It is 25 years since the world got its first truly sporting estate: the Audi RS2 Avant. Developed in conjunction with Porsche, the turbocharged five-cylinder, all-wheel-drive wagon blended five doors and 1,200 litres of boot with 311bhp and 0-62 in 5.4 seconds on its way to a 162mph top speed. Even today it sounds tasty.
No surprise then that it has proven to be an enduring formula, spawning four generations of fast wagons, since 1999 all badged RS4 to tie in with the rest of the A4 family. The RS4 has long being the top-seller in the whole RS line-up and is hailed by Audi Sport as among the best ideas it’s ever had. Now, there’s a new one.
