ABT has given the Audi S5 Avant a nice little power bump and made it faster

Just don't ask us about the name of the thing

Published: 29 May 2025

Venerable Audi tunificator ABT has given the new S5 Avant an upgrade package. We would say it's pushed it closer to a potential RS5 Avant, but since our heads are still spinning from Ingolstadt's naming convention changes, we have no idea what anything means anymore. So let's just call it 'quick'.

And 'powerful'. ABT has taken the 3.0-litre V6 and opened it up a bit, bumping the outputs from 362bhp/369lb ft to 434bhp/443lb ft. The 155mph top speed remains unchanged, but the extra 72bhp should help cut the original 4.5s 0-62mph sprint down a bit.

Visually, it looks like yer typical Black Edition-grade car. There’s 25mm lowering springs to drop it right down, and a full bodykit that includes a more aggressive front lip, inlet cover and rear wing.

Bigger 102mm stainless steel quad exhausts sit at the back, while 20in five-spoke ‘Prime’ alloys hide inside those arches. Why they’ve been named after KSI’s energy drink, we don’t know. Still, this thing looks good. Hot estates normally do.

By comparison the interior’s changes are much subtler: integrated entrance lights into the door sills, ABT-branded floor mats, a new start-stop switch and… that’s about it. Seems like some aftermarket tuners do still remember how to keep things low-key.

You’ll be forking out €14,900 (about £12.5k) for the package, which seems decent for the power hike and leaner suit you’re getting in return. Before all that though you’ll need to first get an S5 Avant, which used to be an S4 Avant but will remain an S5 Avant (we think), and the going rate for one of those nowadays is £72,450… at least.
