Contact: 301-356-1702 initial contact via text is preferred because I typically ignore calls from numbers I don't recognize. DM'ing me on here is fine too.

Current Dyno Numbers: 384 whp and 484 ft lbs on 93 octane with tuning revisions still ongoing. Car is an awesome candidate for Tial 770's, GT28's, or a Big Single Turbo. I built the engine and the rest of the car with the intent of going xr770's, but priorities have changed so it's time to move on. Not that it matters but I have north of $40,000 in parts receipts for this thing, nevermind labor.

Wheels/Tires:
*** -Car will come with two sets of wheels plus one full size spare. Nine wheels in total. All wheels are the oem 18x8 BBS CH from a B7 S4.
-The summer set is finished in dark hyper silver and has 225/40-18 continental extreme contact sport tires with 7-8/32” of tread depth left. No curb scrapes or any flaws for that matter to be noted.
-The winter set is finished in gloss black powder coat and has 225/40-18 bridgestone blizzak ws80 snow tires mounted. The tires have one season of use on them so I’d estimate 9-10/32” tread depth. They’re in my storage unit right now otherwise I’d go measure them. No curb damage or scrapes on this set either, but there are maybe 6-10 small rock chips between the four wheels.
-The ninth wheel is the original silver and currently located in the spare tire area in the trunk. It does have a curb scrape which is why it’s the spare.
-ECS Tuning 15mm wheel spacers on all four corners
-All the wheels are straight and true, no bends or cracks.
-VW Lug Bolt Covers

Body/Exterior:
-Sport package aluminum housing mirrors with auto dimming. Mirror glass is in good condition. Just replaced the passenger side mirror glass two months ago because the fluid leaked out of it.
-Windshield replaced when I got the car and is still free of cracks/chips.
-No exterior body modifications to note.
-New S4 trunk badge that went on shortly after I got the car. *
-Car is in good shape for it’s age. I think the pictures show that, but it’s not without flaw. It has the typical paint chips and dings you’d expect to find on an 18 year old car. There’s a scuff on the passenger side of the rear bumper that was filled in with touch up paint. Same thing with the door moulding on the drivers side front door and also a spot on the bottom of the front bumper on the drivers side. I’ve tried to keep any paint chips that pop up filled with touch up paint. I get plenty of compliments on how the car looks, especially when people find out how old it is.
-Paint was coated with Carpro Cquartz in December 2018.
-New OEM windshield wiper transmission Sept. 2018


Interior:
-Seats are in good shape, no tears or rips in the leather. ***
-Armrest is good too.
-Seat heaters are pretty much useless for their intended purpose. They get hot in a few select spots but not enough to really do much.
-Has typical b5 s4 headliner sag.
-Some fingernail marks on the soft touch paint on the interior door handles
-Woodgrain trim on the doors and dash but I replaced the hazard surround trim and the shifter trim with the sport package black trim.
-Pixels in the gauge cluster center display are partly dead.
-Dual gauge pod on the steering column. Left side has an aem x-series wideband that reads from the passenger downpipe and the right side has a podi boost gauge.
-I put in a new in dash cup holder when I got the car.
-Factory audi radio with a blitzsafe aux cable box.
-Sunroof works if you open and close it incrementally. I never used it beyond checking to see if it worked when I got the car.
-No water leaks.
-Complete factory jack tool kit in the trunk.
-Cold weather package car so it has the ski bag that comes out from the rear seat armrest. I know that’s a very important feature to nearly none of us.
-Tint job on the rear windshield isn’t the greatest but I wasn’t going to rip it off because the rear defroster still works.
-Has the audi all weather floor mats front and rear.
-RS4 perforated leather shift knob
-Driver and passenger power seats work in all directions
-Glovebox soft open feature still works
-All windows work and so does the one click up and down function.
-Central Locking System Works
-Key Fob Lock and Unlock Works
-No Check Engine Light. Hasn’t had one since the bugs were ironed out in the beginning.

