BMW has unveiled its X3 M and X4 M in prototype form, the clad units making their first public appearance at last weekend’s DTM race at the Nurburgring.
Previewing the series production models, the vehicles feature a new front bumper with a large air intake and side inlets, complete with honeycomb mesh inserts. Along the sides, the flared wheel arches to accomodate a wider track seen in spyshots can be found, as well as aerodynamic M-specific side mirrors.
An uprated performance braking system also makes its way on, denoted by the presence of blue calipers, while changes at the back see a reprofiled bumper and four tailpipes integrated into the rear apron, along with a new spoiler.
The automaker hasn’t revealed what the interior looks like, but expect the cabin to be dressed up with the usual M-style treatment for the upholstery, gearlever and steering wheel, among other things. Technical and performance specifications haven’t also been divulged, the company only stating that both will be equipped with a “newly-developed straight six-cylinder engine with M TwinPower Turbo technology and high-revving characteristics.”
Previous reports have indicated that the unit will be the new S58 3.0 litre twin-turbo straight-six, which will also find its way on to the next M3 and M4, with outputs set to exceed 450 hp in the SAV applications.
Aside from the new mill – and the likelihood of an eight-speed automatic transmission, given the M5‘s switch to that – the duo will come with an M xDrive all-wheel drive system based on that seen on the M5. The cars are also set to feature an active M rear axle differential as well as a sportier suspension.
