What Is the Top Speed of NASCAR Cars?

The top speed for most NASCAR cars is about 200 mph. NASCAR frequently tweaks the rules and regulations to adjust to the current conditions, which make the top speeds attained in each race slightly different. In January 2013, the fastest car at Daytona Beach reached over 206 mph.

Generally, NASCAR cars reach their highest speeds during qualifying laps. When racing on a crowded track, the average speed of each car diminishes slightly. However, through the process of drafting, in which a car breaks the air resistance for the car behind it, drivers sometimes meet or exceed the 200 mph barrier during races.
