2018 Audi RS4 Avant at the IAA 2017 Overview Manufacturer (a private subsidiary of ) Production 1999–present Assembly, Body and chassis series Related The Audi RS4 quattro is the top tier and highest performing version of some specific generations of the range of automobiles. It is a (often called in some countries ), produced by Audi's high-performance private subsidiary, in limited numbers, for German car manufacturer AUDI AG, part of the larger. It slots distinctly above the, as the fastest, most sports-focused model based on the A4's. The RS 4 made a comeback in 2012, in Avant form only based on the Avant. The original version was produced only as a five-door five-seat 'Avant', Audi's name for an. The second version, the, was released initially as a four-door five-seat, with the Avant following a short while later.

A two-door four-seat version was subsequently added. Furthermore, their unique internal combustion engines are all, and are oriented. The is mounted immediately at the rear of the engine in a longitudinal orientation, in the form of a, and contains both a center and front.

The 'RS' initials are taken from the: RennSport—literally translated as 'racing sport', and is the Audi 's highest trim level, positioned above the model specification of Audi's regular model line-up. Like all, the RS4 pioneers some of Audi's latest advanced technology, and could therefore be described as a 'halo vehicle'. Furthermore, it is only available with Audi's -based 'trademark' permanent system.

Its main market competitors include the, C63,. Audi RS4 Avant (UK) The original B5 Audi RS4 Avant quattro ( Typ 8D) was introduced by Audi in late 1999, for main production and sale from 2000, as the successor to the / quattro GmbH joint venture-developed. The vehicle, like its RS2 predecessor, was available only as an Avant and was built on an existing platform, in this case the shared with the.

Retail price was around 103,584. The RS 4 was available for sale in most of Europe, parts of Asia and in some Latin American countries. Audi produced 6,030 units between 1999 and 2001.

B5 bodywork and styling Although related to the, many of the outer body panels were altered, with wider front and rear, to allow for the wider on the RS4. With unique front and rear bumpers and side sills, and the rear from the S4 Avant, the modifications achieved a of C d 0.34. Although the B5 S4 came in a saloon, the B5 RS4 was only available in the Avant version.

Luggage space, measured according to the industry standard VDA method was 390 litres (13.8 cu ft) with the rear seats in the upright position, and 1,250 litres (44.1 cu ft) with the seats folded flat. B5 powertrain. Audi B5 RS4 engine (red) and (blue) curves The engine was developed from the 90° V6 used in the.

It displaced 2,671 cubic centimetres (163.0 cu in) and had five valves per cylinder. The parts code prefix was 078 and the were: early version, 2000 (EU2 compliant): ASJ, and later version, 2000-01 (to EU3 standard): AZR. This engine was developed and manufactured in the UK by (now known as ). It featured enlarged intake and smaller exhaust ports on the two Cosworth cast aluminium alloy ALSi7mg, two K04-series, two larger side-mounted (SMICs), dished piston crowns, stronger connecting rods, larger intake ducting, enlarged, and a re-calibrated engine management system. The modifications increased the engine's output from 195 kW (265 PS; 261 bhp) and 400 N⋅m (295 lbf⋅ft) of in S4 form to 280 kW (381 PS; 375 bhp) at 7,000 rpm and 440 N⋅m (325 lbf⋅ft) at 6,000 rpm.

The engine was controlled by a ME 7.1 electronic (ECU), using a Bosch 'E-Gas' electronic throttle. It had multipoint sequential, a, six individual and longlife spark plugs. The engine oil was cooled by a dual oil:water cooler and an oil:air cooler. A six-speed (parts code prefix: 01E, identification code: FDP) (—1st: 3.500, 2nd: 1.889, 3rd: 1.320, 4th: 1.034, 5th: 0.806, 6th: 0.684), cooled by a in the engine undertray, and Audi's -based quattro system, using the Torsen T-1 'automatic torque biasing' (ATB) center, with a 50:50 default bias were standard. Final drive ratio was 4.111.

