Today’s NASCAR Sprint Cup series features 36 different races on 22 diverse race tracks. 34 of those races feature all left turns on ovals or D shaped race paths, and two of the races are held on road courses.
In the start, stock car racing was exactly what it sounds like. Drivers just bought brand new cars from suppliers and went racing. The National Association for Stock Car Auto Racing (NASCAR), organized in 1947, created a standardized set of directions for stock car racing and established an arrangement for choosing a national champion based on performance and presentation at races all across the country.
The original races were run on dirt tracks that got rutted and jerky. The original cars were not tough enough for this type of exploitation, so NASCAR began allowing modifications to the stock cars to upsurge their resilience.
Today, NASCAR race cars have very little in common with road cars. Almost every feature of a NASCAR car is handmade. The bodies are constructed from flat sheet metal, the engines are assembled from an unadorned block and the frame is constructed from steel tubing.
