Overview

• Finalized Gen4 specifications promise permanent four-wheel drive, 600 kW peak power and 700 kW regenerative braking in the next-generation race car.
• Porsche, Nissan, Jaguar, Stellantis, Mahindra and Lola are crafting bespoke powertrains within a two-year homologation window and a 100 kg weight limit.
• First prototype drafts must be submitted by September under rules that lock in hardware changes for two seasons and limit mid-season tweaks to software.
• On-track testing of Gen4 prototypes is scheduled from late 2025 into early 2026 ahead of the cars’ debut at the start of Formula E’s 13th season.
• Teams view Gen4 as a high-performance laboratory for road-car electric vehicles, aiming to transfer efficiency gains to boost consumer EV range and charging performance.