The RS4 has a of 1,620 kg (3,571 lb). It can accelerate from 0-100 km/h (62.1 mph) in 4.9 seconds, 0-160 km/h (99.4 mph) in 11.3 seconds, and 0-200 km/h (124.3 mph) in 17.0 seconds. Top speed was electronically limited to 262 km/h (162.8 mph). B5 brakes, wheels and tires Brakes were also developed jointly in house by Audi's quattro GmbH, not by Porsche as with its predecessor, the RS2.

At the front they were radially vented and floating cast iron, 360 mm (14.2 in) diameter and 32 mm (1.26 in) thick, with double-piston floating, and at the rear 312 mm (12.3 in) by 22 mm (0.87 in) discs with a single-piston floating caliper. The RS4 needed less than 50 metres (160 ft) to come to a full stop from a speed of 110 km/h (68 mph). The standard wheels were 18 inch (8½×18' '9-spoke'), with 255/35 ZR18 high performance tyres.

Optional 'winter' alloy wheels were also available, at 18 inch (7½J×18'), with 225/40 R18 92V tyres. Other B5 notable features.

However, after a long hiatus, the second Audi RS4 quattro ( Typ 8E), was built on Audi's, by quattro GmbH in, Germany. It was unveiled in February 2005 at Audi's 'quattro Night' celebration at the company headquarters in, Germany. The RS4 became available to European customers in mid-2006. It was introduced at the 2006 in January, and arrived in June 2006 in North America.

The production run of the B7 RS 4 was 2006 to 2008 inclusive, although only 2007 and 2008 model year were sold in the United States. To date, approximately 10,000 B7 RS4s have been built, of which around 2,000 are in the USA. The B7 RS4 Cabriolet, available in Europe from late 2006 to 2008, was made available as a model year 2008 vehicle in the USA in limited numbers per year (approx 300 total imported)and sold at a premium of $2000 over list. Audi factory numbers indicate that the B7 RS4 saloon can accelerate from 0 to 100 km/h (0 to 62 mph) in 4.8 seconds, and arrive at 0 to 200 km/h (0 to 124 mph) in 16.6 seconds. Most European magazines recorded results in line with the November 2009 comparison of 'ultimate sedans', in, which recorded a 0 to 60 mph time of 4.5 seconds. This is consistent with the pattern of conservatism that is usually found in Audi's official performance numbers. For the Avant, 0 to 100 km/h (0 to 62 mph) is reached in 4.9 seconds.

Top speed for all variants is 'officially' electronically limited to 250 km/h (155.3 mph), though some owners have reported that the speed limiter is rather 'liberal', conforming to the pattern of previous, with genuine top speeds of 270 km/h (168 mph) being recorded. B7 bodywork and styling. Audi RS4 Avant The B7 RS4 is an almost complete departure from previous, as it was initially available as a four- five-; with a five-door five-seat Avant , and two-door four-seat Cabriolet versions arriving later.

Only the had taken this similar route (saloon and Avant) before; the previous RS4 and were available exclusively as Avants. Constructed from fully steel in a (unitary/unibody) design, the B7 RS4 uses lightweight aluminium for its front (fenders) and (hood). The saloon version features a (C d) of 0.31, from a frontal area of 2.17 m 2. Like its B5 predecessor, visually, the B7 RS4 differs from its related, by having even wider flared front and rear, to allow for a wider. Over the, it also includes two larger frontal side air intakes (for the two additional side-mounted coolant ).

The trim on the saloon and roof rails on the estate are chrome as standard but can also be found in black with the addition of the Optic Pack which includes a black front grill, all exterior trim and black roof rails on the estate version. The B7 RS4 also includes an optional to complement the standard 'Xenon Plus' (HID) headlamps, which swivel around corners in conjunction with movements. Also standard are (DRLs), found within the main headlamp housings, identical to its related and S4, and use a conventional tungsten filament bulb. An acoustic parking system with front and rear sensors is also a standard fitment.

