Lotus Elise/Exige

A Lotus? Third place on a list of fuel-efficient cars? You bet, and you can thank the premium-fuel sipping Toyota-sourced engine for its high ranking here. The Lotus Elise is not for everyone. Its light weight makes it fun to drive, but the Elise is also tiny, noisy and cramped. Yet it's a giant killer, and can whip much more expensive and powerful cars around a track, and nail them on fuel economy, too.
