GMC Yukon Denali Hybrid- Provides full-size luxury and capability with more than 50-percent increase in city fuel economy
- Powered by GM’s advanced, patented, two-mode hybrid technology
- Eight-year/100,000-mile hybrid powertrain warranty with no deductibles
The GMC Yukon Denali Hybrid arrives in May at Buick-Pontiac-GMC dealer showrooms. It joins the Yukon Hybrid and Sierra Hybrid pickup truck in the GMC hybrid lineup, making GMC the first manufacturer to offer three full-size hybrid models.
“The eight-passenger GMC Yukon Denali Hybrid goes just as far on a gallon of gas in the city as a much smaller, V-6 Toyota Camry sedan,” said Susan Docherty, vice president, Buick-Pontiac-GMC. “And in terms of fuel savings, the GMC Yukon Denali saves about 250 gallons of fuel a year over the Lexus GX 470.”
The GMC Yukon Denali Hybrid infuses a new level of luxury to the Yukon Hybrid introduced for the 2008 model year. Docherty said the number one consideration for those purchasing the GMC Yukon Hybrid is fuel economy (80 percent); followed by 66 percent for its environmentally friendly technologies and more than half because of its technological innovation.
Patented, industry-leading hybrid technology
GM’s most advanced hybrid technology drives the GMC Yukon Denali Hybrid’s superior fuel economy, performance and load-carrying capability. Powering this hybrid system is a fully integrated combination of two lightweight electric motors packaged in the transmission; an electronic brake emulator that provides blended regenerative braking; electric power steering and an electric air conditioning compressor.
The heart of the system is GM’s 6.0L Vortec V-8 engine with fuel-saving Active Fuel Management, late intake valve closing and variable valve timing technologies. It produces 332 horsepower (248 kW) and 367 lb.-ft. (498 Nm) of torque.
Unique hybrid exterior, luxurious interior
The Yukon Denali Hybrid rides on new 22-inch, eight-spoke, flangeless chrome wheels that make a unique Denali appearance statement.
Inside, designers filled the cabin with luxurious amenities such as standard 12-way power, heated/cooled leather-appointed perforated front seating and heated, second-row, leather-appointed bench seating. Buyers may choose an Ebony or Cashmere interior. The only three options on this fully equipped vehicle are a sunroof, rear-seat entertainment DVD system and side blind zone alert mirrors.
Enhanced connectivity includes standard OnStar with Directions & Connections and Turn-by-Turn Navigation, navigation radio with rear camera system, a Bose Centerpoint Surround Sound System and three years of real-time XM NavTraffic.
A comprehensive safety package of crashworthiness and crash-avoidance features includes front- and side-impact air bags, anti-lock brakes and StabiliTrak with traction control. The Yukon Denali Hybrid also is equipped with GM’s MagnaRide suspension, the first application of this advanced technology in a Yukon. MagnaRide uses magnetic particles in the shock absorber fluid to adjust the damping rate of the shock absorbers – based on road conditions and vehicle dynamics – to help keep tires in contact with the road.
MSRP starts at $59,185 (2WD) and $62,030 (4WD), including the destination freight charge of $950. Buyers may be eligible for a tax credit of up to $2,200.
