How to Read F1 Telemetry: Mastering Speed Traces and Braking Zones in the 2026 Era

To the untrained eye, a Formula 1 speed trace graph looks like a jagged heartbeat. But for race engineers and dedicated analysts, these lines tell the absolute truth about a driver's performance. As Formula 1 enters the 2026 regulatory era—featuring a 50/50 power split between the internal combustion engine (ICE) and the battery—understanding how to read F1 telemetry has never been more critical.

Decoding the Speed Trace Graph

The foundational element of any telemetry dashboard is the speed trace. Plotted with speed on the Y-axis and distance (or time) on the X-axis, this graph reveals exactly where a driver is pushing the limits.

When comparing two drivers, look for the "V" shapes in the trace, which represent corners.

• The Braking Point (The Drop): Who starts decelerating later? A steeper, later drop indicates a driver braking deeper into the apex.
• Minimum Apex Speed (The Trough): The lowest point of the "V" shows how much speed the driver carried through the absolute center of the corner.
• Traction (The Climb): A steeper climb out of the trough shows superior throttle application and traction.

F1 Throttle and Brake Data in 2026

The 2026 power unit regulations have dramatically altered F1 throttle and brake data. With the MGU-K now outputting a massive 350 kW (up from 120 kW) and tasked with recovering 8.5 MJ of energy per lap, the telemetry looks different.

You will now frequently see drivers "lift and coast" much earlier at the end of long straights to regenerate battery power before hitting the mechanical brakes. If you are analyzing a speed trace and notice the speed plateau or dip slightly before the heavy braking zone, you are witnessing energy harvesting in action.

Furthermore, the introduction of the Manual Override Mode (MOM) allows trailing cars to deploy maximum 350 kW electrical power up to 337 km/h. When reading telemetry during an overtake, the attacking driver's speed trace will remain significantly higher at the top end of the straight compared to the defending driver, whose electrical deployment will taper off after 290 km/h.
