Vinci is a restartable, cryogenic, liquid-propellant rocket engine that powers the upper stage of Ariane 6. While development began in 1998 for the planned Ariane 5ME upgrade, funding for that programme shifted in 2014 to prioritize the development of Ariane 6, making Vinci the engine for the new launcher.