Unique interior trims, along with a within the central Driver Information System (DIS), aluminium pedal caps and footrest, and RS 4 logos complete the look. In the saloon, luggage space, measured according to the VDA 'block method', is 460 litres (16.2 cu ft) with the rear seats in the upright position, and 720 to 833 litres (25.4 to 29.4 cu ft) with the seats folded flat (dependent on specification). For the Avant, 442 litres (15.6 cu ft) is available with the seats upright (under the retractable load cover), and 1,354 litres (47.8 cu ft) being available with the rear seats folded flat (loaded to the roofline). Of the saloon variant starts at 1,650 kg (3,638 lb) (dependent on specification). A ten-speaker sound system, with 190 watt output and automatic dynamic noise compensation (which replaces the 'GALA' found on earlier units), with 'Concert II' radio and single CD player is standard (ICE) equipment. Factory fitted ICE options to complement the standard BOSE include the 'Symphony II' system which features twin radio tuners, a single-slot loading six-CD changer and a player all integrated into a double-DIN sized unit. Navigation option is the RNS-E 'Audi Navigation System plus' DVD-ROM GPS, which includes a folding widescreen 6.5-inch screen, two -memory card readers, and -like logic control.

B7 interior safety To achieve maximum body stiffness with controlled deformation, the B7 RS4 features of major seams of the high-strength steel body shell, which helps improve overall structural rigidity, particularly in the 'passenger cell', over traditional methods. Two-stage driver and front seat passenger frontal are standard, as is Audi's 'sideguard' head protection curtain airbag system. This latter system completely covers all of the side windows, from the front ' to the rear 'C-' or 'D pillars'. The body-hugging shell-type RS race bucket seats (not available in North American markets), complete with electrically inflatable upper and lower side bolsters and adjustable lumbar support, are constructed so as not to need lower side airbags to comply with European crash safety standards. In North America, the only front seats available are the more traditional Recaro seats (identical to those in the B6 and B7 S4), which include lower side airbags; these were also available as a no-cost option in other markets. Lower side airbags are optional for the standard-fit Recaro rear seats.

Front, and outer rear seatbelts include pyrotechnic belt, whilst all belts include an excess load limit function. B7 powertrain The engine of the B7 RS4 is based on the existing all-alloy 4.2 L (4,163 cc) V8 from the, and shares many parts, and, with the 4.2 FSI in the. The engine includes new cylinder block construction, and is a highly reworked, high-revving variant ( at 8,000 rpm; of 8,250 rpm). The parts code and version is 079.D and the identification code is. The same engine base was used for the Audi R8 when Audi wanted to build their first supercar.

However, the camshaft drive system was moved to the front of the block for the mid-engine R8. The engine has increased crankcase breathing, a low-pressure fuel return system and a baffled oil sump, to prevent engine lubricant cavitation at high engine speeds and high-G cornering. It has four valves per cylinder (instead of five on the earlier variant) and two overhead camshafts on each cylinder bank (so it is 'quad cam') and these are driven by roller chains with variable valve timing for both inlet and exhaust camshafts, along with a cast magnesium alloy fixed tract length with adjustable tumble flaps (to improve low engine speed combustion).

On 98 (93 ) Super-Unleaded petrol it produces 309 kW (420 PS; 414 bhp) at 7,800 rpm giving it a specific power output of 74.2 kW (100.9 PS; 99.5 bhp) per litre. Based on a of 1,680 kg (3,704 lb), this results in a of 0.184 kW per kg. This engine also produces 430 N⋅m (317 lbf⋅ft) of at 5,500 rpm, 90 percent of the total torque being available between 2,250 and 7,600 rpm. (Using lower 95 RON (91 AKI) standard unleaded fuel slightly reduces engine output, and therefore performance, and slightly worsens fuel economy). Exhaust gas escapes through two '4-into-2-into-1' fan-branch alloy steel and four high-flow metallic sports, into twin oval tail pipes with integral dynamic valves. The engine is controlled by two MED 9.1 electronic (working as 'master' and 'slave', because of the high-revving nature of the engine), and uses Bosch 'E-Gas' (also known as ), comprising throttle device, accelerator-pedal module, and ECU.

