You get a little more cooling from the E85, but it is really a very small difference. Normally E10 is available on the same pump with the E85, so blending it really is no big deal. There are a few other advantages to E70 as well, like it starts quicker on a cool day, and if it is a street car, you get about 10% more range from a tank of gas.

The group of people that chose 85% as the blend of ethanol in E85 fuel had the intent of replacing as much gasoline as possible with ethanol. After all, the intent of this fuel was to replace foreign oil, and clean up the environment, not fuel our tire burning machines. In fact it is a bit of an ironic deal that we are using this "clean renewable fuel" in our cars without catalytic converters, and our large overlap cams spewing out unburnt hydrocarbons out into the environment. If you took into account other factors, like cold starts, fuel range etc. E70 would have been a far better choice.
