This is the latest tuning package for the Audi RS6, a range of tweaks by German firm Reifen Koch (no sniggering at the back there) that brings the already ballsy Audi to 690bhp and 583lb ft of torque.
We're generally a little uncomfortable with tuned cars here on PistonHeads - taking a spanner to an ECU, fitting alloys of dubious taste and a custom exhaust are unlikely to be changes that improve upon a car whose original R&D budget probably stretched into the billions.
But the Reifen Koch RS6 is a little different. Yes, there are laughably huge 22-inch alloys wrapped in 265/30 rubber and yes, a custom exhaust is present, but - crucially - the ECU upgrades that liberate such prodigious power (118bhp and 104lb ft more than in the standard RS6) allow a top-speed of 205mph. And that we like.
It's certainly a very fast way to transport a Labrador, should you choose to send an RS6 Avant for the treatment...
