More torque and quicker sprint times.
As with the regular X3 and X4, there are new headlights, new taillights, a larger kidney grille, model-specific new front bumper with larger intakes, a new rear bumper, and of course, an integrated roof spoiler. The X4 M doesn’t look much different when viewed from the rear-three-quarter angle compared to the outgoing model. 21-inch rims with mixed tyres (255/40 front; 265/40 rear) and M compound brake system come standard. As you might expect, the model-specific adaptive M suspension with electronically controlled dampers comes standard.
The cabin carries over all the updates made on the regular X3 and X4. However, unlike the regular models, the M models get the Live Cockpit Professional as standard with two 12.3-inch screens with model-specific graphics. A Head‑Up Display is optional. M sports seats with electrically adjustable headrests and illuminated M logo come standard.
Both models are powered by a 3.0-litre (2,993 cc) in-line 6-cylinder twin-turbo petrol engine that pumps out 375 kW (510 metric hp) at 6,250 rpm and 650 Nm (479 lb-ft) of torque between 2,750-5,500 rpm. While the power remains the same, the torque is up by 50 Nm (37 lb-ft). Both are claimed to sprint from 0-100 km/h (62 mph) in 3.8 seconds (quicker by 0.3 seconds). The top speed is limited to 250 km/h (155 mph), but can be increased to 285 km/h (177 mph) for extra money (M Driver’s Package).