Interesting 3.0 motor build thread...

westwest888:

First thread of this sort since the Eurocode built motor with special heads. 2 piece rods though?

How many pieces are rods usually?

The motor build should be interesting. I’m looking forward to that part of this for sure…

I have mixed feelings about the twin-charged setup (even taking Solo/JFonz out of the equation). It’s one of those things that probably makes perfect sense until you have to actually make it all work together. In theory, I think it would be a good setup. The TVS supercharger’s low end punch is a good match with a larger single turbo’s lag and upper end potential. You’d get the best of both. In reality, heat is already a major issue at stage 2 levels, and adding in hot compressed air from a turbo to the (TVS) heat pump that already sits on top of our motor is a tough thing to deal with. It definitely creates a lot of cooling and tuning issues that, I’m guessing, have been it’s downfall to this point. Built motor or not.

A twin tubo is another good idea in theory, but again reality has some challenges. The B8 chassis is an already tight package that has very little space. Then you have to add in the costs of two exhaust manifolds, an entirely new intake manifold, cooling, two turbos, etc. That just seems like it would get really expensive in the Audi world. I hate to even think what it would cost…

I don’t think a centrifugal supercharger would be a good match with the 3.0 TFSI without the TVS. The 3.0 TFSI without the TVS is, by design, pretty anemic down low. The boost on centrifugal superchargers (like Vortech) is in direct relation to RPM. Typically, it would work better on a car that already has a nice lower-RPM power band, and that goes away on the 3.0 TFSI without the TVS. Not to say it couldn’t work; it’s just probably not the best match for this engine without the TVS. If you keep both, that’s a lot of parasitic loss to deal with.

The above reasons are why I think APR started down the larger TVS path. That probably looked like the easiest upgrade path. Again, in theory at least, and we know how that has worked out. In reality, what probably makes the most sense is a more efficient twin screw style blower. Something like the Kenne Bell or similar. That could use the same packaging as the current TVS, but offer more efficiency at higher volume and boost levels.

words: Bill, photos: New German Performance and Classic Auto Mall

Audi B5 S4, whether sedan or Avant, have acquired almost legendary status amongst Audi fans and this one is no exception. Finding a well sorted out example that is not ragged or rusty is getting harder these days so when we saw our friends over at New German Performance (NGP) post this one, we took a closer look. It also didn’t hurt that the caption for their picture was this:

Our dear friend Karl is selling his big-turbo S4. This was a no-stone-unturned NGP build with that included fresh motor build, Tial 770 turbos, EPL tuning, and a host brand new factory and performance aftermarket hardware. Bumper to bumper- if we could replace it or make it better, we did.

Ok…you have our attention. We clicked on the link provided to find out more.

On the floor of our massive showroom we are now graced with the presence of our first Audi, and this one happens to be a very special German wolf in sheep clothing. Lots of modifications and this car is extremely fast and nimble. Many hours spent on performance, and it retains mostly its original look…fabulous!

Exterior
Draped in Brilliant Black, this car retains all of its original look. Integrated bumpers, aerodynamically designed headlights, a rounded front grille, swept back windshield, and perfectly aligned doors and wrap around rear quarter lets you cut through any Passat (and that does not mean VW!). A snazzy sunroof retracts to let the sky in on the roof, and sexy 18-inch Enkei wheels adorn all 4 corners.

Interior
Making the other two seats jealous, a Recaro all leather all black bucket seat is reserved for the pilot. Others are left with a snazzy two-tone gray insert tuck and roll with black bolsters and not to be too outdone, in leather and suede. Vibrant red instruments glow on a black background in front of the original steering wheel. This has an Aquamist gauge to keep track of the twin turbos underneath the hood in front. In the center of the seats is a CAE German shifter, and just above a Bluetooth sound system this is only out shouted by the engine. The headliner which frames the sunroof is nice and tight above, and the black carpet which floods the floor is tidy with no stains or fading.

