That the 2007 IndyCar Series will be run using 100 percent ethanol is not news, so we won't repeat what we've told you before (see the links below if you missed things). What we will bring up here, late on a Friday, is that tomorrow is finally the day that the 3.5-liter Honda Indy V-8 engine start using pure ethanol in competition. The race is the XM Satellite Radio Indy 300 on the Homestead-Miami Speedway in Florida. E100 was tested in the cars earlier this year.
While Honda's latest racing announcement is a positivist preview for the 2007 racing season, including F1, IndyCar, SuperGT, etc. What's interesting to us are the E100-ready engine announcements.
