The new G06 BMW X6 has yet to make an official debut, but it looks like the Bavarian giant is already working on the full-blown X6 M. This fully-camouflaged prototype was spotted undergoing tests in Austria, and even under all that masking, the test mule looks truly menacing.

From this set of photos, one can clearly make out the huge kidney grille, hexagonal “corona ring” LED DRLs and huge cross-drilled discs clamped with M-specific blue calipers. Of course, the front and rear bumpers are unique to the M model, the former featuring large air intakes that feed cool air into several coolers.

On the side, it will get the familiar steeply-raked roofline as the new X4, tapering down to meet seamlessly with the tailgate. Again, it’s still impossible to tell how the rear section will look through all that camo, but it most likely won’t veer too far from the X4. The tail lamps however, appear much sleeker compared to the G05 X5, and they feature a curved LED strip like that of the new 8 Series.

Inside, expect the cabin of the X5 to be carried over, meaning it should get a fully digital M-specific instrument cluster, a high-res 12.3-inch Control Display, head-up display, BMW Live Cockpit Professional and the latest iDrive control system, among other things.

Last but not least, the engine. While nothing is set in stone yet, the F96 X6 M could very well share the same S63B44T4 4.4 litre twin-turbocharged V8 as the F90 M5. In the super sedan, the engine produces 600 PS from 5,600 to 6,700 rpm and 750 Nm of torque between 1,800 and 5,600 rpm, and it’s paired with the eight-speed M Steptronic torque converter automatic transmission.

BMW’s famed xDrive all-wheel drive system should be standard here, so expect blistering pace with a century sprint time of under four seconds. Comparatively, the same engine propels the F90 M5 from zero to 100 km/h in 3.4 seconds. So, are you excited about the new X6 M?
