This BMW X4 M prototype was spotted doing some performance testing at the Nurburgring recently and the newcomer will give the X4 range a massive performance boost. Here's what you need to know andwhat the forthcoming BMW X4 M will sound like.

The performance SUV market continues to grow and this time it appears that BMW will be launching an X4 M. Spotted at the Nurburgring was a prototype BMW X4 M undergoing performance testing. The all-new BMW X4 was recently launched and we got a taste of what's to come as we got behind the wheel of the new M40d. However, this new X4 M model takes things up a notch.

The step up from X4 M40 to X4 M will be considerable, and the new car is set to get a revised chassis with a sportier suspension setup, tweaks to the steering and the fitment of bigger brakes. In terms of engines, we think the BMW X4 M will use the current S58 motor, which is a 3.0-litre straight six motor based on the mill which powers the current M3 and M4. Outputs are estimated around the 340 kW mark and thanks to a combination of xDrive and launch control, it should be able to hit 100 kph in under 4 seconds.

In terms of rivals, this new BMW X4 M will be going up against the Mercedes-AMG GLC 63 and the Audi SQ5. It is expected that this powertrain will also spawn an X3 M derivative.
