G-Power packs 800 hp into the BMW M6 Convertible image

The BMW M6 Convertible with the Competition Package is already a pretty hardcore machine when getting out the factory gates – but the aftermarket specialists at G-Power decided to instill even more power.

In standard speck, the M6 Convertible with the Competition Package packs 600 horsepower (447 kilowatts) and 516 pound-feet (700 Newton-meters), but it seems that’s not enough for some. So the tuner decided to massage the 4.4-liter V8 engine for a huge 800 hp (588 kW) and a monstrous amount of torque: 774 lb-ft (1,050 Nm). This means the M6 drop top is one of the quickest convertibles in the world, capable of jumping to 124 mph (200 kph) in 9.8 seconds before topping out at 205 mph (330 kph) following the removal of the electronic top speed limiter. The engine had both hardware and software upgrades to reach the desired figures.

For example, the two turbochargers got in-house larger and more efficient turbines. Bigger downpipes as well as a titanium exhaust system were also part of the pack. There’s a matching ECU reprogramming, but also a height-adjustable coilover suspension and lighter 21-inch alloy wheels with performance tires. The first part engine upgrade alone costs €4,550, with the electronic top speed limiter removal another €668. Get the new turbochargers, that’ll be an extra €3,850. The aforementioned downpipes with sports catalysts cost €3,860 and the titanium exhaust is a drooling €6,679. The wheels and tires are €7,649 and the coilover suspension is another €2,376.
