Hyundai may not be the first car company you think of when discussing sports cars, but it does know a thing or two about the subject -- not to mention fuel economy. The Genesis Coupe puts out 348-horsepower from a 3.8-liter V-6 that moves from 0 to 60 miles per hour (0 to 96.6 kilometers per hour) in just 5.2 seconds. All that, and this powerhouse is still able to achieve 18 miles per gallon (7.7 kilometers per liter) in the city and 28 miles per gallon (11.9 kilometers per liter) on the highway. If you want to sacrifice a little speed, you can go with the 274-horsepower version and get 20 miles per gallon (8.5 kilometers per liter) in the city and 30 miles per gallon (12.8 kilometers per liter) on the highway. Either way, you really can't go wrong.
