The Audi S4 is the high performance variant of Audi 's compact executive car A4 . The original Audi S4, built from 1991 until 1994, was a performance-oriented version of Audi's 100 saloon/sedan . All subsequent S4s since 1997 have been based on the Audi A4 ; and as the A4 has evolved from one generation to the next, so has the S4.
94-662: Like its regular A4 counterpart, all S4 variants have had longitudinally oriented , front-mounted engines. All versions of the S4 have their transmission mounted immediately at the rear of the engine in a longitudinal orientation, in the form of a transaxle , and like all Audi "S" cars , are only available as standard with Audi's quattro all-wheel drive (AWD) system, using a Torsen -based centre differential system. A more powerful internal combustion engine , larger upgraded brakes, firmer suspension , larger wheels, and distinctive sheetmetal, styling clues and badging have always been amongst
188-616: A B5 RS4 engine, and Alcon racing brake calipers (4 piston front and 2 piston rear calipers). Don Istook, with Istook's Motorsports, built and campaigned several B5 S4's in first the Motorola Cup, and then the Grand Am Cup. The S4's were even raced by Istook's Motorsports in the Rolex GT category for several races to help fill the field. Of note, one of the S4's, racing against true GT cars, even ran as high as second place (in
282-617: A V configuration . The first known V8 was the Antoinette , designed by Léon Levavasseur , and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Most engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance , which results in low vibrations. However,
376-496: A longitudinal engine is an internal combustion engine in which the crankshaft is oriented along the long axis of the vehicle , from front to back. See also: transverse engine This type of motor is usually used for rear-wheel drive cars, except for some Audi , SAAB , the Oldsmobile Toronado , and the 1967 Cadillac Eldorado equipped with longitudinal engines in front wheel drive. In front-wheel drive cars
470-426: A longitudinal engine layout and rear-wheel drive (or all-wheel drive). However, V8 engines have also occasionally been used in transverse engine front-wheel drive vehicles, sometimes using closer cylinder bore spacings and narrower cylinder bank angles to reduce their space requirements. The classification of 'big-block' or 'small-block' refers to the engine's external dimensions and does not necessarily indicate
564-402: A transverse engine is usually used. Trucks often have longitudinal engines with rear-wheel drive. For motorcycles, the use of a particular type depends on the drive: in the case of a chain or belt drive a transverse engine is usually used, and with shaft drives a longitudinal engine. Longitudinal engines in motorcycles do have one disadvantage: the "tipping point" of the crankshaft tilts along
658-408: A 'default' asymmetric 40:60 front-rear torque split on manual transmission models, along with the later Bosch ESP 8.0 Electronic Stability Programme and gloss black painted brake calipers . The 'Avus-III' wheels now became an option, and were replaced by a standard offering 8.0Jx18 inch 'S-design' 7-spoke forged alloy wheel. Bose sound system is now standard, whereas it was optional on
752-544: A 2.5 L (153 cu in) V8 engine. BMW's first V8 engine was the 1954–1965 BMW OHV V8 engine , a petrol engine with overhead valves and all-aluminum construction. The company resumed production of V8 engines in 1992 with the BMW M60 aluminum double overhead camshaft engine, and V8 engines have remained in production until today. BMW's first turbocharged V8 engine was the 1998–2009 M67 twin-turbocharged diesel engine. The first turbocharged V8 petrol engine from BMW
846-569: A 240 mm (9.4 in) single plate dry clutch , and Torsen T-2 quattro permanent four-wheel drive system. Final drive (parts code prefix: 01R, identification code: EXZ) ratios are 3.889, giving a top gear road speed to engine revs ratio of 24.4 miles per hour (39.3 km/h) per 1000 rpm. From July 2003, the ZF 6HP19 tiptronic automatic transmission (parts code prefix: 09L, identification codes: GUR, HHU) (ratios - 1st: 4.171, 2nd: 2.340, 3rd: 1.521, 4th: 1.143, 5th: 0.867, 6th: 0.691, with
