The Audi S4 is the high performance variant of Audi'south compact executive machine A4. The original Audi S4, congenital from 1991 until 1994, was a operation-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.
A more powerful internal combustion engine, larger upgraded brakes, firmer interruption, larger wheels, and distinctive sheetmetal, styling clues and badging accept always been amongst the many upgrades the S4 receives over its mainstream 100 and A4 siblings. In markets where the fifty-fifty higher-performance Audi RS 4 is not offered, the S4 is the pinnacle-of-the-line trim of the A4 family unit.[i] [2]
Like its regular A4 counterpart, all S4 variants have had longitudinally oriented, front-mounted engines. A single turbocharged 2.two-litre inline v-cylinder powered the original C4 version, and a 2.vii-litre twin turbocharged V6 engine was found in the B5 generation. The B6 and B7 versions shared a mutual 4.ii-litre V8 engine, the start time that a V8 engine was placed in a meaty executive car, placing it in direct competition with the BMW M3 and Mercedes-Benz C55 AMG which at the time had a 3.two L inline 6. The B8 generation uses a supercharged 3.0-litre V6 TFSI engine and competes with the both BMW 335i and BMW 335i/340i xDrive, and Mercedes-Benz C350.[one] The recently introduced B9 generation is powered past a turbocharged 3.0-litre V6 TFSI engine, every bit opposed to a supercharger like in the previous iteration. This current generation competes with the BMW M340i xDrive and Mercedes-Benz C450 AMG/Mercedes-AMG C43 4MATIC.[3] [4]
All versions of the S4 have their transmission mounted immediately at the rear of the engine in a longitudinal orientation, in the grade of a transaxle, and like all Audi "S" cars, are only available equally standard with Audi'due south quattro all-bike bulldoze (AWD) system, using a Torsen-based centre differential system.[five]
All versions of the S4 accept been manufactured at Audi'due south plant in Ingolstadt, Germany; they are, or have been available equally a four-door 5-seat saloon and a five-door 5-seat Avant (Audi's name for an manor automobile/station wagon) body styles since 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 congenital off the A5 coupe trunk style and the "South" variant is marketed under the Audi S5 nameplate.

Manufactory product of the original Audi S4 ( Typ 4A), usually known as Audi 100 S4, began in Baronial 1991 to serve as the performance version of the newly updated C4 platform 100 four-door, five-seat saloon. It was designed to replace the approachable C3 based Audi 200 quattro turbo, which had been Audi'southward first true sports-saloon and had been discontinued at the finish of 1990.[6] [7] Being the offset S4 model from Audi, it is commonly referred to every bit the Ur-S4, derived from the German: Ursprünglich 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 equally the Audi A6. In line with the switch in model proper name, Audi temporarily discontinued the utilize of the S4 name and began selling an updated merely fundamentally identical version of the machine, based on the "new" A6 and badged as S6. Despite the modify in proper noun, differences betwixt the outgoing S4 and incoming S6 were primarily cosmetic.
A more powerful, more expensive and more exclusive variant known first every bit the S4 Plus and after as the S6 Plus was available from October 1992 through to July 1994.[five] Built in very modest numbers, the "Plus" models featured numerous functioning enhancing upgrades; including the apply of Audi's iv.2-litre V8 engine in place of the and then electric current inline-five engine.
An all-new C5-based Audi A6 debuted for 1997, subsequently which the S4 and S6 became distinctly dissever models based on very different platforms.
The C4 variant S4 ended manufacturing plant production after less than 3 years in July 1994.[5]
One of its almost renowned owners was Ayrton Senna who owned a argent Avant,[8] non to the lowest degree considering he was the Audi distributor for Brazil.
C4 powertrain [edit]
In standard form, the powertrain item of the C4-based S4 was available with only one engine, a single turbocharged and intercooled version of Audi's ii.ii-litre 20-valve inline v-cylinder engine This displaced 2,226 cubic centimetres (135.8 cu in) and was equipped with an advanced Bosch Motronic electronic engine control unit (ECU).[5] This engine (parts code prefix: 034, identification code: AAN), developed a motive ability output of 169 kilowatts (230 PS; 227 bhp) at 5,900 revolutions per minute (rpm) and 350 newton-metres (258 lbf⋅ft) of torque one,950 rpm.[5] This powerplant fabricated it rather powerful by contemporary standards, and the vehicle with v-speed manual transmission was able to accelerate from standstill to 100 kilometres per hr (62.1 mph) in half dozen.2 seconds.
