The GMC Yukon Hybrid is a gasoline-electric version of the GMC Yukon full size sport utility vehicle. The GMC Yukon, which has always been nearly identical to the Chevy Tahoe sport utility vehicle, was introduced by General Motors in 1992; the Tahoe followed in 1995. The GMC Yukon is a front-engine vehicle that has been available in both rear-wheel-drive and all-wheel-drive configurations, both of which are available for the Yukon Hybrid. The Chevy Tahoe Hybrid and GMC Yukon Hybrid were introduced in the fall of 2007 as 2008 model year vehicles, and were discontinued for the 2014 model year.
The GMC Yukon Hybrid’s drivetrain is based on a dual displacement 3-liter/6-liter V8 gasoline engine that is paired to two 60 kW continuous electric motors that are housed in the transmission. A continuously variable drive system handles light loads, while a four-speed fixed gear unit takes over heavier driving conditions. The battery is a 300-volt nickel-metal hydride unit. Combined output of the GMC Yukon Hybrid’s drivetrain is 379 horsepower. Thanks to the battery’s size and capacity, the Yukon Hybrid can travel for short distances at up to 25 miles per hour on electric power alone, but the vehicle most commonly uses its two-mode hybrid system to travel on a combination of gasoline and electric power. The battery is charged via the electric motors’ operation from the gasoline engine, or through the vehicle’s regenerative braking system, which recaptures the kinetic energy that would be lost as the vehicle brakes to a stop, and instead feeds that energy back to the battery. To reduce weight, which further helps fuel economy, The GMC Yukon Hybrid earned Environmental Protection Agency ratings of 21 miles per gallon city and 22 miles per gallon highway for the rear-wheel-drive version. Though the Yukon Hybrid boasts fuel economy ratings about 50 percent better than its gasoline sibling, the towing and cargo capacity in the GMC Yukon Hybrid are similar to the ratings for the traditional gasoline version of the Yukon.
Visually, the GMC Yukon Hybrid is identical to the regular version of the Yukon. The 2013 model year of the Yukon Hybrid is available only in one trim level, and the only options are a sunroof and a DVD entertainment system for the rear seats. The Yukon Hybrid offers space for eight occupants, thanks to its standard third row seat. Other standard equipment includes lightweight 18-inch alloy wheels, tri-zone automatic climate control, tinted windows, rear park assist, a rearview camera, a trip computer and hybrid information system display, Bluetooth wireless integration, General Motors’ OnStar communications and emergency system, keyless remote ignition, an auto-dimming rearview mirrow, power-folding heated side mirrors with integrated turn signals, leather upholstery, power front seats, navigation, real-time traffic information, and a nine-speaker Bose audio system with USB input and satellite radio. The GMC Yukon Hybrid also comes equipped with standard safety equipment such as front seat side airbags, full-length side curtain airbags, anti-lock disc brakes, traction control, StabiliTrak stability control, and an automatic crash response system integrated with OnStar.