940-525: A 5.6 L (340 cu in) Chrysler LA engine and built on the chassis of a 1950s Chrysler Imperial. The 1934–1938 Tatra 77 rear-engined sedan was initially powered by 3.0 L (183 cu in) petrol V8, which was air-cooled and used an overhead camshaft that operated the valves using a 'walking beam' rocker arrangement. This model line continued until 1999 when the Tatra 700 ended production. Tatra also produced diesel V8 truck engines from
1034-626: A 7.5Jx16H2 ET35 six spoke "Avus", and an 8.0Jx17H2 ET40 ten-spoke. The second generation S4 ( Type 8D ), also known as the Audi S4 quattro debuted in 1997, with factory production commencing October 1997, as part of the facelifted B5 platform Audi A4 line-up, although it was not available in North America until late 1999. In addition to the saloon (sedan), an estate version (wagon)–the Audi S4 Avant–was introduced into

#17327800395681128-489: A FF transverse engine bay. By contrast most mainstream modern vehicles use front wheel drive along with a transverse engine arrangement since they are usually equipped with inline-4 or V6 engines. While both layouts can be adapted for all-wheel drive , the longitudinal engine orientation has a more balanced weight distribution leading to superior handling characteristics, but is less efficient in terms of packaging and interior space. Cars with longitudinal engines usually have
1222-445: A V-angle of 45 degrees. Most V8 engines fitted to road cars use a cross-plane crankshaft since this configuration produces less vibration due to the perfect primary balance and secondary balance. The cross-plane crankshaft has the four crank pins (numbered from the front) at angles of 0, 90, 270, and 180 degrees, which results in a cross shape for the crankshaft when it is viewed from one end. The rumbling exhaust sound produced by
1316-570: A V-angle of 90 degrees and was built in displacements of 4.1 L (253 cu in) and 5.0 L (308 cu in), the latter being de-stroked to 5.0 L (304 cu in) in 1985. The Holden V8 engine was used in various models, including the Kingswood, Monaro, Torana, Commodore, and Statesman. Versions tuned for higher performance were sold by Holden Dealer Team and Holden Special Vehicles , including versions stroked to up to 5.7 L (350 cu in). The Holden V8 engine
1410-591: A V8 engine was the 1965 Chrysler Valiant (AP6) , which was available with an American-built 4.5 L (273 cu in) Chrysler engine. The first locally designed V8 Ford was the 1966 Ford Falcon (XR) and the first V8 Holden was the 1968 Holden HK , both using engines supplied by their parent companies in the United States. The first V8 engine to be mass-produced in Australia was the 1969–2000 Holden V8 engine . This cast-iron overhead valve engine used
1504-464: A V8 engine was the 1988 Audi V8 luxury sedan. Its first model to use a V8 diesel engine was the D2 A8 3.3 TDI in 2000. The first V8-engined Alfa Romeo road car was the 1967–1969 Alfa Romeo 33 Stradale mid-engined sports car, of which 18 were produced. This was followed by the 1970–1977 Alfa Romeo Montreal front-engined sports car. The engines for both cars are based on the 90-degree V8 engine from
1598-504: A common 4.2-litre V8 engine , the first time that a V8 engine was placed in a compact executive car, placing it in direct competition with the BMW M3 (3.2 L inline 6 ) and Mercedes-Benz C32 AMG (3.2-litre supercharged V6). The B8 generation uses a supercharged 3.0-litre V6 TFSI engine and competed with the BMW 335i , BMW 335i/340i xDrive , and Mercedes-Benz C350 . The current B9 generation
1692-503: A conventionally mounted Lucas - Girling caliper in an external position over the disc. US models had smaller 276 mm (10.87 in) discs. The rear brakes, 269 mm (10.59 in) by 20 mm (0.787 in) and also radially ventilated - remained the same throughout C4 production; they used a Lucas-Girling single-piston sliding caliper with an integrated cable-actuated handbrake mechanism. A Bosch three-channel operation (four-channel sensing) Anti-lock Braking System (ABS) with
1786-649: A dual-rate tandem vacuum servo provided the brake actuation. Standard wheels were 'Avus-III' die-cast aluminium alloy, 8.0Jx18H2 ET45 in size, and fitted with 235/40 ZR18 95Y XL (eXtra Load) high performance tyres, with factory supplies being either Continental SportContact2 or Michelin PilotSport PS2. Discrete lower door trims, along with the now trademark Audi 'S' model vertical-emphasis line grille, and solid aluminium (later replaced with plastic covered by aluminium) exterior door mirrors , and S4 badging front and rear are all that visually distinguish
