2008 4dr Sedan 110-horsepower 1.6L I4
5-speed manual FWD
From a 17mpg average Chevy truck to NEVER getting less than 29mpg city, need I say more? Well okay, how about 37mpg on a freeway run. I have only got 13000 miles on the vehicle, and can imagine the fuel economy will improve still more. see full Kia Rio review

An AWD V8 body on frame SUV/truck like the Rainier will be a gas pig. Mid to high teens are all you should expect. The benefit of poor gas mileage is strong towing performance. see full Buick Rainier review
