Think Alexander Rossi, Romain Grosjean, Marcus Ericsson and Takuma Sato. Rinus 'VeeKay' van Kalmthout is currently the only Dutchman in the class. Earlier, Robert Doornbos and Arie Luyendyk also drove in the IndyCar Series. Luyendyk is to date the most successful Dutchman in the American class. He won the Indy 500 twice.
Since 2012, IndyCar teams have driven a Honda or Chevrolet V6 engine with a twin-turbocharger. The engines produce between 550 and 750 horsepower depending on the level of boost used and no inter-cooling systems. The engines are limited to 12,000 rpm and weigh 112 kilograms. From 2024, IndyCar will use hybrid engines.
Dallara provides the chassis to the teams, this chassis is currently in use since 2018. The aero package is still updated every now and then, for example, the championship has been running since 2020 with an aeroscreen manufactured by Red Bull Advanced Technologies. The aero packages also differ per circuit. There is a package for very low downforce ovals, a package for short ovals that is actually only used on Gateway and a high downforce package for the road and street circuits. Firestone has been supplying the tires since 1996, although it still had competition from Goodyear until 1999.
The points distribution of the IndyCar Series is different from what is used in Formula 1. The race winner receives 50 points, number two 40 and three 35. Number four receives 32 points and for each place lower, two points are deducted from that total to place. ten. From that position, each driver receives one point less for a place lower finish. From the 25th finish position, everyone receives five points. During the Indy 500, double points are awarded.
