Slant

Slant (pronounced slant or slahnt)

(1) A surface, structure, line etc at a slope or in an oblique direction.

(2) In (US) football, an offensive play in which the ball-carrier runs toward the line of scrimmage at an angle (known also as the “slant-in”, a pass pattern in which a receiver cuts diagonally across the middle of the field).

(3) In prosody, as “slant rhyme”, a synonym for the “half rhyme”, “near rhyme” & “quasi-rhyme” (a form of imperfect rhyme in which the final (coda) consonants of stressed syllables (and, in modern English poetry, any following syllables to the end of the words) are identical in sound, but the vowels of the stressed syllables are not.

(4) In typography, a synonym of slash ( / ⟩, particularly in its use to set off pronunciations from other text (not used in IT where the distinctions are between the forward-slash (/) and the back-slash (\) which nerds call respectively the slash and the slosh.

(5) In biology, a sloping surface in a culture medium.

(6) In hydro-carbon extraction, as “slant drilling”, a technique in which the drilling is undertaken at an oblique angle rather than the traditional vertical orientation.

(7) In extractive mining, as type of run in which a heading is driven diagonally between the dip and strike of a coal seam.

(8) In informal use, a glance or look.

(9) To veer or angle away from a given level or line, especially from a horizontal; slope (in to incline, to lean).

(10) Figuratively, to have or be influenced by a subjective point of view, bias, personal feeling or inclination etc (often as “slant towards”, “slanted view” etc); a mental leaning, bias, or distortion (“feminist slant”, “MAGA slant”, “liberal slant”, “business slant” et al).

(11) To cause to slope.

(12) Figuratively, to distort information by rendering it unfaithfully or incompletely, especially in order to reflect a particular viewpoint (more generously sometimes described as “spin” or “massaged”).  The concept is known also as “angle journalism” (the particular mood or vein in which something is written, edited, or published).  In Scots English, the meaning “to lie or exaggerate” captures the flavor.  When used to describe the composing, editing, or publishing of something to attract the interest of a specific sub-group (a “slanted” story), “slanted towards” is necessarily pejorative if used only to suggest something optimized to appeal to a certain market segment or demographic (ie it’s more like “aimed at” or “intended for”).

(13) In slang, as “slant eye” (a racial slur now listed as disparaging & offensive), a reference to people from the Far East (applied historically mostly to the Chinese & Japanese), based on the shape of the eyes.  The variants included “slit eye”, “slitty-eyed” & “slopehead”, all equally offensive and now proscribed.

(14) In painting (art) a pan with a sloped bottom used for holding paintbrushes; a depression on a palette with a sloping bottom for holding and mixing watercolors; a palette or similar container with slants or sloping depressions.

(15) In US regional slang, a sarcastic remark; shade, an indirect mocking insult (archaic).

(16) In US slang, an opportunity, particularly to go somewhere (now rare).

(17) In historic Australian colonial slang, a crime committed for the purpose of being apprehended and transported to a major settlement.

Circa 1480s: From the Middle English –slonte or -slonte, both aphetic (in phonetics, linguistics & prosody, “of, relating to, or formed by aphesis” (the loss of the initial unstressed vowel of a word)) variants of aslant, thought to be of Scandinavian origin.  The other influence was probably the earlier dialectical slent, from the Old Norse or another North Germanic source and cognate with the Old Norse slent, the Swedish slinta (to slip) and the Norwegian slenta (to fall on the side), from the Proto-Germanic slintaną (which, in turn, was probably in some way linked with aslant.  Slant & slanting are nouns, verbs & adjectives, slanted is a verb & adjective, slantish is an adjective, slantwise is an adjective & adverb and slantingly & slantly are adverbs; the noun plural is slants.  The pleasing adjective slantendicular is listed by some as non-standard and presumably is proscribed in geometry and mathematics because it's an oxymoron; it’s a portmanteau word, the construct being slant + (perp)endicular.  It may be useful however in commerce or engineering where it might be used to describe something like a tool with a shaft which at some point assumes an oblique or skewed angle.   So it’s there to be used and slantindicular should be applied to stuff which is neither wholly nor fully slanted and in architecture, such structures are numerous.  In commerce, it could be used as a noun.

The noun slant by the 1650s was used to mean “an oblique direction or plane” and began in geography & civil engineering (of landforms, notably ski-slopes), developed from the verb or its adjective.  The now familiar (in the Fox News sense) meaning “way of regarding something, a mental bias” dates from 1905 while the derogatory slang sense of “a person of Asian appearance” came into use some time in the 1940s, a direct descendent from the earlier "slant-eyes", documented since 1929.  The verb slant is documented since the 1520s in the sense of “obliquely to strike (against something)”, an alteration the late thirteenth century slenten (slip sideways), the origin of which is murky but etymologists have concluded it came (via a Scandinavian source (noting the Swedish slinta (to slip)) and the Norwegian slenta (to fall on one side), from the Proto-Germanic slintanan.  The intransitive sense of “to slope, to lie obliquely” was in use by the 1690s, while the transitive sense of “to give a sloping direction to” had emerged by the early nineteenth century.  As early as the late fifteenth century forms were in use as an adverb, the adjectival use attested from the 1610s.  The technical use in literary theory as “poetic slant rhyme” was first used in the mid 1920s (assonance or consonance) although such lines had appeared for centuries, used sometimes deliberately as a device, sometimes not.  In the following stanza by English poet Peter Redgrove (The Archaeologist, published in Dr Faust's Sea-Spiral Spirit (1972)), the second and third lines contain a form of slant rhyme while the first and fourth have pure rhymes:

So I take one of those thin plates
And fit it to a knuckled other,
Carefully, for it trembles on the edge of powder,
Restore the jaw and find the fangs their mates.

You are watching Fox.

