2007 Audi RS4

The brand new Audi RS4 carries an impressive set of statistics: 420 bhp, 317 lb/ft peak torque, optional 19-inch wheels, 308 mm brakes, each with eight pistons, 0-62 mph in less than 5 seconds, and a top speed (without the electronic limiter) of around 300 km/h. Its credentials are cemented by its track performance – a Nurburgring lap time of 8 minutes 14 seconds, representing an impressive time for any sports car, let alone a four-seater sedan.

The figures are hard to escape – the Audi RS4 is a quick car. In fact, it is extremely quick – even quicker than the Audi S6 V10 model. The enormous tyres create exceptional grip in cornering, and its brakes are immensely efficient and effective at reigning in its enormous power. Yet these impressive facts and figures are only part of what makes the Audi RS4 an exceptional driving machine.

The styling and design have a huge role to play in making this feel like a truly special vehicle. It is, of course, based on the A4 shape but, in practice, it shares only its roof and front doors with the standard model. The muscular front and rear wheel arches, the enormous grille and front air intakes, and integrated rear spoiler are all extra features which make the RS4 stand out above its more common siblings.

In contrast with the S6, another of Audi’s premium models, the RS4 is not built on a standard Audi assembly line. Once the enormous 4.2-litre V8 engine and 6-speed gearbox have been fitted at Audi’s standard production facility, the 75%-completed RS4 is transferred to Quattro’s Neckarsulm facility, where the aerodynamics, huge wheels, suspension system and RS interior are fitted. The latter includes a unique steering wheel, carbon-fibre interior finish and the full range of electronic gadgets which would normally be costly extras on a standard A4.

Due to safety regulations, there will be some differences between the European and North American versions of the model. The European flat-bottomed steering wheel, for example, will be absent in the North American version, as will the adjustable seat bolsters and racing harness apertures – all due to North American airbag requirements.

Of course, the advanced technology and styling of the RS4 does come at a price – particularly in terms of practicality. The already compact rear seating allowance in the standard A4 is further compromised by the enormous front seats, and really only offers accommodation for children. The integration of advanced electronic systems into the cramped A4 dash results in some of the controls sitting on the passenger side of the car. In Sport mode, the accelerator pedal is so responsive that controlling the RS4 in slow traffic can be tricky. Yet these inconveniences are more than an acceptable price to pay for what is a truly incredible sports machine.