1880-1198: A final drive (identification code: GDF) ratio of 3.539) was included as an option. An unusual sight in the engine compartment was the addition of water cooling for the 190 amp alternator , along with two additional thermostatically -controlled side-mounted radiators . The B6 S4 came equipped with electronically controlled, variable assisted ' servotronic ' rack and pinion power assisted steering (PAS) as standard. B6 S4 brakes consisted of radially ventilated disc brakes front and rear. The front discs are sized at 345 mm (13.58 in) in diameter by 30 mm (1.181 in) thick, and are clamped by Continental Teves-ATE FNRG-60 single-piston sliding brake calipers . The rears are 300 mm (11.81 in) by 22 mm (0.866 in), and again use single-piston sliding calipers, with an integrated cable-operated hand brake mechanism. A Bosch ESP 5.7 Electronic Stability Programme system, complete with Anti-lock Braking System (ABS), Electronic Brakeforce Distribution (EBD), Emergency Brake Assist (EBA), Electronic Differential Lock (EDL) and Anti-Slip Regulation (ASR) - also known as traction control system , coupled with
1974-495: A five-speed manual was the only transmission available in North America; a four-speed automatic transmission (parts code prefix: 01F, identification code: CBF) was available as an option worldwide. Front and rear axle final drive ratio is either 4.111 or 3.889 (dependent on transmission type), and the rear axle (parts code prefix: 017, identification codes: AAT, AET) uses a driver-selectable electro-pneumatic-mechanical switchable diff lock .

SECTION 20
#17327800395682068-427: A flat billet and does not require counterweights so it is lighter. However, it produces more vibration due to a secondary imbalance. Most early V8 road car engines also used a flat-plane crankshaft since this was simpler to design and build than a cross-plane crankshaft. Early flat-plane V8 engines included the 1910 De Dion-Bouton engine, the 1915 Peerless engine, and the 1915 Cadillac engine. A flat-plane crankshaft
2162-507: A front-wheel-drive layout (with an on-demand all-wheel drive system in the case of the Volvos ). To reduce the vibrations caused by the unbalanced 60-degree V-angle, the Volvo engines used a balance shaft and offset split crankpins . The Rolls-Royce Meteorite tank engine also used a 60-degree V-angle, since it was derived from the 60 degree V12 Rolls-Royce Meteor which in turn was based on
2256-509: A limited edition run of 250 special edition S4 saloon cars, celebrating 25 years of quattro four wheel drive. This exclusive model was called the Audi S4 25quattro . Available only in the United States, the exterior has unique front and rear bumpers, a carbon fibre boot lip spoiler and lower front splitter, a rear functional red tow hook, and a high gloss Phantom Black painted grille with the "quattro" emblem. 15-spoke DTM alloy wheels, along with optional dealer-fitted 'Audi four-rings' decals for
2350-402: A mechanical load sensing valve for the rear brakes was standard throughout production. For wheel options, the standard five-arm "Fuchs" forged alloy wheels were 8.0Jx16H2 ET40, and were fitted with 225/50 R16 sized tyres. Several other tyre and wheel designs were optionally available: a 7.5Jx15H2 ET40 six-spoke with 215/60 R15 tyres, an 8.0Jx16H2 ET40 five-double-spoke,
2444-462: A mix of imported and local parts. A 4.4 L (269 cu in) version of the Rover V8 engine was produced in Australia for the ill-fated 1973–1975 Leyland P76 sedan. The engine had an overhead valve design and was the only all-aluminum engine made in Australia. The 1958–1965 Hongqi CA72 was a luxury car, of which approximately 200 were built for government officials. It was powered by
2538-575: A motive power output of 169 kW (230 PS; 227 bhp) at 5,900 revolutions per minute (rpm) and 350 newton-metres (258 lbf⋅ft) of torque 1,950 rpm. This powerplant made it rather powerful by contemporary standards, and the vehicle with five-speed manual transmission was able to accelerate from standstill to 100 kilometres per hour (62.1 mph) in 6.2 seconds. Both five- and six-speed manual transmissions (parts code prefix: 01E, identification codes: five-speed: CBD, CET, six-speed: CBL, CMG) were offered to European customers, but
