Red Bull whistleblower reveals that their engines are made from glass

Earlier this week, a whistleblower out of Red Bull has revealed that their 2022 engine has been made of glass, citing this as the main reason for their constant DNFs this season. After suffering three DNFs out of six possible finishes, the ex-RB employee couldn't understand the choices made by the team to use glass over an aluminium alloy or even steel, and has said that RB have acknowledged porpoising as the main problem as it creates cracks in the engine.
