Chevrolet Tahoe Hybrid

Mention hybrid, and most people think of fuel misers, such as the 40-to-50-mpg Toyota Prius. But a hybrid pow-ertrain can save fuel in vehicles of any size, as demonstrated by this Chevrolet Tahoe, which represents the first example (along with the GMC Yukon and 2009 Cadillac Escalade) of hybrid technology applied to a large SUV. As such, it gets a big-time fuel-economy bump, but as a 5840-pound vehicle, it isn't—and can't be—a fuel miser by anyone's definition.
