It is better than I expected. I average roughly 23 miles with city and highway commuting on days I choose to take it to the office. On trips I can get 26 mpg, not stellar but not awful. see full Porsche Cayman review

Fuel economy is reasonable relative to the car's performance - 20 mpg, plus or minus a couple depending on the balance of city versus highway driving. see full Porsche Cayman review
