This 730 horsepower M5 gets from 0-100 km/h in 4.2 seconds, on its way to a top speed of 367.4 km/h.

A German tuning/design company has just released a new performance tuning package for the BMW M5 E60.  Winterlingen-based Lumma Design has been working with the engineers at G-Power on an upgrade kit to the M-badged version of the 5-series.

The result is a car that uses all 730 horsepower of a bi-compressor V10 to reach a maximum speed of over 367 km/h (228 mph).  The 700 Nm of torque helps the car go 0-100 km/h time in 4.2 seconds, reaching 200 km/h in just ten seconds.  300 km/h is achieved in 29.5 seconds.

The companies claim this is the "most powerful engine" ever seen on a "road-legal BMW."  It is certainly a huge development over Lumma's CLR 500 RS released in 2007.  That car saw a "paltry" 560 horsepower.

Certainly, these figures require non-stock brakes.  Lumma Design's own six-piston front, four-piston rear caliper brakes are used along with drilled 405mm discs.  Ultralight, three-piece forged 10x21 and 12Jx21 wheels at the nose and tail look great on the 45mm lowered car.

The design package includes carbon fiber boot and bonnet, and the material is also used for the door handles, entrance sills, fenders, and mirror caps.  Designers also replaced the exhaust system.  Inside, carbon fiber, leather, and suede is used gratuitously.  Hopefully, the color scheme chosen inside is customizable, as something more subtle than the contrasting red, white, dark grey would probably feel more appropriate.
