Nit

Nit (pronounced niht)

(1) The egg of a parasitic insect, especially of a louse, often attached to a hair or a fibre of clothing or the young of such an insect.

(2) In physics, a unit of luminous intensity equal to one candela per square meter (abbreviation: nt).

(3) Slang term to describe those thought unintelligent (a clipping of "nitwit").

(4) As "nitpicker", a description of those who look for minor, unimportant faults or defects (also used in computing as a slang term for debuggers, those who specialise in finding errors in code).

(5) In digital electronics, an increment of data equal to 1.44 binary digits.

Pre 900: From the Middle English nite, from the Old English hnitu, from the Proto-Germanic hnits; cognate with the Dutch neet, the German niss & nisse and the Norwegian nit.  Root was the primitive Indo-European nid, ḱnid & ḱonid; related were the Scottish Gaelic sneadh, the Lithuanian glìnda, the Polish gnida, the Albanian thëri, and the Ancient Greek κονίς (konís).  As used to describe brightness, the use of nit is derived from the Latin nitor (brightness) & nitere (to shine) and was created in the early 1950s as a useful way of defining the luminosity of television displays.

Candlepower

Competition cars used at night need many nits.  The light generated by the array of auxiliary headlamps used to be measured in the hundreds of thousands of candlepower.

Now obsolete, candlepower (cp) was the historic unit of measure for luminous intensity.  It expressed luminosity (level of light intensity) relative to the light emitted by a candle of a specific specification and was first defined in the UK by the Metropolitan Gas Act (1860).  The candle chosen was made of Spermaceti, extracted from the heads of sperm whales.  Under the auspices of the Commission for Illumination (Commission Internationale de l'Eclairage (CIE)), the standard was revised in 1921 to use a carbon filament incandescent lamp and again in 1937 using liquid platinum.

In 1948, the International Standards Organization (ISO) introduced an international standard (SI) named candela (cd) which replaced candlepower, one candlepower being about 0.981 candela; because the values were close, in general use the word candlepower is still often used interchangeably with candela although the latter is the standard in scientific discourse and most industrial applications.  The nit (nt) is a non-SI name also used for this unit (1 nt = 1 cd/m²).  It lacks the transportability of precision needed for scientific use but is ideal for describing the brightness of display devices such as monitors or televisions.  Modern consumer desktop LCD displays had a luminance between 200-350 nits and high-definition LED televisions and display arrays range from 450 to around 1500 nits.  One use of NIT as an acronym was the high-school slang "new in town" so, just arrived from Africa (it was never made explicit which country),  Cady Heron (Lindsay Lohan) in Mean Girls (2004) was a NIT. 

Coronet

Coronet (pronounced kawr-uh-nit, kawr-uh-net, kor-uh-nit, or kor-un-net)

(1) A small crown.

(2) A crown worn by nobles or peers (as distinct from those worn by sovereigns).

(3) A crown-like ornament for the head, as of gold or jewels.

(4) An ornament, tending to the pedimental in form, situated over a door or window.

(5) The lowest part of the pastern of a horse or other hoofed animal, just above the hoof.

(6) In heraldry, a crown-like support for a crest, used in place of a torse; also called crest coronet.

(7) The margin between the skin of a horse's pastern and the horn of the hoof.

(8) The knob at the base of a deer's antler.

(9) The traditional lowest regular commissioned officer rank in the cavalry (the equivalent of an ensign in the infantry or navy).

(10) Any of several hummingbirds in the genus Boissonneaua.

(11) A species of moth, Craniophora ligustri.

1350–1400: From the Middle English crownet & corounet, from the Middle French couronnette, from the Old French coronete (little crown) a diminutive of corone (crown) from the Latin corona (third-person singular present active subjunctive of corōnō) (crown), from the Ancient Greek κορώνη (korṓnē) (garland, wreath; a type of crown; a type of sea-bird, perhaps shearwater; a crow; anything curved or hooked (like a door handle or the tip of a bow).  Related in form, if not always function are diadem, wreath, crown, chaplet, circle, tiara, headdress, headband & anadem (a headband, particularly a garland of flowers).  Coronet is a noun; the noun plural is coronets.

Lindsay Lohan in coronet: Mean Girls (2004).

Crowns and coronet are both types of headgear worn as symbols of authority but there are technical differences between the two.  The crown is the traditional symbolic headpiece worn by a monarch and (in some cases) certain other members of royal families.  Fabricated usually from precious metals and adorned with jewels, crowns are by convention taller and more ornate than coronets but this is not an absolute rule and the symbolism of a crown as something representing sovereign power and regal authority doesn’t rely on its size.  Despite that, coronets tend to be smaller, less elaborate versions of crowns and they’re worn by members of the nobility who do not hold the rank of monarch and the consort of a monarch.  According to authoritative English sources, the general specification for a coronet dictates a small crown of ornaments  fixed on a metal ring and, as a general principle, a coronet has no arches and unlike a tiara, it wholly encircles the head.  Helpful as that may be, coronets in the wild are obviously rare (although that depends on the circles in which one moves) but commonly see as rank symbols in heraldry, adorning a coat of arms.  More opportunistically, they’re a popular symbol used in commerce.

Coronets of the United Kingdom.

In the UK, a country where there are more coronets than most, those worn by members of the House of Lords are of a defined designed according to the notch on the peerage one inhabits but surprisingly, they’re worn only for royal coronations so the 2023 event will be their first appearance en masse since 1953.  Outside of royalty, they were once exclusive to dukes but the right was granted to marquesses in the fifteenth century, to earls in the fifteenth, to viscounts (of which there are surprisingly few) in the sixteenth and barons in the seventeenth.  Coronets may not bear any precious or semi-precious stones.

