Mastering COTA: US GP Telemetry & Corner Speed Analysis

The Circuit of The Americas is one of the most complete tests on the F1 calendar. In a single lap, drivers face a blind uphill hairpin, a sequence of fast direction changes, one of the longest straights of the season, and a slow, technical stadium section. A car has to be good everywhere to win here.

The 2026 United States Grand Prix (23–25 October) is the first race at COTA under the new rules, with active aero and Overtake Mode replacing DRS. It’s also a standard weekend with three practice sessions, so teams get far more running than they had on the Sprint weekend in Singapore.

This COTA track guide explains where lap time is gained and lost, and what to look for in the telemetry.

Turn 1: The Uphill Hairpin

The lap starts with COTA’s most famous feature: a steep climb up to the Turn 1 hairpin. The driver brakes while going uphill and can’t see the apex until the very top.

The gradient helps here. The slope slows the car, so braking distances are shorter than you’d expect for such a slow corner. In the telemetry, the brake trace starts relatively late and is brief, and the speed line drops steeply into a very low minimum speed at the apex.

The corner is also very wide, so drivers can take several different lines through it. Overtakes and opening-lap battles often start here.

Sector 1: The High-Speed Esses

From Turn 3 to Turn 6, the track drops downhill through a series of fast left-right direction changes. They’re often compared to Silverstone’s Maggotts–Becketts and Suzuka’s S Curves. This is where the car’s aerodynamics matter most.

What the car needs: Strong downforce and quick, stable responses to steering. The whole section is run in Corner Mode, with no active aero activation, so teams depend on the car’s high-downforce setting.

What the telemetry shows: On a good lap, the speed line through the esses forms a series of shallow dips rather than deep drops. The throttle stays mostly open, with only small lifts. If a driver has to lift or brake mid-sequence, look for a deeper dip in the speed line. It usually means the car became unstable at one direction change, and the driver loses speed through every corner after it. Mini-sector timing shows exactly which corner it is.

The bumps: COTA’s surface has been resurfaced several times since 2019, but it is still bumpy in places, especially through the esses. Teams have to choose between running the car low for downforce and running it higher for stability over the bumps. The risk is real: in 2023, Lewis Hamilton and Charles Leclerc were disqualified here for excessive plank wear, because the skid blocks under their floors were below the minimum thickness.

The Back Straight: Where Energy Decides Everything

After the slow Turn 11 hairpin, drivers start a back straight more than a kilometre long. It’s the main overtaking spot at COTA and the biggest energy test of the lap.

Corner exit sets up the straight

The run onto the back straight begins at the exit of Turn 11. A driver who gets on the throttle earlier and cleanly here carries that speed advantage all the way to Turn 12. In the telemetry, compare how quickly each driver reaches full throttle after the Turn 11 apex.

Active aero and the speed trace

The back straight is where active aero makes its biggest difference. Once the car switches to Straight Mode, drag falls and the speed line climbs steeply.

As the straight goes on, watch for these patterns:

• The electrical taper. Above about 290 km/h, electrical deployment starts to fade, and the speed line bends and flattens.
• Clipping. If the throttle trace shows 100% but the speed line plateaus before the braking point, the battery has stopped deploying or the car is super clipping to recharge.
• The top-speed gap. Comparing top speeds at the end of the straight shows which teams have the best balance of low drag and energy management.

Overtake Mode on a long straight

A long straight is ideal for Overtake Mode. A chasing car within one second at the detection point keeps full 350 kW deployment up to around 337 km/h, while the car ahead starts to fade from about 290 km/h. On a straight this long, that speed difference keeps growing. Our Overtake Mode guide explains the full mechanics.

Turn 12: braking and harvesting

The straight ends at Turn 12, one of the heaviest braking zones on the lap. It’s the main overtaking point, and it’s also where much of the lap’s energy is recovered. The MGU-K harvests hard as the car slows from top speed. The car also has to stay stable here: a bumpy braking zone at the end of a long straight is a common place for drivers to lock up.

Energy is tightly limited in qualifying at Austin, where the recharge limit is 8 MJ per lap. Drivers who manage it best will have the most power left for the back straight.

Sector 3: The Stadium and the Triple Apex

After Turn 12, the track winds through the stadium section (Turns 12–15). These slower corners, often compared to Hockenheim’s stadium, test traction and braking stability. Next comes the long, multi-apex right-hander at Turns 16–18, where the car’s grip is loaded up for a sustained stretch and tyre temperature builds quickly.

The final corners lead onto the main straight. A good exit from Turn 20 is important for setting up an overtaking attempt into Turn 1 on the next lap.

Tyres and Race Strategy

With three practice sessions, teams will have proper long-run data this time. Friday’s FP2 long runs are the best guide to how the new C2 Hard compares with last year’s C1 through Sector 3’s heavy, sustained loading. Our guide to reading tyre degradation from long runs shows how to read that data.

The Title Picture

Antonelli arrives in Austin 340 points to Russell’s 238, with 125 points still available after this race. He clinches the championship on Sunday if he wins, Russell finishes ninth or lower, and Hamilton finishes fifth or lower. If he finishes second, it isn’t enough, even if Russell fails to score. Our title math breakdown covers every scenario.

FAQ

How long is the Circuit of The Americas? 5.513 km, with 20 corners. The US Grand Prix runs over 56 laps, a total of 308.405 km.

Where is the best overtaking spot at COTA? The braking zone into Turn 12, at the end of the long back straight. Turn 1, at the top of the hill, is the second-best opportunity.

What makes COTA’s Sector 1 difficult? The fast, downhill esses from Turn 3 to Turn 6 need high downforce, a stable platform and precise direction changes. All of it happens on a bumpy surface.

Is the 2026 US Grand Prix a Sprint weekend? No. 2026 is a standard weekend with three practice sessions, qualifying on Saturday and the race on Sunday.

Can Antonelli win the title in Austin? Yes. He clinches if he wins, Russell finishes ninth or lower, and Hamilton finishes fifth or lower.