Both v- and vi-speed transmission transmissions (parts code prefix: 01E, identification codes: v-speed: CBD, CET, six-speed: CBL, CMG) were offered to European customers, but a five-speed transmission was the simply manual available in Northward America; a four-speed automatic manual (parts code prefix: 01F, identification lawmaking: CBF) was bachelor equally an option worldwide.[5] Forepart and rear axle final drive ratio is either 4.111 or 3.889 (dependent on transmission type), and the rear axle (parts lawmaking prefix: 017, identification codes: AAT, AET) uses a commuter-selectable electro-pneumatic-mechanical switchable diff lock.[five]
Audi's quattro four-wheel-bulldoze system was standard on the C4 S4/S6; a first-generation Torsen-based system which used the "T-one" automatically biasing centre differential (ATB) was used on vehicles equipped with transmission transmissions, while a transfer box based system was used on vehicles equipped with an automatic manual.[5]
S4/S6 "Plus" models equipped with a 4.2-litre 206 kilowatts (280 PS; 276 bhp) all-aluminium blend V8 engine (parts code prefix: 077, identification lawmaking: ABH) became bachelor to European customers as an option from October 1992, simply with the 6-speed manual gearbox, in either saloon or Avant body styles.[5]
C4 steering, brakes, wheels & tires [edit]
All C4 S4s' came equipped as standard with a conventional stock-still-help rack and pinion ability assisted steering (PAS) system. An electronically controlled 'servotronic' system, which varied the level of assist in accordance with the road speed, was available every bit an choice.[5]
At that place were two unlike types of high performance brake systems on offering for the C4 S4.[5] All S4s' initially had 310 mm (12.xx in) diameter past 25 mm (0.984 in) thick, radially ventilated disc brakes upward front end, each with an ATE single-piston sliding caliper inside a 'UFO' styled bell-shaped disc. With the introduction of the V8 engine, a new front brake setup became standard; again the discs used radial ventilation, but these front discs were now sized at 314 mm (12.36 in) by 30 mm (1.181 in) - with a conventionally mounted Lucas-Girling caliper in an external position over the disc. Usa models had smaller 276 mm (10.87 in) discs. The rear brakes, 269 mm (ten.59 in) by 20 mm (0.787 in) and also radially ventilated - remained the same throughout C4 production; they used a Lucas-Girling unmarried-piston sliding caliper with an integrated cable-actuated handbrake mechanism. A Bosch iii-aqueduct operation (iv-channel sensing) Anti-lock Braking Organization (ABS) with a mechanical load sensing valve for the rear brakes was standard throughout production.[5]
For bicycle options, the standard five-arm "Fuchs" forged alloy wheels were 8.0Jx16H2 ET40, and were shod with 225/50 R16 sized tyres. Several other tyre and bike designs were optionally available: a seven.5Jx15H2 ET40 six-spoke with 215/threescore R15 tyres, an 8.0Jx16H2 ET40 five-double-spoke, a 7.5Jx16H2 ET35 six spoke "Avus", and an viii.0Jx17H2 ET40 ten-spoke.[v]

The second generation S4 ( Type 8D), also known as the Audi S4 quattro debuted in 1997, with factory production commencing Oct 1997,[5] as part of the facelifted B5 platform Audi A4 line-up, although it wasn't available in N America until late 1999.
In addition to the saloon (sedan), an estate version (wagon)–the Audi S4 Avant–was introduced into the lineup from 1998. Production of the B5 S4 ceased in September 2001,[5] although it was withal sold together with the next B6 platform generation through 2002 in N America. Examples produced July 2001 to terminate of production are 2002 Model Year cars, the 10th digit of the VIN being the number "ii".
