Ahead of the 2026 United
States 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 Austin?
• The Circuit of The Americas is a 5.513km lap combining a high-speed
first sector with two slower, more technical sectors, and carries
significant elevation change: a steep climb into Turn 1 followed by a
descent all the way to T11.
• The circuit has historically been very
bumpy, and ground movement means it is resurfaced frequently. For 2026,
the section from the entry of T9 to the entry of T11 has been resurfaced
and the bumps on the approaches to T12 and T19 have been smoothed. New
blue track limits lines have been added at most corners, where numerous
laps have been deleted in previous years.
• The high-speed T4 to T8
sequence is very wind sensitive, with strong effects on the car balance
through the first sector.
• The weather at Austin in late October is
variable, ranging from cold and wet to very hot, and track temperatures
can drop quickly as the sun sets during qualifying.
How do the 2026 regulations
influence the approach this weekend?
• Austin sits within the
season average for energy deployment and energy sensitivity, with two
active aero zones. The most sensitive straights are the runs to T1 and T12.
• The high-speed T4 to T8 sequence will be challenging, similar to the
first sector at Suzuka. Getting the driver pedal profile right here is
important, as it can otherwise result in a large energy spend and worse
deployment through the rest of the lap.
What are the tyre
challenges of the circuit?
• Pirelli have allocated the middle of
the range, C2 (hard), C3 (medium) and C4 (soft) – one step softer than the
C1/C2/C3 allocation used in 2025, but overall well suited to the circuit.
• The surface has lower roughness, and frequent resurfacing can make grip
evolution high throughout the weekend. Track temperatures can drop rapidly
through qualifying as the sun sets, making warm-up more difficult.
•
Qualifying: the soft is a clear single-lap tyre, but having the tyres
ready for T1 can be difficult to achieve. Good grip is needed from the
start of the lap to avoid a negative sliding spiral through the first
sector.
• Grand Prix: this track has a higher wear rate, although the
wear is distributed quite evenly across the four tyres. We expect
degradation to be driven by rear bulk overheating, then rear wear and then
front-left wear.
What are the strategic
considerations for the race?
• The race is close between a one-stop
and a two-stop. The softer compounds are likely to be favoured, and it is
possible that, once again, the hard tyre does not get used on Sunday.
•
With the soft being a strong race tyre, teams are incentivised to save
sets of it where possible in qualifying. This could create some jeopardy
on Saturday.
• Race pace is 30% more rewarding than qualifying pace.
Austin is predicted to be the easiest overtaking circuit of the season,
which puts the emphasis on race performance.
• The Safety Car
probability is low at 30%. The VSC probability is 50%, which is higher
than average.
