriolets to accommodate the recessed storage well into which much of the soft-top folds meaning (2) the rear-desk-sheet metal (the panel between the back of the rear seat and the trunk opening) is is unique to the cabriolet, featuring a chrome-trimmed latching area for the soft top's boot.   

Mercedes-Benz 770K (W150; 1938-1943), Cabriolet D (top) and Cabriolet F (bottom).

With a variety of coachwork, all the second generation of the Großers (Grosser (Grand Mercedes)) were built on a chassis with a wheelbase of 3880 mm (152¾ inch).  In some four years, only 88 were built, most of which were allocated to senior figures in the Nazi Party, the Wehrmach (the armed forces) and the German state although a handful were gifted to foreign heads of state.  The 770K will forever be associated with Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) because until the outbreak of war the big Cabriolet F was his preferred parade car and one of the quirks in the factory's nomenclature is that while the body-styles Cabriolet A, B, C & D were defined and well-documented, there was a 770K Cabriolet F, but no Cabriolet E.  The W150 Cabriolet F was among the rarest of the 770Ks with only five made (the distinction the additional rear window in the passenger compartment).  The jump in the factory's designations from "D" to "F" obviously skipped "E" and because that didn't seem the typically precise German way of doing things, there was speculation that another type of open coachwork had been planned (though not necessarily on the 770K chassis) but never built because of the outbreak of war in 1939.  That's not impossible (some records were lost during the war) but the archives for the period have revealed nothing to support the speculation and the sometimes repeated assertion the "Cabriolet F" label was an allusion to "Führer" (the car's most infamous customer) is simply wrong because the designation first was used in the 1920s and was applied to the previous 770 Großer, the W07 (1931-1938).  The factory seems never to have commented on the "missing Cabriolet E" although, despite having a great sense of history, it doesn't much dwell on the company’s relationship with the state and party between 1933-1945.

Wedding ceremony day: Hermann Göring & Emmy Sonnemann, Berliner Dom (Berlin Protestant Cathedral), 11 April, 1935.

Curiously, the wedding car used by Hermann Göring (1893–1946; leading Nazi 1922-1945 and Reichsmarschall 1940-1945) for his (second) marriage to Emmy Sonnemann (1893-1973) was a Mercedes-Benz 500 K Cabriolet C and the photographs do suggest things were a little cramped once his corpulent form had been wedged into the back seat though his more slender bride looked content.  One of the grand public spectacles the Nazi regime (1933-1945) used as propaganda devices, the wedding received blanket coverage in newspapers and, for the following three days, each movie shown in German cinemas was preceded by a “newsreel” segment of “edited highlights” from the happy day.  That would have been a good “catch-up” for Germans unlucky enough not to have been able to listen to the live radio broadcast of the entire ceremony , carried over a then still novel “national hook-up”.  Adolf Hitler served as best man and, in an experience unfamiliar to both him and the groom, neither were the centre of attention, eyes of the audience and lens of the photographers alike focused on the bride.

General Göring wore a Luftwaffe (German Air Force) uniform in a new grayish-blue fabric chosen for the occasion while the bride was dressed in a heavy white satin gown (cut in the then fashionable “Gretchen fashion”) with wide puffed sleeves ending in tight-fitting cuffs.  The train was relatively short and born not by girls (as was then customary) by boys of the HJ (Hitlerjugend (the Hitler Youth)), possibly a deliberate adoption of a practice then usually restricted to royalty and the aristocracy.  From the cathedral, the motorcade travelled the short distance to the Deutsche Oper Berlin (Berlin Opera House).  As one of the party’s leading WAGs (wives & girlfriends), Frau Göring made a good start in staking her claim to the (unofficial) title First Lady des Reiches (First Lady of the Reich), serving as Hitler's hostess at many state functions.  It was however a keenly contest space and both Anna Elisabeth “Annelies” von Ribbentrop (née Henkell 1896-1973), wife of Joachim von Ribbentrop (1893–1946; Nazi Foreign Minister 1938-1945) and (especially) Johanna Maria Magdalena "Magda" Goebbels (née Ritschel 1901-1945), wife of Dr Joseph Goebbels (1897-1945; Nazi Minister of Public Enlightenment and Propaganda 1933-1945) sought the honor and both were adept at Masonic-like plotting & scheming.  Frau Göring’s chances of success became doomed after Eva Braun ( 1912–1945) complained to Hitler that she was “mean to her” so the invitations “dried up” something that didn’t much worry her husband because although regarded almost to the end as Zweiter Mann des Reiches (Second Man of the Reich), he was never part of Hitler’s “inner social circle”.  Although the exact nature of their relationship remains contested, being the Führer’s concubine, Eva Braun could of course never be the Reich’s “First Lady” (her very identity was close to a state secret and she was unknown to most of the population) but, in the final hours of her life, she did gain the satisfaction of being made “Frau Hitler” so there was that.  Of course, long before that low-key wedding in the Führerbunker, the course of the war had meant becoming undisputed First Lady des Reiches was no longer the prize it once was, so what Eva Braun gained was something of a withered garland.