Several years after it was sold new, the B5 S4 remains a potent enthusiast motorcar, and as featured in the Dec 2007 effect of Sport Compact Auto magazine, a Torque Factory tuned S4 won a comparing test against several other extreme operation cars.[nine]
B5 powertrain [edit]
The powertrain details[5] of the B5 S4 feature a 2.7-litre twin-turbo ('biturbo') 90° third-generation V6 engine (parts lawmaking prefix: 078, identification codes: AGB, AZB, APB). Details of the powerplant include a bandage fe cylinder block with ii lightweight aluminium alloy cylinder heads. The valvetrain includes 30 valves (five valves per cylinder),[ten] [11] twin hybrid-driven (timing chugalug and roller concatenation) double overhead camshafts and variable valve timing for the inlet valves. The intake air is pressurized by 2 parallel h2o-cooled BorgWarner K03-series turbochargers; the charged air is cooled by ii side-mounted air-to-air intercoolers (SMICs). It displaces 2,671 cubic centimetres (163.0 cu in), and is rated to produce a motive power output of 195 kW (265 PS; 261 bhp) at v,800 rpm, and generates 400 N⋅m (295 lbf⋅ft) of torque at i,850 rpm. Engine management was by way of a Bosch Motronic ME 7.i (7.0 in North America) electronic engine command unit (ECU), and helped it meet the European EU-3D emissions standard. In all US-market cars, the engine was detuned to meet US emissions regulations; output was reduced to 184 kW (250 PS; 247 hp) and 350 N⋅m (258 lbf⋅ft) (identification lawmaking: APB).
As in the previous S4, a half dozen-speed C90 manual transmission (parts lawmaking prefix: 01E, identification code: DSY, gear ratios: 1st: 3.500, 2nd: 1.889, tertiary: 1.231, 4th: 0.967, 5th: 0.806, sixth: 0.684) was standard equipment, as was the Torsen T-2 quattro permanent all-wheel drive arrangement. Final bulldoze (parts code prefix: 01H, identification code: DQA) ratio is four.111. A 5-speed ZF 5HP19 tiptronic automatic transmission (parts lawmaking prefix: 01V) became available for the first fourth dimension every bit an option.[v]
The B5 S4 claims dispatch from 0 to 100 km/h (0.0 to 62.1 mph) in 5.7 seconds, and has an electronically limited top speed of 250 km/h (155.3 mph), making it both the quickest saloon/sedan in the Audi model line, and amid the quickest saloon/sedans in the earth at that time.[ citation needed ]
B5 suspension, brakes, wheels & tires [edit]
The B5 S4 is fitted with 4-cycle independent break. The front interruption is a multi-link design with 4 individual control arms per bicycle. The rear interruption is an unequal length double wishbone pattern; the lower control arms are mounted to a subframe which likewise carries the differential housing. Shock absorbers, curl springs, and anti-curl bars are fitted front and rear.
The B5 S4 restriction system[5] consisted of radially ventilated discs, 321 mm (12.64 in) in diameter by thirty mm (1.18 in) thick upward front, and 256 mm (10.08 in) by 22 mm (0.87 in) at the rear. Ii-piston Lucas HP2 brake calipers at the front (with four pads per caliper), with Lucas single-piston sliding brake calipers at the rear. A Bosch ABS 5.3 four-channel Anti-lock Braking Arrangement (with Electronic Brakeforce Distribution (EBD) and Electronic Differential Lock (EDL) - and later with ESP or Electronic Stability Programme), coupled with a vacuum servo completed the organization.
Standard wheels[5] were Audi's die-cast aluminium blend vi-arm 'Avus' 7.5Jx17H2 ET45 wheels, shod with 225/45 ZR17 performance tyres.
B5 colors & optional equipment [edit]
Bachelor outside colors included Brilliant Black, Laser Red, Light Silver, Cactus Light-green, Santorin Blueish, Hibiscus Blood-red, Casablanca White, Pearlescent White, Imola Yellow (spicy mustard), and Nogaro Blue. The last two colors were sectional to the S4 model. Interior leather was available in Onyx or Silver. Available options included:
- Bose premium sound system
- Audi Navigation Organisation
- 6-disc CD changer
- Hands gratis Motorola cellular phone
- Premium Package: Sunroof, HomeLink transmitter, Auto dimming mirrors
- Cold Weather Package: Heated front seats, Heated outside mirrors, Expandable ski sack
- Enhanced Sport Parcel: Alcantara seat inserts, Silver aluminum belt line trim or Carbon Fibre trim (on late 2000-2001 models), Aluminum mirror housings (on 2001 & 2002 models)
The Sport Bundle replaced the wood-grain chugalug line trim with silvery aluminum trim, and the wood grain cease 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 the early on 2000 models, the Alcantara inserts in the rear seats did non fully extend forrad to the front edge of the seat.
