    The Audi Quattro is a road and rally car, produced by the German automobile manufacturer Audi, now part ofthe Volkswagen Group. It was first shown at the 1980 Geneva Motor Show on 3 March.

    The word quattro is derived from the Italian word for "four". The name has also been used by Audi to refer tothe quattro four-wheel-drive system, or any four-wheel-drive version of an Audi model. To avoid confusion, theoriginal Quattro model is also commonly referred to as the Ur-Quattro - the "Ur- " (German for "primordial","original", or "first of its kind") is an augmentative prefix, in this case meaning "original", and is also applied tothe first generation Audi S4 and Audi S6 models, as in "Ur-S4" and "Ur-S6" and was known for its legendarysound.

    The Audi Quattro was the first rally car to take advantage of the then-recently changed rules which allowed theuse of four-wheel drive in competition racing. It won competition after competition for the next two years .[1] Tocommemorate the success of the original vehicle, all subsequent Audis with their trademark quattro four-wheel-drive system were badged "quattro" with a lower case "q" and in a distinct typeface which has remained nearlyunchanged since its inception. The original car with the upper case "Q" in the Quattro name is a collector's

    piece.

    The Audi Quattro shared many parts and core body components with the Audi Coup, which was a member ofthe Audi 80 (B2) model range .[1] The Quattro was internally designated Typ 85 , a production code it shared withthe quattro versions of the Audi Coup (B2) and Audi 80. Its characteristic flared wheelarches were styled byMartin Smith. The Audi Quattro also had independent rear suspension and independent front suspension.

    Production history

    The idea for a high-performance four-wheel-drive car was proposed by Audi's chassis engineer, Jrg Bensinger,in 1977, when he found that the Volkswagen Iltis could outperform any other vehicle in snow, no matter how

    powerful. Bensinger's idea was to start developing an Audi 80 variant in co-operation with Walter Treser,Director of Pre-Development.

    European market

    Audi released the original Quattro to European customers in late 1980, making it both the first car to featureAudi's quattro permanent four-wheel drive system (hence its name), and the first to mate four-wheel drive witha turbocharged engine.

    The original engine was the 2,144 cc (131 cu in ) (2.1 L), inline-5-cylinder 10 valve SOHC , with a turbocharger and intercooler . It produced 147 kW (200 PS; 197 bhp ) and torque of 285 Nm (210 lbfft ) at 3500 rpm;

    propelling the Quattro from 0 to 100 km/h (62 mph) in 7.1s, and reaching a top speed of over 220 km/h(137 mph).

    3/5

    The engine was eventually modified to a 2,226 cc (136 cu in) (2.2 L) inline-5 10 valve, still producing147 kW(200 PS; 197 bhp), but with peak torque lower in the rev-range .[1] In 1989, it was then changed to a 2,226 cc(136 cu in) inline-5 20v (2.2 L 20v) DOHC setup producing 162 kW (220 PS; 217 bhp), now with a top speedof 230 km/h (143 mph)

    Audi Quattros are often referred to among owners and enthusiasts by their engine codes, to differentiate between the earlier and later versions: the earliest 2144 cc 10v being the "WR" engine, the 2226 cc 10v beingthe "MB" engine, and the later 20v being the "RR" engine. Hence, Quattro models may be referred to as eitherthe WR Quattro , MB Quattro , and RR or "20v" Quattro , respectively.

    Quattro car production was 11,452 vehicles over the period 1980 1991, and through this 11 year productionspan, despite some touch-ups, there were no major changes in the visual design of the vehicle. For the 1983model year , the dash was switched from an analogue instrument cluster, to a green digital liquid crystal display(LCD) electronic instrument cluster . This was later changed in 1988 to an orange LCD electronic instrumentcluster. The interior was redesigned in 1984, and featured a whole new dash layout, new steering wheel design,and new centre console design, the switches around the instrument panel were also redesigned at this time. In1985 the dash changed slightly with harder foam and lost a diagonal stripe, the dash switches were variedslightly and the diff lock pull knob gave way to a two-position turning knob with volt and oil temp digitalreadouts.

    External styling received very little modification during its production run. Originally, the car had a flat frontedgrille featuring four separate headlamp lenses, one for each of the low and high beam units. This was altered forthe 1983 model year, and replaced with combined units featuring a single lens, but housing twin reflectors. Thiswas changed again, for the 1985 model year, in what has become known as the 'facelift model' and includedsuch alterations as a new sloping front grille, headlights, and trim and badging changes. Max speed was124 mph . The RR 20v Quattro also featured a new three spoke steering wheel design, leather covering for doorarm rests, gloveboxes, centre console and door pockets. There was also a full length leather-wrapped centreconsole running all the way to the rear seats. 20v was also the first Ur-Q to have "quattro" script interior with

    partial leather seats. The floor on the drivers side had a bulge due to dual catalytic exhaust setup. The differentmodels may be distinguished by the emblems on their boot lids: the WR had a vinyl 'quattro' decal or a brushed

    aluminium effect plastic emblem, the MB had chrome plated 'audi', 'audi rings' and 'quattro' emblems, whilst theRR had only chrome plated 'audi rings'.

    The rear suspension was altered early on with geometry changes and removal of the rear anti-roll bar to reducea tendency for lift-off oversteer. For the 1984 facelift, the wheel size went from 6x15-inch with 205/60-15 tyresto 8x15-inch wheels with 215/50-15 tyres. At the same time the suspension was lowered 20 mm with slightlystiffer springs for improved handling. For 1987, the Torsen centre differential was used for the first time,replacing the manual centre differential lock.

    North American market

    Sales of the Quattro in North America began with the 1983 model year , which were constructed concurrently,and were of the same design as, the European 1982 models (they did not include the minor cosmetic changes ofthe European 1983 model) and continued through 1986. Total sales in the USA were 664. Canadian marketreceived cars that were identical to the US cars with exception of the speedometer , which was metric like theearly Euro cars. Official sales figures for Canada were 99, which included 61 in 1983, 17 in 1984, 18 in 1985and 3 in 1986. Although it's believed that there might have been up to 6 cars bought in 1986.

    US/Canadian cars were also equipped with larger impact bumpers with built-in shock absorbers, just like therest of the 4000/Coup models. None of the cars came with Anti-lock Braking System (ABS), however theywere otherwise "loaded" with options, including air conditioning , and in 90% of the cars, leather upholstery.Most of the 1984 and 1985 Canadian models did not have sunroofs .

    The remainder of the electric, suspension and cosmetic updates took place at the same time as the Europeancars. Out of 99 cars imported to Canada 35 are still known to be on the road.

    The initial 2.1L (2144cc, engine code "WX") engine for US/Canadian models included minor component andengine control unit (ECU) changes, including lowered turbocharger boost pressure, different camshaft , emissioncontrols including catalytic converter , and lambda stoichiometric fuel control, which lowered power to 160 hp(119 kW; 162 PS). Otherwise, mechanical specifications were identical to the European spec cars. The WXengine was also used on Swiss and Japanese market cars. In fact Audi built 200 special edition cars in 1988with WX engine and analogue instruments, the rest of the car was identical to the MB cars of that year.
