I am considering getting a '05 GTO with the automatic (or maybe a '04 if I decide I shouldn't wait on a LS2). I've noticed with the LS1 '04s the M6 mileage rating is 17/29 while the A4 is 16/21. I imagine the LS2 will be comparable.
Does anyone know why the automatic's highway mileage is so low? The LS1 in the Vette and F-bodies did not have such a drop in highway mileage when going from M6 to A4. The T/A's with M6s are 19/28 and the A4s are 18/26.
I've got a '88 GTA with the 5.7/A4 and a '01 T/A with the M6. Comparing the two, I know my next car will be an auto, but the GTOs low hwy #s are alarming considering what that engine does in the F-body.
Thanks,
Brent
