But it does get better mileage and fuel economy. 27hwy which is very good in a massive car like the CTS, especially under the new EPA ratings.
. The new Vette no longer gets AFM, and under the new EPA standards, it has 26mpg, which is an improvement, the old way had it rated at 27 so....
I also think there may have been a slight misconception, here...E85 actually worsens fuel economy, it can
provide more performance, but at the price of fuel economy...
i.e. Chevy Impala
3.9L V6 VVT and AFM: 18/28 mpg
same engine running E85: 13/20 mpg
it's only major selling point at this time is it burns clean.
That coupled (hopefully) with it being a fair bit cheaper then petrol... but this is still early stages for E85.. if the car companies are serious about using it they'll get their R & D fully on the case when it comes to MPG.
The only problem i can see from this then is getting enough fuel in to the cylinders on high power cars... could cause detonation problems.
