The BMW XM has been filmed putting its hybrid power to the test at the fearsome Nurburgring. And if you were a little concerned about what the drivetrain would sound like, the news is good.

In the video, the car can be seen driving slowly on the streets around the track, and the newly-developed, electrically-assisted V8 powertrain sounds pretty darn good. The standard XM will get 644 hp (480 kW / 653 PS) of power and 800 Nm (590 lb-ft) of torque and 50 miles (80 km) of electric range, while a higher-performance model will get up to 738 hp (550 kW / 748 PS) and 1,000 Nm (737 lb-ft) of torque.

It’s unclear exactly which model has been seen testing here but the non-carbon-fiber roof may suggest that this is a lower-trim model. The more powerful 738 hp models are expected to feature a carbon-fiber roof for a lower center of gravity, though this sounds a bit ironic, given the size and weight of BMW M’s upcoming model.

Previously seen at an airport with even less camouflage, the design of the production model is likely to hove pretty closely to that of the XM Concept. That means that the automaker is sticking with the huge grille, the angular design, and the small headlights. Even the BMW M1-aping roundels could be seen on the spied vehicle.

Production of the vehicle is expected to begin this December in Spartanburg, South Carolina.
