Verstappen has won all three previous sprint races this season and has won the main race in Austin the last three years. But he hasn't won this season since the Spanish Grand Prix on June 23 and has earned just three podium finishes in that span. Verstappen at times has described his once dominant car as “undrivable” and a “monster.”

Max Verstappen remains in the driving seat but he has not won a Grand Prix since June—a run of eight events. Lando Norris has trimmed Verstappen's points advantage from 84 at its peak to 52. The sudden end to Verstappen’s winning streak, and the possibility of a title battle, has aided ticket sales at Circuit of the Americas in Austin, Texas.

What does Lando Norris have to do at the U.S. Grand Prix and the final five races to beat Max Verstappen to the F1 title?