The ignition system uses eight individual, using mapped direct ignition, with Bosch single iridium electrode or triple-electrode long-life spark plugs. Is monitored with the aid of four sensors.

The engine complies with the Euro4. The saloon version produces 322-329 grams of per kilometre (g/km), and the Avant starts from 324 g/km. A 6-speed (parts code: 0A3, identification codes: HLD, JMH) is the only transmission available. The are 1st: 3.667, 2nd: 2.211, 3rd: 1.520, 4th: 1.133, 5th: 0.919, 6th: 0.778. The Audi B7 RS4 was the only 'RS' Audi powered by a until the was presented at the 2010 Geneva Motor Show. The RS5 also uses a 4.2 litre high revving V8.

The RS5 also dropped the Getrag 6-speed manual in favour of a 7-speed. Quattro Another focus of the B7 RS 4 was on the introduction of the latest development of Audi's 'trademark' permanent system. This utilised the 'third generation' asymmetric/dynamic T-3 'automatic torque biasing' (ATB) centre, featuring a 'default' 40:60 front-to-rear torque split under normal conditions. Audi stressed that this would result in a more neutral response in corners, and a more dynamic driving experience. Also, a more aggressive Torque Bias Ratio (TBR) was used, and set to 4:1, as opposed to 2:1 (and later variants 3:1 TBR) on standard A4.

Audi Owners Manual

That means that one side of the differential can handle up to 80%, while the other side would have to only handle 20% of applied torque. Front and rear differentials are conventional 'open' types, with a final drive ratio of 4.111. Traction is assisted by way of Audi's 'Electronic Differential Lock' (EDL), which is a specific function of the ESP 8.0 system. EDL monitors the rotational speeds of the left and right wheels across an individual axle, and if one wheel should rotate faster than the other (exceeding the pre-defined parameters), indicating loss of traction, or 'wheel spin' on one wheel, the EDL applies the brakes to that individual spinning wheel, and thus results in transferring torque across the open differential to the wheel on the other side deemed to have grip, hence traction. Also included in the ESP 8.0 is 'Anti Slip Regulation' (ASR)—Audi's name for.

The result of all these features is that under normal circumstances (driving straight on dry or even wet road surfaces) the car never loses traction, even when accelerating at full throttle in the first gear. B7 suspension and steering. Audi B7 RS4 The B7 RS4 also incorporates Audi's 'Dynamic Ride Control' (DRC) 'Sports Suspension' mechanism. The (shock absorbers) are made for Audi by KW, and central reservoirs/valves made. In the RS4 suspension, a fluid hydraulic linkage between diagonally opposing front and rear suspension dampers (left front to right rear, and vice versa) is used to counteract vehicle pitch and roll. Lightweight magnesium/aluminium alloy multi-link suspension arms (four arm with virtual steering axis up front, and trapezoidal arm with unequal length track control arms at the rear) locate each hub/brake/roadwheel assembly in a controllable fashion, whilst minimising unsprung masses.

Lightweight hollow tubular are standard front and rear. Compared to standard models, the RS4 features a 30 mm (1.2 in) lower. An optional 'Sports Suspension Plus' lowers the car by a further 10 mm (0.4 in), and marginally further stiffens the damper rates.

Has also been increased over standard A4s; the front widened by 37 mm (1.5 in), to 1,559 mm (61.4 in) and the rear by 47 mm (1.9 in) to 1,569 mm (61.8 in). Speed sensitive ' variable-assistance electro-hydraulic (PAS) is controlled from a compact flat-bottomed, finished in perforated leather with mock-aluminium trim. The steering rack ratio is 13.1:1, and the is 11.1 metres (36.42 ft). B7 brakes, wheels and tyres The standard brakes on the RS4 are of two-piece construction. The cast iron discs are cross-drilled and radially ventilated and float on aluminium alloy disc hubs. The two-piece disc construction reduces unsprung mass and also reduces the transmission of heat generated by the brakes to the wheel bearings. The front discs are 365 mm (14.4 in) in diameter and 34 mm (1.34 in) thick, and use gloss black monoblock eight-opposed-piston fixed calipers from the but with Red/Silver 'RS4' logos.

