The car
The G82 M4 went on sale in the US in March 2021, and it is a larger car than the M4 (F82) it replaced: 4.6 inches longer, 0.7 inches wider and 0.4 inches taller, on a wheelbase stretched by 1.8 inches to 112.5. That wheelbase matches the G80 M3 sedan, but the coupe stands 54.8 inches tall and seats four.
Its S58 engine is a 3.0-liter inline-six with two mono-scroll turbochargers, a closed-deck block and a forged crankshaft, redlined at 7,200 rpm. In the US the base coupe pairs it with a six-speed manual and rear-wheel drive; BMW quotes 0–60 mph in 4.1 seconds, a curb weight of 3,830 pounds, and a top speed of 155 mph, or 180 mph with the M Driver’s Package. The roof is carbon fiber.
The automatic M4 Competition, the all-wheel-drive Competition xDrive and the lightweight CSL each have their own page.
Stage 1 is calibrated for the car as it left the factory and takes it from 473 hp and 406 lb-ft to 750 hp and 730 lb-ft on pump-grade fuel. Stage 2 is calibrated for supporting bolt-on modifications and high-octane fuel, for 785 hp and 750 lb-ft. The gearbox has its own controller and torque limits, so the optional TCU tune raises them to match, with sharper shifts and stronger clutch clamping.

Our online catalog lists Stage 1 and Stage 2 tunes for 2021–2024 BMW M4 (G82) models. Choose your year at the top of the page; the figures and prices are the same for every year.
The G82, listed from 2021, has a large, deep frameless kidney grille, while the F82 of 2015 to 2020 has a smaller, conventional pair. The G82 uses the S58 engine, has a manual-only base model in the US, and is longer, wider and taller. The earlier coupe has its own page, M4 (F82).
The base coupe with the six-speed manual and rear-wheel drive. The M4 Competition (G82) has the eight-speed automatic and a higher rating, the M4 Competition xDrive (G82) adds all-wheel drive, and the M4 CSL (G82) is the two-seat lightweight; each is on its own page.
Stage 1 is calibrated for the car as it left the factory and runs on pump-grade fuel. Stage 2 pairs the calibration with supporting bolt-on modifications such as downpipes and runs on high-octane fuel. On a 2024 car, Stage 1 takes it from 473 hp to 750 hp. Stage 2 takes it to 785 hp.
A TCU tune is available as an add-on ($1,999). It raises the transmission’s torque limits and sharpens the shifts so the gearbox can handle the extra power. Ship your TCU in the same box as your ECU.
