Verstappen: Red Bull’s home‑grown engine gets its real test in Melbourne

Max Verstappen says Red Bull’s long‑awaited in‑house power unit will face its first real race test at the Australian Grand Prix. Developed with technical support from Ford since 2022, the engine will power both the senior Red Bull car and its junior entries in Melbourne. Verstappen praised the reliability shown in pre‑season testing but warned the weekend will reveal how the unit performs under full‑race conditions.

Why it matters

Red Bull’s move to an internally developed power unit ends a decade‑long reliance on Mercedes‑supplied engines and could reshape the competitive hierarchy in Formula 1. A reliable, high‑output engine is essential for the team that has dominated the hybrid era, and its success will determine whether Red Bull can maintain its championship pace without external power‑unit partners. The outcome also impacts Ford’s re‑entry into top‑level motorsport, where a strong performance could accelerate its broader electrified‑power‑train ambitions.

The details

• Development timeline: Work began in early 2022, with Ford providing hybrid‑system expertise and component design support.
• Pre‑season testing: The unit logged over 1,200 km in Bahrain, showing competitive lap‑time stability and energy‑deployment consistency.
• Team rollout: The engine will fit three cars – Max Verstappen’s Red Bull, teammate Isack Hadjar’s RB entry, and Racing Bulls drivers Liam Lawson and Arvid Lindblad.
• Technical specs: 1.6‑litre V6 turbo‑hybrid, targeting 15 % more thermal efficiency than the previous Mercedes‑based unit while meeting the 2024 FIA power‑unit regulations.
• Strategic goal: Deliver a power unit that can be refined year‑on‑year, giving Red Bull full control over chassis‑engine integration.

What's next

Melbourne will be the first litmus test; a strong finish could cement confidence ahead of the season‑opening Bahrain GP. If the engine withstands the high‑downforce demands of the Albert Park circuit, Red Bull will likely accelerate development on cooling, energy‑recovery mapping, and power‑delivery curves for the next six races. Conversely, any reliability hiccup could force a rapid pivot back to customer engines, jeopardising the team’s championship aspirations and Ford’s return narrative.
