Is FlexPower a new name for FlexFuel or AFM?

3900 in the Lucerne should give it a decent bump. I bet that engine can be made to run real quiet.

Nahh, just the Brazilian name. I just have "E85" in my spreadsheet.

hopefully that comes in '10 for kappa, at least. whether it's for the 2.2 or 2.4 i don't think it'd matter much if a turbo 1.4L comes standard for the deltas