2632-478: A single overhead camshaft and was rear-mounted in the vehicles. The company's first V8 road car was the 1973–1974 Dino 308 GT4 mid-engined sports car. The engine is a 90-degree all-aluminum V8 with double overhead camshafts. In 1975, the 2.0 L (122 cu in) engine in the Ferrari 208 GT4 became the smallest production V8 engine ever produced. The model lineage of mid-engined V8 road cars continues to
2726-453: A smaller minimum turning circle than those with transverse engines. This is because there is more space to the sides of the engine, allowing deeper wheel arches so the front wheels are able to turn through a greater angle. In the late 1960s, GM divisions Oldsmobile and Cadillac had front-wheel drive models Toronado and Eldorado respectively, with a longitudinal V8 engine and an integrated automatic transmission and differential unit powering
2820-430: A standstill to 60 mph (96.6 km/h) in less than 5 seconds, and make it to 200 km/h (124.3 mph) in slightly over 20 seconds, although doing this led to fuel consumption dipping into single digits. This was considerably worse than the earlier V6 models, leading to the addition of a $ 1,700 gas guzzler tax (combined 20.2 miles per US gallon (11.6 L/100 km; 24.3 mpg ‑imp )) for
2914-602: A strengthened alloy crankshaft bedplate for the five main bearings , and a two-part baffled oil sump, and a light-alloy variable intake manifold (VIM), containing the fractionally sequentially actuated fuel injectors . This petrol engine, based on the unit from the Audi A8 , displaces 4,163 cubic centimetres (254.0 cu in), and it produces a motive power output of 344 PS (253 kW; 339 bhp) at 7,000 rpm, and generates torque of 410 N⋅m (302 lbf⋅ft) at 3,500 rpm, making it more powerful than

3008-654: A strict ruleset to follow until the 1972 season, when engines were no longer allowed to be any bigger than 358 cu in (5.9 L) for the purpose of reducing speeds caused by the rapid aerodynamic advancements from 1969 to 1971. In the American Top Fuel class of drag racing, V8 engines displacing 500 cu in (8 L) today produce outputs of over 7,000 kW (10,000 hp). and 10,000 N⋅m (7,400 lb⋅ft). The engines used in Top Fuel and Funny car drag racing are typically based on
3102-485: A two-door four-seat Cabriolet ( convertible ), Type 8H , was included in the model range . Official performance figures for standard discipline of sprinting from standstill to 100 km/h (62.1 mph) in the saloon with manual transmission are 5.6 seconds (Avant 5.8 s, Cabriolet 5.9 s), however, a road test conducted by the American automotive magazine Motor Trend indicated that it could go from
3196-491: A typical cross-plane V8 engine is partly due to the uneven firing order within each of the two banks of four cylinders. A usual firing order of L-R-L-L-R-L-R-R (or R-L-R-R-L-R-L-L) results in uneven intake and exhaust pulse spacing for each bank. When separate exhaust systems are used for each bank of cylinders, this uneven pulsing results in the rumbling sound typically associated with V8 engines. However, racing engines seek to avoid these uneven exhaust pressure pulses to maximize
3290-663: Is commonly referred to as the Ur-S4 , derived from the German : Ur sprünglich augmentive word (meaning: original). Audi mildly updated the C4-based model line in 1994 and dropped the 100 nomenclature; all variants of the former Audi 100 line were now re-badged as the Audi A6 . In line with the switch in model name, Audi temporarily discontinued the use of the S4 name and began selling an updated but fundamentally identical version of
3384-409: Is considered to be the first V8 engine produced in significant quantities. The 1914 Cadillac L-head V8 engine is considered the first road-going V8 engine to be mass-produced in significant quantities, with 13,000 sold the first year. This engine was built in the United States and was greatly assisted by Cadillac's pioneering use of electric starter motors . The popularity of V8 engines in cars