1959 Dodge Silver Challenger

Chrysler’s Dodge division used the Coronet nameplate in a way typical of Detroit’s mid-century practices.  Between 1949-1959 it was a full-sized Dodge, beginning as a top-of-the-range trim before in 1955 being shifted downwards, seeing out its first iteration as an entry-level model.  One mostly forgotten footnote of the first Coronets is the 1959 range saw the first use of the Challenger name.  In 1959 the Coronet-based Challenger was an early example of a model bundled with a number of usually optional accessories and sold at an attractive discount.  The concept would become popular and the Challenger name would later be twice revived for more illustrious careers as pony cars (although the first attempt (1969-1974) was a financial disaster, the cars now much sought-after which, in their most desired configurations trade in the collector community well into six figures with the odd sale above US$1 million).

1979 Dodge Challenger (a "badge-engineered" Mitsubishi).

Although the Mopar crew don't much dwell on the matter, between 1978-1983, Dodge applied the Challenger name to a "captive import" (the then current term describing an overseas-built vehicle sold under the name of domestic manufacturer through its dealer network), a Mitsubishi coupé sold in other markets variously as the Sapporo, Lambda and Scorpion.  Although somewhat porcine (until a mid-life facelift tightened things up), it was popular in many places but never achieved the same level of success in the US (where Plymouth also sold it as the Sapporo), even though that was where the "personal coupé" had become a very lucrative market segment.   

1969 Dodge Hemi Coronet.  By 1969 the writing was on the wall for engines like the Hemi and just 97 Coronet hardtops and 10 convertibles were built.  In 1970, when the last two-door Coronets were made, production had dropped to 13 hardtops and a solitary convertible.

The Coronet’s second run was as an intermediate between 1965–1976 and it’s the 1968-1970 models which are best remembered, based on the corporate B-body platform shared with the Plymouth Belvedere and Dodge Charger.  Plymouth gained great success with their take on the low-cost, high-performance intermediate when they released the Road Runner, a machine stripped of just about all but the most essential items except for its high performance engines, including the 426 cubic inch (7.0 litre) HEMI V8.  It was a big hit, the sales wildly exceeding projections and it encouraged Dodge to emulate the approach with the Coronet Super Bee although for whatever reason, it didn’t capture the imagination as had the Road Runner and in the three seasons both were available, sold less than a third of its corporate stablemate.

1967 Dodge “Road Runner” advertisement.

Curiously though, Dodge may have missed what proved to be the priceless benefit of using the Road Runner name, in 1967 running advertisements for the Coronet R/T (“Road & Track” although “street & strip” would have been closer to the truth), which used the words “Road” & “Runner” although spaced as far apart as perhaps the lawyers advised would be sufficiently distant to avoid threats of litigation.  Plymouth solved that problem by legitimization, paying Warner Brothers US$50,000 for the Road Runner name and the imagery of the Wile E Coyote and Road Runner cartoon depictions, spending a reputed (though unverified) additional US$10,000 for the distinctive "beep, beep" horn sound, the engineering apparently as simple as replacing the aluminium strands in the mechanism with copper windings.

Carp

Carp (pronounced kahrp)

(1) To find fault or complain querulously or unreasonably; be niggling in criticizing; cavil.

(2) A peevish complaint; to find fault with; to censure; to complain about a fault.

(3) A large, freshwater teleost (of, or relating to the Teleostei (fish with bony skeletons)) food fish of the family Cyprinidae (Cyprinus carpio), characterized by a body covered with cycloid scales, a naked head, one long dorsal fin, and two barbels on each side of the mouth.  It was native to Asia but was widely introduced in tropical and temperate waters; an important food fish in many countries and an introduced invasive pest in others.  There is one .cyprinid genus which tolerates salt water although many at times inhabit brackish water.

(4) Any of various other fishes of the family Cyprinidae; a cyprinid.

(5) In botany, a combining form occurring in compounds that denote a part of a fruit or fruiting body (best known in the form endocarp (the woody inner layer of the pericarp of some fruits that contains the seed).

(6) To say; to tell (obsolete).

1200-1250:  From the Middle English carpen (talk; to speak, to tell (someone something)), from the Old Norse karpa (to brag, wrangle) & karp (bragging) of unknown origin but linked to the Vulgar Latin carpere because of the meaning shift to “find fault with”, under the influence of the Latin carpō.  By the late fourteenth century, the sense had been further refined to mean “complain excessively about minor faults, often petulantly or without reason.  The Latin carpere (literally “to pluck” was used to convey the idea of "to slander or revile”), from the primitive Indo-European root kerp- (to gather, pluck, harvest).  The original sense in English (talk; to speak, to tell (someone something)) was between the mid-fifteenth and early sixteenth centuries maintained in the noun carper (talker), an agent noun from the carp; the modern sense of “a fault-finder” began to prevail from the 1570s.  Thus carping, which in the late thirteenth century was recorded as meaning “talk, speech; talkativeness, foolish talk” and was a verbal noun from the verb also by the 1570s came to be used to impart the idea of “unreasonable criticism or censure”.  The botanical use was from the New Latin -carpium, from the Greek -karpion, a derivative of karpós (fruit).

Among critics, there are clappers and carpers.

