Under the Hood

The Yukon Hybrid uses a two-mode hybrid system. The system augments the SUV's V-8 engine with two electric motors, both powered by a 300-volt battery pack. A cylinder-deactivation system cuts power to four of the eight cylinders during low-stress situations, such as downhill coasting, and regenerative braking is used to recharge the battery. When properly equipped, the rear-wheel-drive Yukon Hybrid can tow 6,200 pounds, and the four-wheel-drive version can tow 6,000 pounds. Mechanical features include:

332-horsepower, 6.0-liter V-8 with cylinder deactivation that generates 367 pounds-feet of torque
Two-mode continuous electric ratio hybrid transmission with four fixed gears
Rear- or four-wheel drive
Electrically driven power steering
Electrically driven air conditioning cools cabin even with the engine off
