All we have to say about Lumma Design's gaudy color schemes inside and out for its new BMW M5 E60-based CLR 730 RS, is that we'll forgive any of you that mistake it for a bowling shoe maker's promotional vehicle... But seriously now, the CLR 730 RS features what the company claims to be the most powerful engine ever to be fitted on a road-legal BMW, courtesy of G-Power. The standard 5.0-liter V10 unit that makes 507HP and 520Nm has been upgraded with a pair of superchargers, a new sport exhaust system and various other modifications.
The result is a total output of 730HP and a peak torque of 700Nm (516 lb-ft) for a zero to 100 km/h (62mph) sprint time of 4.2 seconds. Lumma Design says that after 10 seconds the car reaches 200 km/h (124mph) and after 29.5 seconds, it breaks the 300km/h (187mph) barrier before it reaches its top speed of 367.4 km/h (226.8 mph).
The tuning firm has uprated the M5's brake system that now features 6-piston calipers with 405mm drilled disks up front and 4-piston calipers with 380mm drilled discs at the back. There's also an adjustable sport suspension that allows the car to be lowered by 45mm.
The wide bodykit that includes a new hood, trunk lid with an integrated spoiler, mirror caps, door handles, entrance strips and fenders, all of which are made out of carbon fiber, is said to be designed to improve the car's aerodynamics at high speeds.
The CLR 730 RS rides on a set of 21-inch lightweight forged alloy wheels shod in tires size 255/30 up front and 295/25 at the back.
Inside, Lumma Design upgraded - downgraded (take your pick) the M5's cabin with two-tone leather seats and door panels with quilted patterns and more carbon fiber accents than a NASA parts cupboard. The German company did not disclose pricing on the M5 CLR 730 RS.
