Trust us when we say this was a straightforward BMW 2 Series Coupe in the humble 220d specification. It now has the heart of an M Performance diesel SUV as the original four-pot engine has been removed to make way for another diesel, which is much bigger and with many more turbochargers. Check out the unofficial M2 50d, fitted with a tri-turbo inline six-cylinder diesel engine borrowed from an older X5 M50d.
The impressive build represents the work of Gary Martins, a former BMW master technician, who now runs his own business called Grease Monkey Motors. Suffice it to say that he is a big fan of BMW and knows his stuff. The oil-fired M2 might seem like a sacrilege to M fans, but with the company having a history of M Performance diesels, it might not be such a far-fetched idea.
The larger engine was fitted without requiring any modification to the bodywork. Having received nitrous treatment as well as water-methanol injection, the 3.0-liter diesel now develops 583 horsepower (435 kilowatts) and 1,070 Newton-meters (789 pound-feet) of torque. That’s quite the hump of the original 381 hp (284 kW) and 740 Nm (546 lb-ft).
The donor car 220d gave way to a much more aggressive coupe with the front bumper borrowed from the M2 competition. A quad exhaust has also been added to mimic the look of a real M2, while the M Performance carbon fiber rear spoiler accentuates this is no longer an ordinary 2-Series diesel coupe. Gary Martins explains that the rear fenders had to be widened to fit the larger wheels, while the rear bumper and front fenders came straight from an M2.
A bespoke carbon fiber hood hides the diesel beast inside, and the trunk lid is also made from the same lightweight material. Large front brakes borrowed from the M5 (F10) and rear from an M4 provide the stopping power needed after the engine is upgraded. Speaking of which, the tri-turbodiesel now works with a transmission that came from a 330d but modified to handle the extra torque.
The list of changes goes on forever as a 330d also lent it a differential and a shortened driveshaft. Gary Martins mentions that the driveshaft is from an M135i. Inside there are original M3 front seats and a roll bar replacing the rear bench seat. As the cheerful tail footage shows, the M2 50d remains a rear-wheel drive machine, unlike the official cars with the M50d badge which all come with xDrive.
It can be used not only in everyday life, but also as a track car and even for drag racing with few modifications. The high-performance M2 diesel will be put to the test in early September at the 11e edition of the Simola Hillclimb event in Knysna, South Africa.