The name of the fish was from the late fourteenth century Middle English carpe, via the Old French carpa (the source also of the Italian & Spanish carpa), from either the Middle Dutch or the Middle Low German karpe and cognate with the Old High German karpfo, the Middle Dutch carpe, the Dutch karper, the Old High German karpfo & the German Karpfen (carp).  Although documentary evidence is lacking, some etymologists suggest the origin may be East Germanic (perhaps the unrecorded Gothic karpa) because the fish was in the fourteenth century introduced into English waterways from the Danube.  The Lithuanian karpis and the Russian karp are Germanic loan words but the most attractive name for the fish is doubtlessly the Japanese koi, first noted in 1727.  The ubiquitous goldfish is a type of carp and was introduced to Europe from China where it was native, their natural dull olive skins rendered by selective breeding into silver, red & black as well as the familiar orange.  The phrase “living in a goldfish bowl” dates from 1935 and was used figuratively to suggest a “lack of privacy”, based on the circular bowls in which the domestic pet fish were often kept, affording all a 360^o view of their activities.  The use of the noun gallimaufry (a medley, hash, hodge-podge) to describe various recipes of carp stews is mysterious but presumably related to the many other ingredients included to make the dish more palatable, the freshwater carp not highly regarded compared to the alternatives.  Carp convey a specific sense of the way a criticism is delivered and is subtly different from words like deprecate, condemn, censure, grumble, quibble, complain, criticize or reproach is that it’s held to be something nit-picking or pedantic.  Carp & carper are nouns; carped is a verb and carping is a verb, adjective & noun; the noun plural is carps although, of the fish, carp tends to be used when speaking collectively except when it’s regarding two or more species in which case it’s carps.

In some Australian waterways, carp have become a notable environmental threat, crowding out native species and adversely affecting water-quality because of their mud-sucking ways, causing erosion and killing of trees close to the water’s edge.  Although some water birds benefit from the abundant food source, they’re a rare winner.  The invasive species was introduced to the countries over a hundred years ago but the populations spiked massively after the 1960s when one genetic strain escaped from a fish farm in Victoria and in some places carp now constitute some 90% of the aquatic biomass.  As filter feeders (mud-suckers), they forage in the riverbeds, damaging aquatic plants, a feeding style which induces turbidity in the water, something unsuitable for many native fish.  Carp reproduce quickly, lack natural predators and are highly adaptable, able to take over ecological niches adding further stress to local flora & fauna.

In October 2022, a six-year research project to investigate the potential to introduce a herpes virus to control the carp delivered a final report to the Commonwealth & state governments.  In the national parliament, then deputy prime-minister and minister for Agriculture Barnaby Joyce MP (b 1967; thrice deputy prime-minister of Australia, 2016-date (the gaps due to “local difficulties”)) warmed to the idea of unleashing a venereal disease on “disgusting, mud-sucking carp”.

Gullwing & Gull-wing

Gullwing & Gull-wing (pronounced guhl-wing)

(1) In aviation, an airplane wing that slants briefly upward from the fuselage and then extends horizontally outward (ie a short upward-sloping inner section and a longer horizontal outer section).

(2) Of doors, a door hinged at the top and opening upward (applied usually to cars but can be used in aviation, aerospace and architecture).

(3) Anything having or resembling (extended and partially extended) wings of a gull (and many other birds).

(4) In electronic hardware, a type of board connector for a small outline integrated circuit (SOIC).

(5) In historic admiralty jargon, a synonym of goose wing (a sail position).

Gull is from the Middle English gulle, from the Brythonic, from the Proto-Celtic wēlannā (seagull) and was cognate with the Cornish guilan, the Welsh gwylan, the Breton gouelan and the Old Irish faílenn.  The noun Gull was used (in a cook-book!) to describe the shore bird in the 1400s, probably from the Brythonic Celtic; it was related to the Welsh gwylan (gull), the Cornish guilan, the Breton goelann; all from Old Celtic voilenno-.  Gull replaced the Old English mæw.

The verb form meaning “to dupe, cheat, mislead by deception" dates from the 1540s, an adaptation by analogy from the earlier (1520) meaning "to swallow", ultimately from the sense of "throat, gullet" from the early 1400s.  The meaning was the idea of someone so gullible to “swallow whatever they’re told”.  As a cant term for "dupe, sucker, credulous person", it’s noted from the 1590s and is of uncertain origin but may be from the verb meaning "to dupe or cheat".  Another possibility is a link to the late fourteenth century Middle English gull & goll (newly hatched bird" which may have been influenced by the Old Norse golr (yellow), the link being the hue of the bird’s down.

Wing was from the late twelfth century Middle English winge & wenge (forelimb fitted for flight of a bird or bat), applied also to the part of certain insects which resembled a wing in form or function, from the Old Norse vængr (wing of a bird, aisle etc) from the Proto-Germanic wēinga & wēingan-.  It was cognate with the Danish vinge (“wing”), the Icelandic vængur (wing), the West Frisian wjuk (wing) and the Swedish vinge (“wing”), of unknown origin but possibly from the Proto-Germanic we-ingjaz ( a suffixed form of the primitive Indo-European root we- (blow), source of the Old English wawan (to blow).  It replaced the native Middle English fither, from the Old English fiþre & feðra (plural (and related to the modern feather)) from the Proto-Germanic fiþriją, which merged with fether, from the Old English feþer, from the Proto-Germanic feþrō).  The meaning "either of two divisions of a political party, army etc dates from circa 1400; the use in the architectures was first recorded in 1790 and applied figuratively almost immediately.  The slang sense of earn (one's) wings is 1940s, from the wing-shaped badges awarded to air cadets on graduation. To be under (someone's) wing "protected by (someone)" is recorded from the early thirteenth century; the phrase “on a wing and a prayer” is title of a 1943 song about landing a damaged aircraft.

