IndyCar – Sonsio Grand Prix 2026

The Sonsio Grand Prix ignites Indianapolis Motor Speedway's Month of May with a 2.439-mile road course duel, the sixth such INDYCAR event blending oval heritage with twisty precision. This 14-turn layout—featuring the iconic Bowl and infield esses—challenges hybrids' traction out of Turn 4's stadium roar, evoking Road Atlanta's flow but amplified by 250,000-strong crowds. Debuting in 2014 as the Grand Prix, it shifted from streets to speedway, birthing moments like Simon Pagenaud's 2016 triumph and Takuma Sato's hybrid preview. As May 9's prelude to the 500, it tests setups for the oval onslaught, where energy strategies add tactical depth to its 85-lap chess match. IMS's hallowed grounds, kissed by kissing the bricks, infuse every lap with lore—from A.J. Foyt's eras to modern hybrids' dawn. This race transcends circuits; it's a narrative bridge, where international flair meets Hoosier heart, forging undercard legends en route to racing's pinnacle, all under the Speedway's timeless spires.
