Having already drag-raced almost every generation of BMW M3, it should come as no surprise that Car Wow has since stuck a bunch of RS4s on one runway for an Audi-themed follow-up.
Oh, and an RS2 makes an appearance too – since it effectively spawned the RS4 dynasty, it has every right to be there, even if it’s out-gunned by its successors. Speaking of which, we have the original 2.7-litre twin-turbo V6 ‘B5’, the 4.2-litre N/A V8-powered ‘B7’, and the latest RS4, the B9, which has a 2.9-litre twin-turbo V6 you’ll also find in a bunch of Porsches.
We’re quite happy to drop a spoiler about the winner – it’s the most recent RS4, which is entirely expected. But it’s a lot closer than you’d expect between the B5 and B7 – press play and you’ll see what we mean.
