Recently BMW revealed its new M Performance Diesel models, the M550d, X5 M50d, and X6 M50d, all of which are powered by the German automaker’s new 3.0L six-cylinder, tri-turbo diesel engine with 381-hp and 546 lb-ft of torque.

Unfortunately none of America will get to experience the new powerplant since BMW doesn’t find them fitting in the US market, but it appears as though AMG doesn’t find performance-minded diesel engines fitting in any market. The high-performance division for Mercedes-Benz vehicles, AMG head boss Ola Kallenius recently said that they have no plans to follow its German automaker rival in producing diesel engines, saying that it would introduce too many compromises to its performance-focused lineup.

“The technology of performance gasoline engines is converging with diesel tech. Direct injection, downsizing and turbocharging are all having an effect. We looked at diesel a few years back, but petrol engines have obvious benefits of sound, weight, agility and response,” Kallenius said.

We’re not ones to argue, considering AMG has a new 5.5L V8 Biturbo powerplant that puts out 544 to 571-hp with up to 664 lb-ft of torque. You could say some of us subscribe to the belief that if you’re looking for pure performance, fuel efficiency shouldn’t be of concern.

Rumors are now spreading rampantly since BMW released its teaser video of the first-ever BMW M Diesel in the form of their X6 crossover. It is now widely believed that the X6 M50d will come with a tri-turbo, six-cylinder diesel powerplant pushing out 381-hp with a healthy 545 lb-ft of torque.

The folks over at BMWBlog are also reporting that the X6 M50d will go 0-62 mph in 4.9-seconds and that production of the model will begin April of 2012. An option for the X6 M50d also leaked out; the M division will also offer a revised front hood.

Perhaps even more interesting is that BMW’s M550d xDrive will feature the same powerplant, making it go 0-62 mph in just 4.7-seconds and could get 38-mpg. The M550d is expected to go into production in March 2012 but will only be offered in Europe. Whether or not the X6 M50d shares the same fate is unknown, but given how slowly diesels are being embraced in America, we shouldn’t hold our breath.
