Just drove from Vegas to Kingman and back, scored 54 average for the round trip. Highway driving is still impressive in the C vs standard cars but it definately shines much more in city driving. Still, 54 mpg - I'll take it! What other car can you say hmmm... I have 3 galons of gas left in the tank and I have to get from Kingman back to Vegas (105-110 miles) I'll only need 1.5 - 2 of the galons I have left, I'm good, let's roll! Hahaha
