Savings: 7.6% It says "hybrid" right in the name, but that 21.5 miles per gallon fuel efficiency can't be right, can it? Absolutely it can. This General Motors ( GM) beast's hybrid engine isn't there to make the Yukon Denali a fuel sipper. It exists solely to minimize the damage wrought by its 6.0-liter V8 engine. Nobody's coming to this party to hug trees. They're here for the eight-passenger capacity, four-wheel drive, navigation, Bluetooth, satellite radio, 6,000-pound towing capacity and 109 cubic feet of maximum cargo space. Still, the hybrid version only gets drivers a scant 5 mpg more than they'd get in a regular Yukon while charging nearly $20,000 more for the privilege. This boat and its sister, the Chevy Tahoe, have a fairly limited market to begin with, but it's likely going to take more than an 8% discount to woo new fans.
