Quartervent

Quartervent (pronounced kwawr-ter-vent)

A small, pivoted, framed (or semi-framed) pane in the front or rear side-windows of a car, provided to optimize ventilation.

1930s: The construct was quarter + vent.  Dating from the late thirteenth century, the noun quarter (in its numerical sense) was from the Middle English quarter, from the Anglo-Norman quarter, from the Old French quartier, from the Latin quartarius (a Roman unit of liquid measure equivalent to about 0.14 litre).  Quartus was from the primitive Indo-European kweturtos (four) (from which the Ancient Greek gained τέταρτος (tétartos), the Sanskrit चतुर्थ (caturtha), the Proto-Balto-Slavic ketwirtas and the Proto-Germanic fedurþô).  It was cognate to quadrus (square), drawn from the sense of “four-sided”.  The Latin suffix –arius was from the earlier -ās-(i)jo- , the construct being -āso- (from the primitive Indo-European -ehso- (which may be compared with the Hittite appurtenance suffix -ašša-) + the relational adjectival suffix -yós (belonging to).  The suffix (the feminine –āria, the neuter -ārium) was a first/second-declension suffix used to form adjectives from nouns or numerals.  The nominative neuter form – ārium (when appended to nouns), formed derivative nouns denoting a “place where stuff was kept”.  The Middle English verb quarteren, was derivative of the noun.  Dating from the mid fourteenth century, vent was from the Middle English verb venten (to furnish (a vessel) with a vent), a shortened form of the Old French esventer (the construct being es- + -venter), a verbal derivative of vent, from the Latin ventus (wind), in later use derivative of the English noun.  The English noun was derived partly from the French vent, partly by a shortening of French évent (from the Old French esvent, a derivative of esventer) and partly from the English verb.  The hyphenated form quarter-vent is also used and may be preferable.  Quarter-vent is a noun; the noun plural is quarter-vents.  In use, the action of using the function provided by a quarter-vent obviously can be described with terms like quarter-venting or quarter-vented but no derived forms are recognized as standard.

1959 Cadillac Eldorado Biarritz.

Like almost all US passenger cars, the post-war Cadillacs all had quarter-vents (“vent windows” or “ventiplanes” to the Americans) and on the most expensive in the range they were controlled by an electric motor, a feature optional on the lesser models.  This was a time when the company's slogan Standard of the World” really could be taken seriously.  In 1969, with General Motors (GM) phasing in flow-through ventilation, Cadillac deleted the quarter-vents, meaning purchasers no longer had to decide whether to pay the additional cost to have them electrically-activated (a US$71.60 option on the 1968 Calais and De Ville).  GM's early implementation of flow-through ventilation was patchy so the change was probably premature but by 1969 the system was perfected and as good as their air-conditioning (A-C), famous since the 1950s for its icy blast.    

The now close to extinct quarter-vents were small, pivoted, framed (or semi-framed) panes of glass installed in the front or rear side windows of a car or truck; their purpose was to provide occupants with a source of ventilation, using the air-flow of the vehicle while in motion.  The system had all the attributes of other admirable technologies (such as the pencil) in that it was cheap to produce, simple to use, reliable and effective in its intended purpose.  Although not a complex concept, GM in 1932 couldn’t resist giving the things an impressively long name, calling them “No Draft Individually Controlled Ventilation” (NDICV being one of history’s less mnemonic initializations).  GM’s marketing types must have prevailed because eventually the snappier “ventiplanes” was adopted, the same process of rationality which overtook Chrysler in 1969 when the public decided “shaker” was a punchier name for their rather sexy scoop which, attached directly to the induction system and, protruding through a carefully shape lacuna in the hood (bonnet), shook with the engine, delighting the males aged 17-39 to whom it was intended to appeal.  “Shaker” supplanted Chrysler’s original “Incredible Quivering Exposed Cold Air Grabber” (IQECAG another dud); sometimes less is more.  Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) suggested a good title for his book might be Viereinhalb Jahre [des Kampfes] gegen Lüge, Dummheit und Feigheit (Four and a Half Years of Struggle against Lies, Stupidity and Cowardice) but his publisher thought that a bit ponderous and preferred the more succinct Mein Kampf: Eine Abrechnung (My Struggle: A Reckoning) and for publication even that was clipped to Mein Kampf.  Unfortunately, the revised title was the best thing about it, the style and contents truly ghastly and it's long and repetitious, the ideas within able easily to be reduced to a few dozen pages (some suggest fewer but the historical examples cited for context do require some space).

The baroque meets mid-century modernism: 1954 Hudson Italia by Carrozzeria Touring.  

Given how well the things worked, there’s long been some regret at their demise, a process which began in the 1960s with the development of “through-flow ventilation”, the earliest implementation of which seems to have appeared in the Hudson Italia (1954-1955), an exclusive, two-door coupé co-developed by Hudson in Detroit and the Milan-based Italian coachbuilder Carrozzeria Touring.  Although some of the styling gimmicks perhaps haven’t aged well, the package was more restrained than some extravagances of the era and fundamentally, the lines were well-balanced and elegant.  Unfortunately the mechanical underpinnings were uninspiring and the trans-Atlantic production process (even though Italian unit-labor costs were lower than in the US, Touring’s methods were labor-intensive) involved two-way shipping (the platforms sent to Milan for bodies and then returned to the US) so the Italia was uncompetitively expensive: at a time when the bigger and more capable Cadillac Coupe de Ville listed at US$3,995, the Italia was offered for US$4,800 and while it certainly had exclusivity, it was a time when there was still a magic attached to the Cadillac name and of the planned run of 50, only 26 Italias were produced (including the prototype).  Of those, 21 are known still to exist and they’re a fixture at concours d’élégance (a sort of car show for the rich, the term an un-adapted borrowing from the French (literally “competition of elegance”) and the auction circuit where they’re exchanged between collectors for several hundred-thousand dollars per sale.  Although a commercial failure (and the Hudson name would soon disappear), the Italia does enjoy the footnote of being the first production car equipped with what came to be understood as “flow-through ventilation”, provided with a cowl air intake and extraction grooves at the top of the rear windows, the company claiming the air inside an Italia changed completely every ten minutes.  For the quarter-vent, flow-through ventilation was a death-knell although some lingered on until the effective standardization of A-C proved the final nail in the coffin.

