Mexico City Porsche 992.2 Cup Track Guide: Official Baseline Data

Mexico City Porsche 992.2 Cup Track Guide: Official Baseline Data

This guide is built from the exact Valor Official Baseline for Autódromo Hermanos Rodríguez — Grand Prix + Porsche 992.2 Cup. It is not a generic track description and it is not reconstructed from internet braking markers. The numbers below come from the canonical baseline CSV, the reviewed Valor corner map and the corresponding turn profile in the August 16 data pack.

Turn numbering follows Valor's reviewed map for this exact layout. Baseline speed is converted from the recorded meters-per-second trace to mph. Brake and throttle are the recorded 0–100% channels. Conditions, setup, fuel, tire state and driving line can move the exact targets, so use the data as a measured reference rather than a command to copy blindly.

Baseline snapshot

• Mapped turns: 18

• Meaningful brake events: 10 of 18 turns

• No-brake / flow sections: 8

• Peak speed in the reference trace: about 159.6 mph

• Telemetry-integrated reference time: approximately 1:41.89

• Average turn-profile confidence: 100.0/100

• Heaviest brake zones: Turn 1 74.0%, Turn 4 71.2%, Turn 14 70.1%

• Largest recorded speed reduction: Turn 1, roughly 159.6 → 53.0 mph

• Slowest mapped minimum: Turn 15 at about 35.1 mph in gear 1

The integrated time is calculated from the reference trace's recorded position and speed because the distributed baseline CSV does not contain the simulator's lap-clock channel. Treat it as a telemetry-derived reference time, not an official iRacing timing result.

What the baseline says about this combination

This combination is braking- and rotation-heavy. Ten of the 18 mapped turns contain meaningful brake input, and several feed directly into another direction change rather than a long clean exit.

Turn 1 is the largest stop, from about 159.6 mph at brake onset to 53.0 mph. Turn 4 is another major reduction, to roughly 46.6 mph in first gear. Turn 15 is the slowest minimum in the entire reference at about 35.1 mph.

The slow-corner character also shows up in throttle timing. Turns 8 and 11 require noticeably more patience before full throttle than most of the lap. In this car, simply attacking every brake marker misses the larger job: rotate the car cleanly enough that the next acceleration phase is usable.

Turn-by-turn baseline guide

Turn 1 — right

This is a major braking zone. The baseline begins the brake event at roughly 159.6 mph, peaks at 74.0% brake, reaches about 53.0 mph in gear 2, and exits the mapped segment around 55.5 mph. Brake release is complete roughly 8 m before the minimum-speed point, so the reference finishes most of the deceleration before the slowest point rather than dragging brake deep into it.

Turn 2 — right

This is a light-brake adjustment. The baseline begins the brake event at roughly 64.3 mph, peaks at 18.8% brake, reaches about 54.3 mph in gear 2, and exits the mapped segment around 55.5 mph. Brake release is complete roughly 25 m before the minimum-speed point, so the reference finishes most of the deceleration before the slowest point rather than dragging brake deep into it.

Turn 3 — right

The reference uses no meaningful brake input here. It carries about 59.8 mph at minimum speed in gear 2 and builds to about 84.4 mph by the mapped exit. If your trace shows a clear brake spike here, first check line, steering load and whether the previous corner has left the car out of position.

Turn 4 — right

This is a major braking zone. The baseline begins the brake event at roughly 134.6 mph, peaks at 71.2% brake, reaches about 46.6 mph in gear 1, and exits the mapped segment around 47.7 mph. Brake release is complete roughly 11 m before the minimum-speed point, so the reference finishes most of the deceleration before the slowest point rather than dragging brake deep into it.

Turn 5 — right

This is a speed-management braking zone. The baseline begins the brake event at roughly 57.5 mph, peaks at 33.0% brake, reaches about 41.3 mph in gear 1, and exits the mapped segment around 62.9 mph. Brake release is complete roughly 19 m before the minimum-speed point, so the reference finishes most of the deceleration before the slowest point rather than dragging brake deep into it. Full throttle arrives about 13 m after minimum speed, a relatively quick power transition.

Turn 6 — left

This is a speed-management braking zone. The baseline begins the brake event at roughly 74.3 mph, peaks at 35.8% brake, reaches about 55.8 mph in gear 2, and exits the mapped segment around 55.8 mph. Brake release finishes essentially at the minimum-speed point, so braking and rotation are tightly linked.

