Newgarden: "still a lot to be worked through" with hybrid engine
The current 2.2-liter twin-turbocharged V-6 engines in IndyCar are now paired with hybrid components, providing up to an additional 150 horsepower when deployed and regenerating power under braking. The testing program for the new hybrid system has been ramped up, with over 1,400 miles logged during a two-day test at Sebring International Raceway in August. There have also been recent tests at the 1.25-mile oval known as Gateway and Barber Motorsports Park in Alabama. Reigning champion Alex Palou and Josef Newgarden have both been involved in the testing and have shared positive feedback on the new system, although there is still ongoing development and fine-tuning before it is implemented for the Grand Prix of St. Petersburg in 2024.