1965 Ford Cortina GT with eyeball vents and quarter-vents.

The car which really legitimized flow-through ventilation was the first generation (1962-1966) of the Ford Cortina, produced over four generations (some claim it was five) by Ford’s UK subsidiary between 1962-1982).  When the revised model displayed at the Earls Court Motor Show in October 1964, something much emphasized was the new “Aeroflow”, Ford’s name for through-flow ventilation, the system implemented with “eyeball” vents on the dashboard and extractor vents on the rear pillars.  Eyeball vents probably are the best way to do through-flow ventilation but the accountants came to work out they were more expensive to install than the alternatives so less satisfactory devices came to be used.  Other manufacturers soon phased-in similar systems, many coining their own marketing trademarks including “Silent-Flow-Ventilation”, “Astro-Ventilation” and the inevitable “Flow-thru ventilation”.  For the Cortina, Ford took a “belt & braces” approach to ventilation, retaining the quarter-vents even after the “eyeballs” were added, apparently because (1) the costs of re-tooling to using a single pane for the window was actually higher than continuing to use the quarter-vents, (2) it wasn’t clear if there would be general public acceptance of their deletion and (3) smoking rates were still high and drivers were known to like being able to flick the ash out via the quarter-vent (and, more regrettably, the butts too).  Before long, the designers found a way economically to replace the quarter-vents with “quarter-panes” or “quarter-lights” (a fixed piece of glass with no opening mechanism) so early Cortinas were built with both although in markets where temperatures tended to be higher (notable South Africa and Australia), the hinged quarter-vents remained standard equipment.  When the Mark III Cortina (TC, 1970-1976) was released, the separate panes in any form were deleted and the side glass was a single pane.

Fluid dynamics in action: GM's Astro-Ventilation.

So logically a “quarter-vent” would describe a device with a hinge so it could be opened to provide ventilation while a “quarter-pane”, “quarter-light” or “quarter-glass” would be something in the same shape but unhinged and thus fixed.  It didn’t work out that way and the terms tended to be used interchangeably (though presumably “quarter-vent” was most applied to those with the functionality.  However, the mere existence of the fixed panes does raise the question of why they exist at all.  In the case or rear doors, they were sometimes a necessity because the shape of the door was dictated by the intrusion of the wheel arch and adding a quarter-pane was the only way to ensure the window could completely be wound down.  With the front doors, the economics were sometimes compelling, especially in cases when the opening vents were optional but there were also instances where the door’s internal mechanisms (the door opening & window-winding hardware) were so bulky the only way to make stuff was to reduce the size of the window.  In some cases, manufacturers "solved" the problem by making rear side glass fixed which lowered their costs but it was never popular with customers.

1976 Volkswagen Passat B1 (1973-1980 (1988 in Brazil)) without quarter-vents, the front & rear quarter-panes fixed.

The proliferation of terms could have come in handy if the industry had decided to standardize and the first generation Volkswagen Passat (1973-1980) was illustrative of how they might been used.  The early Passats were then unusual in that the four-door versions had five separate pieces of side glass and, reading from left-to-right, they could have been classified thus: (1) a front quarter-pane, (2) a front side-window, (3) a rear side-window, (4) a rear quarter-pane and (5) a quarter-window.  The Passat was one of those vehicles which used the quarter-panes as an engineering necessity to permit the rear side-window fully to be lowered.  However the industry didn’t standardize and in the pre-television (and certainly pre-internet) age when language tended to evolve with greater regional variation, not even quarter-glass, quarter-vent, quarter-window & quarter-pane were enough and the things were known variously also as a “fly window”, “valence window”, “triangle window” and (possibly annoying architects) “auto-transom”, the hyphen used and not.

PA Vauxhall Velox (1957-1962): 1959 (left) and 1960 (right).  The one-piece rear window was introduced as a running-change in late 1959.

Before flow-through ventilation systems and long before A-C became ubiquitous, quarter-vents were the industry standard for providing airflow to car interiors and it was common for them to be fitted on both front and rear-doors and frequently, the rear units were fixed quarter-panes (the lowering of the side window thing).  A special type of fixed quarter-pane were those used with rear windows, originally an economic imperative because initially it was too expensive to fabricate one piece glass to suit the “wrap-around styles becoming popular.  Improved manufacturing techniques let the US industry by the early 1950s overcome the limitations but elsewhere, the multi-piece fittings would continue to be used for more than a decade.

1957 Mercury Turnpike Cruiser (left), details of the apparatuses above the windscreen (centre) and the Breezeaway rear window lowered (right)

The 1957 Mercury Turnpike Cruiser was notable for (1) the truly memorable model name, (2) introducing the “Breezeway" rear window which could be lowered and (3) having a truly bizarre arrangement of “features” above the windscreen.  Unfortunately, the pair of “radio aerials” protruding from the pods at the top of the Mercury’s A-pillars were a mere affectation, a “jet-age” motif decorating what were actually air-intakes.

A three-piece construction was however adopted as part of the engineering for the “Breezeway”, a retractable rear window introduced in 1957 on the Mercury Turnpike Cruiser.  It was at the time novel and generated a lot of publicity but the concept would have been familiar to those driving many roadsters and other convertibles which had “zip-out” rear Perspex screens, allowing soft-top to remain erected while the rear was open.  Combined with the car’s quarter-vents, what this did was create the same fluid dynamics as flow-through ventilation.  The way Mercury made the retractable glass work was to section the window in a centre flat section (some 80% of the total width), flanked by a pair of fixed quarter-panes.  After the run in 1957-1959, it was resurrected for use on certain Mercury Montclairs, Montereys and Park Lanes.

