Doc 31 - Power Unit Information V2

Updated power unit performance parameters and exceptions for the 2026 Barcelona-Catalunya Grand Prix.

This document outlines the permitted power unit energy usage and power curves for the 2026 Barcelona-Catalunya Grand Prix. It specifies maximum recharge per lap (8.5 MJ in race), power reduction rates (100 kW/s), and ERS-K power limits as a function of car speed. Exceptions to standard power curves are defined for specific track sectors (e.g., T1-T2, T10-T12) where up to 350kW reduction is allowed. Overtake zones are detailed with activation lines and speed thresholds (e.g., 260 km/h at T2-T3). Regulations from Section C (Technical) and Section B (Sporting) govern these provisions, including power-limited sessions and detection logic for overtaking systems.