3478-562: Is now taken by the Audi S5 Cabriolet and new Coupe. Unlike previous generations of the S4, only the sedan was imported to the United States and Canada. Compared to the previous B6/B7 S4 which used a 4.2-litre V8 engine , the B8 S4 uses a smaller displacement 3.0-litre TFSI V6 engine , but now with the addition of forced induction via an Eaton mechanical supercharger . Longitudinal engine In automotive engineering ,
3572-524: Is powered by a turbocharged 3.0-litre V6 TFSI engine, with rivals including the BMW M340i xDrive and Mercedes-Benz C450 AMG/Mercedes-AMG C43 4MATIC . All versions of the S4 have been manufactured at Audi's plant in Ingolstadt , Germany; they are, or have been available as a four-door five-seat saloon and a five-door five-seat Avant (Audi's name for an estate car/station wagon ) body styles since
3666-608: Is still classified by the internal designation: Typ 8E (although with revised sub-designations - saloon: 8EC, Avant: 8ED, and Cabriolet: 8HE). It has the same 4.2-litre V8 engine (identification code: BBK ) as the B6 S4, producing a power output of 253 kW (344 PS; 339 bhp) at 7,000 rpm, and 410 N⋅m (302 lbf⋅ft) torque at 3,500 rpm. There are a few mechanical changes, such as revised springs and dampers and, from model year 2007, an updated Torsen T-3 automatically biasing centre differential, featuring
3760-534: Is used by many V8 engines fitted to racing cars. From the gas dynamics aspect, the flat-plane crankshaft allows for even exhaust gas pulses to be achieved with a simple exhaust system. The design was popularized in motor racing by the 1961–1965 Coventry Climax FWMV Formula One engine, and the 1967–1985 Cosworth DFV engine was highly successful in Formula One. Several production sports cars have used flat-plane V8 engines, such as every Ferrari V8 model (from
3854-440: The 1962 , 1963 , 1964 , and 1965 seasons were won by drivers of V8-powered cars. From 1962 through 1965, the top three manufacturers in each season's Constructor's Championship all predominantly used V8 engines in their cars. In 1966, the engine capacity limits were increased to 3.0 L (183 cu in) (or 1.5 litres with a supercharger), and both the 1966 and 1967 Constructor's Championships were won by cars powered by

The 33 Stradale engine has a displacement of 2.00 L (122 cu in) and a flat-plane crankshaft, while the Montreal uses an engine enlarged to 2.6 L (160 cu in) and uses a cross-plane crankshaft. The 2007–2010 Alfa Romeo 8C Competizione / Spider sports cars are powered by a 4.7 L (290 cu in) version of
4042-632: The Australian Ford Falcon and Ford Fairlane models. It was also used in several low-volume DeTomaso sports cars and luxury sedans built in Italy. Australian production ceased in 1982 when Ford Australia temporarily stopped production of V8 cars. From 1991 until 2016, the Ford Falcon was available with the imported Ford Windsor , Ford Barra , or Ford Modular V8 engines; the latter was marketed as "Boss" and locally assembled from

Under normal grip conditions, this is set with a default rearwards torque distribution bias of 40:60 front to rear, and a maximum of 100% torque can automatically be apportioned to the rear axle (and up to 80% to the front) as conditions warrant. The final drive ratios are 3.889. From November 2008,
4230-712: The Brabham-Repco V8 engine . From 1968 until 1981, the Cosworth DFV V8 engine dominated Formula One racing. During this time, the Manufacturers' Championship was won by Cosworth DFV-powered cars every season except 1975, 1976, 1977, and 1979, which 12-cylinder Ferraris won. After a long period of dominance, the Cosworth DFV was eventually outpaced by turbocharged straight-four and V6 engines. The next period of significant V8 usage in Formula One
4324-569: The Ferrari F136 engine with a cross-plane crankshaft. Ferrari's first contact with V8 engines was the Vittorio Jano -designed 1955 Lancia-Ferrari D50 , a Formula One racing car that the company acquired as part of its purchase of Lancia's Formula One racing department. The first Ferrari-developed V8 engines were used in the 1962 Ferrari 248 SP and Ferrari 268 SP sports prototype racing cars designed by Carlo Chiti . This engine had
