FIA tweaks 2026 rules ahead of Miami GP to improve qualifying and safety

Before the Miami GP the FIA rolled out a few mid‑season tweaks to the 2026 rulebook. The changes cut the qualifying energy‑harvest cap from 8 MJ to 7 MJ and tighten start‑line procedures to curb the large speed gaps that have sparked safety concerns.

Why it matters:

• Qualifying has turned into a lift‑and‑coast puzzle, stripping the flat‑throttle excitement fans want.
• Opening laps have produced high‑speed bunching and serious incidents, prompting a safety outcry.
• The tweaks show the FIA can react, but they also underline that the 2026 cars remain bound by strict energy limits.

The details:

• Energy cap – Per‑lap MGU‑K limit now 7 MJ, giving a modest boost to qualifying power.
• Start‑line rules – New delta‑gap limits between the front two grid slots and tighter wheel‑spin monitoring to curb jump‑starts.
• Closing‑speed limit – A “max delta‑V” rule for the first three laps aims to keep cars from packing too tightly.

What's next:

Miami will be the first test. If qualifying laps regain flat‑throttle pace and start‑line incidents fall, the FIA may keep fine‑tuning within the current framework. If the core energy‑cap architecture still forces drivers to manage power over outright racing, deeper changes could be needed for 2027.