Drivetrain
You are going to want to stick around for this on. At a consigner stated 724hp this new 3.0 Liter V6 with twin Tial 770R turbos is a piece of German engineering jewelry that adorns the engine bay and sports a mere 8,000 plus miles on it since being installed. This engine has been ported and polished and started out as a 2.8 Liter CS with 30V heads. Electronic fuel injection works with the Tial 770R twin turbos to feed fuel and fossils to the mill at an alarming rate. A C90 6-speed transmission in manual form is strapped to the back of this healthy mill and pushes power back to a 4.11 rear. This only scratches the surface and a complete build sheet will come with the car detailing every move made with the ultimate intention to be to race this car in an SCCA class.

Undercarriage
Unbelievably clean and rust-free underneath, with not even a hint of surface rust on any structural part. Porsche Cayenne disc brakes are all around and beefed up independent suspension is all around. The bottom end of the engine shows nary a drip of any oil and is dry as a bone overall. Obviously well cared for.

Drive-Ability
When someone says race car, I say we shall see, and this car did not disappoint. Started right up and let me tell you for free it has plenty of power! The car handles very well, slides into turns nicely, and has great braking, which with 724 horses going to all four wheels is extremely important. A goer and a shower it has won multiple awards, and is a nice comfortable cruiser to boot. Just don’t let anyone fool with you or they will be very sorry.

This is German engineering on steroids, with its Recaro seat, healthy re-engineered mill, Tila racing shifter attached to the 6-speed, twin turbos, and Cayenne brakes we give you an Auto Union of parts that make up a respectable race car. Summit Point here we come!

Building an Audi A4 B9 in 10 minutes like THROTL!

Audi S4

Motor vehicle

The Audi S4 is the high performance variant of Audi's compact executive carA4. The original Audi S4, built from 1991 until 1994, was a performance-oriented version of Audi's 100saloon/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 suspension, larger wheels, and distinctive sheetmetal, styling clues and badging have always been amongst 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.[1][2]

Like its regular A4 counterpart, all S4 variants have had longitudinally oriented, front-mounted engines. A single turbocharged 2.2-litre inline five-cylinder powered the original C4 version, and a 2.7-litre twin turbochargedV6 engine was found in the B5 generation. The B6 and B7 versions shared 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 which at the time had a 3.2 L inline 6. The B8 generation uses a supercharged 3.0-litre V6 TFSI engine and competes with the BMW 335i.[1] The recently introduced B9 generation is powered by a turbocharged 3.0-litre V6 TFSI engine, as opposed to a supercharger like in the previous iteration.[3][4]

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.[5]

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 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 the performance version of the newly updated C4 platform 100 four-door, five-seat saloon. It was designed to replace the outgoing C3 based Audi 200 quattro turbo, which had been Audi's first true sports-saloon and had been discontinued at the end of 1990.[6][7] Being the first S4 model from Audi, it is commonly referred to as 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 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 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 primarily cosmetic.

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.[5] Built in very small numbers, the "Plus" models featured numerous performance enhancing upgrades; including 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.[5]

One of its most renowned owners was Ayrton Senna who owned a silver Avant,[8] not least because he was the Audi distributor for Brazil.

C4 powertrain[edit]

In standard form, the powertrain detail of the C4-based S4 was available with only one engine, a single turbocharged and intercooled version of Audi's 2.2-litre 20-valveinline five-cylinder engine This displaced 2,226 cubic centimetres (135.8 cu in) and was equipped with an advanced BoschMotronic electronic engine control unit (ECU).[5] This engine (parts code prefix: 034, identification code: AAN), developed a motive power output of 169 kilowatts (230 PS; 227 bhp) at 5,900 revolutions per minute (rpm) and 350 newton-metres (258 lbf⋅ft) of torque 1,950 rpm.[5] 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 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.[5] 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.[5]

Audi's quattro four-wheel-drive system was standard on the C4 S4/S6; a first-generation Torsen-based system which used the "T-1" automatically biasing centre differential (ATB) was used on vehicles equipped with manual transmissions, while a transfer box based system was used on vehicles equipped with an automatic transmission.[5]

