I must admit that the BMW 1 Series was never my favorite, not even the M version, for all the great things it can do.

But there are some tuning projects out there that make even me desire a vehicle like that. And for all the improvements Tuningwerk applied on the M135i, this particular version doesn’t do it for me.

In the standard form, the BMW M135i is able to produce 355 Hp. After installing a new turbo, the in line six cyclinder engine now produces 445 Hp. To keep the power steady, especially on the bends, Tuningwerk also installed a limited slip differential.

Drive stability was also improved by the addition of triple adjustable KW Clubsport suspension system. The brakes were updated to BMW Performance, with some personal touches from Tuningwerk. For those that went with manual transmission, the aftermarket specialist also offers two choices of flywheels. Depending on your needs, you can shave either 2 kg or 4.5 kg off the part.

As for the interior, Tuningwerk didn’t really bother too much, with only new seats from Recaro installed and a rollcage.
