German tuner dials output up on the 2012 BMW 650i Cabriolet by more than 100 HP.

German tuner Hamann has previewed its program for the BMW 650i Cabriolet.

For the power boosting, Hamann plans on dialing output up to 510 PS (375 kW / 503 hp) from the series' 407 PS (300 kW). Hamann will also be adding its own sport exhaust system with quad stainless-steel pipes.

The body kit includes new LED daytime running lights, front spoiler, rear spoiler and rear apron, as well as side skirts.

Suspension tuning involves a lowering by 30 mm and various rim/tire combinations are on offer on the 6-Series Cabrio in sizes 21- and 22-inches.
