The appearance and standard equipment of the BMW X4 M40i and BMW X4 M40d are based on the corresponding X3 models and, like these, have typical BMW M insignia such as the specific BMW M kidney grille with chrome frame, double kidney grille slats in black high-gloss and the M logo as well as the aerodynamically optimized M exterior mirrors in high-gloss black. The rear apron with the anvil-shaped insert is fitted with air curtain panels in high-gloss black. Similar to the BMW X3 M40i and BMW X3 M40d, the free-form tailpipe trims are in black chrome with the two "teeth" and the tires.

The in-line 6-cylinder engine in the BMW X3 M Competition and BMW X4 M Competition now features the forged lightweight crankshaft of the BMW M3 and M4 models. Its extremely torsion-resistant design enables transmission of the particularly high torque, while its low weight and reduced rotating masses also benefit the engine’s revving power. The in-line 6-cylinder engine’s racetrack-proven cooling system is designed to enable an exceptionally high level of output and includes two laterally positioned radiators in addition to the central one. There is also an additional engine oil cooler and a separate transmission oil cooler. BMW M GmbH motor racing expertise is also evident in the design of the oil supply system, which is geared towards dynamic racetrack operation. The engine’s weight-optimised oil pan has two separate chambers and an integrated suction channel. An additional suction stage enables the map-controlled oil pump to deliver lubricant from the smaller oil sump, which serves as a volume buffer. In this way, a reliable oil supply is guaranteed at all times, even during extreme longitudinal and lateral acceleration.
