We absolutely love the new Audi RS4 here at BOTB. Okay, sure, the downgrade to a V6 from the V8 was a little disappointing at first, but that was before we drove it – the new 2.9-litre twin turbo V6 is a monster of an engine, and the RS4 handles incredibly well whilst looking like only an Audi RS Avant can – subtle yet menacing.

But what if you want…. more? Well, that would be ABT’s job – they take the RS4 and, using their considerable experience, make it the best RS4 you can buy – the RS4-S. As with any tuning job, you can expect the engine to get some work done, and you’d be correct – ABT’s ECU tune bumps power from 444bhp to 530bhp and torque jumps to 680Nm. That’s good enough for ABT to claim 0-62mph in 3.8 seconds, though that's certainly a conservative number. The top speed is 174mph which is adequate should you find yourself on the Autobahn.

Visually, ABT has done some great work, too – at the front; there’s carbon galore – carbon trimmed bumper intakes, a carbon lip spoiler sitting below it with the RS4-S logo on it, carbon front side blades, and there are some new vents behind the front wheels. At the rear, four 102mm carbon-tipped exhaust pipes release some much-needed noise and sit within a new, more aggressive carbon diffuser.

There are also a set of 21-inch GR alloy wheels which fill the arches perfectly thanks to the ABT lowered suspension - meaning it looks extra mean and low.

If that wasn’t enough, ABT has added some retrimming to the interior with their logos embroidered around the lovely Audi interior.

This may just be the best estate car we’ve ever had in the competition!
