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

Since my driving is about 50-50 city and highway, I average about 20-21 mpg, using premium fuel. All highway is 29-30mpg and all city is 14-15mpg. see full Mercedes-Benz S-Class review
2007 0 While on long trips at 70-80mph I average 32mpg around town it never goes better than 24mpg. Easy on the pedal sure shows results but fully loaded the thing shifts like a two door sports. see full Mercedes-Benz S-Class review
