Hartge, in fact, borrowed the M5's 5.0-liter powerplant and seven-speed AMG gearbox for its new H50 V10. The engine has been massaged to deliver 550 horsepower, while torque remains at 384 pound-feet. Hartge says it has boosted the electronically governed top speed from 155 to 199 miles per hour. A new stainless steel exhaust system can be ordered with a pair of dual round or oval tailpipes.
The tuning house has added a reinforced rear axle and revised suspension pieces, and fitted 20-inch Continental performance tires — 245/30ZR-20s in front and 285/25ZR-20s in the rear.
Hartge, as always, has provided extensive modifications inside and out. The exterior gets a striking two-tone paint job, with additional air vents on the hood and fenders to help cool the big engine. A front lip spoiler and rear apron also have been added.
The cabin of the H50 V10 boasts carbon-fiber trim, a leather-wrapped steering wheel with carbon inserts, an illuminated leather/aluminum gearshift knob and leather/aluminum handbrake cover.
Hartge says it is also working on similar V10 conversions for the upcoming 3 Series coupe and wagon.
