Kelleners Sport Teases its BMW 6 Series Gran Coupe

Tuning

The big BMW 6 Series Gran Coupe is the subject of performance tuner Kelleners Sport's latest upgrade program.

German aftermarket tuning firm Kelleners Sport has just revealed these new photos of its upgraded BMW 6 Series Gran Coupe. For the moment, no official details are available in regards to engine and performance upgrades. But these newly released photos show the big four-door coupe with some serious exterior mods that include a new front bumper with honeycomb inserts, a ventilated hood, sleeker side skirts, and new alloy wheels.

Out back features a new spoiler, sports exhaust system, as well as a new rear bumper that’s integrated into the diffuser. Despite not knowing its official output numbers, WorldCarFans speculates that based on Kelleners’ past work, a remapped ECU is a very likely possibility. Although this tuning program isn’t for the beastly M6 Gran Coupe, we’re assuming the focus here is on the 650i that comes with the 4.4-liter twin turbo V8. In stock form, that engine spits out 440 horsepower and 479 lb-ft of torque.