1958 (Lincoln) Continental Mark III Convertible (with Breezeway window).  The platform was unitary (ie no traditional chassis) which with modern techniques easily was achievable on the sedans and coupes but the convertible required so much additional strengthening (often achieved by welding-in angle iron) that a Mark III Convertible, fueled and with four occupants, weighed in excess of 6000 lb (2720 kg). 

Ford must have been much taken with the feature because it appeared also on the gargantuan “Mark” versions of the (Lincoln) Continentals 1958, 1959 & 1960, dubbed respectively Mark III, IV, & V, designations Ford shamelessly would begin to recycle in 1969 because the corporation wanted the new Mark III to be associated with the old, classic Continental Mark II (1956-1957) rather than the succeeding bloated trio.  The “Breezeway” Lincolns also featured a reverse-slanted rear window, something which would spread not only to the Mercurys of the 1960s but also the English Ford Anglia (105E, 1959-1968) and Consul Classic (1961-1963) although only the US cars ever had the retractable glass.  The severe roofline was used even on the convertible Continentals, made possible by them sharing the rear window mechanism used on the sedan & couple, modified only to the extent of being retractable into a rear compartment.

1974 Lincoln Continental Town Car with mini vents.

In the 1970s Lincoln introduced the novelty of “mini-vents” which raised and lowered separately from the main side-glass.  Smoking was at the time socially acceptable (in some circles it must have appeared obligatory) and there was a lot of it about so engineers devoting time to finding a better way for those wanting to “flick ash out the window” while running the A-C wasn’t surprising.  Those visualizing a “flick” in process might be surprised such a thing existed because if in a modern vehicle, its shape honed in wind-tunnels and computer simulations, what would likely happen would be “blowback”.  That’s because the shape is aerodynamically efficient (with a “buffer zone” very close to the surface) and disrupting that by lowering a window shifts the inside pressure from positive to negative, ask thus being “sucked-in”.  However, on something like a 1974 Lincoln Continental (which conceptually can be imagined as one brick sitting atop two), the buffer zone can (depending on speed) extend as as much as 3 feet (close to a metre) from the body.  The meant ash was flicked into the “buffer zone” and it didn’t end up back in the cabin.  The vents didn’t last (another casualty of the quest for lower drag) but as late as 1985 they appeared as a US$72 extra and were known in the industry as the “smoker's option”.

Through Chevrolet's COPO (Central Office Production Order) system, 69 1969 Camaros were built with the ZL1, an all-aluminum version of the 427 cubic inch (7.0 litre) big-block V8.  The COPO had been established as an efficient way to coordinate the production of fleet orders (law enforcement agencies, utility companies etc) for runs of vehicles in a certain specification but the drag racing community and others worked out it could be used also as “back-door” way to order small runs of cars with otherwise unavailable high-performance engines.  The Freakier Friday Camaro (badged as a 396 SS but several were used during filming including at least one with a roll-over bar for the stunt work) lacks the vent windows which were deleted from the range after 1967 when “Astro-Ventilation” (GM’s name for flow-through ventilation) was added.  In North American use, the devices typically are referred to as “vent windows” while a “quarter light” is a small lamp mounted (in pairs) in the lower section of the front bodywork and a “quarter-vent” is some sort of (real or fake) vent installed somewhere on the quarter panels.  As flow-through ventilation became standardized and A-C installation rates rose, Detroit abandoned the quarter-vent which pleased industry because it eliminated both parts and labor, lowering the cost of production (the savings absorbed as profits rather than being passed to the customers).  On the small, cheap Ford Pinto (1971-1980), removing the feature saved a reported US$2.16 per unit but, being small and cheap, A-C rarely was ordered by Pinto buyers which was probably a good thing because, laboring under the 1970s burdens of emission controls, the weight of  impact-resistant bumper bars and often an automatic transmission a Pinto was lethargic enough with out adding power-sapping A-C compressor and plumbing.  Responding (after some years of high inflation) to dealer feedback about enquires from Pinto customers indicating a interest in the return of vents, Fords cost-accountants calculated the unit cost of the restoration would be some US$17.  

Ford Australia’s early advertising copy for the XA Falcon range included publicity shots both with and without the optional quarter-vents (left) although all sedans & station wagons had the non-opening, rear quarter-panes, fitted so the side window completely could be lowered.  One quirk of the campaign was the first shot released (right) of the “hero model” of the range (the Falcon GT) had the driver’s side quarter-vent airbrushed out (how “Photoshop jobs” used to be done), presumably because it was thought to clutter a well-composed picture.  Unfortunately, the artist neglected to defenestrate the one on the passenger’s side.

Released in Australia in March 1972, Ford’s XA Falcon was the first in the lineage to include through-flow ventilation, the previously standard quarter-vent windows moved to the option list (as RPO (Regular Production Option) 86).  Because Australia often is a hot place and many Falcons were bought by rural customers, Ford expected a high take-up rate of RPO 86 (it was a time when A-C was expensive and rarely ordered) so the vent window hardware was stockpiled in anticipation.  However, the option didn’t prove popular but with a warehouse full of the parts, they remained available on the subsequent XB (1973-1976) and XC (1976-1979) although the take-up rate never rose, less the 1% of each range so equipped and when the XD (1979-1983) was introduced, there was no such option and this continued on all subsequent Falcons until Ford ceased production in Australia in 2016, by which time A-C was standard equipment.

Great moments in tabloid journalism: Sydney's Sun-Herald, Sunday 25 June, 1972.  The Sun-Herald was then part of the Fairfax group, proving Rupert Murdoch (b 1931) can't be blamed for everything.

