If you want a compact performance car that can put all of its competitors on notice, the Audi RS3 is an excellent option. However, if you already own an Audi S3 but are seeking RS3 levels of performance, then Manhart might be the tuner you want to get in contact with.

The German outfit has a wealth of experience tuning various Audi models and recently turned its attention to the S3. What it has created is dubbed the S 400 and, while it lacks the 2.5-liter turbocharged five-cylinder of the RS3, it promises to offer just as much performance.

Manhart has installed a carbon fiber air intake, a new intercooler, a stainless steel exhaust with valve control, and more importantly, remapped the ECU. The result is a cool 405 hp and 380 lb-ft (515 Nm) of torque, meaning the S 400 from Manhart actually has more power than the RS3 with its 401 hp and 367 lb-ft (500 Nm) of torque, despite using a small 2.0-liter turbocharged four-cylinder.

Various other alterations have been made. For example, new lowering springs have been installed to drop the ride height by about 30 mm. The Audi also now sits on a set of the tuner’s own 19×8.5 Concave One wheels with a satin black finish. Rounding out the standard upgrades are carbon fiber tips on the exhausts.

Manhart leaves both the interior of the S3, as well as its brakes, untouched but can upgrade both should customers wish to make their vehicle even more special.