A Gull in flight (left), inverted gull-wing on 1944 Voight Corsair (centre) & gull-wing on 1971 Piaggio P.136 (Royal Gull) (right).

In aviation, the design actually pre-dates powered flight (1903) by half a millennium, appearing in the speculative drawings of flying machines by Leonardo da Vinci (1452-1519) and others, an inevitable consequence of being influenced by the flapping wings of birds.  There were experiments, circa 1911, to apply the gull-wing principle to some of the early monoplanes in a quest to combine greater surface area with enhanced strength but it wasn’t until the 1920s it began widely to be used, firstly in gliders for some aerodynamic advantage and later, powered-aircraft.  In powered aircraft, the gull-wing offered little aerodynamically but had structural advantages in that it allowed designers more easily to ensure (1) increasingly larger propellers would have sufficient clearance, (2) undercarriage length could be reduced (and consequently strengthened) and (3) wing-spans could slightly be reduced, a thing of great significance when operations began on aircraft carriers, the gull-wing being especially suited to the folding-wing model.  Depending on the advantage(s) sought, designers used either a classic gull-wing or the inverted gull-wing.  The correct form is for all purposes except when applied to the the (1954-1957) Mercedes-Benz 300 SL coupé is the hyphenated gull-wing; only the 1950s Mercedes-Benz are called Gullwings.

1945 Jamin-Bouffort JB.

Cars with gull-wing doors had been built before Mercedes-Benz started making them at scale and the principle was known in both aviation and marine architecture.  One was the 1945 Jamin-Bouffort JB, the creation of French aeronautical engineer Victor-Albert Bouffort (1912-1995) who had a long history of clever, practical (and sometimes unappreciated) designs.  The Jamin-Bouffort JB was a relatively small three-wheeler built using some of the techniques of construction used in light aircraft, the gull-wing doors the most obvious novelty.  Anticipating the 1950s boom in micro-cars, there was potential but with European industry recovering from the war, most effort was directed to resuming production of pre-war vehicles using surviving tooling and there was little interest in pursuing anything which required development time.  Monsieur Bouffort would go on to design other concepts ahead of their time, some of his ideas adopted by others decades after his prototypes appeared.

Bugatti Type 64 with gull-wing body fabricated using original conceptual sketches on 1939 Type 64 chassis.

In 1939, Jean Bugatti drew up plans for the Type 64, a vehicle with gull-wing doors, his sketches an example of the great interest being shown by European manufacturers in aerodynamics, then called usually streamlining.  Although two Type 64s were completed in 1939, neither used the gull-wing doors and it would be another eighty-odd years before Bugatti’s design was realised when collector & president of the American Bugatti Club, Peter Mullin (b 1941), arranged the fabrication of the coachwork, based on the original drawings.  Built in exactly the same way craftsmen would have accomplished the task in 1939, the body was mounted on the surviving Type 64 chassis (64002), united for the first time with what Jean Bugatti called papillon (butterfly) doors which all (except the French) now call gull-wings.

Mercedes-Benz and the gull-wing.

1952 Mercedes-Benz 300 SL prototype (W194).

By 1951, although the Wirtschaftswunder (the post-war German “economic miracle”) still lay ahead, structural changes (the most important being the retreat by the occupying forces in the western zones from the punitive model initially adopted and the subsequent creation in 1948 of the stable deutschmark), had already generated an economy of unexpected strength and Mercedes-Benz was ready to make a serious return to the circuits.  Because the rules then governing Formula One didn’t suit what it was at the time practical to achieve, the first foray was into sports car racing, the target the ambitious goal of winning the Le Mans 24 hour race, despite a tight budget which precluded the development of new engines or transmissions and dictated the use of as much already-in-production as possible.

1952 Mercedes-Benz 300 SL prototype (W194).

It was the use of a production car engine designed not for ultimate power but smoothness, reliability and a wide torque band which ultimately dictated the use of the gull-wing doors.  The engine was the 3.0 litre (183 cubic inch) M186 straight-six used in the big 300 limousines and its two door derivatives, of advanced design by the standards of the time but also big, tall and heavy, attributes not helpful to race-car designers who prefer components which are compact, light and able to be mounted low in a frame.  A new engine not being possible, the factory instead created a variation, the M194, which used the triple-carburetor induction of the 300S coupés in an improved cylinder head, the innovation being the iron-block now lying at a 50^o angle, thereby solving the problem of height by allowing it to be installed while canted to the side, permitting a lower bonnet line.  Using the existing gearbox, it was still a heavy engine-transmission combination, especially in relation to its modest power-output and such was the interest in lightness that, initially, the conventional wet-sump was retained so the additional weight of the more desirable dry-sump plumbing wouldn’t be added.  It was only later in the development-cycle that dry-sump lubrication was added.

