DC is adding three more models to their ethanol-capable category. Two of these will be Jeeps - the Commander and Grand Cherokee. The Dodge Dakota will also get the option.

DC has committed to offering at least one quarter of their fleet to the general public with the flex-fuel option by 2008.

Chrysler offers several other models with engines capable of burning ethanol, including the Dodge Caravan/Chrysler Town & Country minivans, Dodge Stratus, Chrysler Sebring, Dodge Durango and Dodge Ram pickup.

Ethanol, also known as E85, is a fuel usually made from corn that’s touted as a renewable source of energy and an alternative to petroleum-based gasoline. Flex-fuel engines can run on either E85 or gasoline.
