A sprint car can still run alot of laps even today, look at the little 500 for an example, 500 laps with 2 pitstops means you need to run up to 200 laps nonstop. Can be done with bigger tanks, harder tires etc.
when we ran 100 laps on a half mile in usac there where 305 ci. Engines! And we raced 100 mile midgets races! With 15 gallon tanks! The little 500 is a 125 mile race! And not on the gas very long!!!!!!!!!!! With 410ci. Engines today your lucky to run 20 miles on a half!!!!!!!!!
