For the 2022 model year, the BMW M8 range received new colors and infotainment upgrades. There weren’t any changes under the hood though, where the 4.4-liter twin-turbocharged engine continued to offer the same 617 horsepower and 553 pound-feet (750 Newton-meters) of torque as before. There have always been interesting options for modifying the M8 family and there’s a new impressive package coming from G-Power for the M8 Gran Coupe.
Starting with the most important thing – the power upgrade. The V8 S63 mill has received new forged pistons and connecting rods, two new air coolers, optimized turbochargers, and a new engine control unit. Thanks to these hardware tweaks, the output of the 4.4-liter unit jumps to 900 hp and 774 lb-ft (1,050 Nm) of torque. The power boost comes with a nice exhaust sound enhancement courtesy of G-Power in-house developed exhaust system with carbon tailpipes with lower exhaust back pressure.
