No. Chevy created an engine that will accept alternate fuel options without compromising power and acceleration.
Go Chevy!

From a physics standpoint, E85 fuel does not have the same amount of chemical energy as regular gasoline (about 75%), so avoid using it at the strip. For the same reason, fuel economy suffers as well. The engine makes it's normal rated power when using straight gasoline.

Ethanol does have octane-increasing attributes, which allows for more advanced spark timing, as well as higher compression, but it is doubtful the ECU would be able to advance the spark or lean the fuel/air mix sufficiently to compensate for the lower chemical energy contained in E85.
