Packing all of 625 PS (616 hp / 460 kW) and 750 Nm (553 lb-ft) of torque, the BMW M8 Coupe is a true Bavarian flagship. At €175,000+, it is not exactly affordable, either. The tuning team of G-Power recommends buying an M850i xDrive instead and putting that €43k+ you saved into tuning.
With an M850i, your starting point is much lower at 530 PS (523 hp / 390 kW). However, opting for an engine upgrade can yield up to 670 PS (661 hp / 493 kW) along with 900 Nm (664 lb-ft) of torque. For an extra $500, you can remove the speed limiter and let the 8-Series exceed 300 km/h (186 mph) in a straight line without breaking a sweat.
There are also some exterior mods to consider. The list starts with a carbon-fiber hood with air intakes, an engine bay lid made from the same material, and a rear spoiler. Standard wheels can be replaced with lightweight Hurricane RR or RS series rims sized 20 or 21 inches in diameter. There is very little available for the interior, though – mainly tuner’s badges and plaques.
You may contact G-Power directly for a price quotation, but we are told that boosting an M850i Coupe produced in June 2020 to its max potential would set you back €28 per metric horsepower. To put things into perspective, if you would rather buy the “real” M8 for its raw performance, you would be adding €455 per horsepower over the M850i. So, tuning is clearly the more affordable option of the two by far.
