BMW has officially unveiled the 2015 X5 M and X6 M, ahead of their debut at the Los Angeles Auto Show.

Looking downright menacing, the high-performance crossovers have an aggressive front bumper, a revised grille and aerodynamic side skirts. The models also have ventilated front fenders, aerodynamic side mirrors and 21-inch lightweight alloy wheels with Michelin Pilot Super Sport UHP tires. The sporty styling continues out back as there's a distinctive rear bumper and a diffuser which is flanked by a four-tailpipe sports exhaust system.

The styling changes continue in the cabin as the models have Merino leather sport seats, a revised instrument cluster and a leather-wrapped M steering wheel with aluminum gearshift paddles. Other highlights include a leather-wrapped dashboard, an Alcantara roof liner, M-brand door sill plates and aluminum trim. If that's not impressive enough, the models also boast contrast stitching, embossed headrests, a four-zone automatic climate control system and a Harman Kardon audio system.

Both models are powered by a twin-turbo 4.4-liter V8 engine that develops 567 bhp (423 kW) and 750 Nm (553 lb-ft) of torque. It is connected to an eight-speed M Steptronic transmission and an M-specific all-wheel drive system which enables them to accelerate from 0-100 km/h in 4.2 seconds before hitting a limited top speed of 250 km/h (155 km/h).

Speaking of performance, the crossovers also have an M Servotronic steering system and a sport-tuned suspension that reduces the ride height by 10mm. There's also a high-performance braking system (with Dark Blue metallic calipers) and a Dynamic Damper Control system with three different modes: Comfort, Sport and Sport+.

Both models will go on sale in the United States next spring and pricing starts at $99,650 for the X5 M and $103,050 for the X6 M.
