Cars are Andrew's jam, as is strawberry. After spending years as a regular ol' car fanatic, he started working his way through the echelons of the automotive industry, starting out as social-media director of a small European-focused garage outside of Chicago. From there, he moved to the editorial side, penning several written features in Total 911 Magazine before becoming a full-time auto writer, first for a local Chicago outlet and then for CNET Cars.

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.

You can't see much through an engine cover, sadly.