While it’s unlikely volumes of the poetry of Emily Dickinson (1830–1886) sit upon the bookshelves of those members of the Fox News audience who have bookshelves, they likely would concur with her words: “Tell the truth but tell it slant.”  “Slanted reporting” has become something which in recent years has attracted much attention (and much hand-wringing by the usual suspects) as an increasingly polarization of positions has been alleged to be a feature of political discourse in the West.  There is little doubt the effect (as reported) is obvious but there’s some debate about both the mechanics and the implications of the phenomenon.  As long ago as 2018, a study found that although the tenor and volume of things on X (formerly known as Twitter) was found to be increasingly toxic and surging, the number of active users engaged in these political polemics was found to be tiny and their effect was distorted by (1) the huge number of tweets they tended to post, (2) the propensity of their fellow-travelers to re-tweet and (3) the use of bots which were more prolific still.  If anything, recent voting patterns suggest it would seem the views of the general population appear to be trending away from the extremes towards the more centralist positions offered by independents or small-parties, something most obvious in Australia where compulsory voting exists.  Outfits like Fox News offer a slanted take on just about everything (and promote country & western music which truly is inexcusable) but this is something which has been identifiable in the news media as long as it’s existed and their blatant bias is hardly subversive or threatening, simply because it is so blatant.  What was most interesting in what emerged from the recent defamation suit filed by Dominion Voting Systems against Fox News suggested the network’s stance on things was motivated more by the financial imperative than ideological purity.  Intriguingly, what some analysts concluded was that if the universe shifted and the Fox News audience transformed into a bunch of seed-eating hippies, there would follow Fox’s editorial position, the slant being towards the advertising revenue rather than a particular world view.  Of course, there are some slants which are unalterable and dictated by ideological purity but with commercial media, it’s likely sometimes cause is confused with effect.

The Leaning Tower of Pisa (left) and Lindsay Lohan in The Parent Trap (1998) in front of London’s perpendicular Big Ben (1859) (right).  The architect’s original name for the latter was a typically succinct “Clock Tower”, chosen because it housed the “Great Bell of the Great Clock of Westminster” but it was in 2012 renamed “Elizabeth Tower”, marking the Diamond Jubilee of Elizabeth II (1926-2022; Queen of the UK and other places, 1952-2022), something little noted by Londoners or those beyond who continue to prefer the nickname “Big Ben” although strictly speaking that’s a reference only to the “Great Bell” a 13.5 ton (13.7 tonne) casting in bell metal (a bronze which is an alloy of about 77% copper & 23% tin).  The origin of the nickname is contested but there are no romantic tales, all the possible inspirations being worthy white men as was the Victorian way.

Although in Italy alone there are seven leaning towers (three of which stand (ie lean) in Venice), it’s the torre di Pisa (Tower of Pisa) which is by far the best-known and a frequent Instagram prop.  Built between 1173-1372, the structure in the Piazza del Duomo (Pisa’s Cathedral Square) is the campanile (the freestanding bell tower) of the adjacent Pisa Cathedral and the famous lean of some 4^o (actually somewhat less than its greatest extent after more than a century of compensating engineering works) was apparent even during construction, the cause the softness of the sub-surface.  That geological feature has however contributed to the tower’s survival, the “rubber-like” sponginess below acting to absorb movement and despite a number of severe earthquakes in the region over the centuries, the tower remains.  It is of course known as the leaning tower than a sloping, oblique or slanted tower, probably because of the conventions of use which evolved in English.

The words “sloping”, “oblique”, “slanted”, & “leaning” all describe something not vertical or horizontal there tend to be nuances which dictate the choice of which to use.  Sloping generally is used of something which inclines or declines at a gentle or continuous angle, the implication being of a gradual or smooth transition from elevation to another, such as the way a hillside rises gradually rises to its summit.  Oblique is mostly a matter of specific angles and is thus common is mathematics, geometry and engineering.  Again, it’s a reference to something neither parallel nor perpendicular to a baseline but it tends to be restricted to something which can be defined with an exact measurement; in geometric or technical use, an oblique line or angle is one neither 90^o nor perfectly horizontal.  Slanted describes something positioned at a diagonal, often used to imply a more noticeable or sharp angle but also is widely used figuratively, metaphorically and in idiomatic phrases.  Leaning refers to something tilted or positioned at an angle due to external pressure, the object in an unstable position and in need of support.  The implication carried is that something which “slants” is designed thus to do while something which “leans” does so because of some design flaw or unexpected external force being applied so it’s the leaning and not the sloping tower of Pisa, even though the structure has assumed quite a slope.

Slanting Engines

On a slant: Diagram of the mounting of the M194 straight-six engine in the Le Mans winning Mercedes-Benz 300 SL (W194) canted at a 40^o slant (left); the Mercedes-Benz M196 straight-eight engine schematic (centre) and installed in a 1954 W196R "Streamliner" at a 53^o slant (right).  The two large donut-like objects at the front are the inboard, finned brake drums; at the time, the engineers maintained disk brakes were "not yet ready for use". 

There are “slant” engines and they exist in three configurations.  The first is simply a conventional in-line engine (straight-six, straight-eight etc) which, when installed in a vehicle, is fitted with the block canted to the left or right, the objective being a lower hood line which means a better aerodynamic outcome.  A classic example was the Mercedes-Benz W196R Formula One racing car (1954-1955) in which the straight-eight was canted to the right at a 53^o angle, the technique carried over when the same structure was used to produce the W196S (1955) used to contest the World Sports Car Championship.  Rather opportunistically, the W196S was dubbed the 300 SLR (one of which in 2022 became the world's most expensive used car, selling at a private auction for US$142 million) as a form of cross promotion with the 300 SL (W198, 1954-1956) Gullwing then in production, even though the two types shared little more than nuts, bolts and a resemblance.  The 300 SL did however also have its straight-six engine sitting at a slant, this time canted at a 50^o angle and although the factory never published an estimate of the reduction in drag, it’s long been presumed to be “at least several percent”.  Another advantage of the configuration was it made possible the use of “long-tube” runners for the induction system, taking advantage of the properties of fluid dynamics to permit them to be tuned either for mid-range torque or top-end power.  The concept used math which had been worked out in the nineteenth century and had often been used in competition but it wasn’t until 1959 when Chrysler in the US released their picturesque induction castings that the system, imaginatively named the “Sonoramic”, reached a wider audience.

