Audi A4 RS4 (05-08) - Review Review by Simon Harris on 21 February 2006 Last Updated: 16 January 2009 Available as a saloon, estate and convertible, Audi's ultimate A4, the RS4, is powered by a huge 4.2-litre V8 engine with a whopping 414bhp. This gives it a 0-60mph time of less than five seconds and allied to a howling soundtrack from the FSI engine and four exhaust pipes, it makes driving one an intoxicating experience. The RS models have long had a cult following and this one is no exception. It's not cheap to buy or run, but if you want a less brash and overt alternative to the BMW M3, look no further. 5 out of 5 Other Audi reviews Summary Facts & Figures Equipment Driving & Performance Comfort Costs Safety & Reliability Buying & Selling Also Consider Company Car Info Owners' Reviews Gallery 4 out of 5 Safety This generation of the RS4 was not Euro NCAP crash tested, though the previous generation badged of the A4 – which is structurally similar – gained four stars. It comes with front, side and curtain airbags as standard with rear side airbags optional. Stability control is standard as are head restraints that help to counter whiplash. On the security front there is a Thatcham Category One alarm and immobiliser system fitted.

This one has a highly stressed engine (the rev limiter cuts in at 8250rpm) and must be maintained according to schedule to ensure it continues to perform as it should. The FSI engine is chain driven so won't need cambelts. Car check problem points Body No problems reported. Engine/Gearbox No problems reported. Other No problems reported.
