While the world’s attention is focus on the recently launched M235i sports coupe, the German tuner Manhart Racing came with a very cool update for the old M135i. The tuner’s package is called MH1 400 and is a clear indication of the engine’s new output: 400 horsepower.

In order to obtain the extra power, the tuner remapped the 3-liter, straight six-cylinder engine’s ECU and installed a new, stainless steel exhaust system with two end pipes measuring 90 mm (3.54 inches). As a result the M135i is now delivering a total of 403 horsepower and 413 pound-feet of torque.

The only problem is that the speed limited was not removed, so the new MH1 400 still goes up to 155 mph.

In order to handle the extra power, the car was equipped with a new, KW Clubsport-coilover suspension system and new, 380 mm (14.96 inches) and 356 mm (14.01 inches) brake discs gripped by eight and four-piston calipers respectively

In order to indicate the extra power found under the hood, the tuner also made some updates to the exterior look. Changes include a new front spoiler and a new rear diffuser, both made in carbon fiber. New mirror caps also made in carbon fiber were also installed to make the car looking a little bit sportier. The tuner wrapped the car in a very cool aluminum brushed metal black foil combined with a yellow stripe on the side skirts.

The car rides on a new set of 19-inch concave wheels wrapped in Michelin SuperSport tires, sized 225/35 ZR19 up front and 225/30 ZR19 at the rear.