1952 Mercedes-Benz 300 SL space-frame (W194).

The calculations made suggested that with the power available, the W194 would be competitive only if lightness and aerodynamics were optimized.  Although the relationship between low-drag and down-force were still not well-understood, despite the scientific brain-drain to the US and USSR (forced and otherwise) in the aftermath of the war, the Germans still had a considerable knowledge-base in aerodynamics and this was utilized to design a small, slippery shape into which the now slanted straight-six would be slotted.  There being neither the time nor the money to build the car as a monocoque, the engineers knew the frame had to be light.  A conventional chassis was out of the question because of the weight and they knew from the pre-war experience of the SSKL how expensive and difficult it was to reduce mass while retaining strength.  The solution was a space-frame, made from tubular aluminum it was light, weighing only between 50-70 kg (110-155 lb) in it’s various incarnations yet impressively stiff and the design offered the team to opportunity to use either closed or open bodies as race regulations required.

However, as with many forms of extreme engineering, there were compromises, the most obvious of which being that the strength and torsional rigidity was in part achieved by mounting the side tubes so high that the use of conventionally opening doors was precluded.  In a race car, that was of no concern and access to the cockpit in the early W194s was granted by what were essentially top-hinged windows which meant ingress and egress was not elegant and barely even possible for those of a certain girth but again, this was though hardly to matter in a race car.  In this form, the first prototypes were built, without even the truck-like access step low on the flanks which had been in the original plans.

1952 Mercedes-Benz 300 SL production coupé (W194).

Actually, it turned out having gull-wing windows instead of gull-wing doors did matter.  Although the rules of motorsport’s pettifogging regulatory body, the Fédération Internationale de l'Automobile (the FIA; the International Automobile Federation) were silent on the types and direction of opening doors and, in the pre-war era they had tolerated some essentially fake doors, their scrutineers still raised objections during inspection for the 1952 Mille Miglia.  The inspectors were forced to relent when unable to point to any rule actually being broken but it was clear they’d be out for revenge and the factory modified the frame to permit doors extending down the flanks, thereby assuming the final shape which would come to define the gull-wing door.  Relocating some of the aluminum tubing to preserve strength added a few kilograms but forestalled any retrospective FIA nit-picking.  To this day, the FIA's legions of bureaucrats seem not to realise why they’ve for so long been regarded as impediments to competition and innovation.

The W194 at Le Mans, 1952.

First tested on the Nürburgring and Hockenheimring in late 1951, the W194, now dubbed 300 SL for promotional purposes, was in March 1952 presented to the press on the Stuttgart to Heilbronn autobahn.  In those happy days, there was nothing strange about demonstrating race cars on public highways.  The SL stood for Super Leicht (super light), reflecting the priority the engineers had pursued.  Ten W194s were built for the 1952 season and success was immediate, second in the Mille Miglia; a trademark 1-2-3 result in the annual sports car race in Bern and, the crowning achievement, a 1-2 finish in the twenty-four hour classic at Le Mans.  Neither usually the most powerful nor the fastest car in the races it contested, the 300 SL nevertheless so often prevailed because of a combination of virtues.  Despite the heavy drive-train, it was light enough not to impose undue stress on tyres, brakes or mechanical components, the limousine engine was tough and durable and the outstanding aerodynamics returned surprising good fuel economy; in endurance racing, reliability and economy compensate for a lot of absent horsepower.

As a footnote (one to be noted only by the subset of word nerds who delight in the details of nomenclature), for decades, it was said by many (even normally reliable sources) that SL stood for Sports Leicht (sports light) and the history of the Mercedes-Benz alphabet soup was such that it could have gone either way (the SSKL (1929) was the Super Sports Kurz (short) Leicht (light)) and from the 1950s on, for the SL, even the factory variously used Sports Leicht and Super Leicht.  It was only in 2017 it published a 1952 paper (unearthed from the corporate archive) confirming the correct abbreviation is Super Leicht.  Sports Leicht Rennsport (Sport Light Racing) seems to be used for the the SLRs because they were built as pure race cars, the W198 and later SLs being road cars but there are references also to Super Leicht Rennsport.  By implication, that would suggest the original 300SL (the 1951 W194) should have been a Sport Leicht because it was built only for competition but given the relevant document dates from 1952, it must have been a reference to the W194 which is thus also a Sport Leicht.  Further to muddy the waters, in 1957 the factory prepared two lightweight cars based on the new 300 SL Roadster (1957-1963) for use in US road racing and these were (at the time) designated 300 SLS (Sports Leicht Sport), the occasional reference (in translation) as "Sports Light Special" not supported by any evidence.  The best quirk of the SLS tale however is the machine which inspired the model was a one-off race-car built by Californian coachbuilder ("body-man" in the vernacular of the West Coast hot rod community) Chuck Porter (1915-1982).  Porter's SLS was built on the space-fame of a wrecked 300 SL gullwing (purchased for a reputed US$500) and followed the lines of the 300 SLR roadsters as closely as the W198 frame (taller than that of the W196S) allowed.  Although it was never an "official" designation, Porter referred to his creation as SL-S, the appended "S" standing for "scrap". 

W194 roadsters at Nürburgring, 1952.

After the triumph at Le Mans, the SL won at the Eifelrennen and was then entered into in a race on the Nürburgring and to shed some weight, engineers converted three of the coupés to roadsters, emulating the body of one of the original ten which had been open-topped from the start.  To avoid any unpleasantness with the FIA, the section of the doors extending into the side of the car was retained and a smaller windscreen was installed to improve aerodynamics and afford the driver some protection from the weather and bugs unfortunate enough to be caught in the path.  The roofectomy reduced weight by about 100 kg (220 lb) which presumably helped, the four finishing in the first four places.

Winning W194, 1952 Carrera Panamericana Mexico, the protective metal struts were an ad-hoc addition after a bird strike.

