Here’s a video of the 550bhp H50 V10 monster from Hartge. It’s in German, but you won’t be taking much notice of the guys voice…
The H50 V10 is based on the BMW 3 series saloon (E90). Fitted with a modified M5 V10 engine, a 7-speed SMG gear box and the HARTGE modification to raise maximum speed from the electronically limited 155 mph to 198 mph, the H50 V10 puts all its power – 550 bhp and torque of 520 Nm (384 lb-ft) – onto the tarmac via a reinforced rear axle and a special suspension setup that is adjustable in terms of both rebound and compression.
Also new and made especially for the HARTGE H50 V10, is the stainless steel exhaust system, which turns the V10 sound into an acoustic delight. Customers can choose between two dual round (or oval) tail pipes. The wheel / tyre combination consists of 9 x 20 offset 40 at the front and 10 x 20 offset 40 at the back fitted with 245/30 ZR 20 and 285/25 ZR 20 Continental tyres respectively.
