2008 GMC Yukon Hybrid

Two-wheel-drive Tahoe and Yukon Hybrid models deliver EPA fuel economy of 21 mpg in the city, a 50-percent improvement over their 5.3L gasoline-only siblings and comparable to the city fuel economy of the much-smaller 2008 2.4L-equipped Toyota Camry sedan, according to figures obtained from www.fueleconomy.gov. EPA highway fuel economy is 22 mpg. The fuel savings is impressive on 4WD models, too, with the Tahoe and Yukon Hybrids rated at 20 mpg in both city and highway driving. This gives the Tahoe and Yukon Hybrids a driving range of about 525 miles per tank of fuel, or enough for a trip from San Diego to San Francisco.

Making this possible is GM's all-new, advanced electrically variable transmission and 300-volt nickel-metal hydride Energy Storage System (ESS), which work in concert with the standard 6.0L V-8 gasoline engine with Active Fuel Management (AFM) and late-intake valve closing (LIVC) technology. GM's new 2-Mode Hybrid system enables the Tahoe and Yukon to launch and drive up to 30 mph on electricity alone and allows the 6.0L V-8 engine to operate in its more economical V-4 mode for longer periods. The Tahoe and Yukon Hybrids also save fuel with aerodynamic aids and reduced-mass components.

Along with exceptional fuel economy, the Tahoe and Yukon Hybrids deliver full-size SUV capability - up to 6,200 pounds (2,812 kg) of towing capacity (2WD) and 6,000 pounds (2,722 kg) on 4WD models; 12,000 pounds (5,443 kg) GCWR and eight-passenger seating capacity.

From subtle interior touches to functional exterior aerodynamic details, the Tahoe and Yukon Hybrid stand apart from the crowd. Once in the driver's seat it is instantly clear that these vehicles are special -- from the unique gauge clusters with distinctive badging to the special tachometer. Even the stylish thin-profile seats, designed to reduce mass for improved fuel savings, also provide a side benefit of increased second-row leg room.

These generously equipped, full-size SUVs include heated leather-appointed front bucket seats and leather-appointed second-row bench; driver and passenger power-adjustable seats; navigation radio with rearview camera system; a Bose premium sound system; XM Satellite Radio and the OnStar safety and security system. Other standard features include StabiliTrak electronic stability control; tire pressure monitoring system; a tire inflator kit (in lieu of a spare tire); cruise control; trailering receiver/equipment; two-speed transfer case (4WD); locking differential; 18-inch lightweight polished aluminum wheels and assist steps.

On the outside, form follows function with numerous aerodynamic features such as a lowered air dam, shaped running boards and special rear-end treatments. They enhance the vehicles' overall appearance and contribute to their 0.34 drag coefficient. Noise-reduction measures include a new exhaust system and resonator; low-rolling resistance tires; additional engine intake induction tuning; an electrically driven, 300-volt air conditioning compressor and 42-volt variable-assist power steering; and tuning to the Energy Storage System cooling system internal fan.