One final adventure for the year yielded a perhaps unexpected success.  In November 1952, the factory entered two coupés and two roadsters in the third Carrera Panamericana Mexico, a race of 3100 kilometres (1925 miles) over five days and eight stages, their engines now bored out to 3.1 litres (189 cubic inches) increasing power from 175 bhp (130kw) to 180 (135).  The cars finished 1-2-3 although the third was disqualified for a rule violation and the winning car endured the intrusion at speed of a vulture through the windscreen.  Unlike the 300 SL, the unlucky bird didn’t survive.  There was however one final outing for the W194.  In 1955 it won the Rally Stella Alpina, the last time the event would be run in competitive form, one of many cancelled in the wake of the disaster at Le Mans that year in which 84 died and almost two-hundred injured.  Coincidently, that accident involved the W194’s successor, the 300 SLR.

1953 300 SL Prototype.

The 300 SL was re-engineered for the 1953 season, the bodywork now made from magnesium, lighter even than aluminum, the design of which had seen the car return to the wind-tunnel after which it gained a revised front section which not only reduced drag but also improved cooling by optimizing airflow to the radiator and engine compartment.  Power rose too.  Again drawing from wartime experience with the DB60x V12 aero-engine used in many German warplanes, direct fuel-injection was introduced which boosted output from 180 bhp (135 kw) to 215 bhp (158 kW).  Nor were the underpinnings neglected, the rear suspension design improved (somewhat) with the addition of the low-pivot single-joint swing axle (which would later appear on some production 300 SLs) while the transmission was flanged on the rear axle, not quite a transaxle but much improving the weight distribution.  The wheelbase was shortened by 100 millimetres (4 inches) and 16-inch wheels were adopted.  Even disk brakes were considered but the factory judged them years from being ready and it wouldn’t be until 1961 that they appeared on a Mercedes-Benz, more than half a decade after others had proved the technology on road and track.  There was however one exception to that, a disc brake had been installed between propeller shaft and differential on the high-speed truck built in 1954 to carry the Grand Prix cars between the factory and circuits in Europe.

The revised 300 SL however was never raced, the factory’s attention now turning to the Formula One campaign which, with the W196, would so successfully be conducted in 1954-1955, an off-shoot of which would be the W194’s replacement, the W196S sports car which would be based on the Grand Prix machine and dubbed, a bit opportunistically, the 300 SLR (Sport Leicht Rennen (Sport Light-Racing)).  Such was the impression made by the futuristic W194 that it would inspire production of the road-going 300 SL Gullwing (W198), 1400 of which were built during 1954-1957 (including 29 with aluminium bodies).

1955 Mercedes-Benz 300 SL (W194) (1954-1957).

Although the public found them glamorous, the engineers at Mercedes-Benz had never been enamoured by the 300 SL’s gull-wing doors, regarding them a necessary compromise imposed by the high side-structure of the space-frame which supported the body.  Never intended for use on road-cars, it was the guarantee of the US importer of Mercedes-Benz to underwrite the sale of a thousand gull-wing coupés that saw the 300 SL Gullwing enter production in 1954.  The sales predictions proved accurate and of the 1400 built, some 80% were delivered to North American buyers.  The W198 300SL was the model which became entrenched in the public imagination as “the Gullwing” and it’s the only instance where the word doesn’t need to be hyphenated.  Glamorous those doors may have been, they did impose compromises.  The side windows didn’t roll down, ventilation was marginal and air-conditioning didn’t exist; in a hot climate, one really had to want to drive a Gullwing.  There was also the safety issue, some drivers taking the precaution of carrying a hammer in case, in a roll-over, the inability to open the doors made the windscreen the only means of escape and roll-overs were perhaps more likely in a Gullwing than many other machines, the nature of the swing axles sometimes inducing unwanted behavior in what was one of the fastest cars on the road although, in fairness, on the tyres available in the 1950s that was less of an issue than it would become on later, stickier rubber.

In the US in 1956, a "fully optioned" Gullwing would have been invoiced at US$8894.00 and apart from the car itself, some of those options would proved a good investment, items like the knock-off wheels adding by the 2020s at least tens of thousands to the selling price and even the fitted luggage attracts a premium.  The options affecting the mechanical specification (notably the camshaft and choice of final drive ratio) had a significant influence on the character of the car, the former raising the rated horsepower from 220 to 240 and in its more powerful form the top speed would have been 140-155 mph (225-250 km/h) depending on the gearing.  Those serious about speed could opt for the "package" of the aluminum body with "full competition equipment" including the Rudge wheels and upgraded engine & suspension, supplied with two complete axles in a choice of gear ratios.  That package listed at US$9300.00 which in retrospective was another reasonable investment given the aluminum Gullwing from Rudi Klein's "junkyard collection" sold at auction in October 2024 for US$9,355,000.  Still, all things are relative and average annual income in the US in 1956 was about US$3600 and while it was possible to buy what would now be called a "house & land package" for around US$8000, the typical house sold for more than twice that.  The 300 SL would still have been a sound investment because although one would have incurred maintenance, running and storage costs over the decades, a well maintained 1956 aluminum Gullwing would now sell for well in excess of US$10 million while US$9600 placed in the S&P 500 index would by 2024 be worth less that three million.  There have been better investments than aluminum Gullwings but not many.   

Mercedes-Benz 300 SLR (W196S), Stirling Moss & Denis Jenkinson, Mille Miglia, Italy, 1955.

