The BMW M550d xDrive is the automaker's latest performance diesel.

Its 3.0-liter I6 diesel engine puts out about 400 horsepower and 561 pound-feet of torque.

Whereas the last BMW I6 diesel had three turbochargers, this one has four.

One high-pressure unit starts spinning, then it's aided by two low-pressure turbochargers, with yet another high-pressure turbo kicking in after that.

Of course, it's still a BMW, so it's loaded with all sorts of fancy trimmings.