These and the transmission are supplied with a cooling airflow directed from located in the engine front undertray. The rear brakes are drilled, vented and floating 324 mm (12.8 in) by 22 mm (0.87 in) iron discs, with gloss black - single piston floating calipers with an integrated mechanical mechanism. A lighter, and higher performing, 'Audi ceramic' front brake system was an option from 2007 onwards (and only with 19 inch wheels).

It comprised cross-drilled, radially vented and floating (C/SiC) composite discs, 380 mm (15.0 in) diameter and 38 mm (1.50 in) thick, with grey Brembo monoblock six-opposed-piston fixed aluminium alloy calipers. The discs have a much greater tolerance to thermal differences, virtually eliminating, and have a duration of five times greater than conventional iron discs. The ceramic brakes also reduce unsprung mass by around 50% and thereby improve steering response and overall handling. A specifically 'tuned' 'sport-biased' ESP 8.0 is standard, and includes (ABS) and (EBD), and (BA). This ESP system has three user-selectable settings: the standard default full protection mode, increased slip mode (which turns off the ASR and EDL), and ESP fully off.

A useful feature of the ESP 8.0 is 'disc wiping', whereby in wet weather the ESP system applies the brakes frequently but momentarily. This removes water from the disc and pad surfaces, and helps to maintain the braking performance of dry weather. This operation is undetectable by the driver. In the UK and Japan, the standard wheels are 19 inch ( 9Jx19' ET29 '7-arm double spoke') with 255/35 ZR19 96Y XL (eXtraLoad) high performance tyres. This 19' wheel and tyre package was an option for the North American, and some European markets.

Factory supplied tyres included SportContact 3, Pilot Sport PS2, or P-Zero Rosso — although many owners have questioned the load-carrying abilities of the Pirellis (from unexplained sidewall failures and dubious dynamic stability), opting for the more durable Michelins at replacement time. A no-cost option of 18 inch alloy wheels ( 8½Jx18' ET24 '5-spoke design' ) with 255/40 ZR18 Y XL tyres was also available, and these are standard in North American markets. A winter wheel and tire package was also available as an option, and included 245/40 R18 96V SP WinterSport 3D tyres.

A direct-acting (TPMS) is standard fitment. This system monitors the pressure in all four tyres every three seconds, and when any loss in pressure is detected, audible and visual warnings are given to alert the driver via the Driver Information System (DIS) in a timely manner. Other B7 notable features Other notable features to be found as standard equipment on cars for non-North American markets are the smaller, flat bottomed (complete with 'Sport' button)again selected from the VAG parts bin from the Lamborghini Gallardo like the brakes,however a standard 'multifunction' steering wheel was a no cost option, body-hugging shell-type race bucket seats complete with electrically inflatable upper and lower side bolsters. B7 crash testing The North American (IIHS) crash tested the B7 RS4's sibling, the B7 A4, and awarded it 'Double Best Pick' for frontal and side crashes—beating illustrious rivals such as the, the, however at the 2012 session of the SOT (small overlap test ) the A4 was rated Poor, rating applying up to the 2016 MY. B7 awards The Audi RS4 won 's Most Surprising Car of the Year in 2005. In 2007, the Audi RS4 was the winner in the 'World Performance Car' category of the International (WCOTY).

It beat rivals, including its larger sibling, the, the,. B8 (2012–2015). Motorsport Speed World Challenge The B7 RS4 was planned to replace the in the SCCA, but after Champion Racing had prepared the car, it was decided not to compete in the series, due to rule changes imposed by the (SCCA) on Audi concerning 4WD systems, wheels size, and engine power output. Rather than scrapping the fully built Speed World Challenge RS4, Champion and Audi used the car as a part of the American Le Mans Series Vitesse Program, which highlights the technology link between and conventional road cars. Euro Superstars Six RS4s are openly campaigned in the by Audi Sport Italia.
