Through the first 13 races with NASCAR’s new aerodynamic package, there have been 41 accidents involving a total of 76 cars, according to the boxscores. Through those same 13 races in 2018, there were 40 accidents, but they involved a total of 103 cars — a big difference.
It is still a small sample size, but the numbers indicate that there have been fewer of those smoky, sometimes fiery, multi-car wrecks. There have been only four races this year in which there were more accidents than the same race a year ago.
In fact, the overall crash numbers for this year are skewed by the 11 accidents that involved 19 cars at the Coca-Cola 600 on May 26. There were just five accidents involving eight cars there in 2018. Bristol, however, was down, from 25 wrecked cars total in 2018 to 16 this year.
