How fast stock cars go?

The speed of stock cars varies greatly depending on the track, the car's setup, and even the weather conditions. However, here's a general idea:

* Average Speed: During a race, average speeds are typically in the range of 150-200 mph (240-320 km/h). This is an average, however, and includes times spent under caution and slower sections of the track.

* Top Speed: On certain tracks with long straightaways, stock cars can reach speeds exceeding 200 mph (320 km/h). However, this is not sustained for long periods.

It's important to note that these are approximate figures. Specific speeds will differ considerably from race to race and track to track.
