The Denali bade is being shrunk to fit on smaller vehicles. GMC is expanding its exclusive Denali sub-brand with the debut of the 2013 Terrain Denali, which brings a new level of style and power to the luxury small sport utility.  Up until now, the Denali name had been associated almost exclusively with GM’s largest and most powerful SUVs. “Denali is growing fast,” said Tony DiSalle, U.S. vice president of GMC Marketing. “With seven different models, sales for this brand within a brand increased 79 percent from 2010 to 2011. With this in mind, the decision to create a more-upscale Terrain was an easy one.”
With the introduction of the Terrain Denali, GMC also announced a new 3.6-liter V-6 engine with direct injection and continuously variable valve timing will replace the current 3-liter V-6 engine in Terrain lineup for the 2013 model year.  Certified at 301 horsepower  and 272-foot pounds of torque, this engine makes more power and torque, but is expected to deliver fuel economy equal to its predecessor.
 The Terrain’s standard Ecotec 2.4-liter I-4 with direct injection and continuously variable valve timing is also available for buyers looking to combine Denali’s high-end appointments with a best-in-class 32 miles per gallon in highway driving. Front-wheel drive is standard on Terrain Denali, with all-wheel drive available for both engines.  
Inside and out, the 2013 Terrain Denali features high-end details. Models with the 2.4L engine feature 18-inch wheels, while the V-6 engine is paired with 19-inch wheels. Other Denali-specific exterior features include, signature chrome grille, satin chrome accents, body color front and rear fascias, body color rocker panels with satin chrome molding, new headlamp and taillamp designs
Terrain Denali’s cabin updates are highlighted by soft-touch Jet Black leather, which lines the seats and door inserts. Contrast stitching and red accent lighting contribute to an inviting interior.
 The Denali aloo features Terrain Denali comes standard with many of GMC’s leading technologies, including a color touch radio with the IntelliLiink infotainment system features a reconfigurable home screen; intuitive voice commands; Bluetooth smartphone integration; control of streaming internet radio apps such as Pandora and Stitcher; and iPod controls with Gracenote music database technology.
Forward collision alert and lane departure warning are standard on Terrain Denali. They use the industry’s first single-camera crash-avoidance system to visually and audibly warn drivers when a collision is imminent or the vehicle crosses a lane marker. In addition, side blind zone and rear cross traffic alert help avoid collisions by using radar to watch spots the driver may not be able to see – and provide visible and audible warnings.
