What Our Members Are Saying about the Real Gas Mileage of the Porsche Cayman

Porsche Cayman Real Gas Mileage: Pros
YearBody/PowertrainComment
2008 2dr Hatch 295-horsepower 3.4L H6
6-speed manual RWD		 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
2008 2dr Hatch 295-horsepower 3.4L H6
6-speed manual RWD		 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
Porsche Cayman Real Gas Mileage: Cons
YearBody/PowertrainComment
2007 2dr Hatch 295-horsepower 3.4L H6
6-speed manual RWD		 It sucks if you are driving the car correctly. On the slab I can see 26 mpg. see full Porsche Cayman review
