Shown in pre-production form as indicated by the still present layers of disguise, both models receive a redesigned front bumper with wider air vents, uprated brakes as indicated by the blue calipers, a mesh honeycomb grille, wider door sills, specifically designed mirrors to aid aerodynamics, a new rear bumper and quad exhaust outlets.
In addition to reaming mum on the models’ interior, BMW has also declined to reveal technical details, merely stating that both will come powered by a “newly developed straight six-cylinder engine with M TwinPower Turbo technology and high-revving characteristics”. Based on previous reports however, the engine in question will likely be a development of the current 3.0-litre unit powering the M40i models, which will produce the same 331kW as the M3/M4 Competition Pack (CP).
While these model are touted as a rival to the Mercedes-AMG GLC 63 and coupe as well as the Audi SQ5, earlier sightings have alleged BMW to be working on a CP version of the X3, which will later include the X4, that will produce as much as 349kW and go head-to-head with the GLC 63 S and RS Q5. Regardless of the model and power outputs, an eight-speed Steptronic gearbox and xDrive all-wheel drive will be standard.
Aside from their exterior and interior updates, as well as power uptakes, both the X3 and X4 M will benefit from revisions underneath in the form of the Active M rear differential, M sport adjustable dampers and suspension as well as the same M1 and M2 buttons as the M5.
Although no confirmed date for either model’s launch was made with M division boss Frank van Meel stating that both “will set benchmarks in terms of dynamics in their respective vehicle segment”, the minimal levels of camouflage suggests that a world debut at the Paris Motor Show in October could be on the cards.
