The front- and rear spoiler reduce the buoyant forces of the Hamann 6-series which has a effect on the car's handling and agility. This is also achieved with an additional pair of side skirts which significantly calms the air flow between both axles. The roof- and rear spoiler also ensure the necessary surface pressure on the asphalt.
Due to the large interest in different optical programmes, the designers developed another aerodynamics package called "Edition race". This turns the BMW in a sports car, as it consequently emphasises the broadening components. New front wings, 4-part wing broadenings in the back and enormous side skirts transform the BMW 6-series into an automobile which looks like a race car from the German Touring Car Masters or other touring car championships.
Basically, the sport limousine has a good motorisation, therefore Hamann put a special focus on the performance enhancement for the 630i, 650i and the diesel 635d. Adapting the motor management with up to 21 hp more and the powerful torque increase can be felt when accelerating. Moreover, Hamann customers can look forward to the Vmax abolition. This enables the 650i to boost the maximum speed from 250 to 270 km/h.
The Hamann sport exhaust system renders an earthy and impressive sound. The stainless steel muffler with its four round tail pipes can be optically perked up with metal catalysts, sport fan manifolds and a middle pipe set.

The recommended front wheel-tyre combination is 8,5Jx20 inches with tyres measuring 245/35ZR20 and 10,5Jx20 inches with 285/30ZR20 tyres in the back. One of the technical highlights of the offered tuning programme is the 21-inch model called HM EVO 'FORGED'. Manufactured in forge technology, it is extremely light and improves the handling, acceleration and braking characteristics by its reduced unsuspended masses. The front wheel-tyre combination is offered in 9,0Jx21 inches with tyres measuring 255/30ZR21 and 10,5Jx21 inches with tyres measuring 295/25ZR21 in the back. Prices starting at 7,620 euros.
