Ex‑F1 champion downplays rule‑change impact ahead of Miami

Former Grand Prix winner David Coulthard told the Up To Speed podcast that the 2026 rule tweaks rolled out before the Miami round are unlikely to produce an instant reading on the circuit. He points to Miami’s abundance of slow‑medium corners and lack of a “big, meaty” section as a factor that will mask any early effects. Still, Coulthard believes the changes will gradually restore more traditional racecraft.

Why it matters:

• Early‑season criticism of the 2026 power‑unit rules highlighted energy‑management bottlenecks and safety concerns.
• The FIA’s adjustments aim to curb “yo‑yo” racing, improve wet‑weather visibility and shift overtaking back to driver skill rather than pure electrical boost.
• How quickly teams adapt will influence the championship narrative for the rest of the season.

The details:

• Qualifying energy cap – limits on harvested energy force drivers to stay flat‑out longer, reducing lift‑and‑coast tactics.
• Higher recharge rates – quicker battery top‑ups temper long low‑power stretches between corners.
• Boost‑power ceiling – caps extra‑power windows to curb closing speeds and protect safety.
• Start‑procedure overhaul – new systems prevent dangerously slow get‑aways, targeting incidents like Oliver Bearman’s Suzuka crash.

What's next:

• Miami’s practice session has been extended to 90 minutes to give crews time to fine‑tune the new parameters.
• Coulthard expects the real impact to emerge over the next few races as teams learn to balance energy harvesting with slip‑stream tactics.
• If the tweaks succeed, overtaking may become fewer but more decisive, shifting focus back to driver positioning and race‑craft.
