BMW X6 M50d: Will the madness never end? (photos)
Making an M version of the X6 seemed an impossible challenge, but BMW proved it could be done. The X6 M handles like a much smaller car. But now BMW is coming out with an X6 M powered by a diesel engine, as if its engineers are constantly seeking a higher mountain to climb. Along with the X6 M diesel, BMW has also come up with the X5 M50d and two 5 Series M diesels, all using the same engine.
