Manhart Performance has released additional details and pictures of their upgrade program tailored for the BMW M135i.

The kit was originally introduced a few months ago at the Essen Motor Show with a power upgrade for the 3.0-liter six-cylinder turbocharged engine bumping output from 320 HP (235 kW) and 332 lb-ft (450 Nm) to 405 HP (298 kW) and 413 lb-ft (560 Nm). The additional power is obtained by installing an additional control unit and a different exhaust system.

More power implies the necessity of additional stopping force which this BMW M135i has received via the tuner’s 380x32mm discs with 8-piston fixed calipers at the front and 4-piston calipers at the back. The vehicle now rides on a fresh new set of 19-inch alloy wheels wrapped around in Michelin Super Sport tires while for added grip there’s a KW Clubsport chassis and a Quaife locking differential.

For the interior Manhart has prepared a combination of leather and Alcantara upholstery with yellow contrast seams, carbon/aramid decorative stripes and BMW Performance seats. On the outside it's wearing a matte foil and has received carbon fiber mirror caps, splitter and diffuser.

Manhart mentions all these upgrades are available for both the rear-wheel drive and xDrive versions of the BMW M135i.
