Demand

Demand (pronounced dih-mand (U) or dee–mahnd (non-U))

(1) To ask for with proper authority; claim as a right.

(2) To ask for peremptorily or urgently.

(3) To call for or require as just, proper, or necessary.

(4) In law, to lay formal claim to.

(5) In law, to summon, as to court.

(6) An urgent or pressing requirement.

(7) In economics, the desire to purchase, coupled (hopefully) with the power to do so.

(8) In economics, the quantity of goods that buyers will take at a particular price.

(9) A requisition; a legal claim.

(10) A question or inquiry (archaic).

1250-1300: From Middle English demaunden and Anglo-French demaunder, derived from the Medieval Latin dēmandāre (to demand, later to entrust) equivalent to  + mandāre (to commission, order).  The Old French was demander and, like the English, meant “to request” whereas "to ask for as a right" emerged in the early fifteenth century from Anglo-French legal use.  As used in economic theory and political economy (correlating to supply), first attested from 1776 in the writings of Adam Smith.  The word demand as used by economists is a neutral term which references only the conjunction of (1) a consumer's desire to purchase goods or services and (2) hopefully the power to do so.  However, in general use, to say that someone is "demanding" something does carry a connotation of anger, aggression or impatience.  For this reason, during the 1970s, the language of those advocating the rights of women to secure safe, lawful abortion services changed from "abortion on demand" (ie the word used as an economist might) to "pro choice".  Technical fields (notably economics) coin derived forms as they're required (counterdemand, overdemand, predemand et al).  Demand is a noun & verb, demanding is a verb & adjective, demandable is an adjective, demanded is a verb and demander is a noun; the noun plural is demands.

Video on Demand (VoD)

Directed by Tiago Mesquita with a screenplay by Mark Morgan, Among the Shadows is a thriller which straddles the genres, elements of horror and the supernatural spliced in as required.  Although in production since 2015, with the shooting in London and Rome not completed until the next year, it wasn’t until 2018 when, at the European Film Market, held in conjunction with the Berlin International Film Festival, that Tombstone Distribution listed it, the distribution rights acquired by VMI, Momentum and Entertainment One, and VMI Worldwide.  In 2019, it was released progressively on DVD and video on demand (VoD), firstly in European markets, the UK release delayed until mid-2020.  In some markets, for reasons unknown, it was released with the title The Shadow Within.

Video on Demand (VoD) and streaming services are similar concepts in video content distribution but there are differences.  VoD is a system which permits users to view content at any time, these days mostly through a device connected to the internet across IP (Internet Protocol), the selection made from a catalog or library of available titles and despite some occasionally ambiguous messaging in the advertising, the content is held on centralized servers and users can choose directly to stream or download.  The VoD services is now often a sub-set of what a platform offers which includes content which may be rented, purchased or accessed through a subscription.

Streaming is a method of delivering media content in a continuous flow over IP and is very much the product of the fast connections of the twenty-first century.  Packets are transmitted in real-time which enables users to start watching or listening without waiting for an entire file (or file set) to download, the attraction actually being it obviates the need for local storage.  There’s obviously definitional and functional overlap and while VoD can involve streaming, not all streaming services are technically VoD and streaming can also be used for live events, real-time broadcasts, or continuous playback of media without specific on-demand access. By contrast, the core purpose of VoD is to provide access at any time and streaming is a delivery mechanism, VoD a broad concept and streaming a specific method of real-time delivery as suited to live events as stored content.

The Mercedes-Benz SSKL and the Demand Supercharger

The Mercedes-Benz SSKL was one of the last of the road cars which could win top-line grand prix races.  An evolution of the earlier S, SS and SSK, the SSKL (Super Sports Kurz (short) Leicht (light)) was notable for the extensive drilling of its chassis frame to the point where it was compared to Swiss cheese; reducing weight with no loss of strength.  The SSKs and SSKLs were famous also for the banshee howl from the engine when the supercharger was running; nothing like it would be heard until the wail of the BRM V16s twenty years later.  It was called a demand supercharger because, unlike some constantly-engaged forms of forced-induction, it ran only on-demand, in the upper gears, high in the rev-range, when the throttle was pushed wide-open.  Although it could safely be used for barely a minute at a time, when running, engine power jumped from 240-odd horsepower to over 300.  The number of SSKLs built has been debated and the factory's records are incomplete but most historians suggest it was either four or five, all completed (or modified from earlier builds) between 1929-1932.  The SSK had enjoyed success in competition but even in its heyday was in some ways antiquated and although powerful, was very heavy, thus the expedient of the chassis-drilling intended to make it competitive for another season.  Lighter (which didn't solve but at least to a degree ameliorated the high tyre wear) and easier to handle than the SSK (although the higher speed brought its own problems, notably in braking), the SSKL enjoyed a long Indian summer and even on tighter circuits where its bulk meant it could be out-manoeuvred, sometimes it still prevailed by virtue of sheer power.

