BMW X6 M50d: Will the madness never end? (photos)
The engine that gives this X6 its M badge is a 3-liter straight six-cylinder engine, pretty standard stuff for a diesel. But the secret sauce is three turbochargers, two low-pressure and one-high pressure. Total output comes up to 381 horsepower and, wait for it, 545 pound-feet of torque. It is that sort of twist that gets the X6 M50d to 60 mph in 5.3 seconds.
