Honda tests next-generation INDYCAR internal combustion engine; complete hybrid unit in 2024

Honda donated the next-generation 2.4-liter internal combustion component (4and) NTT INDYCAR SERIES hybrid power unit on track debut at the Indianapolis Motor Speedway. With six-time INDYCAR SERIES champion Scott Dixon driving the Honda test chassis operated by Chip Ganassi Racing, the new internal combustion engine (ICE) was put through its paces on a modified version of the 13-speed Indianapolis. bends and 2.6 miles. Layout of the Motor Speedway road course which hosts two races each year on the NTT INDYCAR SERIES calendar.

Current third-generation IndyCar engines are twin-turbocharged 2.2-liter V6 DOHC engines producing approximately 550-750 hp depending on the level of boost used. Engines are currently supplied by Chevrolet and Honda.

The fourth-generation IndyCar engine will see its displacement increased from 2.2 to 2.4 L and its output increased from 550–700 to 900 hp (410–522 to 671 kW).

In addition, hybrid systems will also be introduced. The hybrid technology will include a motor, an inverter and an electrical storage device that will create energy recuperation from the braking system.

This is an important milestone for HPD, Honda and INDYCAR as the series enters the era of electrification, and it was a successful day, but there are still a lot of steps to go before the launch of the full hybrid power unit in 2024.

The all-new E85 2.4-liter biofuel engine was designed, simulated, developed, dyno-tested, engineered and assembled by the inspiring men and women of Honda at HPD in California. We set ourselves these challenges to grow our people and our technology here at HPD. We are very proud of the incredible team at HPD and our Honda “spirit of challenge”. There is still a very, very long list of things to accomplish before the power unit is tested in competition, but this is certainly a milestone for everyone at Honda Performance Development.