Sometimes too it got lucky.  When the field assembled in 1931 for the Fünfter Großer Preis von Deutschland (fifth German Grand Prix) at the Nürburgring Nordschleife, even the factory acknowledged that at 1600 kg (3525 lb), the SSKLs, whatever their advantage in horsepower, stood little chance against the nimble Italian and French machines which weighed-in at literally less than half that.  However, on the day there was heavy rain and most of race was conducted on a soaked track and the lightweight, twitchy Alfa Romeos, Maseratis and the especially skittery Bugattis proved less suited to the slippery surface than the truck-like but stable SSKL, the lead built up in the rain enough to secure victory even though the margin narrowed as the track dried.  Time and the competition had definitely caught up by 1932 however and it was no longer possible further to lighten the chassis or increase power so the factory had aerodynamics specialist Baron Reinhard von Koenig-Fachsenfeld (1899-1992) design a streamlined body, the lines influenced by wartime aeronautical experience.  This coaxed from the SSKL, one last successful season.  Crafted in aluminum by Vetter in Cannstatt, it was mounted on Manfred von Brauchitsch's (1905-2003) race-car and proved its worth at the at the Avus race in May 1932; with drag reduced by a quarter, the top speed increased by over 12 mph (20 km/h) and the SSKL won its last major trophy on the unique circuit which rewarded straight-line speed like no other.  It was the last of the breed.  Subsequent grand prix cars would be pure racing machines with none of the compromises demanded for road-use.

1475–1485: From the Middle English reduccion, from the earlier reduccion, from the Middle French reduction, from the Latin reductiōnem & reductiōn- (stem of reductiō (a “bringing back”)) the construct being reduct(us) (past participle of redūcere (to lead back) + -iōn- (the noun suffix).  The construct in English was thus reduc(e), -ion.  Reduce was from the Middle English reducen, from the Old French reduire, from the Latin redūcō (reduce), the construct being re- (back) + dūcō (lead).  The –ion suffix was from the Middle English -ioun, from the Old French -ion, from the Latin -iō (genitive -iōnis).  It was appended to a perfect passive participle to form a noun of action or process, or the result of an action or process.  Reduction, reductivism, reductionistic & reductionism are nouns, reductionist is a noun & adjective, reductional & reductive are adjectives; the noun plural is reductions.  Forms like anti-reduction, non-reduction, over-reduction, pre-reduction, post-reduction, pro-reduction, self-reduction have been created as required.

In philosophy & science, reductionism is an approach used to explain complex phenomena by reducing them to their simpler, more fundamental components.  It posits that understanding the parts of a system and their interactions can provide a complete explanation of the system as a whole an approach which is functional and valuable is some cases and to varying degrees inadequate in others.  The three generally recognized classes of reductionism are (1) Ontological Reductionism, the idea that reality is composed of a small number of basic entities or substances, best illustrated in biology where life processes are explained by reducing things to the molecular level.  (2) Methodological Reductionism, an approach which advocates studying systems by breaking into their constituent parts, much used in psychology where it might involve studying human behavior by examining neurological processes.  (3) Theory Reductionism which involves explaining a theory or phenomenon in one field by the principles of another, more fundamental field as when chemistry is reduced to the physics or chemical properties explained by the operation of quantum mechanics.  Reduction has been an invaluable component in many of the advances in achieved in science in the last two-hundred-odd years and some of the process and mechanics of reductionism have actually been made possible by some of those advances.  The criticism of an over-reliance on reductionism in certain fields in that its very utility can lead to the importance of higher-level structures and interactions being overlooked; there is much which can’t fully be explained by the individual parts or even their interaction.  The diametric opposite of reductionism is holism which emphasizes the importance of whole systems and their properties that emerge from the interactions between parts.  In philosophy, reductionism is the position which holds a system of any level of complexity is nothing but the sum of its parts and an account of it can thus be reduced to accounts of individual constituents.  It’s very much a theoretical model to be used as appropriate rather than an absolutist doctrine but it does hold that phenomena can be explained completely in terms of relations between other more fundamental phenomena: epiphenomena.  A reductionist is either (1) an advocate of reductionism or (2) one who practices reductionism.

Reductionism: Lindsay Lohan during "thin phase".

The adjective reductive has a special meaning in Scots law pertaining to reduction of a decree or other legal device (ie something rescissory in its effect); dating from the sixteenth century, it’s now rarely invoked.  In the sense of “causing the physical reduction or diminution of something” it’s been in use since the seventeenth century in fields including chemistry, metallurgy, biology & economics, always to convey the idea of reduces a substance, object or some abstract quantum to a lesser, simplified or less elaborated form.  At that time, it came to be used also to mean “that can be derived from, or referred back to; something else” and although archaic by the early 1800s, it existence in historic texts can be misleading.  It wasn’t until after World War II (1939-1945) that reductive emerged as a derogatory term, used to suggest an argument, issue or explanation has been “reduced” to a level of such simplicity that so much has been lost as to rob things of meaning.  The phrase “reductio ad absurdum” (reduction to the absurd) is an un-adapted borrowing from the Latin reductiō ad absurdum, and began in mathematics, logic (where it was a useful tool in deriving proofs in fields like).  In wider use, it has come to be used of a method of disproving a statement by assuming the statement is true and, with that assumption, arriving at a blatant contradiction; the synonyms are apagoge & “proof by contradiction”.

