BMW M8 Gran Coupe owners looking for a power upgrade to mix it with supercars in a straight line can now turn to G-Power, who has released a special tuning upgrade.
With the Stage 3 upgrade, the 4.4-liter twin-turbocharged V8’s output and torque rise from the standard 616 HP (625 PS / 460 kW) and 553 lb-ft (750 Nm) in the M8 Competition to a jaw-dropping 808 HP (820 PS / 603 kW) and 738 lb-ft (1,000 Nm).
The tuner’s online configurator tool reveals a €4,595 (equal to $5,585) price for the GP-820 performance software, €5,950 ($7,232) for the turbocharger upgrade, €5,360 ($6,515) for the sport downpipes and €5,950 ($7,232) for the GP-Deeptone exhaust system with four carbon fiber tailpipes. Removing the V-max limiter, which allows the car to hit 205 mph (330 km/h), up from the standard top speed of 155 mph (250 km/h) or 190 mph (305 km/h) with the M Driver’s Pack, costs another €495 ($602).
Stage 2 unleashes 759 HP (770 PS / 566 kW) and 686 lb-ft (930 Nm) and Stage 1 brings 710 HP (720 PS / 530 kW) and 627 lb-ft (850 Nm) to the party. There’s no saying how quick the tuned M8 Gran Coupe is to 62 mph (100 km/h) with either of these, but the stock M8 Competition needs only 3.2 seconds.
Other upgrades for the M8 Gran Coupe include a sound optimization software for the exhaust system (€245 / $298), custom carbon fiber bonnet (€5,950 / $7,232), dynamic carbon wing (€3,332 / $4,050), 21-inch RR or RS forged wheels (price upon request), engine cover (€1,785 / $2,170) and sports steering wheel (price upon request).
