Ahead of the 2026 Miami
Grand Prix, Paul Williams, Chief Trackside Engineer shares insights into
the key technical factors that will shape the weekend.
What are the key technical challenges of the Miami circuit?
• The second of six Sprint events of the season creates an additional
challenge, although the single practice session length has been increased
by 30 minutes for this weekend
• The car setup must balance high-speed
and low-speed performance. The track has quick corners at the start and
end of the lap and two long straights connected by a slow, technical
middle section, requiring a setup compromise
• Being a temporary venue
around the Hard Rock Stadium, the track surface evolves significantly
throughout the weekend, meaning grip levels change from session to session
• The warm Florida climate often creates hot conditions which put
additional strain on both the car and drivers. Track temperatures
exceeding 50°C cause significant rear tyre overheating, especially through
the slow-speed middle section and during traction phases, making tyre
management critical throughout the lap.
How do the 2026 regulations
influence the approach this weekend?
• In 2026, our focus and
resource allocation for energy management has greatly increased,
particularly the time spent by drivers preparing in the simulator. This is
even more important as Miami is a Sprint event, limiting practice time
• The nature of the circuit at Miami makes the energy management challenge
slightly easier than at previous races, with plenty of opportunity to
harvest ahead of the long, energy-sensitive straights
• The FIA
regulation changes introduced ahead of Miami reduce the challenge;
however, we are still tackling the same problems around out-lap
preparation, optimising deployment and harvest, and developing a robust
plan for fighting other cars in the race
• The 2026 regulations define
three Straight-Line Mode (SLM) zones: the start/finish straight, the run
between Turns 8 and 11, and the back straight. The second zone will be
disabled in wet conditions, and if a WET hazard is declared, teams have a
specific exemption to raise the front ride height under Parc Fermé.
What are the tyre
challenges of the circuit?
• Softest compound allocation (C3-C5)
and typically high track temperatures lead to surface overheating,
particularly in sector 2 which is low speed, high traction
• Sector 1
can also be challenging for the front axle, with the T6/7/8 double apex
corner leading to high sliding and wear
• The long back straight can
make it difficult to prepare tyres in qualifying as the temperature can
drop too much before opening a lap particularly if managing traffic
•
The track temperature drops significantly during the afternoon due to the
dark track surface, which can lead to large balance changes throughout the
session.
What are the strategic
considerations for the race?
• Miami is one of the easiest tracks
of the season for overtaking. This puts a strong emphasis on race pace
over qualifying pace
• The Grand Prix is expected to be a 1-stop
featuring medium and hard tyres, although all three compounds are viable
race tyres. Some drivers could attempt an alternative strategy starting on
soft tyres and avoiding the hard
• Statistically, this track has a high
VSC (Virtual Safety Car) probability. A well-timed VSC could give drivers
yet to pit a significant advantage or incentivise drivers to make an extra
stop
• A small increase in tyre degradation could see the field shift
to 2-stop races.
