No, on the Chrysler products that offer flex fuel when running on E85 there is a 25% loss in fuel economy.
Yes you can, infact you will get better Fuel mileage than E85.
less wind resistance, better fuel mileage
Less weight = better fuel mileage.
Better fuel mileage and cleaner emissions.
I would say the best fuel effecient cars would be the flex fuel cars.They get great mileage and cheap to fill up.
RAV4 vehicles feature off roading, high fuel mileage, and Flex fuel, which allows you to use up to 85% ethanol in them. They also have a spacious interior.
The less weight, the better the fuel mileage.
So that the cars not make enviroment worse
Most car companies are going in the direction of creating fuel efficient cars and trucks, but you might want to contact Toyota at their website Toyota.com and ask them when they will start production on flex fuel cars. GM currently has vehicles that are flex fuel so go to Chevy.com or GMC.com and look at what flex vehicles are out on the road currently.
Less weight equals better fuel mileage. Crampled?
Newer cars are geared towards being more fuel efficient than older cars. Cars made in 2012, depending on engine size, will likely get much better gas mileage than your 1993 Buick. These older cars were geared more towards comfort and power and less towards improved gas mileage.
If you are referring to E85, from my experience using E85 actually lowers the fuel economy.