Gretchen fashion: Not many women on the high street dressed quite like this but the elements did appear in everyday garments.

“Gretchen fashion” (or “Gretchen-look”) was a term used for a fashion phenomenon much identified with post-Weimar Germany; like many such trends, it was a blend and the components were (1) traditional wholesomeness and (2) international glamourThe first element was a reaction against the perception of Weimar as “decadent” (although that was always overstated and applied only to a tiny, highly visible minority), thus the choice of the name “Gretchen” as something archetypically German and most associated with modest, pure, rural woman (certainly not “rootless cosmopolitans”).  Nazi-era propaganda attempted to “nudge” women towards a makeup-free life focused on “…the three Ks - die Küche, die Kirche, die Kinder (kitchen, church, and children), a phrase that first became popular during the second half of the nineteenth century but many women knew there was a variant with a fourth “K”: Kleider (Clothing) and while the rustic look was adopted, the Gretchen-look emerged as a hybrid that owed as much to Hollywood as Hannover.  Dresses shifted away from the boxy, drop-waist 1920s flapper silhouette and used instead fabrics cut on the diagonal (the bias cut) to elegantly skim curves and flare gently at the hem.  Weimar’s characteristic angularity and androgyny almost vanished (although the hats were too stylish to be forgotten and were carried-over), replaced by a classic hourglass silhouette, high, natural waistlines returning, often emphasized with slender belts or subtle ties with hemlines at mid-calf, tea-length or floor-length depending on the time of day.  A simplicity of line was dominant but delicate ruffles, puff sleeves and inventive (sometimes even asymmetric) necklines decorated with tie-neck bows or fabric flowers could be used to compliment feminine prints featuring romantic florals or polka dots.  Of course, it was also the art deco era and those motifs along with bold stripes often were seen.  Some in the Nazi Party may have aspired to make the country a totalitarian state but frocks proved a tough opponent and, defying their Führer, women still wore red lipstick, plucked their eyebrows into arches and varnished their nails.

Wedding day of Crown Prince Naruhito & Masako Owada san, Rolls-Royce Corniche III Convertible, 9 June, 1993.  The crown prince was notably more svelte than General Göring.

Because a bride (in wedding gown) will need to step through a fairly small gap when exiting (often while being photographed), a two-door cabriolet does seem a strange choice as a wedding car and why one of the big 770K Cabriolet F Open Tourers wasn’t used doesn’t seem anywhere discussed and of the many questions directed at Göring during his week-long cross-examination at the Nuremberg Trial (1945-1946); understandably perhaps, neither prosecution or defense counsel raised the matter so it’s left to speculation.  It may be the bride wanted something “more romantic” and “less masculine” so there would be the connotation of her “marrying the man rather than the state” and while that’s wholly fanciful, it does explain the seemingly inexplicable.  The use of a two-door cabriolet for a “state” wedding proved however not unique, Japanese Crown Prince Naruhito (b 1960, Emperor of Japan since 2019) appearing in a 1990 Rolls-Royce Corniche III Convertible (by then the factory had ceased calling them DHCs (drophead coupé) although in the twenty-first century DHC would get a nostalgic revival) for his wedding in 1993 to Masako Owada san (b 1963).  It was one of only two public appearances for the Corniche, later retired and replaced by a Toyota Century Royal with one-off four door cabriolet coachwork, something that doubtless will please brides in future weddings associated with the Chrysanthemum Throne.  Compared with 1935, there was by 1993 more material for content providers (then serving almost exclusively television and print media) but the crown prince’s wedding was still a major event (the day declared a national holiday) and, with the country having entered the first of its “lost decades”, the spectacle must have been a relief from tales of economic gloom.

How to really make a statement on one's wedding day: 1993 Rolls-Royce Corniche IV in red, on red, on red.

