As is the case with M parts, the exterior visual improvements come in the form of carbon elements fitted all around the car, like the radiator grille, air breathers or roof edge spoiler and fins.
At the interior, the most striking new elements are the M Performance Pro steering wheel that comes in Alcantara trim and with carbon fiber shift paddles, the LED door projectors and the velvet velour floor mats.
Production of the X4 M and X3 M began in April 2019, with both the two cars offered with a 3.0-liter in-line six cylinder engine. For both of new models, the engine develops 480 horsepower and a peak torque of 600 Nm of torque, providing the same 4.2 seconds acceleration time.
On top of the stock specs, both the cars can be fitted with the Competition package. This upgrade brings an extra boost in power and a reduction of acceleration time: 0.1 seconds shaved off the clock and an extra 30 hp of power added to the troop.
Both the X3 M and the X4 M are manufactured since April at BMW’s largest assembly facility, the one in Spartanburg, South Carolina.
BMW did not announce the availability or pricing for the M Performance parts meant for the two cars. Full details on this latest upgrade can be found in the document attached below.