Chrysler Slant Six (170 cid, 1963) schematic.

The “true” slant engines were those with a slanted block atop an otherwise conventional arrangement of components, the best known of which was Chrysler’s long-serving “Slant Six”, produced in displacements of 170 cubic inch (2.8 litre, 1959-1969), 198 cubic inch (3.2 litre, 1970-1974) and 225 cubic inch (3.7 litre, 1960-2000).  The block of the Slant Six was canted to the right at a 30^o and like Mercedes-Benz, Chrysler took advantage of the space created to the left to produce some wide induction runners, the most extravagant those used by the special Hyper Pack option package which used a four barrel carburetor, enabling the engine to produce power which made it competitive with many V8 powered machines.  Although the name “Slant Six” became famous, it was only in the mid-sixties it caught on, Plymouth originally calling the thing a 30-D (a reference to the a 30^o slant), hardly very catchy and something to which only engineers would relate and Slant Six was soon preferred although the aficionados really like “tower of power” and the engine even today still has a devoted following.

Chrysler didn’t restrict the Sonoramics to the big-block V8s, using it also on the short-lived (1960-1962) Hyper Pak performance option for the both 170 cubic inch (2.8 litre, 1959-1969) and 225 cubic inch (3.7 litre, 1987-2000) versions of the Slant Six, the engineers taking advantage of the space afforded by the canted block to permit the curvaceous intake runners nearly to fill the engine bay.  The Hyper Pak wasn't seen in showrooms but was available as an over-the-counter kit (literally a cardboard box containing all necessary parts) from Dodge & Plymouth spare parts departments and its life was limited because it became a victim of its own success.  Although less suitable for street use because it turned the mild-mannered straight-six into something at its best at full throttle, in the race events for which it was eligible it proved unbeatable, dominating the competition for two years, compelling the sanctioning body cancel the series.

Manifold porn: The Slant Six's angle meant there was much space available to the left and a range of intake manifolds followed, some of which remain available to this day.  Using variations of the sonoramic tuning, manifolds were produced for single, two & four barrel carburetors and between 1965-1968, Chrysler's Argentine operation produced the Slant Six in a version with twin single barrel carburetors.  The use of the properties of fluid dynamics to gain power or torque as desired quickly was adopted by the industry as an engineering orthodoxy.

Some myths seem to have become attached to the Hyper-Pak.  What seems to be true is the original kit, sold in 1960 for the 170 engines used in competition, was a genuine homologation exercise and as well as the intake manifold & Carter AFB four barrel carburetor, it included all the internal parts such as the high-compression pistons, the high-lift camshaft and the valve train components needed to support the consequently higher engine speeds.  Because the competition rules allowed modifications to the exhaust system, on the track the cars ran tubular steel headers which fed an open exhaust, terminating in the racers' preferred “dump pipe”.  After the requisite number of “complete” kits were sold, thus fulfilling the homologation demands, the kits were reconfigured and included only the “bolt-on” parts such as the induction system and a camshaft which, while more aggressive than the standard unit, wasn’t as radical as the one used on the track but could be used in conjunction with the standard valve train and Chrysler’s TorqueFlite automatic, thus expanding the Hyper-Pak’s appeal.

At the same time, the availability was extended to the larger 225 which between 1961-1963 was also available with an aluminum block, thus becoming one of the small number of engines configured with the combination of an aluminum block with a cast-iron head.  US manufacturers were at the time aware the trend was for cars to continue getting bigger so they were interested in ways to reduce weight.  However, despite saving some 70 lbs (32 KG), Chrysler’s aluminum block was, like General Motors’ (GM) 215 cubic inch (3.5 litre) V8, short-lived (though the V8 after being sold to Rover enjoyed a long, lucrative and prolific second life, not finally laid to rest until 2006) for not only were teething troubles encountered with the still novel method of construction, the accountants made clear using cast iron was always going to be cheaper so the industry just accepted weight gain and whenever required, increased displacement to compensate, an approach which persisted until the first oil shock of the early 1970s.

1970 Dodge Challenger (1970-1974) with 225 Slant Six.

Until 1973, both the Challenger & the corporation's companion pony car (the Plymouth Barracuda (1964-1974)) was available with the Slant Six (198 & 225) although the fitment rate was under 10%, unlike the early pony cars (Ford Mustang, Chevrolet Camaro and the early Barracudas) where the six-cylinder versions would at times be close to 40% of production.  Many of the surviving Slant Six Challengers & Barracudas have been "re-purposed" as clones of the more desirable versions with big-block V8s.

Although it was the longer lived 225 version which gained the Slant Six its stellar reputation for durability and the ease with which additional power could be extracted, there's always been a following for the short-stroke 170 because of its European-like willingness to rev, the characteristics of the over-square engine (unique among the slant-six's three displacements (170-198-225)) unusually lively for a US straight-six.  Despite some aspects of the specification being modest (there were only four main bearings although they were the beefy units used in the 426 cubic inch Street Hemi V8), for much of its life it used a tough forged steel crankshaft and high-speed tolerant solid valve lifters; it proved a was a famously robust engine and one remarkably tolerant of neglect.  Despite that, after the Hyper Pak affair, Chrysler in the US showed little interest in any performance potential, knowing the US preference for V8s, something which doomed also Pontiac's short-lived single overhead camshaft (SOHC) straight-six (1966-1969).  A version of the 225 with a two-barrel carburetor (rated at 160 horsepower, an increase of 15 over the standard unit) was offered in some non-North American markets where V8 sales were not dominant and it proved very popular in South Africa, Australia, New Zealand and Central & South America but only when tighter US emission regulations forced its adoption did a 225 with a two barrel carburetor appear in the home market though there it was installed to restore the power losses suffered after the emission control plumbing was added rather than seek gains.

