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 3 out of 5 Buying used RS models have something of a cult following, so the RS4 will hold its value better than most £50,000 cars.