Single-family houses (D-Zug) built in 1922 on the principle of architectural reductionism by Heinrich Tessenow in collaboration with Austrian architect Franz Schuster (1892–1972), Moritzburger Weg 19-39 (the former Pillnitzer Weg), Gartenstadt Hellerau, Dresden, Germany.

As a noun, a reductivist is one who advocates or adheres to the principles of reductionism or reductivism.  In art & architecture (and some aspects of engineering) this can be synonymous with the label “a minimalist” (one who practices minimalism).  As an adjective, reductivist (the comparative “more reductivist”, the superlative “most reductivist”) means (1) tending to reduce to a minimum or to simplify in an extreme way and (2) belonging to the reductivism movement in art or music.  The notion of “extreme simplification” (a reduction to a minimum; the use of the fewest essentials) has always appealed some and appalled others attracted to intricacy and complexity.  The German architect Professor Heinrich Tessenow (1876-1950) summed it up in the phrase for which he’s remembered more than his buildings: “The simplest form is not always the best, but the best is always simple.”, one of those epigrams which may not reveal a universal truth but is probably a useful thing to remind students of this and that lest they be seduced by the process and lose sight of the goal.  Tessenow was expanding on the principle of Occam's Razor (the reductionist philosophic position attributed to English Franciscan friar & theologian William of Ockham (circa 1288–1347) written usually as Entia non sunt multiplicanda praeter necessitatem (literally "Entities must not be multiplied beyond necessity" which translates best as “the simplest solution is usually the best.

Reductio in extrema

1960 Lotus Elite Series 1 (left) and at the Le Mans 24 Hour endurance classic, June 1959 (left) Lotus Elite #41 leads Ferrari 250TR #14. The Ferrari (DNF) retired after overheating, the Elite finishing eighth overall, winning the 1.5 litre GT class.

Weighing a mere 500-odd kg (1100 lb), the early versions of the exquisite Lotus Elite (1957-1963) enchanted most who drove it but the extent of the reductionism compromised the structural integrity and things sometimes broke when used under everyday conditions which of course includes potholed roads.  Introduced late in 1961 the Series 2 Elite greatly improved this but some residual fragility was inherent to the design.  On the smooth surfaces of racing circuits however, it enjoyed an illustrious career, notable especially for success in long-distance events at the Nürburgring and Le Mans.  The combination of light weight and advanced aerodynamics meant the surprisingly powerful engine (a robust unit which began life power the water pumps of fire engines!) delivered outstanding performance, frugal fuel consumption and low tyre wear.  As well as claiming five class trophies in the Le Mans 24 hour race, the Elite twice won the mysterious Indice de performance (an index of thermal efficiency), a curious piece of mathematics actually designed to ensure, regardless of other results, a French car would always win something.

Colin Chapman (1928–1982), who in 1952 founded Lotus Cars, applied reductionism even to the Tessenow mantra in his design philosophy: “Simplify, then add lightness.”  Whether at the drawing board, on the factory floor or on the racetrack, Chapman seldom deviated from his rule and while it lent his cars sparking performance and delightful characteristics, more than one of the early models displayed an infamous fragility.  Chapman died of a heart attack which was a good career move, given the likely legal consequences of his involvement with John DeLorean (1925–2005) and the curious financial arrangements made with OPM (other people's money) during the strange episode which was the tale of the DMC DeLorean gullwing coupé.

1929 Mercedes-Benz SSKL blueprint (recreation, left) and the SSKL “streamliner”, AVUS, Berlin, May 1932 (right).

The Mercedes-Benz SSKL was one of the last of the road cars which could win top-line grand prix races.  An evolution of the earlier S, SS and SSK, the SSKL (Super Sports Kurz (short) Leicht (light)) was notable for the extensive drilling of its chassis frame to the point where it was compared to Swiss cheese; reducing weight with no loss of strength.  The SSK had enjoyed success in competition but even in its heyday was in some ways antiquated and although powerful, was very heavy, thus the expedient of the chassis-drilling intended to make it competitive for another season.  Lighter (which didn't solve but at least to a degree ameliorated the high tyre wear) and easier to handle than the SSK (although the higher speed brought its own problems, notably in braking), the SSKL enjoyed a long Indian summer and even on tighter circuits where its bulk meant it could be out-manoeuvred, sometimes it still prevailed by virtue of sheer power.  By 1932 however the engine’s potential had been reached and there was no more metal which could be removed without dangerously compromising safety.  The solution was an early exercise in aerodynamics (“streamlining” the then fashionable term), an aluminium skin prepared for the 1932 race held on Berlin’s AVUS (Automobil-Versuchs und Übungsstraße (automobile traffic and practice road)).  The reduction in air-resistance permitted the thing to touch 255 km/h (158 mph), some 20 km/h (12 mph) more than a standard SSLK, an increase the engineers calculated would otherwise have demanded another 120 horsepower.  The extra speed was most useful at the unique AVUS which comprised two straights (each almost six miles (ten kilometres) in length) linked by two hairpin curves, one a dramatic banked turn.  The SSKL was the last of the breed, the factory’s subsequent Grand Prix machines all specialized racing cars.

Reduction gears: Known casually as "speed reducers", reduction gears are widely used in just about every type of motor and many other mechanical devices.  What they do is allow the energy of a rotating shaft to be transferred to another shaft running at a reduced speed (achieved usually by the use of gears (cogs) of different diameters.

