For review. CAFE stands for Corporate Average Fuel Economy.
All GM needs to do is make every Zeta engine FlexFuel. Forget hybrid, forget hydrogen, forget fairy dust. It would cost an extra $100 per car to make them FlexFuel. CERTAINLY cheaper than spending a huge amount of money to fund development of the platform only to throw it in the dustbin. The idea that GM cannot make the ZETA up to CAFE standards is complete and utter BS beyond any shadow of any doubt. To those of you who celebrate the Zeta demise, you are shortsighted, unimaginative, and are clearly a danger to General Motors. Furthermore... unless GM is planning on having Zeta around for a W-body like amount of time, there would be two to three revisions of the platform completed by the time the 35mpg AVERAGE comes into effect. Do you think Ford was pumping out FlexFuel Tauruses and Sables in 1999 out out of the kindness of their dear sweet hearts? No, it was to raise their CAFE on the cheap.
GM has LOTS of CAFE credits due to their production of FlexFuel vehicles.
Additionally
The new CAFE legislation has retained the extra credit provision for FlexFuel.
In short, any argument using CAFE as a reason for canceling ANY Zeta vehicle is a complete Red Herring designed to deflect the truth about the internal political struggles inside of GM.
Edit: A 19mpg EPA combined FlexFuel Zeta <this assumes HF3.6 and similar weight to '07 CTS> would be rated at 40mpg.
