Quad-Turbo BMW X6 M50d Is No Slouch, We’ll Give It That

The BMW X6 M50d’s quad-turbocharged engine delivers 394 hp and 560 lb-ft.

The guys over at AutoTopNL recently had the opportunity to test out the BMW X6 M50d on the German Autobahn and found it pretty quick, albeit not as accelerative as many of the other vehicles they tested.

The most intriguing aspect of the X6 M50d is that, just like other models such as the BMW 750d and M550d, it uses a 3.0-liter inline-six diesel engine with four turbochargers. This engine is good for 394 hp at 4,400 rpm and 560 lb-ft (760 Nm) of torque at 2,000 rpm.

While testing the SUV, the publication was able to hit 62 mph (100 km/h) in a touch over 5 seconds (no specific time is provided) which is pretty respectable considering the roads were damp. From there, the X6 M50d continues to build speed and eventually hits its limited top speed of 155 mph (250 km/h).

As cool as BMW’s quad-turbo engine is, it won’t survive for much longer as research and development boss Klaus Froehlich revealed in January that it won’t be replaced because it is too expensive and too complicated to build with the four turbos.

A number of other BMW engines are on the chopping block. These include the 1.5-liter three-cylinder diesel used by vehicles such as the Mini Cooper D, as well as BMW’s flagship V12 engine that powers the M760Li. Fortunately, the V12 will probably stick around until 2023. Froehlich also said that it is becoming hard for BMW to justify keeping its twin-turbo V8 around now that it has developed a six-cylinder hybrid with 600 hp.