Making a straight-eight or V8 by combining two in-line fours has been done a few times and many have been successful (although Triumph managed to create a truly horrid one for the otherwise lovely Stag).  Less common is making a four from an eight but that’s what Pontiac did when they conjured their 194.5 cubic inch (3.2 litre) four by using one bank of their 389 cubic inch (6.4 litre) Trophy V8 and it was (just about) literally cut in half, meaning the cylinders were canted to the right by 45^o (the V8 obviously in a conventional 90^o configuration.  To emphasize the family connection with the highly regarded Pontiac Trophy V8, the smaller offspring was called the Trophy 4 (although it was at time also dubbed the Indy 4 or Indianapolis 4 which even at the time sounded ambitious).  It did work and the economic advantages for the manufacturer (use of common components and the same assembly line) were compelling but the limitations inherent in a four-cylinder of such a large displacement were apparent in the rough-running and wear on critical parts and it was available only between 1961-1963, only in the compact Tempest.

Diagram showing balance shaft locations.

Large displacement four cylinder engines have been built.  Fiat in 1910 built two of their S76s to contest the world LSR (land speed record) and they were an hefty 28.4 litres (1730 cubic inch), the “Beast of Turin” using its then impressive 290 horsepower (216 kW) to attain a one-way speed of 132.27 mph (213 km/h) but, because it was not possible for the team to make the “return run” (ie in the opposite direction) within the stipulated one hour, the LSR remained with the Blitzen Benz which in 1909 had set a mark of 125.94 mph (202.65 km/h).  On land, never again would anyone build a four with the capacity to match the Beasts of Turin but units with displacements approaching 5.0 litres (305 cubic inch) were not uncommon during the inter-war years.  However, the technology of the internal combustion engine (ICE) greatly advanced during World War II (1939-1945) and one consequence of that was engine speeds rose and less displacement was required for a specific output, both factors which conspired to make the big fours unfashionable.  They did however make a comeback in the 1970s when the clever trick of “balance shafts” enabled the inherently chronic second order harmonic vibrations to be “dampened out” and Porsche between 1991-1995 produced a 3.0 litre (183 cubic inch) range which used the technique.  The balance shaft was invented early in the twentieth century by English engineer Frederick Lanchester (1868–1946) but it was Mitsubishi which in the 1970s patented their “Silent Shaft” system and although Porsche developed their own version, they worked out the Japanese design was superior so used that instead, paying Mitsubishi a small royalty (under US$10) for each one installed.  A balance shaft uses two counterweights (looking something like small hockey pucks with the shaft running through them), set some 1½ inches (40 mm) apart and turns at twice the engine-speed.  With one shaft mounted high on one side of the engine and the other low on the opposite side, the pair counter-rotates, balancing the large reciprocating mass.  

Kammback

Kammback (pronounced cam-bak)

A motif in automotive styling (originally dictated by wind tunnel findings during research into aerodynamic properties) in which rear of the car slopes downwards before being abruptly cut off to terminate in a vertical or near-vertical surface.  The things are known also as the Kamm tail (K-tail).

1950s (the actual design first appearing in 1938): The construct was Kamm + back.  The surname Kamm (related to Kamp) was of Germanic or Jewish (Ashkenazic) origin and translates literally from the German as “comb”.  The German comb was from the Middle High German kamb, kambe, kam & kamme and the Yiddish kam (comb).  Genealogists conclude Kamm was probably an metonymic occupational surname for someone who either made or sold combs, a common tool used for grooming or for textile work such as carding or combing wool.  There’s also the possibility the name of some Kamm clans could have been of topographic origin because in German, Kamm can also mean “ridge” or “crest” of a hill, mountain or some other elevation; it could thus have referred to someone who lived near such a geographical feature.  Less likely is that some arose from nicknames based on physical features or personal characteristics with Kamm used to describe someone with hair resembling a comb or someone with a sharp or distinctive personality.  The surname emerged in the Middle Ages, a time when hereditary family names were becoming more common in German-speaking regions and in addition to the presence in Germany, exists at various scale in areas with a historic patter of German migration (notably the north-eastern US and South Australia.

Back was from the Middle English bak, from the Old English bæc, from the Proto-West Germanic bak, from the Proto-Germanic bakam & baką which may be related to the primitive Indo-European beg- (to bend).  In other European languages there was also the Middle Low German bak (back), from the Old Saxon bak, the West Frisian bekling (chair back), the Old High German bah and the Swedish and Norwegian bak; there are no documented connections outside the Germanic and in other modern Germanic languages the cognates mostly have been ousted in this sense by words akin to Modern English ridge such as Danish ryg and the German Rücken.  At one time, many Indo-European languages may have distinguished the horizontal back of an animal or geographic formation such as a mountain range from the upright back of a human while in some cases a modern word for "back" may come from a word related to “spine” such as the Italian schiena or Russian spina or “shoulder”, the examples including the Spanish espalda & Polish plecy.

