Check out the Hamann Motorsport HM5/450 V12 based on the BMW 5 Series model. 

The Hamann Motorsport 6.1 engine is based on the BMW V12 engine. The cubic capacity is extended to 6.1 liters with the help of a special crankshaft and bigger pistons. In addition, the cylinder-heads are machined, sports camshafts and a special exhaust manifold are assembled. For the installation of the V12 into the engine compartment of the BMW 5 Series numerous parts such as the high performance exhaust system and assembly brackets had to be designed. The sporting demand is emphasized further with the six speed manual gearbox with sports clutch and a special rear axle differential with 40 per cent locking.

On the road the car reaches thoroughbred sports car level. The sprint from 0 - 100 km/h takes only 4.7 seconds, while the maximum speed is 311 km/h with a specially adapted transmission-ratio. To improve handling, Hamann Motorsport equips the HM5/450 V12 with a bigger brake system, sports suspension and 19 inch tires.

The three-piece Hamann Motorsport PG 2 rims are assembled in 9Jx19 front and 11Jx19 rear. For the tires, they chose 245/35 ZR 19 front and 275/30 ZR 19 on the rear axle. The tuning of the sports suspension can be individually adapted from very comfortable to extremely sporty according to the demands of the customer. To further reduce the side tilt of the car, there are stronger anti-roll bars.  Hamann Motorsport equips the sedan with a sporty-elegant aerodynamics-kit, which is available for all standard 5 Series cars.

The Hamann front spoiler bumper gives the 5 Series an even more striking face and minimizes lift at the front axle. For a further improvement of driving stability, the Hamann front fascia can be equipped with an additional Carbon lip.

From aside, the car looks lower and more stretched with the fitting of the Hamann side panels. To reach an excellent aerodynamic balance, Hamann Motorsport provides a roof spoiler, a rear wing in two different versions and a new, complete rear bumper. The Hamann rear apron has an integrated, Carbon-made diffusor and cutouts for the Hamann four-pipe high performance exhaust system. For the interior of the car, you can choose between the different BMW ex-works interiors and exclusive full leather trims from Hamann Motorsport. They also offer accessories like aluminum pedals and gear-shift-lever-knobs or wooden panels in noble walnut wood or bird-eye maple.

The Hamann Motorsport HM5/450 V12 is offered as a complete car or it is possible to convert a current BMW 5 Series model.
