There's no doubting the Denali's extrovert target audience, as it gets an aggressive-looking grille, distinctive LED headlamps and brash 23-inch alloy wheels.Inside, there's a spacious and luxuriously appointed cabin. The four-door 'crewman' cab comfortably seats five, while leather and aluminium are used extensively for the chairs and dashboard. Look down the flanks and you'll spot the bulging wheel arches and aluminium 'gills' in the front wings.
GMC Denali XT
Denali XT is based on GM's Zeta platform which is also used for the new Pontiac G8 and Chevrolet Camaro.The XT also gets more optimizations to reduce energy losses. Active Thermal Management transfers heat among different components to improve efficiency while a low friction axle reduces parasitic losses. In this case a four-door, four-seat passenger area sits in front of a 55" long x 47.5" bed. Under the floorpan sits the same two-mode hybrid transmission used in the GMT900 full-size SUVs and pickup trucks.The Denali XT seats four. The high-cowl 
vehicle architecture enables higher seating positions, allowing the couple distance between front and rear occupants to be reduced without compromising knee room.The Denali XT has an estimated payload capacity of 1,100 pounds (499 kg) and a towing capacity of an estimated 3,500 pounds (1,587 kg). This capability is delivered through unique vehicle and powertrain integration, where the multiple modes of GM's two-mode hybrid system provide towing capability.