Although in the English-speaking world the traditional color for wedding cars is white (or a close variant such as cream), in Japanese culture both black and white vehicles are used and there are even specialized Hanayome Taxis (Bridal Taxis) in which the left side of the roof mechanically swings upward so ingress & egress can be elegant with no risk of disturbing intricately constructed “big hair”.  Usually, in vivid red, Kotobuki (congratulations; longevity; good fortune) banners appear on the sides of the wedding cars as a warning to other traffic of the vehicle’s “special purpose”.  One Japanese “wedding superstition” enforced with especial strictness is that a bridal car must never shift into reverse gear because “backing-up” symbolizes “returning home” (ie a looming divorce).  One famous mid-twentieth century tradition that has faded is the Yomeiri (Dowry) Truck, most associated with the Nagoya region.  There, the wedding motorcade was a convoy of trucks used to transport the bride's dowry and furniture to her new home, the vehicles wrapped in festive red-and-white Kohaku maku (striped banners).  Most symbolically, on the bed of the last truck was the newlywed’s brand-new car, wrapped in a large, bright red ribbon.  For the crown prince and princess, their traditional Shinto ceremony was conducted at the Kashiko-dokoro (Shrine of the Sun Goddess Amaterasu) within the grounds of the Imperial Palace grounds in Tokyo and while there were no dowry trucks (the palace already fully-furnished with microwave ovens, toasters and such), the Rolls-Royce was one of 46 vehicles in a motorcade stretching slightly beyond a quarter-mile (402 metres).

Not even Göring matched that scale although, being head of the Luftwaffe, he was able to arrange a fly-past of dozens of fighter aircraft, timed with Teutonic precision to appear over the cathedral just as the couple were walking down the steps to their waiting cabriolet.  The sybaritic Goering gathered titles as enthusiastically as later he would loot Europe of artworks; as well as heading the Luftwaffe, he was Premier of Prussia, Reich Minister of Aviation, general in command of anti-aircraft artillery, general of fliers, Grand Master of the Hunt, Master Forester of Germany, President of Reichstag, chief of the Prussian secret police and Director, State Theatres & Operas (in that capacity he granted Frau Sonnemann the title “State Actress by appointment”) so it wasn’t difficult for him to arrange “stuff for the wedding”.  Hundreds of thousands of Germans (not all of the Berliners) lined the Wilhelmstrasse (Wilhelm Street) and Unter den Linden (best translated as “Boulevard of the Lime Trees”) from the chancellery to the cathedral and seldom can a wedding have seen so men in such a variety of uniforms (at attire then adored by Germans).  Manpower not being a resource-allocation problem for Göring, some 30,000 young men from a variety of Nazi organizations formed a double row in order to keep the streets clear and, with the expected military precision, they stood at attention with right arms raised in the “Hitler salute” as the wedding motorcade passed by.  In a legal sense, the marriage had taken place the day before in a civil ceremony at Berlin City Hall, bride and groom signing the necessary paperwork confirming they were of “pure Aryan stock and free from hereditary disease” (millions of those not either in the ten years to follow being murdered by on Hitler’s orders) so the rituals in the church were essentially ceremonial and performed for the benefit of God rather than the state.  Reich Bishop Ludwig Mueller (1933-1945) officiated, choosing the New Testament’s Book of Revelation for his text (“Be thou faithful unto death and I will give you a crown of life.”):  Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life.  Revelations 2:10 (King James Version of the Bible (KJV, 1611)).

The car most famously associated with Göring was also a Mercedes-Benz convertible (though not a cabriolet): a 1937 540K (W29) Special Roadster.  The earlier 500K Special Roadster came to be called “the brightest glint of a golden age” and while the 540K SR wasn’t quite as rakish as its slightly smaller predecessor, that may have been a good thing because modifications had to be made the 540 to ensure Göring was “able to fit behind the wheel” and even then, things were “tight”.  His 540K SR was nicknamed das Blaue Gans (the Blue Goose) because Göring ordered it his favourite shade of Luftwaffe Blaue (used for the underside of reconnaissance aircraft) and he was sufficiently fond of the hue to have one of his (many) Reichsmarschall uniforms cut in a fabric dyed the same color.