S4/S6 "Plus" models equipped with a 4.2-litre 206 kilowatts (280 PS; 276 bhp) all-aluminium alloy V8 engine (parts code prefix: 077, identification code: ABH) became available to European customers as an option from October 1992, only with the six-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 fixed-assistance rack and pinion power assisted steering (PAS) system. An electronically controlled 'servotronic' system, which varied the level of assistance in accordance with the road speed, was available as an option.[5]

There were two different types of high performance brake systems on offer for the C4 S4.[5] All S4s' initially had 310 mm (12.20 in) diameter by 25 mm (0.984 in) thick, radially ventilated disc brakes up front, 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. 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 a mechanical load sensing valve for the rear brakes was standard throughout production.[5]

For wheel 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 wheel designs were optionally available: a 7.5Jx15H2 ET40 six-spoke with 215/60 R15 tyres, an 8.0Jx16H2 ET40 five-double-spoke, a 7.5Jx16H2 ET35 six spoke "Avus", and an 8.0Jx17H2 ET40 ten-spoke.[5]

The second generation S4 (Type 8D), also known as the Audi S4 quattro debuted in 1997, with factory production commencing October 1997,[5] as part of the facelifted B5 platformAudi A4 line-up, although it wasn't available in North 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 still sold together with the next B6 platform generation through 2002 in North America. Examples produced July 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 the December 2007 issue of Sport Compact Car magazine, a Torque Factory tuned S4 won a comparison test against several other extreme performance cars.[9]

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 code prefix: 078, identification codes: AGB, AZB, APB). Details of the powerplant include a cast ironcylinder block with two lightweight aluminium alloy cylinder heads. The valvetrain includes 30 valves (five valves per cylinder),[10][11] twin hybrid-driven (timing belt and roller chain) double overhead camshafts and variable valve timing for the inlet valves. The intake air is pressurized by two parallel water-cooled BorgWarner K03-series turbochargers; the charged air is cooled by two 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 5,800 rpm, and generates 400 N⋅m (295 lbf⋅ft) of torque at 1,850 rpm. Engine management was by way of a BoschMotronic ME 7.1 (7.0 in North America) electronic engine control 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 code: APB).

As in the previous S4, a six-speed C90 manual transmission (parts code prefix: 01E, identification code: DSY, gear ratios: 1st: 3.500, 2nd: 1.889, 3rd: 1.231, 4th: 0.967, 5th: 0.806, 6th: 0.684) was standard equipment, as was the Torsen T-2 quattro permanent all-wheel drive system. Final drive (parts code prefix: 01H, identification code: DQA) ratio is 4.111. A five-speed ZF5HP19tiptronicautomatic transmission (parts code prefix:01V) became available for the first time as an option.[5]

The B5 S4 claims acceleration from 0 to 100 km/h (0.0 to 62.1 mph) in 4.9 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 among the quickest saloon/sedans in the world at that time.[citation needed]

B5 suspension, brakes, wheels & tires[edit]

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 lengthdouble wishbone design; the lower control arms are mounted to a subframe which also carries the differential housing. Shock absorbers, coil springs, and anti-roll bars are fitted front and rear.

The B5 S4 brake system[5] 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 the rear. A Bosch ABS 5.3 four-channel Anti-lock Braking System (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 system.

Standard wheels[5] were Audi's die-cast aluminium alloy six-arm 'Avus' 7.5Jx17H2 ET45 wheels, shod with 225/45 ZR17 performance tyres.

B5 colors & optional equipment[edit]

Available exterior colors included Brilliant Black, Laser Red, Light Silver, Cactus Green, Santorin Blue, Hibiscus Red, Casablanca White, Pearlescent White, Imola Yellow (spicy mustard), and Nogaro Blue. The last two colors were exclusive to the S4 model. Interior leather was available in Onyx or Silver. Available options included:

  • Bose premium sound system
  • Audi Navigation System
  • 6-disc CD changer
  • Hands free Motorola cellular telephone
  • Premium Package: Sunroof, HomeLink transmitter, Auto dimming mirrors
  • Cold Weather Package: Heated front seats, Heated outside mirrors, Expandable ski sack
  • Enhanced Sport Package: 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 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 the early 2000 models, the Alcantara inserts in the rear seats did not fully extend forward to the front edge of the seat.

