Gooday All,

Just a general question which no one has seemed to raise yet in this forum. While the base V6 sedan gets 22/32 MPG, I've noticed that the GT models are slightly lower, at 21/29. This seems hard to explain, since both models are the same weight, same engine, etc. Could the manual shift mode on the GT models be causing this? I suppose if you shift through the gears manually you might burn more gas, and its possible that whoever determines these figures is accounting for that. Any experts out there with a professional opinion?? thanks.

The difference is due to the axle ratio.

The GT has a higher ratio, causing the engine to spin at a slightly higher RPM at any given speed.

Their 29mpg highway is way off for the GT. At 75mph, I get a consistent 32mpg.

I agree! I hit 32.4mpg on average from Jersey to Boston coasting at a pleasant 70mph the whole way!

Talk about stellar mileage!

My 1.8L I4 Vibe only got 29 at it's best!

I got between 32 and 33mpg traveling about 55 miles one way, twice per day last week. Average speed was between 55 and 65.
