Prior to their debut at the Los Angeles Auto Show, the new M versions of the BMW X5 and X6 show up online, surrendering all the details on their specs and pricing. The new models are fairly similar to the old ones, but enhanced in almost every way.

So while you still get the same 4.4 liter V8 twin-turbo engine, in the 2015 BMW X5M and X6M it makes 567 horsepower and 553 lb-ft of torque. Thanks to a new eight-speed M Steptronic transmission with Drivelogic, the big SUVs can now accelerate from 0 to 60 mph in 4.0 seconds dead.

As with the previous models, 2015 BMW X5M and X6M are distinguished over standard models by a pretty massive body kit consisting of prominent aero kits, large intakes, and 21-inch M light-alloy wheels. Inside the cabin too you will find evidence of M intervention in form of  M instrument cluster, M leather steering wheel with aluminum gearshift paddles and M gearshift lever.

Another advantage of BMW X5M and X6M over normal models is the combination of xDrive intelligent all-wheel drive and Dynamic Performance Control. The system, comprising an electronically controlled multi-plate clutch, will result in optimum traction and agility regardless of driving condition.

These are the important headlines for the new M-powered BMW SUVs. As for the pricing, 2015 BMW X5M will be offered at $99,650 and the X6M will start at $103,050, including $950 Destination and Handling. Both models will arrive in US showrooms in the Spring of 2015.
