BMW X6 M50d: Performance & Economy figures revealed

With the BMW X6 M50d confirmed as on its way, we now get news on its performance and economy.

We’ve been reporting the likelihood that BMW will drop their new three stage turbo diesel in to the X6 for a long time now, and that’s a racing certainty after BMW teased what is almost certainly the X6 M50d this week with a video. But what about power, performance and economy on the M50d?

We’d already had an educated guesstimate of what we expected from the M50d in previous stories. We reckoned the three stage turbos in the 3.0 litre V6 would yield around 380bhp and 525lb/ft of torque, and that if you weren’t blatting around you could expect the right side of 40mpg.

Now the guys over at BMWBlog – usually well-informed on all things BMW – claim to have the inside line on power and performance figures from a BMW insider, and they’re pretty close to our figures.

It seems the X6 M50d will come with 381bhp, 545lb/ft of torque and will get to 62mph in just 4.9 seconds. That’s just 0.2 seconds behind the X6M, making what is, to all intents and purposes, a diesel X6M very close in performance terms to its petrol-engined sibling.

Of course, the performance will be delivered differently. Instead of a linear progression with the 550bhp in the X6M, you’ll get a wall of twist that will propel you forward, but run out of breath more quickly. But around town and powering away the M50d will be awesome.

It will also be parsimonious, at least as long as you can resist the temptation to move the road below you with the mountain of torque (up around 10 per cent on the X6M) on tap. Official economy is said to be 45mpg, more than twice as many mile per gallon as the X6M, with emissions at 165g/km.

It’s have your cake and eat it time with the BMW X6 M50d. Appealing, very appealing.