The infrequency with which RPO 86 was ordered has been little noted by history but on one car with the option the fixtures did become a element which enabled a owner to claim the coveted “one-of-one” status.  In August 1973, near the end of the XA’s run, with no fanfare, Ford built about 250 Falcons with RPO 83, a bundle which included many of the parts intended for use on the stillborn GTHO Phase IV, cancelled (after four had been built) in 1972 after a newspaper generated one of their moral panics, this time about the “160 mph super cars” it was claimed the local manufacturers were about to unleash and sell to males ages 17-25.  Actually, none of them were quite that fast but not often has the tabloid press been too troubled by facts and the fuss spooked the politicians (it's seldom difficult to render a "minister horrified").  Under pressure, Holden cancelled the LJ Torana V8, Ford the GTHO Phase IV and Chrysler reconfigured it's E55 Charger 340 as a luxury coupé, available only with an automatic transmission and no high-performance modifications.

The “quarter-vent XA RPO 83 GT”: 1973 Ford Falcon XA GT sedan (Body Identification: 54H; Model Code: 18238) in Calypso Green (code J) with Onyx Black (code B) accents over Black Vinyl (Code B) with 351 4V V8 (Code T) and four-speed manual transmission (Code L).  It’s the only one produced with both RPO 83 (a (variably fitted) bundle of parts left-over from the aborted GTHO Phase IV project) and RPO 86 (front quarter-vent windows).  In the collector market they're referred to usually as “the RPO83 cars”.

So in 1973 Ford's warehouse still contained all the parts which were to be fitted to the GTHO Phase IV so they’d be homologated for competition and although the rules for racing had been changed to ensure there was no longer any need to produce small batches of “160 mph (257 km/h) super cars”, Ford still wanted to be able to use the heavy-duty bits and pieces in competition so quietly conjured up RPO 83 and fitted the bundle on the assembly line, most of the cars not earmarked for allocation to racing teams sold as “standard” Falcon GTs.  Actually, it’s more correct to say “bundles” because while in aggregate the number of the parts installed was sufficient to fulfil the demands of homologation, not all the RPO 83 GTs received all parts so what a buyer got really was “luck of the draw”; with nobody being charged extra for RPO 83, Ford didn’t pay too much attention to the details of the installations and many who purchased one had no idea the parts had been included, the manual choke's knob the only visually obvious clue.  Ford made no attempt to publicize the existence of RPO 83, lest the tabloids run another headline.  It’s certain 250 RPO 83 cars were built (130 four-door sedans & 120 two-door Hardtops) but some sources say the breakdown was 131 / 121 while others claim an addition nine sedans were completed.  Being a genuine RPO 83 car, the Calypso Green GT attracts a premium and while being only RPO 83 with quarter-vent windows is not of any great significance, it does permit the prized “one-of-one” claim and not even any of the four GTHO Phase IVs built (three of which survive) had them.  In the collector market, the “one-of-one” status can be worth a lot of money (such as a one-off convertible in a run of coupés) but a Falcon’s quarter-vents are only a curiosity.

All else being equal, what makes one RPO83 more desirable than another is if it was factory-fitted with all the option's notional inventory and most coveted are the ones with four-wheel disk brakes.  Because the project was focused on the annual endurance event at Bathurst's high-speed Mount Panorama circuit, the disks were as significant as an additional 50 horsepower and a few weeks before the RPO 83 run they'd already been fitted to the first batch of Landaus, which were Falcon Hardtops gorped-up (what bling used to be called) with hidden headlights, lashings of leather, faux woodgrain and a padded vinyl roof, all markers of distinction in the 1970s and, unusually, there was also a 24 hour analogue clock.  Essentially a short wheelbase, two-door LTD (which structurally was a Falcon with the wheelbase stretched 10 inches (250 mm) to 121 (3075 mm)), the Landau was not intended for racetracks but because it shared a body shell and much of the running gear with the Falcon GT Hardtops, Ford claimed Landau production counted towards homologation of the rear disks.  Fearing that might be at least a moot point, a batch were installed also on some of the RPO83 cars and duly the configuration appeared at Bathurst for the 1973 event, their presence of even greater significance because that was the year the country switched from using imperial measures to metric, prompting the race organizers to lengthen the race from 500 miles (804 km) to 625 (1000), the Bathurst 500 thus becoming the Bathurst 1000.  RPO83 Falcon GTs won the 1973 & 1974 Bathurst 1000s.

The “quarter-vent XB GT”: 1973 Ford Falcon XB GT sedan (Body Identification: 54H; Model Code: 18338) in Polar White (Code 3) with Onyx Black (code B) accents over Parchment Vinyl (Code P) with 351C 4V V8 (Code T) and four-speed manual transmission (Code L).  The only one produced with RPO 86 (front quarter-vent windows).

So with a large stock sitting in the warehouse, despite the dismally low take-up rate, the quarter-vents remained available when the XB Falcon (1973-1976) range was released and of the 1952 XB GT sedans sold (there were also 949 two-door Hardtops) a single buyer ticked the RPO 86 box.  Again, although granting the coveted “one-of-one” status, it’s not something of great significance although the car to which the pair of vents was fitted is one of the more desirable XB GTs because it was one of the 139 XB GTs built with the combination of the “4V Big Port” 351 V8 and four-speed Top Loader manual transmission.  The first 211 XB GTs received the fully-imported 351 Clevelands, “using up” what was in stock, subsequent models switching to the locally made variant.

US Built 351C-4V in 1973 XB Falcon GT.