Tail was from the Middle English tail, tayl & teil (hindmost part of an animal), from the Old English tægl & tægel (tail), from the Proto-Germanic taglaz & taglą (hair, fibre; hair of a tail) (source also of the Old High German zagal, the German Zagel (tail), the dialectal German Zagel (penis), the Old Norse tagl (horse's tail) and the Gothic tagl (hair), from the primitive Indo-European doklos, from a suffixed form of the roots dok & dek- (something long and thin (referring to such things as fringe, lock of hair, horsetail & to tear, fray, shred)), source also of the Old Irish dual (lock of hair) and the Sanskrit dasah (fringe, wick).  It was cognate with the Scots tail (tail), the Dutch teil (tail, haulm, blade), the Low German Tagel (twisted scourge, whip of thongs and ropes; end of a rope), the dialectal Danish tavl (hair of the tail), the Swedish tagel (hair of the tail, horsehair), the Norwegian tagl (tail), the Icelandic tagl (tail, horsetail, ponytail), and the Gothic tagl (hair). In some senses, development appears to have been by a generalization of the usual opposition between head and tail.  The Oxford English Dictionary (OED) suggest the primary sense, at least among the Germanic tongues, seems to have been "hairy tail," or just "tuft of hair," but already in Old English the word was applied to the hairless "tails" of worms, bees etc.  The alternative suggestion is that the notion common to all is that of the "long, slender shape."  It served as an adjective from the 1670s.  A long obsolete Old English word for tail was steort.  Kammback is a noun; the noun plural is kammbacks.  No lexicographer seems to have listed Kammbackesque, Kammbacklike or Kammbackish as standard adjectives but, given the extent of the deviances from Professor Kamm's original which are still labelled as “Kammbacks”, they might be useful forms.  Who wouldn't want to be able to use terms like the comparative “more Kammbackish” and the superlative “most Kammbackish”?

Some notable Kammbacks

The Kammback (also known as the Kamm tail) was named after German engineer & aerodynamicist Professor Wunibald Kamm (1893–1966) who during the 1930s pioneered the shape, his work assisted greatly by some chicanery within the Nazi military-industrial complex which enabled the FKFA (Forschungsinstituts für Kraftfahrwesen und Fahrzeugmotoren Stuttgart (Research Institute of Automotive Engineering and Vehicle Engines Stuttgart) institute he established in 1930s to secure funding to construct a full-sized wind tunnel equipped with a two-part steel treadmill in the floor and an 8.8 metre (350 inch) diameter axial fan, able to drive air at up to 400 km/h (250 mph).  What the two concentric floor turntables allowed was that as well as enabling turbulence to be studied from the side on the running steel belt, slip angles were also possible.   At the time, it was the most modern structure of its kind on the planet, the very existence of which was owed to the priority afforded by the Nazis to re-armament, especially the development of modern airframes, most of the money eventually coming from the Reichs-Luftfahrt-Ministerium (RLM, the State Air Ministry).

A classic Kammback on a 1970 Fiat 850 Coupé (1965-1973), one of the last of the generation of post-war mainstream rear-engined cars built in Western Europe.

While Professor’s Kamm’s work on automobile shapes continued, increasingly the facility became focused on military contracts, contributing to an extraordinary range of novel aircraft designs, some revolutionary and most of which would never reach production.  All of this ceased in July 1944 when the facility was severely damaged in air-raids by Royal Air Force (RAF) Bomber Command, a costly campaign in which one mission incurred a loss-ration of 20% and it wasn’t until the late 1940s that reconstruction began after it was acquired by Daimler-Benz AG which enlarged and modernized the machinery, the early fruits including the 300 SL (the W194, first gullwing coupé) which won the 1952 Le Mans 24 hour race and the W196R “streamliner” Grand Prix race cars which created such a sensation in 1954.  Although he wasn’t part of “Operation Paperclip” (the US project which secured (by various means including the military “smuggling” them into the country despite many being wanted by those investigating war crimes and crimes against humanity) Professor Kann was acknowledged as one of the world’s leading authorities on turbulence and between 1947-1953 was part of the team working at Wright-Patterson Air Force Base in Dayton, Ohio.  Some of what was undertaken then remains classified but it can be assumed it was all related to military projects and what would later become the space program.

The Kammback which really wasn't: 1976 Chevrolet Vega Kammback.

One often misunderstood aspect of the Kamm tail is that the aerodynamic benefits are realized only if the flat, vertical surface created was no more than about 50% of the total area of the vehicle (as viewed directly from the back).  That’s why even designs which don’t conform to the requirements are often casually referred to as “Kammbacks” and in the US, Chevrolet were cynically opportunistic when the Vega range (1970-1977) included what was nothing more than a two-door station wagon (estate), it was named “Vega Kammback”.  Actually, even the existence of the thing in the US was unusual because at that stage, General Motors (GM) really “didn’t like” small station wagons but many critics did agree the Kammback was the best looking of the Vega’s body-styles.

The knowledge gained from aero-engine development during World War I (1914-1918) meant even the mainstream engines of the 1920s were developing much more power so the speeds of cars were rising.  Some intrepid types also took advantage of the number of huge, powerful aero-engines being sold cheaply as “war surplus”, installing them is powerboats and racing cars, resulting in some fast machines and not a few fatalities.  However, it became clear the law of diminishing returns applied as speeds rose because while an increase of 100 horsepower might make possible an increase in top speed from 100 to 120 mph, another 100 hp might yield only another 10 mph; wind resistance increasing too much for the power to overcome.  Thus the interest in aerodynamics, then usually called “streamlining” something which, coincidently, produced some memorable art deco designs buy the engineers were interested in higher speeds and lower fuel consumption for a given quantum of energy input (fuel consumption).

The AC Shelby Cobra (1962-1967) was small, light and powerful which made it an instant success on the race tracks but, ruggedly handsome though it was, its aerodynamics limited the top speed and on the some fast, open European circuits it gave away as much as 50 km/h (30 mph) to less powerful but more streamlined machines.  More power wasn’t the solution but a new Kammback body was and the Daytona duly won its class in the 1965 World Sports Car Championship.  All used the 289 cubic in (4.7 litre) Ford Windsor V8 although one briefly was fitted with a 390 (6.5) FE V8 and the planned 427 (7.0) version (CSX3027, the so-called “Daytona Super Coupe”) was never completed until sold by Shelby some 17 years later in a “rummage sale”.  The Kammback Daytona was the work of US designer Pete Brock (b 1936) and in a macabre coincidence, his namesake, the Australian racing driver Peter Brock (1945–2006) was killed while competing (in retirement) in a replica Daytona Coupe during the now defunct Targa West (2005-2021) in Western Australia.

