    Finally, those who enjoy motorsports but find series like NASCAR increasingly irrelevant have something to cheer about. But let us see if Audi remains the exception or if some of its key competition actually takes the Challenge seriously. And nice try GM, but ethanol does not cut it. How about racing the Volt against the Toyota Prius...lol

    The article says,"GM has been a major proponent of E85, which is made up of 85 percent ethanol and 15 percent alcohol."

    1. Ethanol is an alcohol.
    2. Isn't "E85" 85% ethanol and 15% gasoline?

    Couple of quick points regarding the use of methanol for INDY race cars. The switch to methanol occured over 30 years ago because methanol is a safer fuel than gasoline. Harder to ignite a fire and buts with one-eigtht the heat. INDY has now switched to ethanol because the ethanol industry is paying to subsidize the fuel. Yes, methanol is toxic, just one swallow can be fatal versus two swallows for gasoline. We're not aware of any race car drivers looking to sip their fuels. And methanol does not readily contaminate groundwater when there is a spill. That's just plain false. Methanol and ethanol are both readily biodegradable, with a half-life in groundwater of one to seven days, as compared with benzene -- a gasoline component -- with a half-life measured in the hundreds of days.