In chemistry, a reduction is the process or result of reducing (a reaction in which electrons are gained and valence is reduced; often by the removal of oxygen or the addition of hydrogen) and as an example, if an iron atom (valence +3) gains an electron, the valence decreases to +2.  Linguistically, it’s obviously counterintuitive to imagine a “reduced atom” is one which gains rather than loses electrons but the term in this context dates from the early days of modern chemistry, where reduction (and its counterpart: “oxidation”) were created to describe reactions in which one substance lost an oxygen atom and the other substance gained it.   In a reaction such as that between two molecules of hydrogen (2H2)and one of oxygen (O2) combining to produce two molecules of water (2H2O), the hydrogen atoms have gained oxygen atoms and were said to have become “oxidized,” while the oxygen atoms have “lost them” by attaching themselves to the hydrogens, and were thus “reduced”.  Chemically however, in the process of gaining an oxygen atom, the hydrogen atoms have had to give up their electrons and share them with the oxygen atoms, while the oxygen atoms have gained electrons, thus the seeming paradox that the “reduced” oxygen has in fact gained something, namely electrons.

Proboscis

Proboscis (pronounced proh-bos-is or proh-bos–kis)

(1) A long flexible prehensile trunk or snout, as that of an elephant.

(2) In zoology, any elongated tube from the head or connected to the mouth.

(3) In entomology & malacology, the elongate, protruding mouth parts of certain insects and certain invertebrates like insects, worms and molluscs, adapted for sucking or piercing (more popularly called “the beak”).

(4) Any of various elongate feeding, defensive, or sensory organs of the oral region, as in certain leeches and worms.

(5) In facetious use, the human nose, the use probably roughly with the size of prominence of the nose.

(6) In informal use, as applied in geography, engineering, geometry etc, any protrusion vaguely analogous with the human nose.

1570-1580: From the Latin proboscis (trunk of an elephant), from the Ancient Greek προβοσκίς (proboskís) (elephant's trunk (literally “feeder; means for taking food"), the construct being προ- (pro-) (before) +‎ βόσκω (bóskō) (to nourish, to feed”), from boskesthai (graze, be fed), from the stem bot- (source of botane (grass, fodder) and from which English gained botanic), from the primitive Indo-European root gwehs (source also of βοτάνη (botánē) (grass, fodder) + -is (the noun suffix).  The related terms include nose beak, organ, snoot, snout, trunk and probably dozens of slang forms.  Other descendents from the Latin include the Italian proboscide, the Portuguese probóscide and the Spanish probóscide.  Proboscis & proboscidean are nouns and proboscidate is an adjective; the noun plural is proboscises or proboscides.  The Greek derived form of the plural (proboscides) appears often in the technical literature that built using the conventions of English (proboscises) appears to be the common general form, rare though it is.

#Freckles: Lindsay Lohan’s nose.

Aerodynamics were of interest to some even in the early days of the automobile and those involved in motorsport were more interested than most.  For decades, the interest manifested mostly in the art of streamlining, the reduction of drag and research, accomplished mostly without wind-tunnel testing and obviously without computers, tended to produce cigar-shaped bodies with as few protrusions as possible.  Drag in many cases was certainly minimized, some of the shapes rendered in the 1920s & 1930s delivering drag coefficients (CD) impressive even by twenty-first century standards but it took a long time before fully it was understood that the fluid dynamics (the behavior of air) at the rear of a vehicle could be as significant as the more obvious disturbances at the front.  Not un-related to this was that it also took time (and not a few deaths) before it was appreciated quite how vital was the trade-off between drag-reduction and the downforce needed to ensure cars did not “take-off” from the surface, resulting in instant instability.

The 1923 Benz Tropfenwagen (teardrop vehicle) (left) not only used an aerodynamic nose using lessons learned from military aviation during World War I (1614-1918) but was able to optimize the shape because the engine was mid-mounted, something would wouldn’t become commonplace in Formula One for over thirty years.  The front-engined 1931 Grand Prix Mercedes-Benz SSKL (centre) made few concessions to aerodynamics, relying on power and weight-trimming but when that approach reached its evolutionary dead-end, a streamlined SSKL (1932, right) was crafted, limitations on what could be done with the nose imposed by the bulk and height of the engine.

That the early attempts at streamlining might induce aircraft-like “take-offs” was not surprising given so much of the available data came from work in ballistics and aeronautics where lift is desirable and as speeds rose, it became clear what would need also to be considered was what air was doing underneath the vehicle, some cars obviously with "just enough lift to be a bad airplane" as one driver put it.  That increase in speed in itself imposed a limit on research, the terminal velocities suddenly possible exceeding the capacity of ground-effects based wind tunnels and few manufacturers had access to test facilities with straights of sufficient length to match those on some race-tracks.  High-speed testing was thus sometimes undertaken by racing drivers at speeds rarely before explored, something complicated by being among disrupted air induced by surrounding cars and some unpredictable behavior ensued; it was actually remarkable there weren’t more fatalities than there were.

