Rumors of BMW M launching a diesel model have been circulating for over a year, and confirmation has finally arrived in the form of not one, not two, but four M-fettled oil-burners, each sporting all-wheel drive and the oft-rumored tri-turbocharged 3.0-liter inline six. And before you get excited, none of them are slated for sale in the U.S. – this is a Euro-only affair.
So with that unfortunate fact out of the way, let’s get to the details.
The new M models come in the form of the M550d xDrive sedan, M550d xDrive touring, X5 M50d and X6 M50d. Each makes use of a 3.0-liter inline-six common-rail diesel with the aforementioned trio of turbos specifically developed for the M Performance range. Output is rated at 376 horsepower at 4,000 rpm and 545 pound-feet of torque available from 2,000 to 3,000 revs. If you’re keeping track at home, that’s a bump of 80 hp and 103 lb-ft over the 535d and 74 hp and 103 lb-ft more than the 3.0-liter mill fitted to the diesel X5 and X6.
Each model comes equipped with an eight-speed automatic gearbox and standard xDrive AWD, allowing the M550d sedan to hit 60 mph in 4.6 seconds – just four tenths of a second off the all-new M5’s 0-60 run. You read that right. The M550d Touring hits 60 in 4.9 seconds, with the X5 M50d and X6 M50d passing the mark in 5.4 and 5.3 seconds, respectively. All models are limited to 155 mph and fuel consumption ranges between 6.4 liters/100km and 7.7 liters/100km.
Interestingly, the M-ified diesel 5ers ditch the standard electromechanical steering for a hydraulic system that’s derived from the M5, and both the X5 and X6 variants uses systems similar to those on the X5 M and X6 M.
And if you’re wondering why we won’t see these M diesels here in the States, blame the necessity to reengineer the SCR (selective catalytic reduction) systems to make them comply with emissions standards across the country.
