The BMW X3 M has been spied again, this time during cold weather testing – previewing Munich's rival to the Mercedes-AMG GLC63.
The front end, side skirts, and rear are all heavily camouflaged, but you can reasonably expect to see more aggressive air intakes at the front, sculpted skirts and a faux-diffuser with quad-exhaust outlets at the back. There's also black and white tape obstructing the mirrors, suggesting the aero-style mirrors from current M cars will carry over.
Although there's no hard-and-fast word on how much power it'll make, we'd suggest the Mercedes-AMG GLC63 and its 375kW could be a good benchmark.
At the moment, the most powerful X3 is the M40i, with 265kW and 500Nm of torque from 3.0-litre inline-six engine.
