3 days ago, we looked at the BMW M Diesel. Here’s a video of all of them in action. They are the BMW M550d xDrive (saloon and touring), BMW X5 M50d and the BMW X6 M50d that is powered by the new 3.0 liter in-line-6 diesel engine with three turbochargers. Output comes in at 381-hp at 4,000 rpm and maximum torque is 740 Nm available from 2,000 rpm to 3,000 rpm. All models are mated to a 8-speed automatic transmission and returns petrol M Performance but kinder to the wallet.
