NTT IndyCar and Indy NXT Series: America’s Premier Open-Wheel Racing
IndyCar’s Drive Toward the Future
The NTT IndyCar Series represents the pinnacle of open-wheel racing in North America, boasting a legacy that dates back to the early 20th century. Governed by INDYCAR, the series is home to some of the fastest and most technologically advanced race cars, competing on a mix of road courses, street circuits, and high-speed ovals. At the heart of the championship is the iconic Indianapolis 500, held annually at the Indianapolis Motor Speedway, which remains one of the most prestigious motorsports events worldwide. The series attracts top drivers from around the globe, many of whom have backgrounds in Formula One, endurance racing, and other high-level competitions.
A key component of the IndyCar Series is its dedication to innovation while maintaining a focus on driver skill and close competition. The current Dallara IR-18 chassis, in use since 2018, provides a level playing field, while the twin-turbocharged 2.2-liter V6 engines supplied by Honda and Chevrolet add a distinctive manufacturer rivalry. The competition is fierce, with teams balancing speed, aerodynamics, and strategy to gain an edge on the track. The combination of multiple circuit types, push-to-pass technology for overtaking, and minimal driver aids ensures thrilling, unpredictable races that demand maximum performance from both man and machine.
The Indy NXT Series, formerly known as Indy Lights, serves as the official development platform for up-and-coming open-wheel talent aiming to reach the NTT IndyCar Series. Operated by INDYCAR, this feeder series has long been the stepping stone for future stars, including current IndyCar champions and Indianapolis 500 winners. The series features the Dallara IL-15 chassis powered by a turbocharged 2.0-liter engine, providing drivers with experience in high-speed racing, pit stops, and racecraft essential for transitioning to the top-tier championship. Indy NXT races often support IndyCar events, allowing young drivers to showcase their abilities in front of major teams and sponsors.
One of the most significant changes to the NTT IndyCar Series in 2024 is the long-anticipated introduction of the hybrid power unit, marking a major shift toward sustainability and technological evolution. Developed in collaboration with Honda Performance Development (HPD) and Chevrolet, the new hybrid system combines the existing 2.2-liter twin-turbo V6 with an energy recovery system (ERS) that captures and redeploys energy, enhancing acceleration and efficiency. This move aligns IndyCar with global motorsport trends while maintaining the series’ signature high-speed, competitive racing. Additionally, the hybrid system will eliminate the need for an external starter, allowing stalled cars to restart independently, reducing race stoppages and improving safety.
While the integration of hybrid technology represents a move toward sustainability and efficiency, IndyCar remains committed to its traditional strengths—high speeds, daring overtakes, and intense competition. Teams and drivers must adapt to the new powertrain dynamics, which introduce energy management as a strategic factor. The hybrid system is expected to enhance overtaking opportunities and improve fuel economy, making race strategies even more complex and engaging for teams and fans alike.
With the IndyCar Series embracing hybrid technology and Indy NXT continuing to develop future stars, both series remain vital to the fabric of American open-wheel racing. As the sport evolves, IndyCar maintains its unique identity—offering a perfect balance of historical prestige and modern innovation—cementing its status as one of the most exciting motorsport championships in the world.
