FIA says it will intervene if teams exploit new start‑line rules

The FIA introduced a start‑line detection system for the Miami GP that triggers an MGU‑K boost and flashing warning lights when a car’s acceleration is below a set threshold. The body warned that any team trying to exploit the system will face penalties.

Why it matters:

A weak launch can cause pile‑ups, as seen when Liam Lawson’s poor start in Australia almost caused a high‑speed collision. The rule protects driver safety and stops teams from engineering a deliberate low‑torque start for a tactical advantage.

The details:

• Detection – Sensors record acceleration in the first seconds after clutch release and compare it to a preset baseline.
• Automatic response – If below the baseline, the MGU‑K gives a brief torque boost and flashing lights appear on the rear and sides.
• Penalty – Teams that deliberately tamper with the system will be penalised; otherwise the car simply loses the boost.

What's next:

The FIA will analyse Miami data and decide if the rule becomes permanent for the season. If kept, teams must map their power‑unit to deliver sufficient torque off the start, reshaping launch tactics.
