This dynamic-looking roadster looks like your ordinary BMW M6 Convertible (F12). Wrapped in a brown metallic exterior color finish, this BMW M6 Convertible really looks like the average M6 Convertible. But wait until it gets on the road, as this brown BMW M6 Convertible -- as tuned by G-Power -- is a sleeper that could go toe to toe with a Porsche 911 Turbo S Cabriolet in terms of top speed.
Don’t be mistaken; we’re not describing the BMW M6 Convertible as slow. After all, the BMW M6 Convertible is the performance version of the drop-top 6 Series. The most powerful BMW 6 Series Convertible is served by a 4.4-liter BMW TwinPower Turbo V-8 engine that is able to deliver at most 443 hp (330 kW or 450 PS) of output available between 5,500 rpm and 6,000 rpm, as well as up to 650 Nm of torque available between 2,000 rpm and 4,500 rpm. This is enough to send the most powerful BMW 6 Series Convertible accelerating from zero to 100 km/h in just 4.5 seconds and reaching a top speed of 250 km/h (155.4 mph).
The less dynamic version of the BMW 6 Series Convertible – powered by a 3.0-liter BMW TwinPower Turbo inline 6-cylinder – features 315 hp (235 kW) of max output and 450 Nm of peak torque. This level of power is already aplenty, as it is enough to make the BMW 6 Series Convertible sprint from zero to 100 km/h (62 mph) in just 5.4 seconds and reach a max speed of 250 km/h (155.4 mph).
Here comes the BMW M6 Convertible – made for those who wanted a performer amidst the style and elegance of the BMW 6 Series. The performer nature of this version of the 6 Series is not just because of its looks, but also because of what is lurking underneath its long and curvy hood. The core of the BMW M6 Convertible is a 4.4-liter BMW M TwinPower Turbo V-8 that is well tuned to provide 552 hp (412 kW or 560 PS) available between 6,000 rpm and 7,000 rpm as well as 680 Nm of peak torque available between 1,500 rpm and 5,750 rpm. This amount of power could send the BMW M6 dashing from standstill to 100 km/h in 4.3 seconds and reaching a top speed of 250 km/h (144.4 mph). When the Competition is availed, the power levels of the M6 surge by 40 PS and 20 Nm more.
But for those who think that the expected figures for the BMW M6 aren’t enough, G-Power has the answer for you. The horsepower-crazy people at G-Power have upgraded the 4.4-liter BMW M TwinPower Turbo V-8 engine of the M6 to produce 789 hp (588 kW or 800 PS) of max output and 1,050 Nm (774 lb.-ft.) of peak torque. Since the electronic top speed limiter has been removed, the G-Power M6 could go as fast 330 km/h (205 mph) – with the same max velocity of the Porsche 911 Turbo S Cabriolet.
This feat is achieved by making several tweaks on the hardware and software of the 4.4-liter BMW M TwinPower Turbo V-8. For instance, the two turbochargers have been upgraded with bigger and more efficient turbines while larger downpipes and a titanium exhaust system were also installed. Likewise, G-Power reprogrammed the engine’s ECU map while installing a height-adjustable coilover suspension.
Lightweight 21-inch custom wheels wrapped in performance tires were also thrown in. All of these upgrades would cost a discerning client around €29,632 (about $31,220), although each tweak could be availed separately.
