My "late model V-8" LS1 Studebaker has gotten as high as 28 mpg at 70 mph on cruise with the A/C running. Typical Highway mpg is 25-26. Late model Camaros, Firebirds and Corvettes will mostly get mid to high 20s mpg. Computer controlled EFI and overdrive has brought us a long way.

Either of my now long gone SOHC 4.6 T-Birds would crack 26 open road with the '97 often at 27+. Town was 17-19, depending on the weight of my foot at various stop lights .

Yes sir ......... that is very true .......... my 2002 Camaro SS averages well above 28 mpg on the road .......... with the a/c running ............ coming back to North Carolina from the Skyline Drive cruise (with the tops off and not using the a/c) it averaged 30.3 mpg ............... at 70 mph in 6th gear, the LS1 is loafing along at 1600 rpm .......... and this beast will average over 18 mpg around town (if you keep your foot out of it)



There is indeed a lot to say for computer controlled EFI and 0.50:1 overdrive ratios
