GMC's five-passenger midsize crossover, the Terrain, has added an upscale Denali trim level for 2013, turning this into quite a fancy vehicle.Overall, the popular Terrain comes in 10 trim levels, including five all-wheel-drive models. Prices range from $26,235 for very basic to $36,675 for the Denali AWD version, which was my tester.The Denali AWD features the signature chrome grille, a new headlight design, body-color fascias and rocker panels (with satin chrome trim), chrome door handles, heated power mirrors, roof rack side rails, rear skid plate, revised taillights and dual chrome exhaust tips.Also included on the Denali are advanced camera-based safety features offered as options on the other Terrain models. A camera mounted between the windshield and the rearview mirror supplies data to the lane-departure warning system, collision-alert system and radar cruise control.Collision alert warns the driver with a very loud alarm and pre-charges the brakes to help stop the vehicle quickly if needed. It works, but is startling the first time it happens.The Denali comes with a blind-zone alert integrated in the side mirrors, and a rear cross-traffic alert that works in concert with the rearview camera. The cross-traffic alert comes in handy, especially since the rear side pillars are large and limit visibility when backing out of parking spaces.Illuminated sill plates, a power passenger's seat and unique wheels are other Denali-exclusive items.The tester came with an engine upgrade package for $1,750, which included the optional 3.6-liter V-6 and 19-inch, six-spoke, satin-chrome wheels. The standard engine is a 182-horsepower, 2.4-liter four-cylinder engine. With the V-6, there is 301 horsepower and 272 foot-pounds of torque.With the standard six-speed automatic transmission, my Terrain with the V-6 was EPA rated at 16 mpg in the city and 23 on the highway. Using cruise control where possible and prudent driving techniques always, I managed 20 mpg on average.The Denali model is extra special inside, with a soft-touch French-stitched instrument panel and dash, leather-wrapped steering wheel with mahogany accents, smoked mahogany accents on the dash and door panels, embossed Denali logos on the front seats, heated front seats, and eight-way power driver and front passenger seats with lumbar support. The driver's seat has memory settings, including settings for the outside power mirrors.Capable of towing 3,500 pounds, my tester came with the trailering package for $350.There is 31.6 cubic feet of cargo space behind the rear seat, but that can be expanded by folding the rear seat back. The rear seat also moves fore and aft a total of eight inches to create either more legroom or more cargo area.Rear legroom is listed as 39.9 inches with 39.2 inches of headroom. Legroom in the front is 41.2 inches, with 40.4 inches of headroom.The rear seat holds three passengers comfortably, including the middle seat, and has lower anchors and tethers for child seats in all three positions. The front row has side-impact air bags, and both rows have roof-mounted side-curtain air bags with rollover protection.With these features, the Terrain earned the Top Safety pick designation from the Insurance Institute for Highway Safety in 2012.My tester had an impressive navigation system with lots of additional information, part of a package including Intellilink for $795.The system had numerous route options such as "use ferries," "use tunnels," "use car train," fastest, shortest and Eco. There were numerous detailed point-of-interest listings such as office supply, electronics and grocery stores, and other miscellaneous information such as weather forecasts and movie showtimes.Terrain also comes with OnStar Directions and Connections with automatic crash response and turn-by-turn navigation.The Intellilink system provides hands-free smartphone integration with Bluetooth audio streaming and voice-activated audio controls. The standard audio system included a seven-inch color touch screen, CD/MP3 player, auxiliary input and USB port.Seven exterior colors are offered on the Denali: Quicksilver Metallic, Summit White, Ashen Gray Metallic, Champagne Silver Metallic, Carbon Black Metallic ($495), Crystal Red Tintcoat ($495) and Iridium Metallic ($195).My vehicle had a Jet Black soft-touch leather interior with French stitching and red accent lighting. My tester also had a cargo package for $235, which included a cargo net, cargo cover and luggage rack center rails.Total sticker price for my Terrain Denali was $40,425, including $825 freight and $3,325 in options.The automotive columns of Emma Jayne Williams appear weekly in the Star-Telegram.