Appointed in 1933 by Hitler to the newly created office of Reichsbischof de Deutsche Evangelische Kirche (Bishop for the Reich of the German Evangelical Church), Mueller, a Lutheran priest and undistinguished theologian had no obvious qualifications for the role other than being a devoted Nazi but for the Führer, that was enough.  In office, Mueller, even by the slight standards of the regime’s minor functionaries, proved singularity inept and far from uniting the German protestant churches as was his designated task, he proved a schismatic influence.  By 1937, it was obvious to Hitler he’d “backed a dud” and increasingly he abandoned his use of carrots in church matters, resorting to the stick “when required” but otherwise becoming indifferent, seemingly resigned to the party’s state of “semi-peaceful” co-existence with the churches.  Typically, despite his conspicuous failure, Mueller wasn’t dismissed but simply ignored, his sycophancy and repeated attempts at ingratiation with the regime proving pointless.  Still, he deserves credit for having been prophetic in his choice of text for Göring’s wedding although whether “Defendant Number One” at the Nuremberg Trial much dwelt on the words during the months he spent in his cell or as he stood to hear the IMT’s (International Military Tribunal) president sentence him to be hanged, isn’t known.

Exoskeleton & Endoskeleton

Exoskeleton (pronounced ek-soh-skel-i-tn)

(1) In zoology, an external covering or integument, any hardened external structure, as the shells of crustaceans or the scales and plates of fishes and reptiles, especially when it is of the nature of bone.

(2) All hard parts, such as hair, teeth, and nails which develop from the ectoderm or mesoderm in vertebrates (generally used only in technical literature).

(3) A wearable robotic machine used for aided or augmented mobility.

1841: The construct was exo- + skeleton.  The prefix endo- was used as a word-forming element meaning "inside, within, internal.  It was from the Ancient Greek νδον (éndon) (within; inner; internal) from the primitive Indo-European en-do- (an extended form of the root en (in)).  Skeleton was from the New Latin skeleton (bones, bony framework of the body), from the Ancient Greek skeleton soma (dried-up body, mummy, skeleton), from the neuter of σκελετός (skeletós) (dried up, withered, dried body (and as a noun: parched; mummy), from σκέλλω (skéllō & skellein) (dry, dry up, make dry, parch), from the primitive Indo-European (s)kelha- (to parch, wither); related was the Ancient Greek σκληρός (sklirós) (hard).  Exoskeleton is a noun; the noun plural is exoskeletons or exoskeleta.

Skelton was an early variant form.  The noun use of Greek skeletos passed into Late Latin as (sceletus), hence the French squelette and the rare English skelet (1560s), the Spanish esqueleto & the Italian scheletro.  The meaning "bare outline" was first recorded circa 1600; hence the term "skeleton crew" from 1778 used to describe minimal staffing, the skeleton key a similar allusion to some of a structure being removed.  The phrase "skeleton in the closet" (source of secret shame to a person, family or institution) is from 1812 and thought an adoption from the imagery in the fable Bluebeard (1697) by Charles Perrault (1628-1703). Exoskeleton was in 1841 coined by by English paleontologist Sir Richard Owen (1804–1892).  Exoskeleton has become more widely used in recent years because of the interest in fields such as engineering, robotics and medicine in using external structures, often to augment or replace human functions.  As early as the 1960s, the "exoskeleton look" became fashionable among architects who would no longer conceal features like plumbing pipes

Trilobites

Trilobite variants.

Trilobite (pronounced try-low-byte) translates literally as “three lobes".  Often casually referred to as bugs or sea-bugs, in taxonomy, all trilobites actually belong in the class of trilobite in the phylum arthropod and within the class are ten orders.  It’s not known how many species of trilobites existed but almost 21,000 have thus far been identified in the fossil record, their numbers and variety leading them to be regarded as one of history’s more successful animals.  They inhabited all the seas and oceans and endured some three-hundred million years, surviving several mass-extinction events.  Their long duration, their structure and living habits meant they became a common and frequently discovered fossil, noted since antiquity although the first attempt scientifically to classify one seems to have been by Wan Shizen of China who, in 1689 described trylobite pygidia (tails) as "batstones".  The first known scientific drawing was by Welsh botanist, the Reverend Edward Lhuyd (1660-1709) whose sketch of a trilobite was published in "The Philosophical Transactions of the Royal Society.  The drawing, now classified as being a Ogygiocarella debuchii, was then (not unreasonably), called the "flatfish".