B5 motorsport [edit]
A motor racing version of the automobile achieved great success in the SpeedVision World Challenge with Michael Galati taking the 2001 SpeedVision GT championship in a Champion Racing S4, winning four races, and helping Audi to its first Manufacturers' Championship.
The Audi Sport specification Champion A4 chassis included a B5 RS4 engine, and Alcon racing brake calipers (4 piston front end and 2 piston rear calipers).
Don Istook, with Istook'due south Motorsports, built and campaigned several B5 S4's in first the Motorola Cup, and then the G Am Cup. The S4'due south were fifty-fifty raced past Istook's Motorsports in the Rolex GT category for several races to assist fill the field. Of annotation, one of the S4'southward, racing against truthful GT cars, even ran as high as 2nd place (in the pelting) at Barber Motorsports Park.[ citation needed ] These S4's were built using existing S4, not RS4 engines, just used the B5 Audi RS4 K04 turbochargers.

2003–2005 S4 (B6) saloon (US)
MY2003–2005 Audi S4 (B6) Avant (Canada)
The 3rd generation Audi S4 quattro ( Typ 8E — saloon: 8E2, Avant: 8E5, and Cabriolet: 8H7) debuted its saloon and Avant bodystyles in Europe in March 2003,[5] and appeared in Due north America slightly later.[ when? ] This was based on the latest Volkswagen Group B6 (PL46) platform used by the so electric current Audi B6 A4. Despite having moved to an entirely new platform, one of the S4'southward most publicised new features was its new engine - a 4.2-litre V8 engine. Post-obit its initial launch of either a iv-door v-seat saloon (sedan), or a five-door 5-seat Avant (manor/railroad vehicle), it eventually became available in iii bodystyles - and for the starting time time in the Audi 'Southward' car range, from February 2004, a 2-door four-seat Cabriolet (convertible), Typ 8H, was included in the model range.[12]
Official operation 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 five.8 s, Cabriolet 5.9 s), even so, a road test conducted by the American automotive mag Motor Trend [13] indicated that information technology could go from a standstill to 60 mph (96.six km/h) in less than 5 seconds, and arrive 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 U.s. gallon (11.6 L/100 km; 24.iii mpg‑imp)) for the six-speed transmission sedan in the U.s.a.. Top speed is electronically limited to 250 km/h (155.iii mph).
The B6 S4 saloon and Avant variants ceased factory production in December 2004, with the Cabriolet catastrophe twelve months later at December 2005.[five]
B6 powertrain [edit]
Replacing the 2.7-litre 'biturbo' V6 engine of the previous generation B5 S4, the new B6 S4 powertrain[five] gained an all-aluminium alloy 4.2-litre, 40 valve (v valves per cylinder) V8 engine (parts lawmaking prefix: 079.C, identification code: BBK), with concatenation-driven double overhead camshafts, roller-finger rocker arm cam followers, and included variable inlet camshaft timing. It likewise used a strengthened alloy crankshaft bedplate for the five master 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 the RS2 Avant, and nearly equally powerful every bit 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 command with the assist of four knock sensors. The exhaust arrangement includes vacuum-operated valves in the twin rear silencers (mufflers), finished with chrome plated tail-pipes.
Similar 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: ane.462, 4th: one.133, fifth: 0.919, sixth: 0.778),[5] with a 240 mm (ix.four in) single plate dry out clutch, and Torsen T-2 quattro permanent 4-wheel drive system. Concluding bulldoze (parts code prefix: 01R, identification code: EXZ) ratios are iii.889,[5] giving a peak gear road speed to engine revs ratio of 24.4 miles per hr (39.3 km/h) per 1000 rpm. From July 2003,[5] the ZF 6HP19 tiptronic automated transmission (parts lawmaking prefix: 09L, identification codes: GUR, HHU) (ratios - 1st: 4.171, second: 2.340, third: 1.521, fourth: i.143, 5th: 0.867, 6th: 0.691, with 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,[5] forth with 2 additional thermostatically-controlled side-mounted radiators.[v]
B6 steering, brakes, wheels & tyres [edit]
The B6 S4 came equipped with electronically controlled, variable assisted 'servotronic' rack and pinion power assisted steering (PAS) as standard.[five]
B6 S4 brakes[v] consisted of radially ventilated disc brakes front and rear. The front discs are sized at 345 mm (xiii.58 in) in bore by 30 mm (1.181 in) thick, and are clamped past 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 over again use unmarried-piston sliding calipers, with an integrated cable-operated hand brake mechanism. A Bosch ESP 5.seven Electronic Stability Plan 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 a dual-rate tandem vacuum servo provided the brake actuation.
