2008 GMC Yukon Hybrid

Overview

The new 2008 Yukon Hybrid features the world’s first two mode hybrid propulsion system in an SUV, allowing it to deliver the power and capability you expect of a full-size SUV, while providing up to a 25% improvement in overall fuel economy. Available in two- or four-wheel drive, the Yukon Hybrid’s impressive power derives from a 300-volt battery pack and two 60kW electric motors working in tandem with a 332 hp all-aluminum Vortec V8 Late Intake Valve Closing (LIVC) engine with Active Fuel Management.

Top Ten Features

  • 1. World’s first two-mode hybrid propulsion system This patented hybrid technology optimizes fuel economy for various driving conditions. First Mode: used at low speed and with light loads. Vehicle can operate in three ways: electric power only, engine power only, or a combination of electric and engine power. Second Mode: used primarily at highway speeds. Provides full engine power when conditions demand it, such as passing, trailer towing and climbing steep grades.
  • 2. Sophisticated control module Constantly monitors driving conditions to determine the amount of power or torque required at any given moment, and which of the two modes it should be operating in. Provides transparent and seamless operation.
  • 3. 300-volt battery pack and two 60kW electric motors The battery pack is automatically recharged by the V8 engine, and fits in the rear cargo area without compromising passenger room. The two electric motors provide exceptional rotational power and torque.
  • 4. 25% improvement in overall fuel economy The Hybrid’s Vortec V8 LIVC engine with Active Fuel Management works in tandem with the hybrid electrical system to produce exceptional power, and can run on only four cylinders for even better fuel economy
  • 5. Aerodynamic exterior enhancements A lowered front end and more streamlined hood leading edge reduce drag. An aluminum hood and liftgate and 18" aluminum wheels reduce vehicle weight. Refinements to the rear pillar, a small spoiler over the rear hatch and a closeout panel under the back of the vehicle help to improve airflow. Plus, the tires have the lowest rolling resistance available for a full-size SUV.
  • 6. Well-equipped standard content The Hybrid’s standard trim includes leatherappointed first and second row seats, heated front seats, Navigation radio, Rearview Camera System, Ultrasonic Rear Parking Assist and Bose premium sound system.
  • 7. Exceptional power The Vortec V8 LIVC engine with Active Fuel Management produces 332 hp and 367 lb.-ft. of torque. This impressive power allows the Hybrid to tow up to 6200/6000 lbs. and comfortably carry a payload of up to 1559/1513 lbs. for 2WD/4WD models respectively.
  • 8. The comfort and spaciousness you expect from a GMC Yukon Including seating for up to eight passengers, a 108.9 cu. ft. cargo capacity, available third row seat, available DVD Rear-Seat Entertainment System and available Bose premium speaker system.
  • 9. Exceptionally smooth ride A coil-overshock front suspension can be tuned for superior ride and handling on all road surfaces. The refined 5-link rear suspension provides better isolation, ride quality and handling.
  • 10. Extensive safety features The Yukon Hybrid is equipped with a wealth of standard safety features including frontand side-impact front air bags, head-curtain side-impact air bags, 3-point safety belts at all seating positions, StabiliTrak, Tire Pressure Monitoring and OnStar.

Power & Handling

  • World’s first two-mode hybrid propulsion system The first mode allows the vehicle to run on electric power only, engine power only, or a combination of electric and engine power at low speeds and under light loads. The revolutionary second mode enables utilization of electric assist even under heavy loads and at highway speeds.
  • Sophisticated control module Constantly monitors driving conditions to determine the amount of torque or horsepower needed at any given moment and which of the two modes it should be operating in. Transparently and seamlessly shifts between modes as needed.
  • 300-volt battery pack and two 60kW electric motors The two electric motors are primarily used at low speeds but can also help propel the vehicle at highway speeds under certain conditions. They derive their power from a compact and efficient 300-volt battery pack that is automatically recharged during driving.
  • Vortec V8 LIVC engine with Active Fuel Management The segment-exclusive Active Fuel Management system automatically shuts off four cylinders under light load conditions, transforming the V8 into an efficient V4. When full power is needed, all the cylinders are seamlessly reactivated. Also utilizes sophisticated electronic controls such as cam phasing and late-intake valve closure to further reduce fuel consumption. All-aluminum construction reduces weight for even more efficiency. 332 hp @ 5100 rpm. 367 lb.-ft. of torque @ 4100 rpm.
  • Dual-mode transmission This sophisticated technology combines a two-mode (low- and high-speed) electronic continuously variable transmission (ECVT) with four fixed gear ratios for the first time. The result is a hybrid system that can use its electric motors for both boosting output and regenerative braking in both ECVT modes and in its four fixed gears, providing a total of six operating functions. This allows the Hybrid’s electric motors to be more compact and less dependent on engine size. This two-mode system also integrates features like tow/haul mode, making them automatic. The driver no longer has to push a button when trailering on a grade.
  • Standard trailering equipment Includes a weightdistributing hitch platform and 7-wire harness.
  • Maximum towing, lbs. (2WD/4WD) 6200/6000.
  • Maximum payload, lbs. (2WD/4WD) 1559/1513.
  • Best-in-class ride and handling Yukon’s coil-over-shock front suspension can be tuned for superior ride and handling on all road surfaces. The refined 5-link rear suspension provides better isolation, ride quality and handling.
  • Premium Smooth Ride Suspension Tuned to deliver a smooth, comfortable ride with precision handling for normal usage.
  • StabiliTrak with Traction Control Monitors and compares driver steering input vs. vehicle response and makes corrections that help the driver maintain control. Proactive Roll Avoidance further reduces the risk of rollover by managing braking forces and vehicle energy during certain lateral maneuvers.
  • Autotrac 4WD All 4WD models are equipped with this active 2-speed transfer case that can automatically transfer up to 100% of engine power to the front axle when slippage occurs at the rear wheels.
  • Power rack-and-pinion steering Yukon’s power rack-andpinion steering system provides solid, precise control and steady, linear performance through corners.
  • Eaton Locking Differential Standard feature automatically locks the rear wheels together when one wheel begins to slip at low speeds, allowing the vehicle to pull away.
  • 18" aluminum wheels Yukon Hybrid’s standard 18" aluminum wheels reduce weight and help improve fuel economy. Plus, the Hybrid’s standard all-season radial tires have the lowest rolling resistance available on a full-size SUV.