Truly ancient, trilobites pre-date the Cambrian explosion (some 540 million years ago) and went extinct only towards the end of the Permian extinction event (some 250 million years ago) which ended the Paleozoic age which had lasted some 290 million years.  However, the earlier events took their toll, a few orders vanishing after the Ordovician event (some 445 million years ago) while the Devonian event (some 370 million years ago) removed all but one order, that last survivor dying out in the Permian event.  Why such a successful and prolific creature could not endure these extinctions remains a debate, the more popular theories including (1) environmental change happening with such rapidity there was no time for evolutionary adaptation and (2) the needed sources of nutrition vanishing because organisms lower in the food-chain went extinct.  All shared the same basic structure, having three lobes: a left pleural, a middle axial and a right pleural lobe, their bodies divided into a cephalon (dead), thorax (middle), and pygydium (tail).  Trilobites had a thick, protective exoskeleton which formed a hard calcite shell, something like that of the modern crab and is the reason for their frequency in the fossil record, the exoskeletons usually the only part to survive although, in the rare cases where certain surrounding conditions exist, traces of soft tissue such as antennae can survive fossilization.  As a trilobite grew, it molted its exoskeleton, and many of the fossils which exist are molted frames rather than dead creatures.

Before & after avian intrusion: 1952 Mercedes-Benz 300 SL (W194), Carrera Panamericana, Mexico, November 1952.

In nature, exoskeletons evolved over thousands of generations through the interplay of natural selection and adaptation to prevailing environmental conditions but with man-made objects such things, in cases of immediate need, can within hours be fashioned.  Returning to the circuits for the first time since the end of World War II (1939-1945), Mercedes-Benz had enjoyed immediate success with the new 300 SL (W194) race car which, despite being underpowered, proved its mettle with a combination of robustness, reliability and outstanding aerodynamics which both increased performance and improved fuel economy.  The W194, ten of which were built, is often referred to as “the first gullwing” (although the configuration had in 1939 been seen on a one-off Bugatti and was not uncommon in aviation and nautical use) but the distinctive doors were introduced only after those enforcing the regulations of sports car at Le Mans ruled the 300 SL’s original “doors” were no such things and were merely “elaborately framed windows”.  With re-designed doors fitted, the W194 promptly delivered the factory a 1-2 result in the 1952 24 hour endurance classic.

1952 Carrera Panamericana: The winning 300 SL in the factory museum.

Concluding things that year was the third Carrera Panamericana, a gruelling endurance event of eight stages over some 3,100 km (1,925 miles) between 19-23 November.  With typical thoroughness, the factory shipped three W194s along with a large support staff and all was going well until the lead car collided with a large bird (contemporary articles variously reporting the unfortunate creature as a vulture or buzzard) which smashed through the windscreen at an impact speed in excess of 215 km/h (135 mph), stunning the co-driver and leaving him bloodied.  Shook awake, he recovered and when the car reached the service point a new windscreen was fitted and, as a precaution against other vultures (or whatever) seeking vengeance, eight metal bars were fitted, the ad-hoc birdcage designed to keep them out, not in.  Without further avian “events”, the W194 repeated the result from Le Mans by finishing 1-2 and, fully restored, the winning car is part of the collection of the Mercedes-Benz Museum in Stuttgart.

1968 London-Sydney Marathon: The 1968 Porsche 911S which finished fourth (left) and after a full restoration (right).  A zoologist would insist this is only a "semiexoskeleton" on the basis of the partial coverage. 

As all in the Northern Hemisphere understand, in Australia, on land, sea & air, all the wildlife will try to kill you.  Noting this, when Porsche’s competition department prepared its three entries for the 1968 London-Sydney they limited their concern about sharks and crocodiles to a single paragraph in the drivers’ instruction sheets and decided the main threat to the cars were wandering “giant” kangaroos and low-flying wedge-tailed eagles (a bird with a wingspan wider even than Mexico’s vultures).  The first event of its type in the modern era, the 1968 London-Sydney Marathon spanned half the globe over a distance of 12,237 miles (16,934) and the route shows how times have changed, stages in Iran & Pakistan included; neither country now places many organizers of events would include in their itineraries but in 1968, kangaroos were still deemed more a threat than terrorism.  Accordingly, the factory designed a kind of exoskeleton, a robust external roll cage which essentially was the W194’s “birdcage” but “on steroids”.  As originally conceived, the structure had been of more modest proportions and while the final result may look like “overkill”, things were “beefed up” following one of the drivers writing off a rented VW Beetle after colliding with a kangaroo during pre-event testing in Australia.  Impressed by the extent of the damage, the engineers produced an impressively strong protective cage, content that whatever else might go wrong, it wouldn’t be a kangaroo which ended the venture.  Porsche 911S #58 finished fourth, victory going to a Hillman Hunter #75, one of the more improbable machines to win an international endurance event.

