Based on the 3 Series Compact, the Hamann Motorsport 3.2 liter/350 hp may be the fastest compact car in the world.

The source of power is the engine from the M3. The M3 engine power has been increased to 350 hp / 257.6 kW with some modifications. The 3201 ccm engine is upgraded with a special exhaust manifold and new mappings for the electronic-control-units for Motronic and VANOS. Inside the engine compartment, the new air-collector is made from Carbon/Kevlar. This new piece contributes to the higher power output of the engine due to its Formula 1 style airbox. There is a specially tuned high performance exhaust system and many special parts to make the engine fit into the front section of the compact.

Power transmission is done by a six-speed manual gearbox taken from the new M3 and by a stronger rear axle differential with 40 per cent locking rate. So the Hamann Motorsport HM 3.2/350 catapults from 0 - 100 km/h in 4.8 seconds with a top speed of 289 km/h. 

This kind of performance calls for far-reaching modifications on the aerodynamics which are made with wide body conversion. The new front skirt with additional spoiler-lip reduces the lift on the front axle.

Downforce on the rear axle is achieved with the big, adjustable rear wing with extendable Gurney-flap and the new rear-skirt with diffusor. The bolt-on, sportily swinging fender flarings front and rear make the Hamann Motorsport runabout 184 centimeters wide and give space to extremely wide wheels. 

To achieve maximum possible traction, the compact car is equipped with three-piece Hamann Motorsport Pegasus light alloy rims of the dimensions 12Jx18 and Yokohama tires in the format 285/35 ZR 18 on the rear axle. For the transfer of the steering and braking forces onto the front suspension there are nine inch wide wheels with 245/40 ZR 18 tires. Between the openings there are integrated sportily styled side-skirts with ventilation-intakes for the rear brakes. In addition, the Hamann Motorsport HM 3.2/350 is equipped with a Carbon-hood, sports-side-mirrors and an underbody cover.

Hamann Motorsport furnishes the two-door car with a height-adjustable sports suspension, which lowers the chassis by 40 millimeters. The shock absorber tuning can be chosen between sportily comfortably and race-like hard. The suspension package additionally includes adjustable torsion bars, front strut brace and a high performance brake system with 330 mm large, ventilated discs and multi-pistons calipers. For the interior there are optionally available luxurious full leather appointments or a racing-light- weight cockpit. The Hamann Motorsport HM 3.2/350 is hand-built on special request.
