The car
From launch, BMW offered both of its compact M SUVs in two outputs, and the Competition is the stronger one. Its S58 inline-six makes more power than the standard engine, and BMW’s figures for the 2020 models put it at 4.0 seconds to 60 mph, with the M Driver’s Package raising the limited top speed from 155 to 177 mph.
The extras are visible as well: 21-inch Jet Black wheels on 255/40 front and 265/40 rear tires, an M Sport exhaust with black chrome tailpipes, high-gloss black trim around the kidney grille and M Sport seats in extended Merino leather. Mechanically it otherwise matches the standard X3 M and X4 M, with the eight-speed M Steptronic, rear-biased M xDrive, model-specific suspension bushings and a body reinforced at the suspension mounting points. The X3 M Competition is the upright SUV and the X4 M Competition the version with the coupe roofline.
On a 2024 car, Stage 1 is calibrated for the car as it left the factory and takes it from 503 hp and 443 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.

FAQ

Our online catalog lists Stage 1 and Stage 2 tunes for 2019–2024 BMW X3 M / X4 M Competition (F97 / F98) models. Choose your year at the top of the page; figures and prices for each year are shown in the table above.
More power from the same S58 engine, 21-inch wheels instead of 20-inch, a sport exhaust and gloss-black exterior trim. The gearbox, M xDrive and chassis hardware are shared, and the standard models are listed on our X3 M / X4 M (F97 / F98) page.
It is the same S58 family. The X3 M and X4 M were the first BMWs to use it, in 2019, before the G80 M3 and G82 M4 arrived for 2021, and the SUVs pair it with M xDrive as standard. The M3 Competition (G80) has 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 503 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.