In the embryonic study of aerodynamics, one of the first conclusions (correctly) drawn was that few changes produced more dramatic improvements than lowering and optimizing the shame of the nose.  At the time, it was something not as simple as it sounded, engines mounted usually close to the nose and in the era, those usually long-stroke engines were tall, often in-line units, a shape which imposed limits on what was possible.  Jaguar used dry-sump lubrication on the D-Type (and the road-going derivative the XKSS) to allow the nose to drop a few inches compared with its predecessor, an expedient also adopted by Mercedes-Benz for their 300 SL (W198, 1954-1957) and 300 SLR (W196S, 1955), more lowering still made possible by mounting the power-plant at an acute angle.

In the same era, Maserati, impressed by the speed of the Mercedes-Benz W196 when fitted with the "streamliner" body used on the faster circuits and, apparently without the benefit of a wind-tunnel, developed its own partially enclosed bodywork for its 250F Grand Prix car but it also developed, quite serendipitously, an even more effective shape and it was initially known as the “long-nose” 250F until it proved so successful it was adopted as the definitive 250F body.

The long and short of it: The Ferrari 250 LM in long (left) and short (right) nose configuration.

Ferrari and others noted the gains aerodynamics provided and among engineers, some fairly inaccurate (though broadly indicative) "rules of thumb" emerged, based usually on the calculation that for every one inch (25 mm) reduction in nose height, an effective gain of so many horsepower would be realized.  Precise or not, the method, honed by slide-rules, lingered until computer calculations and wind tunnels began more accurately to produce the numbers.  Ferrari’s first mid-engined sports car, the 250 LM (1963-1965), was one of the vehicles to benefit from a nose job, the revised bodywork fashioned by coachbuilder Piero Drogo (1926–1973) who had formed the Modena-based Carrozzeria Sports Cars to service the ecosystem of sports cars that congregated in the region.  There was an urban myth the Drogo nose was created so an “FIA standard size” suitcase could be carried (to convince the regulatory body it was a car for road and track rather than a pure racing machine) but it was really was purely for aerodynamic advantage.

Ferrari 250 LM, the short-nose chassis 6321 (left) and the long-nose (5893) right,

Testing confirmed the “Drogo nose” certainly conferred aerodynamic benefits on the 250 LM but the change brought it own difficulties because Ferrari was at the time attempting to convince the Fédération Internationale de l'Automobile (the FIA; the International Automobile Federation) the 250 LM should be homologated in the Grand Turismo (GT) category so it could contest the World Sports Car Championship.  This was being done using the argument the 250 LM was a mere update of the 250 GTO, despite the 250 LM having a different engine & transmission (mid rather than front-mounted) and a different body.  For homologation to be granted, there had to be 100 essentially identical examples of the model produced and given (1) there were such fundamental differences from the earlier 250s and (2) not even two dozen 250 LMs had then been produced, the FIA was understandably reticent.  However, as a gesture of good faith, Ferrari undertook (eventually) to produce the requisite 100 (even displaying what proved to be a one-off road-going version, complete with a plush interior and electric windows, to bolster the claim it belonged in the GT category) and issued a very public recall notice for all 250 LMs to be returned to the factory to be fitted with the Drogo nose.  One 250 LM (chassis 6321) however was by then being raced in Australia which was a long way away so that one was quietly overlooked (the FIA either turned a blind eye or didn't check), meaning that at least for some time it was the only “short-nosed” 250 LM left in the world, although it’s known at least two have since be converted back to their original specification.  Eventually, 32 250 LMs would be built and the FIA didn’t relent, forcing the car to compete in the 1965 championship against much faster machinery in the prototype class but it was fast enough and importantly, more reliable than the more fragile prototypes and chassis 5893 won the 1965 Le Mans 24 hour endurance race, Ferrari's last victory in the event.

Ferrari 275 GTB short (left) and long-nose (right).

The 1960s saw the last generation of Ferrari cars styled without the use of wind tunnels or much in the way of electronic assistance.  Even for the road cars, as speeds rose, some high speed instability was occasionally noted but this became pronounced with the cars were used in competition, especially on the faster tracks with the long straights.  Accordingly, knowing there would be a competition version of the 275 GTB (the 275 GTB/C) a long-nose was created which was also used on other models.  The 275 GTB/C was notable also for marking the swan song of the classic Borrani wire-spooked wheels on Ferrari competition cars, the elegant, chromed creations no longer strong enough to handle the increase loads in extreme conditions, replaced by aluminium or magnesium castings.

