To achieve its power upgrades, engineers have recalibrated the standard ECU, which leads to a 10hp boost for the 320i and an additional 10Nm of torque. The most powerful model in the range, the 335i, gets a power boost of 37hp that lifts the cabrio's top speed to 279km/h. Hamann also offers customers a sports air filter for the engine to help provide better power delivery throughout the rev range.

For the 330d, owners can expect a final output of 272hp and 600Nm of torque from as low as 2,000rpm, which enables a top speed of 256km/h. The car’s body has been enhanced with new bumpers, side skirts and four-pipe mufflers plus carbon-Kevlar mirror caps to add that performance touch.

Other accessories include three different sized forged wheels, upgraded brakes, and a lowered suspension kit.
