The current 2.2-liter twin-turbocharged V-6 engines are paired with hybrid components, which are small enough to fit inside the bell housing. The hybrid unit provides up to an additional 150 horsepower when deployed, similar to the push-to-pass system that has been a fixture in the series, and regenerates under braking. Automatic and manual regeneration methods have been a thorough part of the testing process.
A two-day test at Sebring International Raceway in August set the tone, with more than 1,400 miles logged courtesy of Chip Ganassi Racing’s Scott Dixon (Honda) and Team Penske’s Will Power (Chevrolet).