Standard wheels[v] were 'Avus-3 die-cast aluminium alloy, viii.0Jx18H2 ET45 in size, and shod with 235/twoscore ZR18 95Y XL (eXtra Load) high performance tyres, with manufactory supplies being either Continental SportContact2 or Michelin PilotSport PS2.
B6 trunk & interior [edit]
Discrete lower door trims, along with the at present trademark Audi 'S' model vertical-accent line grille, and solid aluminium (after replaced with plastic covered by aluminium) exterior door mirrors, and S4 badging front and rear are all that visually distinguish the S4 from its related A4 brethren. In the interior, front and rear Recaro seats (fronts fully electric with the option of heated seats), as well as S4 logos in the instrument panel and door sills consummate the detail.

Audi S4 Sedan quattro (8EC, North America)
Audi S4 Cabriolet with optional seven-spoke alloy wheels (8HE, U.S.)
Audi S4 Avant quattro (8ED, Europe)
The Audi B7 platform Audi S4 quattro, based on the Audi B7 A4, debuted in belatedly 2004. Although Audi classifies it as a new car, the differences between information technology and the outgoing B6 S4 casually appear to exist primarily cosmetic, and is however classified by the internal designation: Typ 8E (although with revised sub-designations - saloon: 8EC, Avant: 8ED, and Cabriolet: 8HE).[5] Information technology has the same 4.two-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⋅thousand (302 lbf⋅ft) torque at 3,500 rpm.
There are a few mechanical changes, such every bit revised springs and dampers and, from model year 2007, an updated Torsen T-iii automatically biasing middle differential, featuring a 'default' asymmetric 40:60 front-rear torque split up on manual manual models, along with the afterward Bosch ESP 8.0 Electronic Stability Program[5] and gloss blackness painted brake calipers.[v] The 'Avus-Iii' wheels now became an option, and were replaced by a standard offering eight.0Jx18 inch 'S-design' 7-spoke forged alloy wheel.[5]
Bose sound system is now standard, whereas information technology was optional on the B6 S4, and an enhanced optional DVD-ROM-based RNS-East satellite navigation system replaces the previous CD-ROM-based RNS-D option.
The new trapezoidal unmarried-frame grille, Bi-Xenon high-intensity discharge lamp (HID) headlamps, L-shaped tail-lamps, quad exhaust tail pipes, and detached V8 badging below the side repeater indicators aid distinguish the B7 from the previous B6 model.
Audi S4 25quattro [edit]
Audi "S4 25quattro" special edition (8EC)
In June 2005,[five] Audi announced a limited edition run of 250 special edition S4 saloon cars, celebrating 25 years of quattro four cycle drive. This exclusive model was called the Audi S4 25quattro. Available just in the The states, the exterior has unique forepart and rear bumpers, a carbon fibre boot lip spoiler and lower forepart splitter, a rear functional crimson tow hook, and a high gloss Phantom Black painted grille with the "quattro" emblem. 15-spoke DTM blend wheels, along with optional dealer-fitted 'Audi four-rings' decals for the front doors complete the exterior makeover. Black and grey contrasting interior leathers, along with "quattro" embossed into the Recaro seats, together with a "i of 250" sectional quattro gear shift knob for the manual-only gearbox define the interior changes and act equally a subtle reminder of the exclusivity that the limited numbers command.
On the mechanical side, the S4 25quattro was the second Audi, subsequently the B7 RS4 to be fitted with the latest Torsen T-iii disproportionate ATB eye differential for its quattro permanent four-wheel drive organization. Under normal grip conditions, this is set with a default rearwards torque distribution bias of twoscore:60 front end to rear, and a maximum of 100% torque can automatically be apportioned to the rear axle (and up to eighty% to the front) as conditions warrant. The final bulldoze ratios are iii.889.

