One of the stars in the fuel-efficient spotlight has got to be the Lotus Elise. Aside from being one the best looking sports cars on the road, it also boasts some amazing fuel efficiency numbers. With a relatively small 1.6-liter engine and just 134-horsepower, the Lotus Elise may not sound like much of a sports car. But because of its low weight and supreme aerodynamics, the Elise can sprint from 0 to 60 miles per hour (0 to 96.6 kilometers per hour) in just 6 seconds [source: Seitz]. With its six-speed manual transmission, you can expect to get 34 miles per gallon (14.5 kilometers per liter) in the city and (according to Lotus) a whopping 56 miles per gallon (23.8 kilometers per liter) on the highway.
