Overview
- The series released first images and confirmed headline specs: up to 600 kW peak output, a 55 kWh battery, permanent all‑wheel drive and as much as 700 kW of energy recuperation.
- The FIA says downforce is nearly doubled via larger front and rear wings, a revised floor and new airflow management, with high‑ and low‑downforce packages planned.
- Organisers project qualifying laps up to about five seconds quicker than Gen3, and FIA simulations suggest Formula 2‑level pace, though final performance depends on powertrain and software development.
- Bridgestone will replace Hankook as tyre supplier for the Gen4 era, with all‑weather tyres retained for now.
- Manufacturers have begun function tests, collective track running starts in mid‑November, and the cost‑controlled rules keep a spec chassis and battery while allowing open motor and software development.