Audi S4 Sedan quattro (B8/8K, Australia)
Audi S4 Avant (B8/8K, S Africa)
From November 2008, the latest generation of the 'Audi S4 quattro'[14] ( Typ 8K) entered factory production. 0-sixty in 4 seconds. [5] It is based on the current Audi B8 A4,[15] congenital on the Volkswagen Group MLB/MLP platform. Unlike the previous B6 and B7 models, the new B8 version was just available as a four-door five-seat saloon (sedan), or a 5-door five-seat Avant (manor/wagon). The sport-functioning ii-door four-seat Cabriolet (convertible) drape is now taken past the electric current Audi S5 Cabriolet and new Coupe. Unlike previous generations of the S4, only the sedan will be imported to the United States and Canada.
Compared to the previous B6/B7 S4 which used a iv.2-litre V8 engine, this latest B8 S4 uses a smaller displacement 3.0-litre TFSI V6 engine, but at present with the addition of forced consecration via an Eaton mechanical supercharger.[1]
The previous B6/B7 S4s were the summit-of-the-line models in North America, alee of the 3.2L V6 and iv-cylinder 2.0T A4s, and competed with the BMW E46 330 and E90 335 respectively. The 3.0 TFSI V6 engine replaces the 3.2-litre FSI V6 as the upgrade engine in the A4 and A6 lineups starting for 2009; both the three.ii-litre FSI and three.0 TFSI were offered together until the end of the 2010 model year.[16] The 3.2L V6 engine is no longer offered in the A4 lineup from the 2011 model yr onwards, so the recently introduced B8 S4 is now priced 9% lower than its V8 predecessors, and slots directly to a higher place the 4-cylinder 2.0T base model. The S4 now compares more closely with the BMW 335i.
Previously unavailable enthusiast commuter aids are now optional, such every bit Audi's Sport Rear Differential, active steering and adaptive damping interruption (part of the Audi Drive Select Package). The forepart axle was moved by 6.1 inches to the front, which improved the weight distribution of the B8 Platform. Combined with the Sport Rear Differential Audi was able to profoundly improve the weight residuum and dynamics of the S4 over previous models.[17] [18] [19]
A new designed wheel is included on the B8 S4, an 8.5Jx18" '5-double-spoke Due south' design alloy bicycle with 245/40 ZR18 high performance tyres. Optional 19 inch bicycle and tyre packages are also available, sized at 8.5Jx19" alloy wheels with 255/35 ZR19 tyres. LED tail lights are standard fitment, along with Audi's now-trademark LED daytime running lights at the front.
The S4 along with the other B8 models received a facelift in early 2012. This included a revised front-end with new headlights and grille, an updated interior, and upgraded MMI options. Mechanically, the facelift B8 (known colloquially equally the B8.5) was upgraded with electromagnetic steering and a lighter crown gear center differential.
B8 powertrain [edit]
At the heart of the B8 S4 powertrain is an all-new, all aluminium-alloy iii.0-litre TFSI Supercharged (TFSI) V6 engine (parts code prefix: 06E, identification code: CAKA),[5] and similar the residuum of the B8 model range, now with Fuel Stratified Injection (FSI). This petrol engine displaces 2,995 cubic centimetres (182.8 cu in), and information technology is rated by Audi to a ability output of 245 kW (333 PS; 329 bhp) from 5,500 to 7,000 rpm. Torque is rated at 440 Northward⋅m (325 lbf⋅ft) from 2,900 to 5,300 rpm. This loftier power output is achieved past using forced consecration – and specifically, an all-new Eaton 'Twin Vortices Series' (TVS) Roots-blazon positive displacement compressor.[20] [21] This new supercharger features twin 4-lobe rotors, which are axially twisted 160 degrees. It is mounted on elevation of the engine, inside the 'Vee', pumping air direct into the inlet manifold, and incorporates 2 separate water-cooled intercoolers. This new design of supercharger is said to reduce the dissonance, vibration, and harshness (NVH) of the engine.
This engine is mated to either a six-speed manual manual (identification code: KMR)[v] or a vii-speed 'Southward tronic' DL501[22] dual clutch transmission[23] (identification lawmaking: LHK),[5] the latter with steering wheel mounted paddle-shifters for tiptronic gear selection, which replaces the Tiptronic automated transmissions institute in the B6/B7 iterations. The 'Audi quattro Sports differential' fitted in the rear axle final bulldoze unit is bachelor as an option.