Ford Australia had been importing from the US the high-performance 351C-4V (4 venturi (ie two-barrel carburetor) V8 for use in the GT but when advised US production of that configuration was ending, the decision was taken to produce a local “high-performance” version of the 351 using the 351C 2V “small port” cylinder heads with “open” combustion chambers and a four-barrel carburetor; Ford Australia only ever manufactured the “small port” heads.  That means the Australian nomenclature “351C-4V” (small ports & four barrel carburetor) differs in meaning from that used in the US where it translated to “big ports & four barrel carburetor”.  It sounded a retrogressive step and while there was some sacrifice in top-end power, the antipodean combo turned out to be ideal for street use because the fluid dynamics of the flow rate through the smaller ports made for better low and mid-range torque (most useful for what most drivers do most of the time) whereas the big-port heads really were optimized for full-throttle operation, something often done on race tracks but rarely on public roads… even in the Australia of the early 1970s.  Still, some did miss the responsiveness of the high-compression US-built engine, even if the difference was really apparent only above 80 mph (130 km/h).

The other ceremony which happened in Australia on 11 November, 1975: Ford Australia's photo shoot, Melbourne, Victoria.

Although only 2,901 XB GTs were produced, as the “halo” model it was an important image-maker and the XB range proved successful with almost 212,000 sold over its 34 month life (over 18 months in a generally more buoyant economy XA production had reached over 129,000).  Stylistically, the XB was an improvement over the poorly detailed XA and much was made (among Fords claimed 2,056 changes from the XA) of the headlight’s high-beam activation shifting from a foot-operated button to a steering column stalk which, thirty-odd years on from the achievement of nuclear fission, doesn’t sound like much but motoring journalists had for years been advocating for “a headlight flasher” having been impressed by the “safety feature” when being “flashed” on the German Autobahns by something about to pass at high speed.  More welcome still was the GT’s four-wheel disk brakes, acknowledged as good as any then in volume production.  The success of the XB coincided with Ford Australia’s two millionth vehicle leaving the assembly line so on Tuesday 11 November, 1975, Ford’s public relations office invited journalists and camera crews to a ceremony to mark the occasion, laying on the usual catering (including free cigarettes!) to ensure a good attendance.

Ford Australia pre-release publicity shot for the XB range release (embargoed until 15 September 1973).

1973 Ford Falcon XB GT Hardtop (Body Identification: 65H; Model Code: 18318) in Yellow Blaze (Code M) with Onyx Black (code B) accents over Black Vinyl (Code B) with 351C 4V V8 (Code T) and three-speed T-Bar automatic transmission (Code B).  Because the various side windows used by the Hardtop, Ute and Panel Van derivatives were different to fit the door and roof shapes, the quarter-vents were never offered on those and RPO 86 on the Hardtops was the dreaded vinyl roof in tan.  The sunroof (RPO 10) was a rarely (168 Falcons and 244 Fairmonts) specified option.

Unfortunately, the pictures of the dutifully polished XB Fairmont (a Falcon with some gorp) sedan didn’t generate the publicity expected because the next editions of the daily newspapers (there were then a lot of those and they sold in big numbers) had a more sensational story to cover: On that Tuesday Sir John Kerr (1914–1991; governor-general of Australia 1974-1977) had dismissed from office Gough Whitlam (1916–2014; prime minister of Australia 1972-1975) and his troubled administration.  It was the first time the Crown had sacked a prime-minister since William IV (1765–1837; King of the UK 1830-1837) in 1834 dismissed Lord Melbourne (1779–1848; prime minister of the UK 1834 & 1835-1841) and although in 1932 Sir Philip Game (1876–1961; governor of NSW 1930-1935) had sundered the commission of Jack Lang (1876–1975; premier of New South Wales 1925-1927 & 1930-1932), most Australians who pondered such things believed the days of meddling viceroys were done.  Sir John however proved the royal prerogative still existed (although paradoxically perhaps now only in the hands of a monarch’s representative rather than their own) and the footnote in the history of Australian manufacturing passed almost unnoticed.

1969: An irregular formation of quadra, a variant (like quadru) from the older Latin form quadri- (four) + phonic from the Ancient Greek phonē (sound, voice).  All the Latin forms were related quattor (four) from the primitive Indo-European kwetwer (four).  Phonē was from the primitive Indo-European bha (to speak, tell, say) which was the source also of the Latin fari (to speak) and fama (talk, report).  Phonic, as an adjective in the sense of “pertaining to sound; acoustics" was used in English as early as 1793. Those for whom linguistic hygiene is a thing approved not at all of quadraphonic because it was a hybrid built from Latin and Greek.  They preferred either the generic surround sound which emerged later or the pure Latin lineage of quadrasonic (sonic from sonō (make a noise, sound)) which appeared as early as 1970 although it seems to have been invented as a marketing term rather than by disgruntled pedants.  Quadraphonic, quadrasonic and surround sound all refer to essentially the same thing: the reproduction of front-to-back sound distribution in addition to side-to-side stereo.  In live performances, this had been done for centuries and four-channel recording, though not mainstream, was by the 1950s, not uncommon.  Quadraphonic is and adjective but had been used as a noun; the (equally irregular) noun plural is quadraphonics.

Surround sound

Quadraphonic was an early attempt to mass-market surround sound.  It used four sound channels with four physical speakers intended to be positioned at the four corners of the listening space and each channel could reproduce a signal, in whole or in part, independent of the others.  It was briefly popular with manufacturers during the early 1970s, many of which attempted to position it as the successor to stereo as the default standard but consumers were never convinced and quadraphonic was a commercial failure, both because of technical issues and the multitude of implementations and incompatibilities between systems; many manufacturers built equipment to their own specifications and no standard was defined, a mistake not repeated a generation later with the CD (compact disc).  Nor was quadraphonic a bolt-on to existing equipment; it required new, more expensive hardware.

Quadraphonic audio reproduction from vinyl was patchy and manufacturers used different systems to work around the problems but few were successful and the physical wear of vinyl tended always to diminish the quality.  Tape systems also existed, capable of playing four or eight discrete channels and released in reel-to-reel and 8-track cartridge formats, the former more robust but never suited to the needs of mass-market consumers.  The rise of home theatre products in the late 1990s resurrected interest in multi-channel audio, now called “surround sound” and most often implemented in the six speaker 5.1 standard.  Modern electronics and the elimination of vinyl and tape as storage media allowed engineers to solve the problems which beset quadraphonic but there remain audiophiles who insist, under perfect conditions, quadraphonic remains the superior form of audio transmission for the human ear.

