BMW has released a handful of images showing its new X3 M and X4 M prototypes in action, as it finally officially confirms the expansion of its high-performance range.

Set to slot in below the X5 M and X6 M, the two new M-badged crossovers will take on the V8-powered Mercedes-AMG GLC63 and GLC63 Coupé.

The camouflaged pre-series vehicles boast large air intakes up front plus what the Bavarian automaker describes as “specific M features for optimised aerodynamics”. An exhaust system with four tailpipes integrated into the rear apron is also included.

So, what’s under the bonnet? Well, BMW says the new X3 M and X4 M will each be powered by a “newly developed” straight six-cylinder engine with “M TwinPower Turbo technology and high-revving characteristics”.

Both will also feature the brand’s so-called “M xDrive” all-wheel-drive system, which BMW says will provide “maximum traction and loss-free distribution of drive torque for achieving extremely dynamic handling characteristics”, as well as an active M rear axle differential.

“With their M-specific performance characteristics, the BMW X3 M and the BMW X4 M will set benchmarks in terms of dynamics in their respective vehicle segment,” said Frank van Meel, president of BMW M.