B5 motorsport[edit]

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 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 the rain) at Barber Motorsports Park.[citation needed] These S4's were built using existing S4, not RS4 engines, but used the B5 Audi RS4 K04 turbochargers.

2003–2005 S4 (B6) saloon (US)
MY2003–2005 Audi S4 (B6) Avant (Canada)

The third 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 North America slightly later.[when?] This was based on the latest Volkswagen Group B6 (PL46) platform used by 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, a two-door four-seat Cabriolet (convertible), Typ 8H, was included in the model range.[12]

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[13] indicated that it could go from 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 the six-speed manual sedan in the United States. Top speed is electronically limited to 250 km/h (155.3 mph).

The B6 S4 saloon and Avant variants ceased factory production in December 2004, with the Cabriolet ending twelve months later at December 2005.[5]

B6 powertrain[edit]

Replacing the 2.7-litre 'biturbo' V6 engine of the previous generation B5 S4, the new B6 S4 powertrain[5] 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 chain-driven double overhead camshafts, roller-finger rocker armcam followers, and included variable inlet camshaft timing. It also used 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 the RS2 Avant, and nearly as powerful as the B5 RS4. Engine management was by way of a BoschMotronic 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 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),[5] with 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,[5] 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,[5] the ZF 6HP19tiptronicautomatic 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 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 ampalternator,[5] along with two additional thermostatically-controlled side-mounted radiators.[5]

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.[5]

B6 S4 brakes[5] 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 a dual-rate tandem vacuum servo provided the brake actuation.

Standard wheels[5] were 'Avus-III die-cast aluminium alloy, 8.0Jx18H2 ET45 in size, and shod with 235/40 ZR18 95Y XL (eXtra Load) high performance tyres, with factory supplies being either Continental SportContact2 or Michelin PilotSport PS2.

B6 body & interior[edit]

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 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 complete the detail.

The Audi B7 platform Audi S4 quattro, based on the Audi B7 A4, debuted in late 2004. Although Audi classifies it as a new car, the differences between it and the outgoing B6 S4 casually appear to be primarily cosmetic, and is still classified by the internal designation: Typ 8E (although with revised sub-designations - saloon: 8EC, Avant: 8ED, and Cabriolet: 8HE).[5] 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 a 'default' asymmetric 40:60 front-rear torque split on manual transmission models, along with the later Bosch ESP 8.0 Electronic Stability Programme[5] and gloss black painted brake calipers.[5] 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.[5]

Bose sound system is now standard, whereas it was optional on 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-Xenonhigh-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.

Audi S4 25quattro[edit]

Audi "S4 25quattro" special edition (8EC)

In June 2005,[5] Audi announced 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 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 the B7 RS4 to be fitted with the latest Torsen T-3 asymmetric ATB centre differential for its quattro permanent four-wheel drive system. 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, the latest generation of the 'Audi S4 quattro'[14] (Typ 8K) entered factory production.[5] It is based on the current Audi B8 A4,[15] 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 is now taken by the 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 4.2-litre V8 engine, this latest 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.[1]

The previous B6/B7 S4s were the top-of-the-line models in North America, ahead of the 3.2L V6 and 4-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 3.2-litre FSI and 3.0 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 year onwards, so the recently introduced B8 S4 is now priced 9% lower than its V8 predecessors, and slots directly above the 4-cylinder 2.0T base model. The S4 now compares more closely with the BMW 335i.

