The 2009 GMC Yukon Hybrid has been described as "impressive", "stunning" and "magnificent" by both reviewers and owners. They're not talking about the Yukon Hybrid's performance, amenities or looks, although all are average or above. They're talking, instead, about the fuel economy figures they see with this hefty hybrid. Both of GM's 2009 full-size SUV hybrid models, Yukon and Tahoe, feature the innovative, 2-mode hybrid system, introduced in 2008. Combined with GM's active fuel management technology and a unique late-intake valve opening system, the computer-modulated 2-mode electronic variable transmission (EVT) technology translates into real savings at the pump. Since its ‘08 debut, the GMC Yukon Hybrid has boosted gas mileage nearly 30% compared with non-hybrid Yukon models. EPA estimates of 21 mpg/city and 22 mpg/hwy for the 2WD Yukon Hybrid and 20/20 for the 4WD model are, indeed, impressive. A comprehensive list of standard amenities comes with the '09 GMC Yukon Hybrid, including 8 passenger seating, leather 6-way adjustable front power seats and a sound-system-integrated GPS with back-up camera. In addition, the Yukon Hybrid features 6000- to 6200-pounds of towing capacity, anti-lock brakes and stability control. With its 2-mode EVT system, a bit of aerodynamic tweaking and a 350lb-plus weight reduction in the wheels, body and cabin, yet still weighing in at nearly 5300-pounds, the 2009 GMC Yukon Hybrid is both big and "green". Starting at $50,945 for the 2WD '09 Yukon Hybrid, and some $2,810 more for the 4WD, big and "green" is also pricy.
