Has the same top speed as a Porsche 911 Turbo S Cabriolet.

With 600 horsepower and 516 pound-feet of torque, you’d think the BMW M6 Convertible fitted with the Competition Package has plenty of Bavarian muscle in stock form. The tuners at G-Power have an entirely different opinion as they have fiddled with the 4.4-litre V8 engine to squeeze a monstrous 800 hp and an insane amount of torque: 774 lb-ft.

These impressive numbers have turned the M6 into one of the fastest convertibles ever made, capable of running the sprint to 200 kilometres per hour (124 miles per hour) in 9.8 seconds before maxing out at 330 km/h (205 mph) once the tuners remove the electronic top speed limiter.

It had to undergo a lot of changes to achieve these output and performance numbers, with G-Power’s focus being on the eight-cylinder BMW engine now featuring both hardware and software revisions. Most of the power bump was achieved by fiddling with the two turbochargers thoroughly upgraded in-house with bigger and more efficient turbines.

Larger downpipes were necessary to cope with the extra power provided by the V8, while a titanium exhaust system was also installed for further boost. As you can imagine, the engine’s ECU also had to be reprogrammed to match the upgraded internals.

G-Power didn’t stop there as it also gave the M6 Convertible a height-adjustable coilover suspension and lighter 21-inch custom wheels matched with performance tires.

Needless to say, these upgrades don’t come cheap. The special engine mapping costs €4,550 (approx. $6,400 CAD), while the electronic top speed limiter removal is €668 (approx. $1,000 CAD). If you want the upgraded turbochargers, that’ll be an extra €3,850 (approx. $5,400 CAD). The aforementioned downpipes with sports catalysts cost €3,860 (approx. $5,500 CAD) and the titanium exhaust is a pricey €6,679 (approx. $9,500 CAD). Rounding off the upgrades are the forged wheels with matching tires for €7,649 (approx. $11,000 CAD) and the coilover suspension for €2,376 (approx. $3,400 CAD). Do the math and you’ll end up paying €29,632 (approx. $42,000 CAD).
