The Audi B5 RS4 was introduced by Audi in late 1999, as the successor to the Audi RS2 Avant. The vehicle, like its RS2 predecessor, was available only as an Avant and was built on an existing platform, in this case the Volkswagen Group B5 platform shared with the A4 and S4. Although related to the Audi B5 S4, many of the outer body panels were altered, with wider front and rear wheel arches to allow for the wider axle track on the RS4. With unique front and rear bumpers and side sills and the rear spoiler from the S4 Avant not only did the RS4 look the part but the aerodynamic modifications achieved a drag coefficient of Cd 0.34.

The engine was developed from the 2.7 litre 90° V6 ‘biturbo’ used in the B5 S4. It displaced 2,671 cubic centimetres and had five valves per cylinder. This engine was developed and manufactured in the UK by Cosworth Technology. It featured enlarged intake and smaller exhaust ports on the two Cosworth cast aluminium alloy cylinder heads, two parallel BorgWarner K04-series turbochargers, two larger side-mounted intercoolers, dished piston crowns, stronger connecting rods, larger intake ducting, enlarged exhaust system and a re-calibrated engine management system. The modifications increased the engine’s output from 261 bhp and 295 lbft of torque in S4 to a mighty 375 bhp 325 lbft of torque.

Even with a kerb weight weight of 1,620 kilograms the RS4′s powerful engine gave it exhilarating performance with 60mph coming up in 4.9 seconds. Top speed was electronically limited to 162.8 mph.

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 discs, 360 millimetres diameter and 32 millimetres thick with double-piston floating calipers and at the rear 312 millimeters by 22 millimetres discs with a single-piston floating caliper. The RS4 needed less than 50 metres to come to a full stop from a speed of 68mph.

Audi produced 6,030 units between 1999 and 2001 of which only approxmately 400 examples were RHD.

This low-mileage example of Audi’s B5 RS4 Estate, presented in Avus Silver is in excellent condition. The paint work displays a deep shine with a metallic flake present making it sparkle under the studio lights. It looks fantastic with the wider front and rear wheel arches, unique, ground-hugging front and rear bumpers and side sills, and rear spoiler all contributing to a distinctive aggressive stance on the road.

RS4 badges front and rear help hint at it’s disguised super car underpinnings packed into a usable and daily vehicle, it’s not all about the power – a large boot and roof rails mean the car is also eminently practical.


Inside, the car is immaculate, with a subtle Quattro badge on the dash and a RS4 badge on the leather steering wheel. The front Recaro sports seats, clad in unmarked leather and supportive Hi Tech fabric, offer supreme comfort and grip assisted by an arm rest, pristine carpets and digital climate control.