First commercially available in 1965, the eight-track cartridge format (which would later become the evil henchman of quadraphonic) convinced manufacturers it was the next big thing and they rushed to mass-production and one genuine reason for the appeal was that the 8-track cartridge was the first device which was practical for use as in-car entertainment.  During the 1950s, the US car industry had offered the option of record players, neatly integrated into the dashboard and in the relatively compact space of a vehicle's interior, the sound quality could be surprisingly high.  Although not obviously designed with acoustic properties optimized for music, the combination of parallel flat surfaces, a low ceiling and much soft, sound absorbing material did much to compensate for the small size and range offered by the speakers.  However, although they worked well when sitting still in showroom or in certain vehicles, on the road things could be different.  The records (the same size as the classic 7 inch (180 mm) 45 rpm "singles") played by means of a stylus (usually called "the needle") which physically traced the grooves etched into the plastic disks rotating at 16.66 rpm which, combined with an etching technique called "ultra micro-grooving" meant the some 45 minutes of music were available, a considerable advance on the 4-5 minutes of the standard single.  The pressings were also thicker than other records, better to resist the high temperatures caused by heat-soak from the engine and the environment although, in places like Arizona, warping was soon reported.  To keep the stylus in the track, the units were fitted with a shock-absorbing, spring enclosure and a counterweighted needle arm.  Improbably, in testing, the system performed faultlessly even under the most adverse road conditions so the designers presented the product for corporate approval.  At that point there was a delay because the designers worked for the Colombia Broadcasting Corporation (CBS) which had affiliations with thousands of radio stations all over the country and no wish to cannibalize their own markets; if people could play records in their cars, the huge income stream CBS gained from advertising would be threatened as drivers tuned out.  The proposal was rejected.

Discouraged but not deterred, the engineers went to Detroit and demonstrated the players to Chrysler which had their test-drivers subject the test vehicles to pot-holes, railway tracks and rolling undulations.  The players again performed faultlessly and Chrysler, always looking for some novelty, placed an order for 18,000, a lucrative lure which convinced even CBS to authorize production, their enthusiasm made all the greater by the proprietary format of the disks which meant CBS would be the exclusive source.  So, late in 1956, Chrysler announced the option of "Highway Hi-Fi", a factory-installed record player mounted under the car's dashboard at a cost of (US$200 (some US$1750 in 2023 terms)).  Highway Hi-Fi came with six disks, the content of which reflected the reactionary tastes of CBS executives and their desire to ensure people still got their popular music from radio stations but the market response was positive, Chrysler selling almost 4000 of the things in their first year, the early adopters adopting with their usual alacrity.

The second generation of players used standard 45 rpm singles: Austin A55 Farina (left) and George Harrison's (1943–2001) Jaguar E-Type S1 (right); all four Beatles had the players fitted in their cars and lead guitarist Harrison is pictured here stocking his 14-stack array.  The lady on the left presumably listened to different music than the Beatle on the right (although their in-car hardware was identical) but tastes can't always be predicted according to stereotype; although he disapproved of most modern music, Rudolf Hess (1894–1987; Nazi deputy Führer 1933-1941) told the governor of Spandau prison (where he spent 40 of his 46 years in captivity) he enjoyed The Beatles because their tunes "were melodic".  

At that point, problems surfaced.  Tested exclusively in softly-sprung, luxury cars on CBS's and Chrysler's executive fleets, the Highway Hi-Fi had to some extent been isolated from the vicissitudes of the road but when fitted to cheaper models with nothing like the same degree of isolation, the styluses indeed jumped around and complaints flowed, something not helped by dealers and mechanics not being trained in their maintenance; even to audio shops the unique mechanism was a mystery.  Word spread, sales collapsed and quietly the the option was withdrawn in 1957.  The idea however didn't die and by the early 1960s, others had entered the field and solved most of the problems, disks now upside-down which made maintaining contact simpler and now standard 45 rpm records could be used, meaning unlimited content and the inherent limitation of the 4 minute playing time was overcome with the use of a 14-disk stacker, anticipating the approach taken with CDs three decades later.  Chrysler tried again by the market was now wary and the option was again soon dropped.

Clearly though, there was demand for in-car entertainment, the content of which was not dictated by radio station programme directors and for many there were the additional attractions of not having to endure listening either to advertising or DJs, as inane then as now.  It was obvious to all tape offered possibilities but although magnetic tape recorders had appeared as early as 1930s, they were bulky, fragile complicated and expensive, all factors which mitigated against their use as a consumer product fitted to a car.  Attention was thus devoted to reducing size and complexity so the tape could be installed in a removable cartridge and by 1963, a consortium including, inter alia, Lear, RCA, Ford & Ampex had perfected 8-track tape which was small, simple, durable and able to store over an hour of music.  Indeed, so good was the standard of reproduction that to take advantage of it, it had to be connected to high quality speakers with wiring just as good, something which limited the initial adoption to manufacturers such as Rolls-Royce and Cadillac or the more expensive ranges of others although Ford's supporting gesture late in 1965 of offering the option on all models was soon emulated.  Economies of scale soon worked its usual wonders and the 8-track player became an industry standard, available even in cheaper models and as an after-market accessory, some speculating the format might replace LP records in the home.

