The Prius was the clear overall victor with the best average fuel economy. While it didn't win every segment of the competition, it at least finished a close second when it missed.

In those situations, the Prius's battery-boosted hybrid drive system didn't help much, forcing its small gasoline engine to do most of the work. But the Prius more than made up for it in city driving, which it won by a wide margin.