4418-661: The Hewitt Touring Car became the first car built in the United States with a V8 engine. The engine was designed and built by Edward R. Hewitt who emphasized the V8's superiority to the typical I4 and I6 and six-cylinder engines of the time because of its lower weight and easier to make crankshaft compared to the I6s of equal power as well as the V8 not taking much more space than a I4. The 1910 De Dion-Bouton — built in France—
4512-513: The RS2 Avant , and nearly as powerful as the B5 RS4 . Engine management was by way of a Bosch Motronic ME 7.1.1 electronic engine control unit (ECU), using a Bosch 'E-Gas' drive by wire electronic throttle, and powering eight individual spark coils with longlife quad-electrode Bosch spark plugs. Ignition timing is a mapped direct ignition, with cylinder-selective knock control with

The Lancia Trikappa , Lancia Dilambda , and Lancia Astura , produced 1922–1939, used narrow angle V8 engines (based on the Lancia V4 engine ) with V-angles of 14–24 degrees. The 1932 Miller four-wheel drive racing cars used a V8 engine with a V-angle of 45 degrees. The 8-cylinder versions of the 1945 through 1966 EMD 567 diesel locomotive engine also used
4700-653: The 1939 Tatra 81 to the present day Tatra 815 . French manufacturers were pioneering in their use of V8 engines in the early 1900s with the 1904 Antoinette aircraft engine (the first known V8 engine) and the 1910 De Dion-Bouton . However, there were few French automotive V8 engines in the following decades, with manufacturers such as Delage , Delahaye , Talbot-Lago , Bugatti , and Hotchkiss using six-cylinder or straight-eight engines instead. From 1935 until 1954, Matford (Ford's French subsidiary, later renamed to ' Ford SAF ') produced cars with V8 engines, closely based on contemporary American Ford models. Simca purchased

V8 engines intended for motorsport are often small and short-stroke to maximize RPMs and thus power. The Cosworth DFV 3.0 L (183 cu in) is such an engine. Due to its large external dimensions, V8 engines are typically used in cars that use
5076-477: The B6 S4, and an enhanced optional DVD-ROM -based RNS-E satellite navigation system replaces the previous CD-ROM -based RNS-D option. The new trapezoidal single-frame grille, Bi- Xenon high-intensity discharge lamp (HID) headlamps, L-shaped tail-lamps, quad exhaust tail pipes, and discrete V8 badging below the side repeater indicators help distinguish the B7 from the previous B6 model.

Available options included: The Sport Package replaced the wood-grain belt line trim with silver aluminum trim, and the wood grain finish around the shifter with black plastic. The Alcantara seat inserts were silver (on Onyx leather). With the black, white, or blue exteriors, the inserts were also available in blue Alcantara. On
5640-402: The actual engine displacement. Engines with displacements from 6.0 to 6.6 L (366 to 403 cu in) have been classified as both small-block and big-block, depending on the particular manufacturer's range of engines. V8 engines have been used in many forms of motorsport, from Formula One , IndyCar , NASCAR , DTM and V8 Supercars circuit racing, to Top Fuel drag racing. Among
5734-417: The aid of four knock sensors. The exhaust system includes vacuum-operated valves in the twin rear silencers (mufflers), finished with chrome plated tail-pipes. Like its predecessors, the B6 S4 was standard with a Getrag six-speed (M6S) manual transmission (parts code prefix: 0A3, identification codes: FVD, HEP) ( gear ratios - 1st: 3.667, 2nd: 2.050, 3rd: 1.462, 4th: 1.133, 5th: 0.919, 6th: 0.778), with

The world's fastest non-jet-powered (i.e., piston-engine powered) wheeled land vehicle, the Speed Demon, which achieved a speed of 744.072 km/h (462.345 mph) in 2017, is powered by a V8 engine based on the Chevrolet small-block engine design. The first Australian-designed car to use
5922-548: The car, based on the "new" A6 and badged as S6 . Despite the change in name, differences between the outgoing S4 and incoming S6 were cosmetic and very light. A more powerful, more expensive and more exclusive variant known first as the S4 Plus and later as the S6 Plus was available from October 1992 through to July 1994. Built in very small numbers, the "Plus" models featured numerous performance enhancing upgrades; including