That never happened although the home units were widely available and by the late 1960s, the 8-track was a big seller for all purposes where portability was needed.  It maintained this position until the early 1970s when, with remarkable suddenness, it was supplanted the the cassette, a design dating from 1962 which had been smaller and cheaper but also inferior in sound delivery and without the broad content offered by the 8-track supply system.  That all changed by 1970 and from that point the 8-track was in decline, reduced to a niche by late in the decade, the CD in the 1980s the final nail in the coffin although it did for a while retain an allure, Jensen specifying an expensive Lear 8-track for the Interceptor SP in 1971, despite consumer reports at the time confirming cassettes were now a better choice.  The market preferring the cheaper and conveniently smaller cassette tapes meant warehouses were soon full of 8-track players and buyers were scarce.  In Australia, GMH (General Motor Holden) by 1975 had nearly a thousand in the inventory which also bulged with 600-odd Monaro body-shells, neither of which were attracting customers.  Fortunately, GMH was well-acquainted with the concept of the "parts-bin special" whereby old, unsaleable items are bundled together and sold at what appears a discount, based for advertising purposes on a book-value retail price there’s no longer any chance of realizing.

1976 Holden HX LE

Thus created was the high-priced, limited edition Holden LE (not badged as a Monaro although it so obviously looked like one that they've never been known as anything else), in "LE Red" (metallic crimson) with gold pin-striping, Polycast "Honeycomb" wheels, fake (plastic) burl walnut trim, deep cut-pile (polyester) carpet and crushed velour (polyester) upholstery with plaid inserts over vinyl surrounds in matching shades; in the 1970s, this was tasteful.  Not exactly suited to the image of luxury were the front and rear spoilers but they too were sitting unloved in the warehouse so they became part of the package and, this being the 1970s, rear-seat occupants got their own cigar lighter, conveniently located above the central ashtray.  Not designed for the purpose, the eight-track cartridge player crudely was bolted to the console but the audio quality was good and five-hundred and eighty LEs were made, GMH pleasantly surprised at how quickly they sold.  When new, they listed at Aus$11,500, a pleasingly profitable premium of some 35% above the unwanted vehicle on which it was based.  These days, examples are advertised for sale for (Aus$) six-figure sums but those who now buy a LE do so for reasons other than specific-performance.  Although of compact size (in US terms) and fitted with a 308 cubic inch (5.0 litre) V8, it could achieve barely 110 mph (175 km/h), acceleration was lethargic by earlier and (much) later standards yet fuel consumption was very high; slow and thirsty the price to be paid for the early implementations of the emission control devices bolted to engines designed during more toxic times.

1976 Holden HX LE Polycast "Honeycomb" wheel (14 x 7").

The Polycast process used a conventional steel wheel with a decorative face of molded polyurethane, attached with mechanical fasteners or bonded using adhesives (in some, both methods were applied) and although some snobs still call them "fake alloy" wheels, legitimately, they're a category of their own.  Because the rubbery, molded plastic fulfilled no structural purpose, designers were able to create intricate shapes which would then have been too delicate or complex to render (at an acceptable cost) in any sort of metal.  By consensus, some of the Ploycast wheels were among the best looking of the decade and, unstressed, they were strong, durable and long-lasting while the manufacturers liked them because the tooling and production costs were much lower than for aluminium or magnesium-alloy.  Another benefit was, being purely decorative (essentially a permanently attached wheelcover), their use faced no regulatory barriers; US safety rules were even then strict and Citroën at the time didn't both seeking approval for the more exotic "resin" wheels offered in Europe on the SM).

Aftermath of the pace car crash, Indianapolis 500, 29 May 1971; dozens were injured but there were no fatalities, despite impact with the well-populated camera stand being estimated at 60 mph (100 km/h).

The Holden LE's wheels came straight from the Pontiac parts bin in the US where they'd first appeared on the 1971 Firebird Trans-Am.  The concept proved popular with manufacturers and a set of Motor Wheels' "Exiter" (14" x 7", part number 36830 and advertised also as "Exciter") was fitted to the Dodge Challenger Pace car which crashed during the 1971 Indianapolis 500.  The crash was unrelated to the wheels, the driver (one of the Dodge dealers providing the pace car fleet) blaming the incident on somebody moving the traffic cone he'd used in practice as his pit-lane braking marker.    Motor Wheel's advertising copy: “What wheel can survive this beating?” and “...the new wheel too tough for the 'mean machine'” predated the crash at Indianapolis and was intended to emphasise the strength of the method of construction.

Twenty years on, the “parts bin special” idea was a part of local story-telling.  Although most doubt the tale, it's commonly recounted the 85 HSV VS GTS-R Commodores Holden built in 1996 were all finished in the same shade of yellow because of a cancelled order for that number of cars in "taxi spec", the Victorian government having mandated that color for the state's cabs.  While a pleasing industry myth, most suspect it's one of those coincidences and the government's announcement came after the bodies for the GTS-R had already been painted.  Being "taxi yellow" doesn't appear to have deterred demand and examples now sell for well into six figures (in Aus$).      

1971 Holden HQ Monaro LS 350

The overwrought and bling-laden Holden LE typified the tendency during the 1970s and of US manufacturers and their colonial off-shoots to take an elegant design and, with a heavy-handed re-style, distort it into something ugly.  A preview of the later “malaise era” (so named in the US for many reasons), it was rare for a facelift to improve the original.  The HQ Holden (1971-1974) was admired for an delicacy of line and fine detailing; what followed over three subsequent generations lacked that restraint although to be fair, while the last of the series (HZ, 1977-1980) ascetically wasn't as pleasing as the first, dynamically, it was much-improved.   

