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.
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.

BMW M GmbH expanded its high-performance model line-up to include models in the mid-size Sports Activity Vehicle (SAV) and Sports Activity Coupe (SAC) segments for the first time. The BMW X3 M and BMW X4 M set the benchmark for dynamic excellence, agility and precision in their respective classes.Also new is the launch alongside the BMW X3 M and BMW X4 M of their Competition siblings. The BMW X3 M Competition and BMW X4 M Competition will capture customers' imagination with their extra power and exclusive appointments.The addition to the BMW M GmbH line-up of its first high-performance models in the mid-size Sports Activity Vehicle (SAV) and Sports Activity Coupe (SAC) segments also heralds the arrival of a newly developed sixcylinder in-line engine in two variants. The engine stands out with its familiar M high-revving character, the latest M TwinPower Turbo technology update, plus track-tested cooling and oil supply systems. It develops 353 kW/480 hp in the BMW X3 M and BMW X4 M, and an even mightier 375 kW/510 hp in the BMW X3 M Competition and BMW X4 M Competition.The standout performance characteristics of the 3.0-litre units are encapsulated by the linear power development that is such an M speciality, plus a hunger for revs quelled only by the engine's limiter. And all to the tune of an arresting soundtrack. Like the maximum output figure, peak torque of 600 Nm (442 lb-ft) also represents a new high point for a six-cylinder in-line petrol engine from BMW. The ongoing development of M TwinPower Turbo technology, coupled with the inclusion of two gasoline particulate filters and four catalytic converters, also ensures the high-performance engines can claim remarkable efficiency and exceptionally low emissions.
