America's definition of the SUV has changed over the past decade.
Once upon a time, they were big, trucklike gas hogs that could go anywhere and do almost anything. Today, however, they have evolved into smaller, more carlike vehicles that go easier on gas, and consequently are better for the environment and softer on the wallet. Unfortunately, they are also slightly less capable.
Regardless, the masses still refer to these new vehicles as SUVs, and they are one of the fastest-growing vehicle segments on the market.
