After winning Sunday’s New Hampshire 301, Matt Kenseth’s No. 20 Toyota failed post-race inspection at New Hampshire Motor Speedway.
According to NASCAR, Kenseth’s car failed the laser inspection station and will be taken to the NASCAR R&D Center in Concord, North Carolina for further inspection. Runner-up finisher Tony Stewart’s car passed the LIS platform after the race and will also be taken to the R&D center for evaluation, which is standard protocol.
Sunday’s win was Kenseth’s second victory of the season and third career win at New Hampshire.
Typically, the penalty for failing LIS has been 15 points and a fine for the crew chief. Kasey Kahne’s No. 5 failed after the Dover race, and Kyle Larson’s No. 42 was penalized after last month’s race at Michigan.