Acceleration from a standstill to 100 km/h (62.1 mph) takes 5.1 seconds[24] for the saloon with transmission gearbox, the Avant one tenth of a second slower at 5.ii seconds. The same nuance to 100 km/h (62 mph) in the saloon with S tronic takes 5.iii seconds, and the Avant at 5.4 seconds. The top speed is electronically limited to 250 km/h (155.3 mph). However, a comparing in the American automotive magazine Road & Track [25] showed the sprint from 0 to 60 mph (97 km/h) in four.v seconds for the half-dozen-speed manual transmission. With figures like these, the B8 S4 accelerates more apace than its V8-engined predecessors.[ane] Audi of America claims that the version of the S4 achieves 28 highway miles per gallon, and a 0 to threescore mph (96.6 km/h) dispatch time of four.ix seconds with the transmission manual[26] and 5.i seconds with the S tronic.[27] Fuel consumption is rated at a combined 24.2 miles per Us gallon (9.vii L/100 km; 29.1 mpg‑imp).[24] Therefore, the B8 S4, unlike the V8-powered B6/vii models, avoids the US gas guzzler tax. The B8 S4's 3.0 TFSI engine also gets merely 1 thou.p.grand. less than the base 2.0 TFSI engine.[28] This is one of the most of import reasons for Audi to downsize their engines, while keeping the output equivalent better, by using forced-induction such as supercharging or turbocharging.[1]
The same engine is shared with the Audi S5 Cabriolet (though the 7-speed S Tronic is the sole transmission) and the 2013 Audi S5 Coupe. Detuned versions of this engine making 310 PS (228 kW; 306 hp) are plant in the 2009-11 Audi A6 3.0 TFSI (C6) mated to a half-dozen-speed TipTronic automatic transmission, the 2012 Audi A6 3.0 TFSI (C7) and 2012 Audi A7 3.0 TFSI, the latter ii which are paired with an viii-speed TipTronic automated.

Audi appear the B9 S4 in 2015, with the official unveiling of the European-spec model at the 2015 Frankfurt Motor Show. Noticeable changes to the B9 included a modern, more angular outside, newly designed wheels, and a new turbocharged V6 engine. Unlike the pre-facelift B8 S4, the announced European-spec model is but available with an viii-speed torque converter automatic (ZF 8HP55a).
Audi S4 Avant quattro 3.0 TFSI (United kingdom)
Audi S4 Avant facelift (Federal republic of germany)
The new model uses LED main-axle and LED daytime running lights equally standard, alongside dynamic turn signals and LED tail-lights. Like other Audi models, the notable feature in the new S4 is Virtual Cockpit which has Classic Layout and Sports Layout in displaying speedometer and tachometer.
The B9 S4 features standard 18-inch 5 double-spoke wheels with summertime tires, or optional 19-inch 5 V-spoke wheels.
The B9's brakes apply multi-piston calipers, replacing the single-piston sliding calipers of before models. LED headlights are standard while a apartment-bottomed steering wheel, "South" embossed seats, and quad tailpipes differentiate the S4 from the B9 A4.
B9 powertrain [edit]
The current generation S4 is powered by a 3.0 50 V6 with petrol direct injection and a single twin-scroll turbo powering the EA839 engine with 354 PS (260 kW; 349 hp) and 500 Northward⋅g (369 lbf⋅ft). The engine uses a hot inside V layout, which places the cylinder caput exhaust ports, exhaust manifolds, and turbocharger inside the V of the engine; this is a similar arrangement to the twin-turbo V8 engines used in Audi's C7/C8 RS6 and RS7 (including C7 S6/S7).
As a result of the powertrain upgrades in the new S4, it at present can accelerate from 0 to 60 mph (97 km/h) in iv.2 seconds.[30] It is electronically limited to a summit speed of 155 mph (249 km/h).[31]
In European markets, the facelifted B9 S4 - launched in 2019 - is at present powered by a 3.0-litre turbocharged diesel V6 with 347 PS (255 kW; 342 hp) and 700 N⋅m (516 lbf⋅ft), mated to a ZF 8-speed torque converter automatic gearbox and all-wheel-drive. For exterior of European markets, however, it nonetheless retains the 3.0-litre petrol turbo V6.
