German tuner Manhart Racing is working on yet another super BMW based on an ‘M’ model. The Manhart MH6 S turns the already bonkers M6 F12 into a full-on monster with a motorsport-inspired body kit and a heavily tuned powertrain.

The 4.4 liter biturbo V8 engine in the M6 is tuned by Manhart using ultra high performance parts, including a complete exhaust system including downpipes with sports catalysors and the company’s own end-silencer, and it makes a whopping 700 HP and maximum torque of 900 Newton meters.

The aerodynamic styling kit includes front spoiler and an engine hood, side skirts and a rear diffuser, as well as a new trunk with a CSL-style spoiler. All of these parts are of course made from carbon fiber.

A set of forged wheels and a coilover suspension system complete the package. Manhart says the kit is scheduled for releases in the late summer of 2013.
