Fast RS models have propagated throughout Audi’s range, but the Audi RS4 still holds a special place in the memory of enthusiasts.

The RS2 estate of 1994 was the first Audi to wear the RS badge, and it was a corking car to drive. It was succeeded by the second Audi RS model, the RS4, in 2000. That was less rewarding but incredibly usable, and really kick-started the RS spawning process. The RS4 of 2006, however, still shines brightest, and is remembered for its fluid ride, engaging handling and superb powertrain.

The RS4’s ability to find grip in the wet is almost without peer

There are some things you can predict about an RS Audi. That it will have monster performance and traction will be a given. That it will retain all the interior furnishings of its lesser siblings is taken as read, too.

But just what kind of dynamic demeanour it will take on is harder to imagine. Some RS models have ridden well, some dreadfully, some have been engaging and some utterly inert, while some are a complex mix of all the aforementioned. All of which goes to make a test of the new RS4 a particularly intriguing one.

Promisingly, RS Audis of late have been getting more consistent, and getting better. More promisingly still, the best of the breed has, to date, been the previous-generation RS4 – a car that many of our testers would have chosen over a BMW M3 at the time.

And now it’s back, in its third generation, retaining a high-revving, naturally aspirated powertrain rather than following the rest of the industry’s inevitable progression towards blown motors. That was one of the high points of the most recent Audi RS4, so it sounds promising again. Let’s see if it delivers.