Across the Atlantic, on the NASCAR (National Association of Stock Car Auto Racing) circuits, the manufacturers had reached a dead end imposed by their regulatory body.  By 1969 the NASCAR authorities had fine-tuned their rules, restricting engine power and mandating a minimum weight so manufacturers, finding it increasingly harder to cheat, resorted to the then less policed field of aerodynamics, ushering what came to be known as the brief era of the "aero-cars".  Dodge began by making modifications to their Charger which smoothed the air-flow, labelling it the Charger 500 in a nod to the rules which demanded 500 identical models for eligibility.  It proved less successful than hoped and Dodge apparently gave up on the design, producing on 392 (although to make up the numbers they did the next year add an unrelated “500” option to the Charger line and NASCAR generously turned their blind eye).  Not discouraged however, Dodge recruited engineers from Chrysler's soon to be shuttered (as arms control treaties with the USSR loomed) aerospace & missile division and quickly created the Daytona, adding to the 500 a protruding nosecone and high wing at the rear.  Even now, the nosecone would be thought extreme but it worked on the track and this time the required 500 were actually built.  NASCAR responded by again moving the goalposts, requiring manufacturers to build at least one example of each vehicle for each of their dealers before homologation would be granted, something which would demand thousands of cars.  Accepting the challenge, in 1970 Dodge's corporate stablemate Plymouth duly built about two-thousand of their similar aero car, the Road Runner Superbird, an expensive exercise given they reportedly lost money on each one.  Now more unhappy than ever, NASCAR lawyered-up, drafted rules rendering the aero-cars uncompetitive and their brief era ended.  So extreme in appearance were the cars they proved at the time sometimes hard to sell and some were actually converted back to the standard specification to get them out of the showroom.  Views changed over time and they're now much sought by collectors, selling for up to US$500,000 in the most desirable configuration.

As imposing as the noses developed for the Daytona and Superbird were, it may have been that much of the modification was wasted effort and an application of the Europeans’ old “inch by inch” rule of thumb might have been as effective.  The nose jobs Ford in 1969 applied to their Torino Talladega and Mercury’s Cyclone Spoiler II were modest compared to what Chrysler did.  The grill was flattened, a la the Charger 500, the front bumper was replaced with a re-shaped version of the rear unit from a 1969 Fairlane which functioned effectively as an air-dam and the leading edge of the nose was extended and re-shaped dowwards.  The effect was subtle but on the track, appeared to confer a similar advantage to the one Chrysler’s rocket scientists had achieved but Ford had also made some changes which lowered the centre of gravity and improved the under-body air-flow.  Quite what this achieved has never been documented but the drivers were certainly convinced, retaining the Talladegas and Cyclone Spoilers as long as possible, the shapes proving much more efficient than their sleek-looking successors.

When in 1973 regulations forced Porsche to fit more substantial bumpers to the 911 (in production since 1964), it necessitated a change to the front bodywork, the earlier cars became known as the "long hood" and subsequent models the "short hood", both references to the hood (bonnet) being shortened to accommodate the unsightly battering rams.  More nose jobs would follow.  Between 1982-1989, Porsche produced three generations of the 911 (930) Turbo S with the flachbau (slantnose) bodywork, a total of 948 believed built.  It seems there were a few, hand-built prototypes completed by 1980 in addition to one completed under the factory’s Sonderwunsch (Special wishes) programme for an individual who was either well-connected or a very good customer.  The 58 first generation cars lack the pop-up headlamps so associated with the design, instead using smooth, flat-faced wings with a fibreglass front valance assembly containing twin lamps either side below the bumper.  Nicknamed the “hammerhead”, the styling divided opinion and was anyway found not to be compliant with regulations in some markets, thus the substitution of the pop-up headlamps which appeared during 1983.  As was typical of much which emerged from the programme, the cars were built with a variety of Sonderwunsch options so there was no one consistent specification.

1973 Porsche 911 Carrera RS from the long hood era (left) and 1975 Porsche 911 Turbo (930) with the short hood used since the 1974 model year (right).  Such is the lure of the early 911s something of a cottage industry has emerged, devoted to "backdating" later cars.     

The second generation flachbau yielded 204 cars, the styling updated with a simplified air dam containing driving lights and a centrally mounted oil-cooler, the pop-up headlamps relocated to front wings, a much admired feature the optional air-intake vents above the pop-ups, something borrowed from the 935 track cars.  Again, other than the structural changes, there was no standard configuration, each flachbau reflecting the buyer’s ticking of the option list and any special wishes the factory was able to satisfy.  The third generation were the most numerous with 686 produced, the increased volume reflecting the effort made to ensure the cars could be made available in the lucrative US market which eventually received 630 flachbaus.  More standardized, production shifted from the Sonderwunsch’s Restoration and Repair Department facility (Werks 1) to the line in Zuffenhausen where the standard 930s were assembled though for ease of completion (and to maintain exclusivity) the cars were transferred to the Sonderwunsch for finishing and detailing.

Thomas Wedders (AKA Thomas Wadhouse) from Yorkshire, England (a member of a travelling "freak show" circus) is recorded as having enjoyed (sic) the world's longest known human nose, claimed to be some 200mm (7¾ inches) in length.  In the absence of any verified evidence, the truth of that can't be known but it may be assumed his nose was very big.  The current record is held by Mehmet Özyürek (b 1949) of Türkiye, his nose officially measured and found to be 88mm (3½ inches).

Kestrel

Kestrel (pronounced kes-truhl)

(1) In ornithological taxonomy, a common small falcon (especially the Falco tinnunculus), of northern parts of the Eastern Hemisphere, notable for hovering in the air with its head to the wind, its primary diet the small mammals it plucks from the ground.

(2) Any of a number of related small falcons.

(3) A brand-name, used severally (initial upper case).

