Jonathan and Cleide Morris from Ventura, CA, asked two questions in the RACER Mailbag. Firstly, they inquired about the engine sound of the Alpine Hypercar/LMDh and Acura GTP, wondering what causes that noise. Marshall Pruett explained that the sound is a result of electronic systems working together, such as anti-lag and traction control, to keep the turbo spooled up during braking and manage wheelspin on corner exits. He also mentioned that the Acura ARX-06, which utilizes HPD’s 2.4L IndyCar design, produces the Chewbacca-like sound.
Their second question pertained to IndyCar’s decision to stick with the 2.2-liter twin-turbo engine and the upcoming hybrid system. They questioned why IndyCar didn’t opt for a “bring what you have” engine formula, allowing manufacturers to transfer race engines from GT3, GT2, or other series into IndyCar. They suggested that a Balance of Power system could be implemented to ensure competitiveness. Additionally, they wondered why IndyCar continues to use the heavy and unattractive aeroscreen, considering that other open-wheel series, including Indy NXT, use the halo.