6016-464: The differential housing. Shock absorbers , coil springs , and anti-roll bars are fitted front and rear. The B5 S4 brake system consisted of radially ventilated discs, 321 mm (12.64 in) in diameter by 30 mm (1.18 in) thick up front, and 256 mm (10.08 in) by 22 mm (0.87 in) at the rear. Two-piston Lucas HP2 brake calipers at the front (with four pads per caliper), with Lucas single-piston sliding brake calipers at
6110-495: The downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO , the 2005–2011 Volvo XC90 , and the 2006–2009 Volvo S80 . The Ford engine used a 60-degree V-angle because it was based on a V6 engine with a 60-degree V-angle. Both the Ford and Volvo engines were used in transverse engine chassis, which were designed for
6204-581: The early 2000 models, the Alcantara inserts in the rear seats did not fully extend forward to the front edge of the seat. A motor racing version of the car achieved great success in the SpeedVision World Challenge with Michael Galati taking the 2001 SpeedVision GT title in a Champion Racing S4, winning four races, and helping Audi to its first Manufacturers' Championship. The Audi Sport specification Champion A4 chassis included
6298-424: The entire motorcycle to a greater or lesser degree when accelerating. This is partly resolved by having other components, such as the generator and the gearbox, rotate in the opposite direction to the crankshaft. Most larger, "premium" vehicles use the longitudinal engine orientation in combination with rear wheel drive , because powerful engines such as the inline-6 and 90° big-bore V8 are usually too long to fit in
6392-460: The first German V8 engines was the 1928–1945 Argus As 10 aircraft engine. This engine was air-cooled, used an 'inverted V' design, and was used in several training, surveillance, and communications airplanes. From 1933 until 1940, the Horch 830 luxury cars were powered by V8 engines (sold alongside Horch's larger straight-eight engines). Shortly after, the 1934–1937 Stoewer Greif V8 was powered by
6486-399: The first V8 Formula One cars to compete were the 1952 AFM entry and the 1954 Lancia D50 , with a development of the latter powering Juan Manuel Fangio's 1956 car to victory in the driver's championship. The 1.5 L Formula One era of 1961–1965 included V8 engines from Ferrari, Coventry Climax, British Racing Motors (BRM), and Automobili Turismo e Sport (ATS). The driver's championships for
6580-542: The fourth generation of the 'Audi S4 quattro' ( Typ 8K ) entered factory production. It is based on the Audi B8 A4 , built on the Volkswagen Group MLB/MLP platform . Unlike the previous B6 and B7 models, the new B8 version was only available as a four-door five-seat saloon (sedan), or a five-door five-seat Avant (estate/wagon). The sport-performance two-door four-seat Cabriolet ( convertible ) mantle
6674-470: The front doors complete the exterior makeover. Black and grey contrasting interior leathers, along with "quattro" embossed into the Recaro seats, together with a "1 of 250" exclusive quattro gear shift knob for the manual-only gearbox define the interior changes and act as a subtle reminder of the exclusivity that the limited numbers command. On the mechanical side, the S4 25quattro was the second Audi, after

6956-505: The lineup from 1998. Production of the B5 S4 ceased in September 2001, although it was still sold together with the next B6 platform generation through 2002 in North America. Examples produced June 2001 to end of production are 2002 Model Year cars, the 10th digit of the VIN being the number "2". Several years after it was sold new, the B5 S4 remains a potent enthusiast car, and as featured in
7050-498: The many upgrades the S4 receives over its mainstream 100 and A4 siblings. In markets where the even higher-performance Audi RS 4 is not offered, the S4 is the top-of-the-line trim of the A4 family. A single turbocharged 2.2-litre inline five-cylinder powered the original C4 version, and a 2.7-litre twin turbocharged V6 engine was found in the B5 generation. The B6 and B7 versions shared
7144-605: The model's inception in 1991. A two-door four-seat Cabriolet ( convertible ) S4 variant was introduced as part of the B6 and B7 generation A4 lineups. The B8 Cabriolet has now been built off the A5 coupe body style and the "S" variant is marketed under the Audi S5 nameplate. Factory production of the original Audi S4 ( Typ 4A ), usually known as Audi 100 S4 , began in August 1991 to serve as
