NASCAR introduced a new rule Tuesday that will award one point to the team and driver with the fastest single lap in each race. The “Xfinity Fastest Lap” was added as part of a contract renewal between NASCAR and Xfinity. The new deal awards a point for the fastest lap in all three of NASCAR’s national series, continues Xfinity’s role as entitlement sponsor of the second-tier series through 2025 and includes a multiyear agreement for Xfinity to extend its premium partnership with the Cup Series.
