Kelleners Sport’s tuning package for the new BMW 6 Series Cabrio increases the power output of the 650i to 490 hp.
Kelleners realized the looks of the new 6er is handsome enough so they didn’t bother with body kits and stuff and just offer new wheels, 19 or 20-inch in size. The black-finished multi-spoke wheels on this car look particularly good.
Same applies for the interior. They just added some aluminum pedals and pads and some fancy velour mats, but you can also order new leather upholstery or wooden trims.
As for the engine, as mentioned the the V8 engine is boosted from the standard 407 to 490 PS and the torque from 600 to 720 Nm. That’s the remarkable increase in power which should enhance the performance dramatically. That said, the Vmax is limited to 250 km/h.
