2018 2nd GRID World Championship
The second season of the GRID Ranking again saw IndyCar racer Sebastien Bourdais lead the first weekend of the GRID Ranking, but it didn't last long as NASCAR saw three drivers dominate most of the season. Kyle Busch, Kevin Harvick, and the 2017 GRID Ranking Champion Martin Truex, Jr. all exchanged the lead. However, Marc Marquez at MotoGP had several dominating races, earning the lead with a few weeks left. Kyle Busch failed to finish third or better at the NASCAR season finale, coming up short of passing Marquez by 0.01 point.