Before the Kammback, the state of the aerodynamic art was the airship-like "streamliner" which, although it probably didn't cross the engineers' minds, owed something to the train of a bride's gown.  1939 Lincoln Zephyr V12 Coupe (left) and 1937 Mercedes-Benz 540K (W29) Special Roadster (originally delivered to Mohammad Zahir Shah (1914–2007; the last King of Afghanistan 1933-1973) (right).

What soon became clear was that the shape of the dirigible (better known as the “airship” or “blimp”) was close to ideal and needed to be tweaked only by honing it into a “teardrop shape” with a rounded nose, extending to a long, tapered tail, a shape which in the 1930s caught the imagination of designers who rendered some memorable designs although the most famous were impractical and inefficient in terms of packaging, thus suitable only for the then small market niche which sought speed.  It was to try to gain the benefits of streamlining in a shape more suitable for mass production that Professor Kamm and others took their slide-rules to the wind tunnel began to experiment.  The solution which emerged was to terminate the lovely, long flowing roofline with an abrupt end at a surface which was either vertical or close to it, an unexpected benefit being an improvement in high-speed stability, obviating the need for (a usually central) stabilizing fin (a la an aircraft’s tail).  By 1938, BMW had produced a car with a Kammback and although World War II (1938-1945) interrupted development by the late 1940s the shape had begun to appear in showrooms and in little more than ten years it was common in specially bodied racing cars.  That didn’t mean the allure of the teardrop went away because the aerodynamicists (who now had both access to bigger wind tunnels in which higher speeds could be tested and the novelty of computers which could process previously unimaginable quantities of data) could still prove ultimate slipperiness could be attained only with the teardrop.

It was this which convinced Porsche to use such a tail on their revolutionary 917 in 1969 and having encountered no stability issues on their test track, sent the car to the circuits where it proved as fast as expected.  Unfortunately, the size of the Porsche test facility limited the 917 to 290 km/h (180 mph) and when on the long straights of some European circuits when speeds exceeded 320 km/h, it was clear the thing was lethally unstable.  Although the drivers killed at the wheel of the early 917s didn’t die at such velocities, it was understood it would be only a matter of time so the rear bodywork was redesigned.  When in 2018 McLaren returned to the teardrop for the “Speedtail” (a car which sacrificed just about anything not mandated by law in the quest for top speed), it was able to achieve a safe (it’s a relative term) 400 km/h (250 mph) because advances in aerodynamics, computing, materials & hydraulics had made such things possible although the packaging inefficiencies remained, something not significant for the target market.

Junk

Junk (pronounced juhngk)

(1) In historic nautical use, old cable or cordage used when untwisted for making gaskets, maps, swabs etc and (when picked apart), the oakum used for filling the seams of wooden ships.

(2) A fragment of any solid substance; a thick piece; a chunk (obsolete).

(3) Old, damaged or discarded material (metal, paper, rags et al).

(4) Anything regarded as worthless, meaningless, or contemptible; nonsense; gibberish.

(5) Anything judged cheap or trashy.

(6) In slang, the narcotic heroin (used casually of other injected drugs, the users thus “junkies”).

(7) In historic sailor’s slang, as saltjunk, the salted beef or pork used as rations on long voyages, the origin being the comparisons in taste and texture made with junk (frayed old rope).

(8) In slang, the external genitalia (especially of a male if used as a target in unarmed combat).

(9) In baseball slang, relatively slow, unorthodox pitches, deceptive to the batter in movement or pace (knuckleballs, forkballs et al).

(10) A sea-going sailing vessel with a traditional Chinese design and used primarily in Chinese waters, having square sails spread by battens, a high stern (poop deck) and (usually) a flat bottom.

(11) A sperm whale equivalent of the melon (cetacean)

(12) To cast aside as junk; discard as no longer of use; to scrap.

1350-1400: From the Middle English joynk & junke (old refuse from boats and ships), from the earlier nautical sense of “old rope or cable”, and the use of junk to describe “old rope and such” may have been influenced by the words “join, joint &, juncture”.  The Middle English junk, jonk, jounke, jonke & junck (a rush; basket made of rushes), from the Old French jonc or junc (rush, reed (also used figuratively to describe “something of little value”), from the Latin iuncus (rush, reed) was once often cited as a source but etymologists have concluded there’s “no evidence of connection”.  In nautical use, the extension from “old rope & cables” to “old refuse from boats, ships & ports” had occurred by the 1660s, travelling inland to “old or discarded articles of any kind” by the late nineteenth century, initially with the implication of reusability.(following the naval tradition with rope) as opposed to “scrap” which (except for metals) had an air of finality.  Saltjunk (salt beef or pork used on long voyages) was first recorded in 1762, the slang for heroin (later used loosely of other injected narcotics) dates from 1925, junk food (the term rather than the product” first appeared in the US in 1971, the culinary equivalent of junk art (from a decade earlier and used by conservative critics to decry some modern art).  Junk mail (unsolicited advertizing delivered to the letterbox was so described in 1954 and was later re-used for the electronic version (“junk email” thought just a letter too much and never caught on) while the term junk bond (a financial instrument (originally bonds) rated below “investment grade” due to a high risk of default by the issuer and thus offered at a high interest rate) emerged in 1979.  The verb, dating from 1803, also owed something the old nautical practice of “cutting up ropes for other purposes” in that it conveyed the idea of “to cut off in lumps”, the modern sense of “to throw away as trash, to scrap” appearing a century-odd later.  The synonyms can thus (depending on context) be rubbish, trash, rubble, debris, detritus, refuse, litter or clutter while (in the sense of (to throw away) they include bin, chuck, chuck away, chuck out, discard, dispose of, ditch, dump, scrap, throw away, throw out, toss or trash.  Junk is a noun & verb, junkie & junker are nouns, junky is a noun & adjective, junklike, junkier & junkiest are adjectives and junked & junking are verbs; the noun plural is junk or (of the sailing vessels) junks.