1400–1450: From the late Middle English castrell, from the Middle English castrel & staniel (bird of prey), from the Middle French cresserelle & quercerelle (bird of prey), a variant of the Old French crecerelle, from cressele (rattle; wooden reel), from the unattested Vulgar Latin crepicella & crepitacillum, a diminutive of crepitāculum (noisy bell; rattle), from the Classical Latin crepitāre (to crackle, to rattle), from crepāre (to rustle). The connection with the Latin is undocumented and based on the folk belief their noise frightened away other hawks.  However, some etymologists contest the connection with the Latin forms and suggest a more likely source is a krek- or krak- (to crack, rattle, creak, emit a bird cry), from the Middle Dutch crāken (to creak, crack), from the Old Dutch krakōn (to crack, creak, emit a cry), from the Proto-West Germanic krakōn, from the Proto-Germanic krakōną (to emit a cry, shout), from the primitive Indo-European gerg- (to shout).  It was cognate with the Old High German krahhōn (to make a sound, crash), the Old English cracian (to resound) and the French craquer (to emit a repeated cry, used of birds).  All however concur the un-etymological -t- probably developed in French.  Kestrel is a noun; the noun plural is kestrels.

In taxonomy, the variations include the American kestrel (Falco sparverius), the banded kestrel (Falco zoniventris), the common kestrel (Falco tinnunculus), the greater kestrel (Falco rupicoloides), the grey kestrel (Falco ardosiaceus), the lesser kestrel (Falco naumanni), the nankeen kestrel (Falco cenchroides), the Seychelles kestrel (Falco araeus) and the spotted kestrel (Falco moluccensis).  Although the bird had earlier been described as the castrell, in the early seventeenth century the small falcons were more commonly known as windhovers, the construct being wind + hover, reflecting the observations of the ability of the birds literally to hover when facing into the wind.  A now more memorable term however was the one dating from the 1590s: The windfucker (or the fuckwind).  In English, for almost two centuries, any use of the F-word could be controversial and its very existence seemed to make uncomfortable one faction of lexicographers who at one point managed to strike it from almost all dictionaries of English.  They were also revisionists of historical interpretation and claimed windfucker & fuckwind were errors in transcription, the original folk-names being windsucker & suckwind.  To give theis theory a bit of academic gloss, they assembled charts of regionally specific pronunciation in the Late Middle and early Modern English to illustrate the extent to which the archaic long S character ( ſ ) often took the place of an < s > at both the beginnings and middle of words, the argument being the long S was misread as a lowercase ( f ).

It was an intellectually clever way to attempt to remove vulgarity from English but etymologists today give little credence to the theory, noting that the undisputed French sources provide no support.  It may be assumed kestrels came to be called windfuckers & fuckwinds because when displaying their expertise at hovering in the air when facing into the wind, the movements of their bodies does make it look as if airborne copulation is in progress.  Of note too is that in the sixteenth and seventeenth centuries, the same disapprobation didn’t always attach to “fuck” which, although there was a long history of meaning “fornication”, it had also been in figurative use to describe anything from “plough furrows in a field” to “chop down a tree”.  Fuck was from the Middle English fukken and probably of Germanic origin, from either the Old English fuccian or the Old Norse fukka, both from the Proto-Germanic fukkōną, from the primitive Indo-European pewǵ- (to strike, punch, stab).  It was probably the popularity of use as well as the related career as a general-purpose vulgar intensifier which attracted such disapproval.  By 1795 it had been banished from all but the most disreputable dictionaries, not to re-appear until the more permissive 1960s.

Windfucker thus became archaic but not wholly extinct because it appears in at least one British World War II (1939-1945) diary entry which invoked the folk-name for the bird to describe the German liaison & communications aircraft, the Fieseler Fi 156 Storch (stork), famous for its outstanding short take-off & landing (STOL) performance and low stalling speed of 30 mph (50 km/h) which enabled it almost to hover when faced into a headwind.  The Storch’s ability to land in the length of a cricket pitch (22 yards (20.12 m)) made it a useful platform for all sorts of operations, the most famous of which was the daring landing on a mountain-top in northern Italy to rescue the deposed Duce (Benito Mussolini, 1883-1945; Duce (leader) & prime-minister of Italy 1922-1943).  So short was the length of the strip of grass available for take-off that even for a Storch it was touch & go (especially with the Duce’s not inconsiderable weight added) but with inches to spare, the little plane safely delivered its cargo.

Riley was one of the storied names of the British motor industry, beginning as a manufacturer of bicycles in 1896, an after some early experiments as early as 1899, sold its first range of cars in 1905.  Success followed but so did troubles and by 1938, the company had been absorbed into the Nuffield organization.  Production continued but in the post-war years, Riley joined Austin, Morris, Wolseley and MG as part of the British Motor Corporation (BMC) conglomerate and the unique features of the brand began to disappear, the descent to the era of “badge engineering” soon complete.  The last Rileys were the Elf (a tarted-up Mini with a longer boot which was ascetically somehow wrong) and the Kestrel (a tarted-up Austin 1300), neither of which survived the great cull when BMC was absorbed by the doomed British Leyland, marque shuttered in 1969, never to return.  The rights to the Riley brand name are now held by BMW which has never even hinted there may be a revival, their unhappy (and costly) experience with Rover presumably a cautionary tale still told in Bavaria. 

