Any notable differences between the 08 RX8 compared to the 09 one?
Gas mileage might even be worse, since the 09's have a 4.777 rear in the back and the 08's have a 4.444. It all depends on the gear ratios for the transmission, but I haven't looked at them.
So it looks like highway mileage should be unaffected based on the gear ratios. The big difference it first gear. All the other gears are relatively the same, with the 2009 being shorter by alittle bit in each gear. In town mileage may suffer though.
1st Gear
2008 3.760*4.444=16.709
2009 3.815*4.777=18.224
6th Gear
2008 0.843*4.444=3.746
2009 0.787*4.777=3.759