The use to describe the Chinese sailing vessels dates from 1545–1555 and was from the Portuguese junco, either from or influenced by the Dutch jonk, from the Arabic جُنْك (junk), from the thirteenth century Malay (Austronesian) jong (large boat, ship) or Javanese djong (a variant of djung), from the Old Javanese jong (seagoing ship), ultimately from either the Hokkien 船 (chûn) or the Teochew 船 (zung), from the Proto-Min -džion (ship, boat).  The use in Malay may have been influence by the dialectal Chinese (Xiamen) chûn (which may be compared with the Guangdong (Cantonese) dialect syùhn, and the (Mandarin) Chinese chuán).  In sixteenth century English use it was recorded as giunche & iunco.  Unrelated words include junket and the German Junker.  Junket was from the Middle English jonket (basket made of rushes; food, probably made of sour milk or cream; banquet, feast), from the Medieval Latin iuncta, possibly from the Latin iuncus (rush, reed) and thus possible a doublet of jonquil (a species of daffodil and a shade of yellow).  By the 1520s the meaning had shifted to “feast or banquet”, presumably because of the association with “picnic basket”, leading to the early nineteenth century notion of a “pleasure-trip” which later evolved by the 1880s to mean “a trip made ostensibly for business but which is really for leisure or entertainment”.  Junkets remain common (often well-disguised for expense-claim purposes) and in the gambling business, a junket is a gaming room for which the capacity and limits change daily, often rented out to private vendors who run tour groups through them and give a portion of the proceeds to the main casino.  The idea of a junket being “a delicacy” or “a basket” is long obsolete but remains a culinary niche, describing a dessert made of sweetened curds; it was originally a type of cream cheese, the name gained from it being originally prepared and served in a rush basket.  The English Junker was from the German Junker, from the Middle High German juncherre (young lord; not yet knighted nobleman).  As a term it became associated with Prussia militarism and was used to refer to the stereotypical “narrow-minded and anti-liberal, authoritarian attitudes associated with the “Junker class” (the sometimes impoverished) land-owners of “great Prussian estates”, the families which provided the so many of the officer class of the Prussian and later Imperial German Armies (thus “junkerdom”, “junkerish” & “junkerism” entering the language of political science).

Junk is widely used in derived terms and idiomatic forms including “Jesus junk” (Christian-specific junk mail or other merchandize), “hunk of junk” (a term which adds no meaning but is a compelling rhyme (compared with “heap of junk”, “pile of junk” “load of junk”, all of which mean the same thing) and often heard in IT departments when discussing components more than a year old), “junkaholic” (either a hoarder of what others perceive as junk or an individual who consumes much junk food), “junkhead” (either a drug user or addict (ie a synonym of “junkie”) or in engineering, an always unusual (no close to extinct) design of internal combustion engine (ICE) in which the cylinder head is formed by a dummy piston mounted inside the top of the cylinder, “junk news” (a early 1980s critique of “journalism” consisting of sensationalized trivia (as opposed to the later “fake news” which was intended to mislead rather than being merely entertaining)), “Junk DNA” (in earlier use in genetics, “any portion of the DNA (deoxyribonucleic acid; the so-called “building blocks” or “framework of life”) sequence of a chromosome or a genome with no apparent function” (the term “non-functional DNA” now preferred because there’s now a greater understanding of what was one dismissed as “junk DNA”), “junk in the trunk” (having a big butt), “junk shop” (a shop selling second-hand goods, originally cheap but there are now some “junk shops” with some high-priced items), “ junk drawer” (the place designated for the storage of various miscellaneous, small, but (at least potentially) useful items (and apparently usually the third-drawer down in the kitchen); some residences even have a “junk room”), “junk science” (assertions or methods expressed in the language of science but either with no scientific legitimacy or with data interpreted in a misleading manner), “junk conference” (a nominally “academic” conference run for other purposes (holiday junkets, commercial promotion etc), “junk job” (used variously of employment thought boring, pointless, disrespectable or offering no obvious social benefit, “junkware” (in computing, (1) malicious or unwanted software or (2) software which is buggy or doesn’t work), “junkshot” (in oil drilling, a method to shut off a faulty blowout preventer (BOP) by injecting the BOP with material which will “choke off” the hole), “space junk” (the objects in orbit around the Earth that were created by human activity but which now serve no useful purpose and can be a hazard to satellites (known also as “space debris”), “junk hook” (in whaling, a hook designed for handling or extracting the unwanted material (junk) from the head of a whale) “junkman” (one who works in a “junk yard” (a place where scrapped items (typically cars) are sold for parts or metal recycling).

A little corner in the late Rudi Klein's junkyard, Los Angeles, California.

In the junkyard business, in some jurisdictions, there are cars with “salvage titles” and “junk titles”, both designations related to the condition of a vehicle but serving different purposes and reflecting distinct stages in a vehicle’s lifecycle and potential future.  A Salvage Title can be issued when a vehicle has been damaged or declared a total loss by an insurance company, typically because exceeds a certain percentage of the car's assessed value (75-90%, depending on local regulations).  Despite that, a with a salvage title may be repairable and returned to the road after undergoing proper repairs and inspections although the title usually significantly reduces the resale value and can be a factor in insurance companies limiting or denying subsequent coverage.  A Junk Title (also known as a “Certificate of Destruction”) can be issued for a vehicle that considered irreparable or not safe for use on public roads and thus suitable only for scrap or the salvaging of usable parts.  Once a junk title is issued, the vehicle cannot be registered or driven on public roads again, unlike a salvage title vehicle which can be repaired or restored.  Informally, the terms “junkyard” and “scrapyard” are used interchangeably and while there used to be many “car wreckers”, of late, environmentally respectable titles like “recycling centre” have come into vouge.

