This Tuning Company Pushes The M6 To A Tremendous Top Speed

G-Power thinks the M6 needs more power.

It’s well-known that the bone stock BMW M6 convertible is no slouch. With 552 horsepower on tap right from the factory, there’s not much to complain about or even improve upon.That sort of power is fine for most, unless you’re talking to popular tuning house G-Power. It brought the twin-turbo 4.4-liter V8 engine up to 729 horsepower and 718 lb-ft of torque. Remapping the ECU did a lot of the work, but G-Power didn’t skimp on hardware improvements, either. A new titanium exhaust system was installed and the catalytic converters removed.

In addition to the lightweight titanium exhaust there's lightweight aluminum in the form of the 21-inch Hurricane RR wheels. All of the weight shaving and added power can propel you onto a top-down adrenaline rush of up to 186 mph. Okay, maybe stock looks a bit crappy compared to that.