The 300 SLR (W196S) was a sports car, nine of which were built to contest the 1955 World Sportscar Championship.  Essentially the W196 Formula One car with the straight-eight engine enlarged from 2.5 to 3.0 litres (152 to 183 cubic inches), the roadster is most famous for the run in the 1955 Mille Miglia in Italy which was won over a distance of 992 miles (1597 km) with an average speed of almost 100 mph (160 km/h); nothing like that has since been achieved.  There's infamy too attached to the 300 SLR; one being involved in the catastrophic crash and fire at Le Mans in 1955.

1955 300 SLR (W196S “Uhlenhaut” coupé). 

Two of the 300 SLRs were built with coupé bodies, complete with gull-wing doors.  Intended to be used in the 1955 Carrera Panamericana Mexico, they were rendered instantly redundant when both race and the Mercedes-Benz racing programme was cancelled after the Le Mans disaster.  The head of the programme, Rudolf Uhlenhaut (1906-1989), added an external muffler to one of the coupés, registered it for road use (such things were once possible when the planet was a happier place) and used it for a while as his company car.  It was then the fastest road-car in the world, an English journalist recording a top speed of 183 mph (295 km/h) on a quiet stretch of autobahn but Herr Uhlenhaut paid a price for the only partially effective muffler, needing hearing aids later in life.  Two were built (rot (red) & blau (blue), the names based on their interior trim) and for decades they remained either in the factory museum or making an occasional ceremonial appearance at race meetings.  However, in a surprise announcement, in June 2022 it was revealed rot had been sold in a private auction in Stuttgart for a world-record US$142 million, the most expensive car ever sold.  The buyer's identity was not released but it's believed rot is destined for a collection in the Middle East.  It's rumoured also the same buyer has offered US$100 million should an authentic 1929 Mercedes-Benz SSKL ever be uncovered.  

1970 Mercedes-Benz C-111 (1968-1970 (Wankel versions)).

Although the C-111 would have a second career in the late 1970s in a series of 5-cylinder diesel and V8 petrol engined cars used to set long-distance endurance records, its best remembered in its original incarnation as the lurid-colored (safety-orange according to the factory) three and four-rotor Wankel-engined gullwing coupés, sixteen of which were built.  The original was a pure test-bed for the Wankel engine in which so many manufacturers once had so much hope.  The first built looked like a failed high-school project but the second and third versions were both finished to production-car standards with typically high-quality German workmanship.  Although from the school of functional brutalism rather than the lovely things they might have been had styling been out-sourced to the Italians, the gull-winged wedges attracted much attention and soon cheques were enclosed in letters mailed to Stuttgart asking for one.  The cheques were returned, apparently there had never been plans for production even had the Wankel experiment proved a success.  The C-111 was fast, the four-rotor version said to reach 300 km/h (188 mph), faster than any production vehicle then available.

1991 Mercedes-Benz C112.

The C112 was an experimental mid-engined concept car built in 1991.  Designed to be essentially a road-going version of the Sauber-built C11 Group C prototype race car developed for the 1990 World Sports-Prototype Championship, it was powered by the 6.0 litre (366 cubic-inch) M120 V12 used in the R129 SL and C140/W140 S-Class variously between 1991-2001.  The C112 does appear to have been what the factory always claimed it was: purely a test-bed for technologies such as the electronically-controlled spring & damper units (which would later be included on some models as ABC (active body control)), traction control, rear wheel steering, tyre-pressure monitoring and distance-sensing radar.  As an indication it wasn't any sort of prototype intended for production, it offered no luggage space but, like the C111 twenty years earlier, it’s said hundreds of orders were received.  It was 1991 however and with the world in the depths of a severe recession, not even that would have been enough for a flirtation with thoughts of a production model.  After the C112, thoughts of a gull-wing were put on ice for another two decades, the SLR-McLaren (2003-2009) using what were technically “butterfly” door, hinged from the A-pillars.

2011 Mercedes-Benz SLS-AMG (2101-2014).

The factory’s most recent outing of the gull-wing door, the SLS, which used the naturally aspirated 6.2 litre (379 cubic inch) M159 DOHC V8, was produced between (2010-2014), a roadster version also available.  To allay any doubt, it was announced at the time of release that SLS stands for Super Leicht Sport (Super Light Sport) although such things are relative, the SLS a hefty 1600-odd kg (3,500 lb) although, in fairness, the original Gullwing wasn’t that much lighter and the SLS does pack a lot more gear, including windows which can be opened and air-conditioning.  In the way of modern marketing, many special versions were made available during the SLS’s relatively short life, even an all-wheel-drive electric version with a motor for each wheel.  Such is the lure of the gull-wing motif for Mercedes-Benz, it’s unlikely the SLS will be the last and a high-priced revival is expected to become a feature of the marketing cycle every couple of decades but we're unlikely to see any more V8s or V12s unless perhaps as a swan-song, AMG indicating recently they expect their 4.0 litre (244 cubic inch) V8 to remain in production for another ten years, Greta Thunberg (b 2003) and her henchmen the humorless EU bureaucrats permitting.

Tesla Model X with falcon-wing doors.