Turn 7 — left

The reference uses no meaningful brake input here. It carries about 49.3 mph at minimum speed in gear 1 and builds to about 67.5 mph by the mapped exit. If your trace shows a clear brake spike here, first check line, steering load and whether the previous corner has left the car out of position.

Turn 8 — left

This is a firm controlled braking zone. The baseline begins the brake event at roughly 106.8 mph, peaks at 48.5% brake, reaches about 81.8 mph in gear 3, and exits the mapped segment around 89.9 mph. Brake release is complete roughly 33 m before the minimum-speed point, so the reference finishes most of the deceleration before the slowest point rather than dragging brake deep into it. The reference waits about 23 m after minimum speed before reaching full throttle. Do not force the power phase before the car is ready.

Turn 9 — right

The reference uses no meaningful brake input here. It carries about 94.6 mph at minimum speed in gear 3 and builds to about 99.9 mph by the mapped exit. If your trace shows a clear brake spike here, first check line, steering load and whether the previous corner has left the car out of position.

Turn 10 — left

The reference uses no meaningful brake input here. It carries about 93.9 mph at minimum speed in gear 3 and builds to about 95.4 mph by the mapped exit. If your trace shows a clear brake spike here, first check line, steering load and whether the previous corner has left the car out of position.

Turn 11 — right

This is a speed-management braking zone. The baseline begins the brake event at roughly 102.3 mph, peaks at 33.6% brake, reaches about 78.6 mph in gear 3, and exits the mapped segment around 86.7 mph. Brake release is complete roughly 19 m before the minimum-speed point, so the reference finishes most of the deceleration before the slowest point rather than dragging brake deep into it. The reference waits about 28 m after minimum speed before reaching full throttle. Do not force the power phase before the car is ready.

Turn 12 — left

The reference uses no meaningful brake input here. It carries about 91.2 mph at minimum speed in gear 3 and builds to about 100.8 mph by the mapped exit. If your trace shows a clear brake spike here, first check line, steering load and whether the previous corner has left the car out of position.

Turn 13 — right

The reference uses no meaningful brake input here. It carries about 103.3 mph at minimum speed in gear 4 and builds to about 107.5 mph by the mapped exit. If your trace shows a clear brake spike here, first check line, steering load and whether the previous corner has left the car out of position.

Turn 14 — right

This is a major braking zone. The baseline begins the brake event at roughly 134.0 mph, peaks at 70.1% brake, reaches about 70.3 mph in gear 2, and exits the mapped segment around 74.6 mph. Brake release is complete roughly 33 m before the minimum-speed point, so the reference finishes most of the deceleration before the slowest point rather than dragging brake deep into it.

Turn 15 — right

This is a firm controlled braking zone. The baseline begins the brake event at roughly 87.0 mph, peaks at 57.3% brake, reaches about 35.1 mph in gear 1, and exits the mapped segment around 36.5 mph. Brake release is complete roughly 25 m before the minimum-speed point, so the reference finishes most of the deceleration before the slowest point rather than dragging brake deep into it.

Turn 16 — right

The reference uses no meaningful brake input here. It carries about 48.8 mph at minimum speed in gear 1 and builds to about 69.5 mph by the mapped exit. If your trace shows a clear brake spike here, first check line, steering load and whether the previous corner has left the car out of position.

Turn 17 — right

This is a speed-management braking zone. The baseline begins the brake event at roughly 77.4 mph, peaks at 39.9% brake, reaches about 54.0 mph in gear 2, and exits the mapped segment around 56.1 mph. Brake release is complete roughly 30 m before the minimum-speed point, so the reference finishes most of the deceleration before the slowest point rather than dragging brake deep into it.

Turn 18 — right

The reference uses no meaningful brake input here. It carries about 67.6 mph at minimum speed in gear 2 and builds to about 109.4 mph by the mapped exit. If your trace shows a clear brake spike here, first check line, steering load and whether the previous corner has left the car out of position.

How to use this guide in Valor

The fastest way to use these numbers is not to memorize every speed before you drive. Pick one corner, complete a clean lap, and compare the trace.

If your minimum speed is lower than the reference, look backward at brake timing, release shape and steering load before assuming the solution is simply to enter faster. If your minimum speed is close but exit speed is weak, inspect throttle timing and how much steering remains when power is applied. If you are braking in a reference no-brake section, determine whether the problem actually began in the previous corner.

Valor can use the same official baseline as the comparison target in the live coaching/overlay workflow and in post-session analysis. Learn how Valor baselines work or download Valor.
