Martinjlm talked to this some in a few threads. I'll paraphrase-

- Most E85 sold is in the cornbelt, where the preponderance of vehicles are...trucks.

- Many local governement and fleets have requirements to have xx% of their fleeet use alternative fuels. Fleets buy lots and lots of...trucks and bland sedans (This is actually the largest driver, I believe). Might as well sell the customer what they're required to buy anyway.

- Big, engines are/were easier to modify initially- tolerances are wider, and a host of other very valid engineering reasons.

- The makers used FFVs as 'credits' towards their CAFE requriements- each alt fuel vehicle offset a low-mpg vehicle sold to the public somewhere else. They were incentivized by Washington to build FFVs in this way. Free money- might as well build it on the cheapest/easiest platform in the inventory...trucks and high-volume sedans.


Its frustrating for now, but its changing. I'm waiting for my FFV hybrid Ford Edge (and Fusion)...
