Quick Questions Regarding Cobalt XFE

How Much Will The Price Go Up With That Little Badge On The Trunk?

How Bad Will This Hurt The "Pre-March 17" '08 Cobalts Resale?


Just the first thoughts that came to mind.:D

Not that extra MPG is a bad thing. It should do quite well from a marketing stand point, as long as GM makes sure people know what the XFE is/stands for. Kinda like Fords "green leaf" for the Flex Fuel vehicles, not many people knew what that was.IMO

What about those folks with onlly a RIGHT LEG ???? We have to suffer with sub par feul mileage and the 4 spd auto........
Ha! I was thinking the same thing. I guess I should be happy that my "old" '08 Cobalt will get the same mileage as the newer '08 Cobalts with automatics.:rolleyes:

Why badge it, the extra cost of the badge is needless expense.

Also, since it's on the 5 speeds the "take" rate is going to be low, I wonder if the 6 speed auto from the EP's fits in the Delta cars? Adding the 6 speed auto could help.

unless they changed gearing I want to say that this is tied to the VVT being added to the 2.2L.

Now they should add GDI to the engine for even better MPG maybe as much as 38MPG highway to blow away the civics. :bounce:

This is 36MPG SAE which I believe would be about 46MPG CAFE.

I can't find anything that states it is a different engine, so I am assuming this is all transmission-related. Man...if they can get that out of the non-VVT 2.2L, I am very eager to see what the 2009's rating ends up being!

I want to know more about this...if it is done with 'engine calibration', or possibly they are starting to put the new vvt 2.2 in it...it should help the automatic equiped Cobalts also....a little more information/confirmation on this topic by GM would be very helpful.
