Why Is Ferrari's NEW ENGINE UPGRADE So Scary For Mercedes & Red Bull And How Does It Work! | F1 2026

Ferrari are bringing their biggest weapon of the season to Austria this weekend. After Lewis Hamilton's stunning first Ferrari victory at Barcelona, the Scuderia are not slowing down. They are accelerating. For the Austrian Grand Prix at the Red Bull Ring, Ferrari are introducing the first of their permitted engine upgrades, the updated zero six seven slash six power unit, paired with a brand new Shell fuel developed specifically for it. This is the radical hot engine concept, built around a steel alloy cylinder head that lets Ferrari run combustion temperatures no rival would dare attempt. The goal is simple. Close the power gap to Mercedes that has held them back all season, and turn Hamilton's Barcelona breakthrough into a genuine title challenge. There is even a fascinating subplot, because Red Bull, who own the circuit Ferrari are upgrading at, are disputing the very ranking that allowed Ferrari to bring this engine in the first place. Let us go through the very latest on Ferrari's Austria engine upgrade, exactly how it works, and why this weekend could reshape the championship.
