The more aggressive styling also makes it look more like an M4 GTS.
If the BMW M6 Coupe is too tame for you, tuning firm G-Power has a solution. In stock form, the M6 Coupe's 4.4-liter twin-turbocharged V8 produces 552 hp and 501 lb-ft of torque on tap, but thanks to G-Power's modifications it now has 789 hp and 774 lb-ft of torque, putting it firmly in supercar territory.
To achieve this, the tuner reworked the turbochargers and added numerous performance parts under the hood. As a result, the modified M6 can hit a top speed of 205 mph. G-Power hasn't revealed the 0-62 mph sprint time, but considering the stock M6 equipped with the Competition Package takes 3.9 seconds there's a good chance that number is now closer to the three-second mark.
Unsurprisingly, turning the BMW M6 into a 800-hp beast isn't cheap. In Germany, G-Power's Performance Software V4 costs €3,519.43 ($4,009), the modified turbochargers add another €4,581.50 ($5,219), the downpipes with sport catalyst are priced at €4,593.40 ($5,232) and the exhaust titanium system will set you back another €6,501.47 ($7,406) – and that's without the €1,446.59 ($1,649) carbon tailpipes. Opting for the increased V-max will set you back another €516.70 ($589). Oh, and these prices don't include the cost of installation.
To complement the car's performance boost, G-Power modified the M6 to look more like an M4 GTS thanks to a carbon fiber body kit that adds a new front spoiler, side skirts, diffuser, rear wing and a new hood. These new parts have been aerodynamically engineered and give the car "significantly" more downforce on both axles. Rounding off the changes is an adjustable an suspension and a new set of 21-inch wheels wrapped in 255/30 and 295/25 tires. Too bad BMW stopped producing the 6 Series Coupe in the US last year.
