We’ve seen the upcoming G02 BMW X4 in spyshots before, but what we haven’t seen is a full-blooded M variant that will take on the Mercedes-AMG GLC 63. Well, now we have – the BMW X4 M has been spotted near the Spartanburg factory in South Carolina, confirming the existence of a high-performance variant.

Compared to the M Sport model that we’ve seen before, the hardcore model is differentiated by a larger centre air intake, as well as real instead of fake side inlets to feed air into the intercoolers. The wheels arches also look to have been blistered ever so slightly to accommodate a wider track, while the rear bumper features quad round tailpipes in typical M fashion.

Other notable items include cross-drilled brake discs – another hallmark of an M model – as well as subtle rear spoilers at the top of the windscreen and on the trailing edge of the tailgate. Missing, however, are M-specific door mirrors, although the production car should have them. Expect the interior to feature the usual M accoutrements, such as bespoke seats, gearlever and steering wheel.

Power should come from a new S58 3.0 litre twin-turbo straight-six that will also make its way to the next M3 and M4, with outputs set to exceed 450 hp. Given the F90 M5‘s move from a dual-clutch transmission to an eight-speed automatic transmission, expect the X4 M to use the same unit, sending drive to all four wheels.