1968 London-Sydney Marathon: The winning 1968 Hillman Hunter (left) and restored 1967 Pakyan 1725 (right), the Iranian variants often noted for their additional bling.  Unlike the cautious Germans, most teams fitted only rudimentary additional protection against kangaroos and such; some ruefully later casting envious glances at Porsche's exoskeleton. 

In fairness, though an unlikely competition car, the Hillman Hunter (the “mainstream” model in the “Arrow” range which would sold also as “badge-engineered” Sunbeam, Singer & Humber variants) was a success in many countries, lasting in Europe from 1966 until 1979 although its most extraordinary longevity was achieved in the Islamic Republic of Iran.  In 1966, during the reign of Mohammad Reza Pahlavi (1919–1980; last Shah of Iran 1941-1979) assembly from CKD (completely knocked down) packs had begun with the car sold as the Paykan (پیکان, Romanized as Peykān and literally “Arrow”) and unlike many things, it survived the 1979 revolution to continue to flourish under the rule of Grand Ayatollah Ruhollah Khomeini (1900-1989; Supreme Leader, Islamic Republic of Iran, 1979-1989), full local manufacture starting in 1985.  Although theologically uncompromising, there’s no record of the Imam having complained of the presence on his assembly lines of a product from شیطان کوچک (Sheytān-e Koochak) (the UK & Israel being “Little Satan” and the US شیطان بزرگ (Sheytān-e Bozorg) “Great Satan” although in the West the terms are often misunderstood because in flavour of Shia Islam practiced in Iran, Satan is a pathetic rather than fearsome figure).  When in 1979 Grand Ayatollah Ali Khamenei (1939-2026; Supreme Leader, Islamic Republic of Iran 1989-2026) became supreme leader, the Pakyan carried on and although production of the salon finally ended in 2005, the pick-up variant continued to be sold for another decade, the last not leaving the line until almost 50 years after the first Hunter was sold in the UK.  From the modest Hunter, the ayatollah's got their money's worth.

Exoskeleton cars

MVE Exocet (left) & Exomotive’s Exocet Sport V8 (right).

Exoskeleton vehicles are numerous on farms, mine-sites and such but rarely seen on public roads.  They do though have a niche for those who want something which sacrifices just about everything (aerodynamics, weather protection, doors etc) for the nimbleness only extreme light-weight can deliver.  An example is the MVE Exocet, released for public sale in 2010.  It’s an inventive approach to the kit-car concept and takes the classic front-engined, rear-wheel drive approach, based on Mazda’s Miata (the MX-5, introduced in 1989 and a kind of clone of the Lotus Elan of the 1960s but without the problems), the advantage with the Japanese platform being its unusual sub-frame which permits the removal of the body, leaving the engine, drive-train and suspension as a rolling assembly to be transplanted to the Exocet chassis.

Because of the light weight, even when using sensible four-cylinder engines the Exocet delivers high-performance but the Americans in particular can’t resist the idea that just about any car can be improved by the installation of a V8 and quite outlandish power to weight ratios are possible.  An indicative example of Exomotive’s Exocet Sport used a 525 horsepower (LS3) version of one of the later evolutions of the small-block Chevrolet V8 which, fully fueled, weighed in at 1690 lb (767 kg, the 2026 Formula 1 regulations set a minimum dry-weight (ie excluding fuel) of 768 kg).  Because it possible to buy, off the shelf (as a “crate” engine), V8 engines with about the same power as a F1 power-plant generates, although there was be something a weight penalty, the potential does exist to build a two-seater roadster with a similar power-to-weight ratio and there are jurisdictions which even allow such a thing to be registered for use on public roads.  Opinions would differ on whether such a build is a good idea but the little machines, if the V8 was tuned more for low and mid-range torque rather than ultimate power, would seem to have great potential in competitions such as short-course events and hill-climbs although the dubious aerodynamics would render it less suited to high-speed tracks.

Art and money: Porsche 934 (left) by Benedict Radcliffe (b 1976) sold for US$249,002 while Comedian (a banana duct-taped to the wall, right) by Maurizio Cattelan (b 1960) realized US$6.2 million.

