It's been a busy year so far for BMW as they continue fine-tuning their cars for release later this year. Aside from the BMW M8 convertible, the X4 M was also seen doing laps around the demanding Nurburgring Norsdschliefe. With numerous sightings since last year, the BMW X4 M might arrive sooner than later.
There's not much new in this latest batch of photos. Given that the world has seen the non-M X4, there is a better idea of what the high-performance X4 will look like. Expect a more aggressive front fascia with deep air intakes. The bumpers also have a different design from the standard M Sport kit affair. To accommodate the M-tuned suspension, fenders have been widened and the crossover's height lowered.
Peeking through the wheels are big brake calipers, and cross-drilled rotors. For now, it is yet to be known if the car is running on production wheels since they are currently mis-matched. Moving to the rear, indicators that this is the X4 M are a set of large, quad exhaust tips, and prominent lip spoilers on two parts of the rear hatch.
As mentioned before, our spies say that it will be a new engine dubbed the S58. The straight-six engine is boosted by two turbochargers with power output is pegged at 450 PS. It will then likely shift via a sports-tuned eight-speed automatic transmission. xDrive all-wheel drive will be standard and likely to have been recalibrated for the car's purpose.
