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.

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. Everyone gets the same amount of energy. Winning lies…
