German tuner offers a substantial power boost on the 650i Cabrio along with 19- or 20-inch wheels.

German tuner Kelleners Sport has a package for the BMW 6-Series Cabriolet that includes a power boost on the 650i model.

The tuner sees no need for an aero kit on the 6-Series Cabrio but starts things off with an engine tuning on the 650i that boosts power to an output of 490 PS (360 kW), up from the series 407 PS (300 kW). Torque also rises to a maximum 720 Nm (531 lb-ft), from the standard 600 Nm (442 lb-ft).

For the new wheels, Kelleners offers a variety of 19- and 20-inch wheel/tire combinations. Rims come in either Hamburg or Berlin design with tires in dimensions ranging from 245 to 285.

On the inside, the tuner adds aluminum foot supports, pedal pads and new velour floor mats along with options for a cabin finish in leather upholstery and wood trims.
