It’s the classic German duel—Audi v BMW—and Autocar has been kind enough to play out the latest fight for us. It’s the 331kW 4.2 litre RS5 up against the 309kW 4.0 litre M3. Will the extra power and quattro all-wheel drive in the Audi give it an edge over the benchmark rear-wheel drive M3?
There’s no fancy timing equipment, no drag strip and no race tracks to decide the winner here. It’s just a seat of the pants match up on a closed road. Just as it should be.
UPDATE: Auto Express has also had a crack at this comparison, and they did take the RS5 and M3 to the track. It’s not the world’s most in-depth review, but it’s still worth a look.
