Besides the power boost, the tuned BMW XM by Manhart (MHXM 900) also offers a carbon fiber body kit, new wheels, chassis enhancements, and a tweaked cabin

The upgrade package is known as the MHXM 900 and is based on the flagship XM Label Red. From the factory, this model delivers 738 hp and 738 lb-ft (1,000 Nm) of torque thanks to a powerful 4.4-liter twin-turbocharged V8 and a 197 hp electric motor. But Manhart managed to draw even more power out of the electrified powertrain.

Don’t you just love it when an aftermarket tuner takes an already divisive car and adds a bit more divisiveness to it? That’s precisely what Manhart has done with the BMW XM, christening the resulting product the ‘MHXM 900’.

It’s a reference to its 900hp (912bhp) output, which is over 150 more than the factory-tuned range-topper produces. The eight-speed M Steptronic gearbox also channels around 885 torques to all four of Bavaria’s castle on wheels. Yeah, wild.

That EV is a model sold at a “reasonable” price. At the other end of the automotive spectrum, BMW is experiencing the same issue with its XM SUV. That plug-in hybrid performance SUV is priced quite a bit higher than the little Fiat. But its sales are equally catastrophic.

The BMW XM is one of the most controversial vehicles to hit the automotive scene in recent years. Aside from its hefty price tag and niche positioning, it offends enthusiasts on many levels - from its polarizing styling to its bizarre positioning as the BMW M halo car.
