4. NASCAR
Even though there are other world-scale car racing events such as WRC, NASCAR is still arguably the most popular one in America.
Nowadays, there are many classes of NASCAR which held in another part of the world as well, such as the Whelen Euro Series.
The Red Bull Racing Team competed in NASCAR from 2006 until 2011. Throughout its entire races (286 in total), the team won only two of them. Perhaps that was the reason why the company decided to sell the team to BK Racing.
All NASCAR vehicles are equipped with 358-cubic-inch (5.9-liter) V-8 engine. Based on NASCAR regulation in 2016, each car’s base package includes a 3.5-inch spoiler, a 0.25-inch front leading splitter edge, and a 33-inch wide radiator pan.
