BMW showed off their four new trucker fuel M cars at Geneva, showing that if Germans are going to dilute a brand, at least they're going to do it with ridiculously advanced technology.
BMW is launching a new high-performance, 3.0-liter inline six for its M cars. No surprise yet. It also has three turbochargers, produces 381 hp and 546 lb-ft of torque, and only revs to 5,400 rpm. Ruh Roh. Yes, it's a diesel.
