The Roval is Just a Really Fast Road Course

This weekend marks the very first time NASCAR has run a race on the Charlotte Roval: a combination of the oval track we run in May with select portions of the road course in the infield. It’s a unique situation because, unlike most road courses, this one is contained. Fans will be able to see the entire course.

Do Tires Affect Gas Mileage?

When winning means a few hundredths of a second, nothing is too small to be ignored. I’ve talked a lot about energy and the importance of using it as efficiently as possible in racing. Gasoline provides a certain amount of stored (a.k.a. potential) energy.
