GMC has taken the wraps off the 2015 Yukon Denali and Yukon XL Denali.

Set to become the brand's range-topping models, the Denalis are distinguished by a mesh grille and high-intensity discharge headlights with C-shaped LED daytime running lights. The models also have bright chrome trim and 20-inch alloy wheels.

The premium styling carries over to the cabin as it is awash with premium leather upholstery and wood trim. Other notable highlights include ambient lighting, contrast stitching, active noise cancelation technology and a Bose sound system. There's also a push-button ignition, a head-up display and an IntelliLink infotainment system.

Power is provided exclusively by a 6.2-liter EcoTec3 V8 engine that develops 420 bhp (313 kW) and 450 lb-ft (610 Nm) of torque. It is connected to a six-speed automatic transmission which can be paired to an optional all-wheel drive system.

The 2015 Yukon Denali and Yukon XL Denali will go on sale early next year and pricing will be announced closer to launch.
