I was VERY interested in the Sonic RS and anticipated that model even before it was released. I went to the Detroit Auto Show to see it, but sadly couldn't sit inside of it. I really like almost everything about it except the transmission shift ratios and hence the gas mileage. The shift points are much sooner and the final drive ratio is much lower so it revs much higher at highway speeds. So it only gets 34 MPG vs. 40 MPG on LTZ. I wish they offered option for RS appearance and regular transmission, but they don't.
