The closest BMW got to producing a police cruiser for American law enforcement officers was in March of 2010, when the German automaker agreed to supply clean-diesel engines for Carbon Motors' E7 patrol car.
The BMW Group would have supplied a 3.0-liter, 6-cylinder engine with cooling and exhaust gas systems and automatic transmissions for the E7, a project now clinging to life support after the company was denied a federal loan to help finance production.
