24/33 for the manual transmission are pretty good fuel economy numbers. I beat the highway numbers on a long trip by a few points if I keep it at 65 mph (a/c on). see full Pontiac G5 review

The G5 blends the mileage and power that I was looking for in a car that would do primary duty for commuting to work and back. Was looking to get 30-33 mpg. see full Pontiac G5 review