Pre-war Riley Kestrels: 1938 1½ litre four-light Kestrel Sports Saloon (left), 1939 2½ litre Kestrel fixed head coupé (with post-war coachwork) (centre) and 1937 1½ litre 12/4 Kestrel Sprite Special Sports (right).

It was a shame because the pre-war cars in particular had been stylish and innovative, noted for an unusual form of valve activation which used twin camshafts mounted high in the block (thus not “overhead camshafts (OHC)”) which provided the advantages of short pushrods & optimized valve placement offered by the OHC arrangements without the weight and complexity.  Also of interest were their pre-selector transmissions, a kind of semi-automatic gearbox.  Among the most admired had been the 1½ & 2½ litre Kestrels (1934-1940), most of which wore built with saloon coachwork in four or six-light configurations although there were also fixed head (FHC) and drop head coupés (DHC) as well as a few special, lightweight roadsters.

The Kestrel Beer Company's "Flying Kestrel", built by Webster Race Engineering.

Of late, one 1935 Riley Kestrel has enjoyed an unusual afterlife.  In 2020, Scotland’s Kestrel Beer Company commissioned the UK’s Webster Race Engineering to create from one something to use as a land speed record (LSR) contender.  Dubbed “Flying Kestrel”, it’s powered by a turbocharged 2.5 litre (151 cubic inch) Audi TSI inline-five attached to an Audi A6 manual transmission, the power delivered to a Ford 9-inch differential, for decades a mainstay of drag-racing and anywhere else big power and torque needs to be handled.  After setting seven records during a 2021 campaign, the Flying Kestrel returned to Webster for fine-tuning including a new exhaust manifold, turbocharger blanket, and nitrous system for boost and cooling, a key gaol to reduce engine-bay heat.  On the dynamometer, the inline-five registered 991 horsepower (739 Kw) & 753 foot-pounds of torque (1022 Nm) and thus configured an attempt will be made on 17 June 2024 to achieve 200 (322 km/h).  LSR vehicles with much less power have often exceeded 200 mph but typically they have used bodywork with aerodynamic properties more obviously suited for the purpose.  It’s not clear if Webster’s Riley has been subject to much wind-tunnel testing but it may be assumed the shape is far from ideal as an LSR competitor and for some runs it has been fitted with rear fender skirts (spats), a trick in use since the 1920s.

Flying Kestrel with rear spats fitted during 2021 campaign.  Note the holes in the fenders which were added, not as a weight-saving measure (a la the frame of the Mercedes-Benz SSKL (1929-1932)) but to reduce lift at speed, the fenders tending otherwise to act as "parachutes".  The same technique was used by Zora Arkus-Duntov when trying to counter the alarming tendency of the front end of the Chevrolet Corvette Grand Sport (GS, 1962-1964) to "take off" as it approached 150 mph (240 km/h).  For reasons unrelated to aerodynamics, the GS programme proved abortive and of the planned run of 100-125 for homologation purposes, only five were built, all of which survived to become multi-million dollar collectables.      

The spats are one of the rare instances where adding weight increases speed, attested by the tests conducted during the 1930s by Mercedes-Benz and Auto-Union, both factories using spats front and rear on their LSR vehicles, extending the use to road cars although later Mercedes-Benz would admit the 10% improvement claimed for the 1937 540K Autobahn-kurier (highway cruiser) was just “a calculation” and it’s suspected even this was more guesswork than math.  Later, Jaguar’s evaluation of the ideal configuration to use when testing the 1949 XK120 (1948-1954) on Belgium roads revealed the rear spats added about 3-4 mph to top speed though they precluded the use of the lighter wire wheels and did increase the tendency of the brakes to overheat in severe use so, like many things in engineering, it was a trade-off.  More significantly perhaps, when travelling at speeds around 200 mph, “lift” is an issue and one which has afflicted many cars which have adhered well to the road at lower speeds.  Succinctly, the problem was in a 1971 interview explained by the General Motors’ (GM) engineer Zora Arkus-Duntov (1909-1996) who described the 1962-1967 (C2) Chevrolet Corvette as having “just enough lift to be a bad airplane.”  At speed, it’s another trade-off: the desire to lower aerodynamic drag versus the need for sufficient downforce for the tyres to remain sufficiently in contact with the earth’s surface for a driver to retain control, those few square inches of rubber the difference between life & death, especially at around 200 mph.  It’s hoped the “Flying Kestrel” proves a "windfucker" and lives up to the name figuratively, but not literally.

1935 Riley 1½ litre Kestrel (Chassis 22T 1238, Engine SL 4168) with custom coachwork (2004)

The intriguing mechanical specifications and the robust chassis has made the pre-war cars attractive candidates for re-bodying as an alternative to restoration.  Not all approve of such things (the originality police are humorless puritans as uncompromising as any Ayatollah) but some outstanding coachwork has been fashioned, almost always the result of converting a saloon or limousine to a coupé, convertible or roadster.  The 1935 1½ litre Kestrel above began life as a four-door saloon which was converted to a DHC during 2004 and the lines have been much-admired, recalling (obviously at a smaller scale) some of the special-bodied Mercedes-Benz SS (1928-1933), the more ostentatious of the larger Buccialis (1928-1933) and the Bugatti Royale (1927-1933).

A kestrel windfucking.