Previously unavailable enthusiast driver aids are now optional, such as Audi's Sport Rear Differential, active steering and adaptive damping suspension (part of the Audi Drive Select Package). The front 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 greatly improve the weight balance 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 S' design alloy wheel with 245/40 ZR18 high performance tyres. Optional 19 inch wheel 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 as 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 3.0-litre TFSI Supercharged (TFSI)V6 engine (parts code prefix: 06E, identification code: CAKA),[5] and like the rest of the B8 model range, now with Fuel Stratified Injection (FSI). This petrol engine displaces 2,995 cubic centimetres (182.8 cu in), and it is rated by Audi to a power output of 245 kW (333 PS; 329 bhp) from 5,500 to 7,000 rpm. Torque is rated at 440 N⋅m (325 lbf⋅ft) from 2,900 to 5,300 rpm. This high power output is achieved by using forced induction – and specifically, an all-new Eaton'Twin Vortices Series' (TVS) Roots-type positive displacement compressor.[20][21] This new supercharger features twin four-lobe rotors, which are axially twisted 160 degrees. It is mounted on top of the engine, within the 'Vee', pumping air directly into the inlet manifold, and incorporates two separate water-cooledintercoolers. This new design of supercharger is said to reduce the noise, vibration, and harshness (NVH) of the engine.

This engine is mated to either a six-speed manual transmission (identification code: KMR)[5] or a seven-speed 'S tronic' DL501[22]dual clutch transmission[23] (identification code: LHK),[5] the latter with steering wheel mounted paddle-shifters for tiptronic gear selection, which replaces the Tiptronic automatic transmissions found in the B6/B7 iterations. The 'Audi quattro Sports differential' fitted in the rear axle final drive unit is available as an option.

Acceleration from a standstill to 100 km/h (62.1 mph) takes 5.1 seconds[24] for the saloon with manual gearbox, the Avant one tenth of a second slower at 5.2 seconds. The same dash to 100 km/h in the saloon with S tronic takes 5.3 seconds, and the Avant at 5.4 seconds. The top speed is electronically limited to 250 km/h (155.3 mph). However, a comparison in the American automotive magazine Road & Track[25] showed the sprint from 0 to 60 mph in 4.5 seconds for the 6-speed manual transmission. With figures like these, the B8 S4 accelerates more quickly than its V8-engined predecessors.[1] Audi of America claims that the version of the S4 achieves 28 highway miles per gallon, and a 0 to 60 mph (96.6 km/h) acceleration time of 4.9 seconds with the manual transmission[26] and 5.1 seconds with the S tronic.[27] Fuel consumption is rated at a combined 24.2 miles per US gallon (9.7 L/100 km; 29.1 mpg‑imp).[24] Therefore, the B8 S4, unlike the V8-powered B6/7 models, avoids the US gas guzzler tax. The B8 S4's 3.0 TFSI engine also gets only 1 m.p.g. less than the base 2.0 TFSI engine.[28] This is one of the most important 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 found in the 2009-11 Audi A6 3.0 TFSI (C6) mated to a 6-speed TipTronic automatic transmission, the 2012 Audi A6 3.0 TFSI (C7) and 2012 Audi A7 3.0 TFSI, the latter two which are paired with an 8-speed TipTronic automatic.

The new model uses LED main-beam and LED daytime running lights as 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 summer tires, or optional 19-inch 5 V-spoke wheels.

The B9's brakes use multi-piston calipers, replacing the single-piston sliding calipers of earlier models. LED headlights are standard while a flat-bottomed steering wheel, "S" embossed seats, and quad tailpipes differentiate the S4 from the B9 A4.

The current generation S4 is powered by a 3.0 L V6 with petrol direct injection and a single twin-scroll turbo powering the EA839 engine with 354 PS (260 kW; 349 hp) and 500 N⋅m (369 lbf⋅ft). The engine uses a hot inside V layout, which places the cylinder head 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 now can accelerate from 0 to 60 mph (97 km/h) in 4.2 seconds.[30] It is electronically limited to a top speed of 155 mph (249 km/h).[31]

In European markets, the facelifted B9 S4 - launched in 2019 - is now 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 outside of European markets, however, it still retains the 3.0-litre petrol turbo V6.
