BMW M550d & X6 M50d performance specs leaked - rumors

Performance and efficiency combined

New details are starting to emerge about the BMW X6 M50d and M550d xDrive.

First up, the X6 M50d is expected to go into production in April with a tri-turbo 3.0-liter six-cylinder engine that develops 381 PS (280 kW / 375 hp) and 740 Nm (546 lb-ft) of torque - 40 Nm (30 lb-ft) more than originally speculated. This could enable the model to accelerate from 0-100 km/h in 4.9 seconds which is just 0.2 seconds slower than the standard X6 M.

The report also indicates the M550d xDrive will use the same engine and accelerate from 0-100 km/h in 4.7 seconds. In terms of efficiency, the sedan is expected to average 6.3 L/100 km (37.3 mpg US / 44.8 mpg UK) with CO2 emissions of 165 g/km. If everything pans out, it will roll off the assembly line in March and be offered exclusively in Europe.

With all that 'power' under the hood its very unlikely many will care much for fuel consumption which makes me very skeptical about the whole tripple turbo set up. Sure it may sound cool to your mates but will the engine last when you give it the beans so often?

I'm also probably gonna get hung for this, but why is the video blurred? Is it because the X6 is so gut wrenchingly ugly? (OK OK, I know the real reason, I ain't that stupid), but just a random thought. (^^)

Can someone please explain me how it possible that a 555hp SAV is doing 0-100 in 4.7 seconds while the same car with only 375hp is doing the same thing in 4.9?
