Cadillac chief says Ferrari engine fully legal ahead of FIA meeting
Summary
Cadillac team principal Graeme Lowdon says Ferrari's 2026 power unit complies with the 16:1 compression‑ratio rule, as the FIA prepares a meeting to tackle rumours that Mercedes and Red Bull may be exploiting a loophole.
Cadillac team principal Graeme Lowdon says the Ferrari power unit for 2026 is “fully legal”, as the sport wrestles with rumours that some makers may be sidestepping the new 16:1 compression‑ratio limit.
Why it matters:
- A legal engine gives Cadillac a clear performance baseline and avoids costly disputes that could stall the debut season.
- If other brands are exploiting a loophole, the FIA may need to tighten rules, reshaping the power‑unit landscape ahead of the 2026 launch.
The details:
- The 2026 regs cap compression at 16:1 measured at ambient temperature; rumours suggest Mercedes and Red Bull can exceed it when the engine warms.
- Ferrari, Honda and Audi have asked the FIA for clarification; Lowdon says Ferrari’s unit is “black‑and‑white” compliant.
- Cadillac will use Ferrari’s engine for its first two seasons, praising the partnership and noting Ferrari also provides technical staff to the American team.
What's next:
The Jan. 22 FIA‑PU summit will confirm whether the current interpretation stands or a rule amendment is needed. A clear ruling will let Cadillac focus on shakedown work, while any changes could force a redesign before the 2026 opener.