The Junkyard: The Rudi Klein Collection

Although well-known in the collector community for its large stocks of rusty and wrecked Porsches, Mercedes-Benz and other notable vehicles from the post-war years, the Californian “junkyard” belonging to Rudi Klein (1936-2001) attracted world-wide interest when details were published of the gems which had for decades been secreted in a large and secure shed on the site.  Mr Klein was a German butcher who in the late 1950s emigrated to the US to work at his trade but quickly discovered a more enjoyable and lucrative living could be had dealing in damaged or wrecked European cars, sometimes selling the whole vehicles and sometimes the parts (“parting out” in junkyard parlance).  His Porsche Foreign Auto business had operated for some time before he received a C&D (cease & desist) letter from the German manufacturer’s US attorneys, the result being the name change in 1967 to Porche (sic) Foreign Auto.

Unlike many collectors, Mr Klein amassed his collection unobtrusively and, astonishingly to many, apparently with little interest in turning a profit on the rarest, despite some of them coming to be worth (at the time of his death), over a million US dollars.  In the way of such things, just what sat unseen in the big shed was the stuff of speculation and rumor, the mystery enhanced by tales of Mr Klein turning the junkyard’s dogs (“junkyard dog” itself an idiomatic use suggesting the particularly aggressive type of canine associated with such a role and applied figuratively also to people of similar temperament) on those who ventured too close to the locked doors although some trusted souls apparently were give a tour on the basis of maintaining the secret and it seems all respected the confidence.  After Mr Klein died in 2001, his two sons preserved the collection untouched but in October 2024, a series of rolling sales will be conducted by the auction house Sotheby’s.

Period photograph of the 1935 Mercedes-Benz 500 K Special Coupé (the “Caracciola Coupé” Roadster-Limousine).

Undoubtedly, the star of the show will be the 1935 Mercedes-Benz 500 K Special Coupé, built by Sindelfingen (the factory’s in-house coach-building house) for the three-time European Grand Prix Championship winner Rudolf Caracciola (1901-1959).  The leading driver of the Mercedes-Benz racing team, it was said of him by Alfred Neubauer (1891–1980; racing manager of the Mercedes-Benz competition department 1926-1955): “He never really learned to drive, he just felt it, the talent came to him instinctively”.  The one-off 500 K (W29, deconstructed as 5.0 litre (306 cubic inch) straight-eight with kompressor (supercharger)) was a “gift” (ie part of his “package” as a factory driver) and confusingly tagged (the build-sheet is included in the documentation) by Sindelfingen as a “Roadster-Limousine” which neither etymologically nor by coach-building conventions makes sense but was explained by the car being “built on the chassis of a 500 K Special Roadster with limousine-like fittings & appointments.”  As a basis, the sleek 500 K Special Roadster was illustrious enough, described in the post-war years as “the brightest glint of a golden age” so the lines and unique provenance of the “Caracciola Coupé” will attract much interest.

The “Caracciola Coupé” in Mr Klein's shed

It’s believed Caracciola used the car until the late 1930s when it is said to have passed into the hands of Count Galeazzo Ciano (1903–1944; Italian foreign minister 1936-1944), notable both for his entertaining (if not wholly reliable) diaries and having married the daughter of Benito Mussolini (1883-1945; Duce (leader) & prime-minister of Italy 1922-1943).  The marriage was certainly a good career move (the Italians would joke of the one they called “ducellio”: “the son-in-law also rises”) although things didn’t end well, Il Duce having him shot (at the insistence of Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945), something which over the years must have drawn the envy of many a father-in-law (and the sentiment was expressed by Winston Churchill (1875-1965; UK prime-minister 1940-1945 & 1951-1955) who didn't always approve of his daughters' choices).  There seems to be no evidence of Count Ciano’s stewardship but even if not true, it’s certainly the sort of car he’d liked to have owned.  Things become murky after the outbreak of World War II (1939-1945) but in 1962 it was discovered in Ethiopia, covered in tarpaulins and hidden in a manure pile.  That may hint at a (probably unrelated) connection between count & car because in 1935, during the Second Italo-Ethiopian War (the last war of the era of European colonialism which even at the time seemed to many an embarrassing anachronism), Ciano had commanded the Regia Aeronautica's (Royal Air Force) 15th Bomber Flight (nicknamed La Disperata (the desperate ones)) in air-raids on primitive tribes during the Italian invasion, being awarded the Medaglia d'argento al valor militare (Silver Medal of Military Valor), prompting some to observe he deserved a gold medal for bravery in accepting a silver one, his time in the air having hardly exposed him to danger.

The “Caracciola Coupé”, "Best in Class" winner, Pebble Beach, Monterey County, California, 1978.

The coupé in 1963 then travelled to the US where it was subject to an 18 month restoration before being entered in the 1966 Pebble Beach Concours d’Elegance, finishing second in class, behind a Bugatti Royale (type 41), beginning a 13 year career as a fixture on the North American concours & classic car circuit becoming, a little ironically given its later 44-year hiatus, one of best-known Mercedes-Benz of the “supercharger era”.  Back on the manicured lawns of Pebble Beach in 1978, it went one better than a decade earlier, this time taking first in class and in 1979 it was purchased by Mr Klein who exhibited at a show at least once.  After that, it was left to languish in the big shed but it remained solid, mechanically original (apparently, in the restoration only the paint, chrome, upholstery and perishable parts were replaced) so as re-commissioning projects go, while unlikely to be “cheap”, it won’t be intimidating.  Sotheby’s haven’t published a price estimate but most are suggesting it should achieve between US$3-4 million.

At auction also among dozens will be a 1957 Mercedes-Benz 300 SL Roadster, a rare (one of 29) 1955, aluminum-bodied Mercedes-Benz 300 SL Gullwing (long thought lost and likely to realize close to US$10 million), a trio of damaged Lamborghini P400 Miuras, the one-off Iso Griffo A3/L Spider prototype (which will need to have its unique front coachwork re-created but will still command over US$1 million) and a 1939 Horch 855 Special Roadster, always prized for its rakish lines and the only 855 known to have survived the war.
