Starting in 2020, IndyCar, like many other motorsport series, began using cockpit protection. Unlike the Halo system employed in almost all European racing series, IndyCar, in collaboration with Red Bull Technologies, developed its own variant of cockpit protection. This innovative piece of technology, called the aeroscreen, was successfully introduced nearly five years after Justin Wilson's death.
While the Halo system primarily protects drivers from flying debris in specific areas, the aeroscreen offers protection to many other areas in and around the cockpit that are completely exposed with the Halo system. Since the introduction of the aeroscreen, IndyCar drivers have been better protected in their cockpits than ever before.In 2024, the IndyCar Series introduced a change to its engines. Midway through the season, a hybrid component was added alongside the traditional internal combustion engines. This provides the average 700-horsepower engines with an additional 150 horsepower at certain points during a lap.
After 5.5 years of sole ownership of the IndyCar Series, Penske Entertainment has sold one-third of its shares to Fox Corporation, the parent company of FOX Sports. As part of this acquisition, FOX gains partial ownership of the IndyCar Series the Indianapolis Motor Speedway, and several IndyCar events promoted by Penske Entertainment. This investment is expected to help IndyCar with the promotion of the series.
