Beating their official debut at the Los Angeles Auto Show by a few weeks, BMW has unveiled its newest super SUV and CUV – the 2015 X5 M and X6 M. The duo continues to rely on the company's beastly twin-turbocharged 4.4-liter V8, which now produces 567 horsepower (up from the previous 555) and 553 lb-ft of torque (up from 500) with peak torque now arriving between 2,200 and 5,000 rpm. Both receive an eight-speed Steptronic transmission and come mated to an xDrive AWD system.

Weighing in at over 5,000 pounds, both new Ms promise to sprint from 0-60 mph in 4 seconds flat. Despite the increase in power and performance, BMW says the two models benefit from a 20 percent reduction in emissions and fuel consumption on the European cycle. From a styling point of view, the X5 M and X6 M receive a host of aesthetic benefits to differentiate them from their non-M brothers. These include 21-inch wheels, quad exhausts, side gills, large air intakes, flared wheel arches and more. Inside, the M's are given a new steering wheel with aluminum paddle shifters, new sports seats and more M equipment throughout.

Both the X5 M and X6 M ride on a double-wishbone front suspension and self-leveling rear one, with dynamic dampers offering three modes. The 21-inch wheels are matched to Michelin Pilot Super Sport UHP tires, measuring 285/35/21 up front and 325/30/21 in the rear. US pricing will start at $99,650 for the BMW X5 M and $103,050 for the X6 M.
