The GMC Yukon Hybrid broke ground with the world’s first production 2-Mode full hybrid propulsion system, which on the 2WD model offers 21 mpg in city driving — a 50-percent improvement over non-hybrid models.

The lineup now includes the distinctive Yukon Denali Hybrid, which infuses a new level of luxury into the efficient utility vehicle.

Along with exceptional fuel economy, the Yukon Hybrid and Yukon Denali Hybrid deliver full-size capability — up to 6,200 pounds of towing capacity (2WD) and standard eight-passenger seating capacity. Yukon Hybrid models are built on GM’s full-size SUV platform, which incorporates features such as a fully boxed frame, coil-overshock front suspension, rack-and-pinion steering and a premium interior that bolsters the vehicle’s comfort, quality and capability. Wide front and rear tracks enhance handling and lower the center of gravity for a more confident road feel.

The Yukon Hybrid was designed with safety in mind. It delivers a 360-degree safety system of occupant protection and crash-avoidance technology, with features such as standard StabiliTrak stability control system with rollover mitigation technology. For 2010, the long list of standard safety features is enhanced with the addition of front seat-mounted side air bags on all models.

DENALI HYBRID

The Yukon Denali Hybrid rides on unique 22-inch, eight-spoke, flangeless chrome wheels that make a stylish Denali appearance statement. Inside, designers filled the cabin with luxurious amenities such as standard 12-way power, heated/cooled leatherappointed 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 crash-worthiness 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.

TECHNOLOGY

The Yukon Hybrid’s fuel-saving performance is derived from GM’s advanced Electrically Variable Transmission (EVT) and 300-volt nickel-metal hydride Energy Storage System (ESS), which work with the standard 6.0L V-8 gasoline engine with Active Fuel Management (AFM) and late intake valve closing (LIVC) technology.

GM’s hybrid technology system not only enables the Yukon to launch and drive up to 27 mph on electricity alone, it allows the Vortec 6.0L V-8 engine to operate in its more economical V-4 mode for longer periods. As part of the vehicle’s emission control system, the ESS is warranted for eight years/100,000 miles.

In the Yukon Hybrid and Yukon Denali Hybrid, the hybrid system itself generates the electricity to propel the vehicle. When the brakes are applied or the vehicle is coasting, the electric motors in the hybrid system create electricity and store it in the 300-volt battery. This electricity helps move the vehicle.

QUIET AND SMOOTH

Integration of the hybrid system on the Yukon is seamless – the battery pack is beneath the second-row seat – and delivers a quiet driving experience.
