I was actually watching NASCAR the other day (my once annual viewing) and apparently these new "Cars of Tomorrow" that they are racing are now using UNLEADED fuel. They were talking about the heat in the car, when I was watching, and how UNLEADED creates a higher exhaust heat so the drivers were starting to complain that it was getting too hot and they were showing off the little peltier cooling boxes that they had hooked up to the drivers helmets to help cool them down during the race.
