Our friends over at Edmonds.com have done a rather interesting comparison of fuel economy in 19 sports cars available in 2011.

Monthly fuel costs ranged from $330/month for the Corvette ZR1/BMW M3 on one end, and $165/month for the MINI Cooper. But the fuel-sipping Cooper wasn’t the only MINI at the top of the Edmonds list. The Cooper, Cooper Convertible, Cooper S and Cooper S JCW took the top four spots. Looking at the numbers, on fuel alone a MINI is about half the operating cost of an M3. Sure, the M3 has a lot more horsepower and panache, but with gas creeping toward $5/gallon there’s a lot to be said for thrifty thrills. Check out their full analysis here.
