10 Surprisingly Fuel-efficient Sports Cars


Mercedes-Benz SLK250

The Mercedes-Benz SLK250 looks the luxury sports car part and plays it well, too. With just a 1.8-liter turbocharged 4-cylinder engine, the SLK250 produces 201-horsepower and 229 ft-lb of torque -- which Mercedes-Benz likes to remind consumers is more than the previous V-6-equipped model. With the seven-speed automatic transmission, this $44,000 sports car churns out 23 miles per gallon (9.8 kilometers per liter) in the city and 31 (13.2 kilometers per liter) on the highway [source: Archer]. Oh, and it comes in a hardtop convertible model as well.
