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% 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 in 2WD form 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-over-shock front suspension, rack-and-pinion steering and a premium interior that bolsters the vehicle’s comfort, quality and capability.
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 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.
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 V8 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 V8 engine to operate in its more economical V4 mode for longer periods.
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.
The hybrid system provides seamless, dependable power on demand in an efficient package. In fact, its electric motor is less than half the size of those in single-mode hybrid systems. This technology was developed and is still used in fleets of hybrid transit buses in more than 70 North American and European cities. Scaled down for use in passenger vehicles, the two-mode system delivers fuel savings where it is needed most – in large vehicles with high levels of capability. The two-mode system was first introduced on the 2008 Yukon Hybrid. It is a core part of GM’s energy diversity efforts, centered on reducing dependence on petroleum, improving fuel economy, reducing emissions and minimizing the automobile’s impact on the environment.
In addition to increased fuel economy, the Yukon Hybrid’s electrically variable transmission also provides tremendous trailering capability, enhancing driving smoothness and quality when towing.
Electric drive is enabled up to 27 mph, saving fuel even when the truck is towing a trailer.
The EVT incorporates grade braking and tap up/tap down shift control. It also benefits towing on curves or lower-speed back roads, as exceptionally smooth gear transitions eliminate the “shift shock” torque disruption that can occur during abrupt shifts, such as when slowing or braking.
In addition to the eight-year/100,000-mile warranty on the Yukon Hybrid’s Energy Storage System, GM’s five-year/100,000-mile Powertrain Limited Warranty is offered.
