Updated in 2021, the facelifted BMW X4 M F98 brought enhanced visual drama, an enlarged one-piece kidney grille, slimmer adaptive LED headlights and an overhauled centre console derived from the M8. Beneath the skin, the Competition variant adopted the forged lightweight crankshaft from the M3/M4 Competition, raising peak torque to a titanic 650 Nm. Maintaining this potent fastback projectile on British roads demands meticulous BMW X4 M maintenance, focusing on driveline health and thermal cooling systems.
The upgraded 510 hp S58 twin-turbo engine delivers its immense torque across a wider rev spectrum, coupled to the eight-speed M Steptronic transmission. Intelligent M xDrive and the active M rear differential distribute power with surgical precision, while adaptive M suspension tames the vehicle's rapid direction changes. High-performance compound brakes provide formidable stopping force, though they must handle substantial thermal loads on fast road runs.