7238-451: The performance version of the newly updated, C4 platform, 100-series four-door, five-seat saloon. First shown to the public at the May 1991 Barcelona Show , it was designed to replace the outgoing C3 -based Audi 200 turbo quattro 20V and retained its five-cylinder engine. The 200, Audi's first true sports-saloon, had been discontinued at the end of 1990. Being the first S4 model from Audi, it
7332-585: The power output. The 1960s cross-plane V8 racing engines used long primary exhaust pipes (such as the Ford GT40 endurance racing car) or located the exhaust ports on the inside of the V-angle (such as the Lotus 38 IndyCar) to link the exhaust systems from each bank and provide even exhaust gas pulses),. A flat-plane crankshaft configuration provides two benefits. Mechanically, the crankshaft can be machined from
7426-458: The quickest saloon/sedan in the Audi model line, and among the quickest saloon/sedans in the world at that time. The B5 S4 is fitted with 4-wheel independent suspension . The front suspension is a multi-link design with four individual control arms per wheel. The rear suspension is an unequal length double wishbone design; the lower control arms are mounted to a subframe which also carries

The B6 S4 saloon and Avant variants ceased factory production in December 2004, with the Cabriolet ending twelve months later at December 2005. Replacing the 2.7-litre ' biturbo ' V6 engine of the previous generation B5 S4, the new B6 S4 powertrain gained an all-aluminium alloy 4.2-litre, 40 valve (five valves per cylinder) V8 engine (parts code prefix: 079.C, identification code: BBK ), with flywheel-end chain-driven double overhead camshafts , roller-finger rocker arm cam followers , and included variable inlet camshaft timing . It also used
7896-472: The then current Audi B6 A4 . Despite having moved to an entirely new platform, one of the S4's most publicised new features was its new engine - a 4.2-litre V8 engine . Following its initial launch of either a four-door five-seat saloon (sedan), or a five-door five-seat Avant (estate/wagon), it eventually became available in three bodystyles - and for the first time in the Audi 'S' car range , from February 2004,
7990-475: The use of Audi's 4.2-litre V8 engine in place of the then current inline-five engine . An all-new C5 -based Audi A6 debuted for 1997, after which the S4 and S6 became distinctly separate models based on very different platforms . The C4 variant S4 ended factory production after less than three years in July 1994. One of its most renowned owners was Ayrton Senna who owned a silver Avant, not least because he
8084-627: Was also used in touring car racing and formed the basis of the Repco-Holden engine used in Formula 5000 racing. In 1999, the Holden V8 engine began to be replaced by the imported General Motors LS1 V8 engine. In 1971, Ford Australia began local production of the Ford 'Cleveland' V8 , an overhead valve cast-iron engine. The engine was produced in displacements of 4.9 L (302 cu in) and 5.8 L (351 cu in) for use in
8178-700: Was by way of a Bosch Motronic ME 7.1 (7.0 in North America) electronic engine control unit (ECU), and helped it meet the European EU-3D emissions standard.

Porsche's first road car to use a V8 engine was the 1978 Porsche 928 coupe. Its first to use a V8 diesel engine was the second-generation Cayenne S Diesel in 2014. Audi's first road car to use
8366-496: Was from 2006 to 2013 , when the rules mandated use of 2.4 L (146 cu in) naturally-aspirated V8 engines, with regular power outputs between 730 and 810 hp (in order to reduce the power outputs being achieved by the previous 3.0 litre V10 engines). These were replaced by 1.6 litre turbocharged V6 engines for the 2014 and later seasons. V8 engines have dominated American premier stock car racing NASCAR series since its inaugural 1949 season . However, there wasn't
8460-466: Was significantly increased following the 1932 introduction of the Ford Flathead V8 . By the early 21st century, the use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more fuel efficient , lower capacity engines, or hybrid and electric drivetrains . The displacement of modern V8 engines is typically from 3.5 to 6.4 L (214 to 391 cu in). However, larger and smaller examples have been produced, such as
