The BMW X4 M Performance test mule has been spied without camouflage, and it turns out it looks exactly the same as the standard 35i with the optional sports package.
The only difference is the single exhaust pipe on both sides of the car, as opposed to the dual pipes on the 35i.
It will use the same six-cylinder engine as the 35i, but in the X4 M Performance car, power will be boosted to somewhere between 250kW and 280kW.