1973 Ford Falcon XA GT Hardtop (RPO83).

In the era of the LE, Ford Australia had it's own problem with unwanted two-door bodyshells.  Released too late to take advantage of what proved a market fad, Ford’s Falcon Hardtops (XA; 1972-1973, XB; 1973-1976 & XC; 1976-1979) never enjoyed the success of Holden’s Monaro (1968-1976), Chrysler’s Valiant Charger (1971-1978) or even that of Ford’s own, earlier Falcon Hardtop (XM; 1964-1965 & XP; 1965-1966).  The public’s increasing and unpredicted uninterest in the style meant that by 1976, like Holden, Ford had languishing in unwanted in their hands hundreds of body-shells for the big (in Australian terms although in the US they would have been classed “compacts”) coupés.  When released in 1972 Ford’s expectation was it would every year sell more than 10,000 Hardtops but that proved wildly optimistic and not even discounting and some “special editions” did much to stimulate demand.  By 1977 sales had dropped to a depressing 913 and with over 500 bodies in stock, the projection no more than 100 would attract buyers meant a surplus of 400; an embarrassing mistake.

Edsel Ford II with Falcon Cobra #001, publicity shot, Ford Australia's Head Office, Campbellfield, Victoria.  The badge below the Cobra decal reads 5.8; Australia switched to the metric system in 1973 but because of the nature of the machines, almost always the V8s are described either as 302 (4.9) or 351 (5.8), cubic inches being a muscle car motif. 

Scrapping them all had been discussed but in Australia at the time was Edsel Ford II (b 1948), great-grandson of Henry Ford (1863-1947), grandson of Edsel Ford (1893–1943) and the only son of Henry Ford II (1917–1987).  The scion had been sent to southern outpost to learn the family business and been appointed assistant managing director of Ford Australia; his solution profitably to shift the surplus hardtops was hardly original but, like many sequels, it worked.  What Edsel Ford suggested was to use the same approach which in 1976 had been such a success when applied in the US to the Mustang II (1973-1978): Create a dress-up package with the motifs of the original Shelby Mustangs (1965-1968), the most distinctive of which were the pair of broad, blue stripes running the vehicle’s full length.  In truth, the stripes had been merely an option on the early Shelby Mustangs but so emblematic of the breed did they become it’s now rare to see one un-striped.  The blinged-up Mustang IIs had been dubbed “Cobra II” and although mechanically unchanged, proved very popular.  One (unverified) story which is part of industry folklore claims the American’s suggestion was initially rejected by local management and discarded before a letter arrived from Ford’s Detroit head office telling the colonials that if Edsel Ford II wanted a Falcon Cobra with stripes, it must be done.  As Edsel's father once told a Lee Iacocca (1924–2019) who seemed to be getting ideas above his station: "Don't forget my name is on the building". 

Falcon Cobra #31.  The rear-facing bonnet (hood) scoop was the most obvious visual clue identifying the Option 97 (#002-031) cars although the after market responded and it became possible to buy replica scoops as well as the decals and plaques for those who wanted their own "Cobra look".

The Australian cars thus came to be “Cobra” and as well as providing a path to monetizing what had come to be seen as dead stock, the cars would also be a platform with which Ford could homologate some parts for use in racing.  The latter task was easy because in November 1977 Ford had built 13 “special order” XC Hardtops which conformed with the “evolution” rules of the Confederation of Australian Motor Sport (CAMS, then the regulatory body) for homologating parts for Group C touring car events.  Cognizant of the furore which had erupted in 1972 when high-output engines were homologated in road cars, the changes were mostly about durability and included enlarged rear wheel wells to accommodate wider wheels and tyres, a reverse hood (bonnet) scoop which drew desirable cool-air from the low-pressure area at the base of the windscreen, twin electric fans (switchable from the cockpit) which replaced the power-sapping engine-driven fan, a front tower brace (K-brace) which stiffened the body structure, an idler arm brace and front and rear spoilers.

Falcon Cobra #094 which was one of the "fully optioned" of the Option 96 build (#081-200 including the 351 V8, air-conditioning, power steering & power windows).

A prototype Falcon Cobra was built in April 1978 with production beginning the following July.  Unusually, all were originally painted Bold Blue before the areas which would become the stripes and the sill & wheel-arch highlights was masked with a coating of Sno White was painted over the top (thin Olympic (Blaze) Blue accent stripes separated the colors and “Cobra” decals were fitted to the sides and rear).  Each of the 400 built was fitted with a sequentially numbered plaque (001 to 400) on the dash and the production breakdown was:

#001: Created for promotional use, it was allocated for the photo-sessions from which came the images used in the first brochures (351 automatic).

#002-031: The Option 97 run which contained the parts and modifications intended for competition and produced in conformity with CAMS’s “evolution” rules (351 manual).

#032-041: 351 manual with air-conditioning (A/C) & power steering (P/S).

#042-080: 351 manual with A/C, P/S & power windows (P/W).

#081-200: 351 automatic with A/C, P/S & P/W.

#201-300: 302 manual.

#301-360 (except 351): 302 automatic with A/C & P/S.

#351: 351 manual.

#361-400: 302 automatic with A/C, P/S & P/W.

Moffat Ford Dealers team cars in the Hardie-Ferodo 1000 at Bathurst, finishing 1-2 in 1977 (left) and on the opening lap in 1978 (right).  In 1978, the cars (actually 1976 XB models modified to resemble XCs) matched their 1977 qualifying pace by starting second & third on the grid but in the race both recorded a DNF (did not finish). 

The Option 97 run (#002-031) included the modifications fitted to the 13 cars built in November 1997 but also included was engine & transmission oil coolers, a tramp rod (fitted only to the left-side because most racing in Australia is on anti-clockwise circuits and most turns thus to the left) and a special front spoiler which directed cooling air to the front brakes.  Visually, the Option 97 run was differentiated from the rest by the (functional) bonnet scoop and a pair of Scheel front bucket seats (part number KBA90018) in black corduroy cloth. Collectively, the 370 Option 96 and 30 Option 97 made up the 400 SVP (Special Value Pack) that was the Falcon Cobra.  The Cobra’s blue & white livery appeared on the race tracks in 1978 but the best known (the pair run by Allan Moffat's (v 1939) “Moffat Ford Dealers” team were actually modified XB Hardtops built in 1976 and the same vehicles which had completed the photogenic 1-2 at Bathurst in 1977.