The exoskeleton concept inspired English artist and sculptor Benedict Radcliffe to create a number of small scale tubular steel sculptures in the shape of cars including the Lancia Stratos (1973-1978), Lamborghini Countach (1974-1990) and Ferrari F40 (1987-1992), mostly powdered-coated in lurid colors.  Usually, they sell for several thousand US dollars but in early 2025, one in 1:1 scale in the shape of a Porsche 934 sold for US$249,002; in a nod to history, it was painted in the same fluro-orange used for the Jägermeister livery used for the race cars in 1979-1977 and rolled on period-correct centre-locking BBS wheels shod with Avon slick tires.  At that price, it was little different from what one would pay for a new Porsche 911 GT3, straight from the showroom floor.  Still, it’s less than the US$1.5 million which is typical of what’s been paid in recent years on the rare occasions a 934 is offered for sale.  Produced between 1976-1977, Porsche built 31 934s, simply for the purpose of creating a version of the 930 (the 911 Turbo, 1975-1978) which would comply with the FIA Group 4 (GT Cars) rules (the 935 was the companion Group 5 (Special Production Cars) project).  The art market cannot be assessed with any form of conventional metrics but in paying a quarter-million odd for a tubular structure, one gets quite a lot compared with the Italian visual artist Maurizio Cattelan’s Comedian, (a banana duct-taped to the wall); a couple of months earlier, at auction, it had gone under the hammer for US$6.2 million.

Endoskeleton (pronounced en-doh-skel-i-tn)

(1) In zoology, the internal skeleton or framework of the body of an animal (generally the bony or cartilaginous skeleton of vertebrates).  Certain invertebrates, such as sponges and echinoderms, also have endoskeletons.

(2) For most (non-technical) purposes, a synonym for skeleton.

1838: The construct was endo- + skeleton  The prefix exo- was used as a word forming element in words of Greek origin meaning "outer, outside, outer part" and was used from the mid-nineteenth century.  It was from the Ancient Greek ξω (éxō) (outer; external) and was related to ex (out of).  Endoskeleton is used almost exclusively in the biological sciences.  For most general purposes, it’s synonymous with skeleton which is the default assumption of use because it’s familiar from humans and most familiar animals.  Endoskeleton is a noun; the noun plural is endoskeletons or endoskeleta.

The nicely defined shoulder blade and ribcage definition of Lindsay Lohan's endoskeleton.

The word endoskeleton may not have been needed had all creatures on earth had “conventional” skeletons like humans, cats, dogs, fish and such; there would have been just “skeletons”.  Of course, architects and engineers likely would have been unable to resist coining “exoskeleton” there seems no better word to describe an externally-located superstructure.  Both an endoskeleton and exoskeleton are structural frameworks to some degree (sometimes wholly) supporting and shaping an organism’s body and which form an animal evolved to adopt was a product of history and environment.  That’s best illustrated by those with hard outer shell (really the ultimate exoskeleton) which functions as a kind of armor-plate.  Among man-made objects, both models are used and easily identified although exoskeletons (such as the futtocks in nautical design) probably are more common in anything with a “skin” including buildings, aircraft and ships.

Endoskeleton cars

The Birdcage: The Maserati Tipo 60/61 (chassis #2549).

Endoskeleton cars are far from uncommon but some make the concept more obvious than others.  The Maserati Tipo 60/61 (1959-1961) gained the nickname “Birdcage” (by which it’s almost always known) because observers were much taken with the delicacy of the construction.  By the late 1950s, space-frames had become familiar to race-car builders but they were usually robust-looking arrangements whereas Maserati had rendered an intricate latticework of some 200 chromoly steel tubes welded often in triangulated form in the points of highest stress, the design delivering both lightness and rigidity.

Mercedes-Benz 300 SLR (W196S, upper) & 300 SL (W198, lower).

One of the reasons the Maserati’s skeleton looked so delicate was that the space-frame had become associated with Teutonic-flavored construction like that used by Mercedes-Benz for its 300 SL & 300 SLR.  Both shared the same method of construction but despite the names and the the visual similarity between the two, there were few common components beyond the nuts, bolts & screws.  The 300 SL (W198; 1954-1963) was a road car while the SLR (W196S; 1955) was a lengthened version of the W196R Formula One Grand Prix car with a sexy body and an enlarged (though somewhat detuned) straight-eight engine.  Despite appearing much more substantial than the Maserati's birdcage, the German space-frame was remarkably light.