Such was the allure of the 300 SL’s gull-wing doors that in the shadow they’ve cast for seventy-odd years, literally dozens of cars have appeared with the features, some of questionable aesthetic quality, some well-executed and while most were one-offs or produced only in small runs, there’s been the occasional (usually brief) success and of late some Teslas have been so equipped and with the novelty of them being the back doors, the front units conventionally hinged.  Tesla calls them “falcon wings” because the design was influenced by the bird.  However, the biomimicry was (for obvious reasons) not an attempt to gain the aerodynamic advantages of the falcon’s wing shape which affords exceptional maneuverability in flight but simply an adoption of the specific bone structure.  Unlike the fixed structure of the classic gull-wing door, the Tesla’s falcon-wing is fitted with an additional central joint which permits them to be opened in cramped spaces, aiding passenger ingress and egress.  Some Tesla engineers have however admitted the attraction of them as way to generate publicity and (hopefully) attract sales may have been considered during the design process.

Bricklin SV-1 (1974-1975, left) and DMC DeLorean (1981-1983, right).

Two of the best known of the doomed gull-wing cars were the Bricklin SV1 and the DeLorean, both the creations of individuals with interesting histories.  Malcolm Bricklin’s (b 1939) first flirtation with the automotive business was his introduction into the US market of the Subarus, built by the Japanese conglomerate Fuji Heavy Industries.  Having successfully imported the company’s scooters for some years, the model Mr Bricklin in 1968 chose was the 360, a tiny, egg-shaped device which had been sold in Japan for a decade, the rationale underlying his selection being it was so small and light it was exempt from just about any regulations.  Although really unsuited to US motoring conditions it was (at US$1300) several hundred dollars cheaper than a Volkswagen Beetle and had a fuel consumption around a third that delivered by the even the more economical US-built cars so it found a niche and some ten-thousand were sold before that gap in the market was saturated.  Ever imaginative, Mr Bricklin then took his hundreds of unsold 360s and re-purposed them essentially as large dodgem-cars, renting unused shopping-mall car-parks as ad-hoc race tracks and offering “laps” for as little as $US1.00.  He advertised “no speed limits” to attract the youth market but given the little machines took a reported 56 seconds for the 0-60 mph (0-100 km/h) run, reaching the legal limit in a car-park would have been a challenge.  Mr Bricklin achieved further success with Subaru’s more conventional (in a front wheel drive (FWD) context) 1000 and the corporation would later buy out his US interests for was thought to be a most lucrative transaction for both parties.

1969 Subaru 360 Deluxe.

His eponymous gull-winged creation was the SV-1 which, although nominally positioned as a “sports car” was marketed also as a “safety-vehicle” (hence the SV).  It certainly contained all of the safety features of the time and in that vein was offered mostly in lurid “high visibility” colors although the prototypes for an up-market “Chairman” version were displayed in more restrained black or white.  It was ahead of its time in one way, being fitted with neither ash-trays nor cigarette lighters, Mr Bricklin not approving of smoking and regarding the distractions of lighting-up while at the wheel a safety hazard.  Whether in stable conditions the car could have succeeded is speculative but the timing was extraordinarily unlucky.  The V8-powered car arrived on the market in 1974 shortly after the first oil shock saw a spike in the price of gasoline and in the midst of the recession and inflation which followed in the wake of that.  Between its introduction and demise, the costs of the SV1 more than doubled and there were disruptions to the production process because supply problems (or unpaid bills depending on who was asked) meant the AMC engine had to be replaced with a Ford power-plant.  By the time production ended, some 3000 had been built, but, not discouraged, Mr Bricklin would go on to import Fiat sports cars and the infamous Yugo before being involved with a variety of co-ventures with Chinese partners.

1970 Pontiac GTO convertible.

John DeLorean (1925–2005) was a genuinely gifted engineer who emerged as one of the charismatic characters responsible for some of the memorable machines General Motors (GM) produced during its golden age of the 1950s & 1960s.  Under Mr DeLorean’s leadership, Pontiac in 1964 released the GTO which is considered (though contested by some) the first “muscle car” and the one responsible for the whole genre which would flourish for a crazy half-dozen years and in 1969 the Grand Prix which defined a whole market segment.  Apparently, the Grand Prix, produced at a low cost and sold at a high price was one of the most profitable lines of the era.  Given this, Mr DeLorean expected a smooth path to the top of GM but for a variety of reasons there were internal tensions and in 1973 he resigned to pursue his dream of making his own car.  It took years however to reach fruition because the 1970s were troubled times and like the Bricklin SV1, the DeLorean Motor Company’s (DMC) gull-winged DeLorean was released into a world less welcoming then had been anticipated.  By 1981, the world was again in recession and the complicated web of financing arrangements and agreements with the UK government to subsidize productions could have worked only if the design was good, demand was strong and the product was well-built, none of which was true.

1969 Pontiac Grand Prix 428 SJ.

As the inventory of unsold cars grew, so did the debt and desperate for cash, Mr DeLorean was persuaded (apparently without great difficulty) to become involved in the cocaine trafficking business which certainly offered fast money but his co-conspirator turned out to be an FBI informant who was a career criminal seeking a reduced sentence (on a unrelated matter) by providing the bureau with “a big scalp”.  At trial in 1984, Mr DeLorean was acquitted on all charges under the rule of "entrapment" but by then DMC was long bankrupt.  In the years since, the car has found a cult following, something due more to its part in the Back to the Future films than any dynamic qualities it possessed.  It was competent as a road car despite the rear-engine configuration and the use of an uninspiring power-plant but, apart from the stainless-steel bodywork and of course the doors, it had little to commend it although over the years there have been a number of (ultimately aborted) revivals and plans remain afoot for an electric gull-wing machine using the name to be released in 2024 or 2025.
