New BMW M Performance models – with 375bhp diesel engines – will be available in June. The new high-performance versions of the X5 and X6 SUVs are the first in a range of new Performance models that BMW will introduce.
The new X5 M50d xDrive and X6 M50d xDrive use a new 3.0-litre diesel engine, with three turbochargers. Maximum power is 375bhp; peak torque is a mighty 546lb ft.
An eight-speed automatic gearbox and four-wheel drive are standard. BMW quotes a 0-62mph time of 5.4 seconds for the X5 and 5.3 seconds for the X6.
BMW’s usual range of Efficient Dynamics features is fitted, including an engine stop-start system. Average fuel economy is 37.7mpg for the X5 M50d and 36.7mpg for the X6 M50d.
Both models have self-levelling rear air-suspension. BMW’s Adaptive Drive system – an adjustable suspension set-up with active anti-roll bars – is standard for the X6 and optional for the X5. All versions come with bespoke steering and suspension settings and upgraded engine and transmission mounts.
Externally, the new models have a similar makeover to BMW’s M Sport models, with deeper, more aggressive bumpers and side sill extensions.
M Performance models gain a special metallic grey finish for the door mirrors and air intake grilles, bespoke alloys and an M Performance badge on the bootlid. Inside, there’s Alcantara-and-leather upholstery, and special materials for the headlining and trim.
BMW is also launching a four-wheel-drive version of the BMW 5 Series with the same engine and a similar makeover, called M550d xDrive, but it’s not due in the UK until at least 2015. BMW has denied rumours that a rear-wheel-drive version of this model will be produced for the UK.
Both M Performance models go on sale in June: the X5 M50d will cost £60,325 and the X6 M50d – which joins an updated X6 range – will be £62,260.
