Formula E Gen4 Car Revealed with 789bhp All-Wheel-Drive Powertrain

Formula E has officially introduced its Gen4 racing car, confirming major technological progress for the all-electric series. The vehicle will make its competition debut in the 2026/27 ABB FIA Formula E World Championship. Equipped with a 789bhp all-wheel-drive powertrain, the latest car ushers in a new era for Formula E. For the first time, drivers will have access to continuous all-wheel-drive capability during races. This feature is expected to influence teams’ strategies and energy recovery methods across the season. With the design representing Formula E’s largest technical update since inception, the series continues to serve as a proving ground for electric mobility. Key manufacturers are set to begin testing Gen4 development cars with efficiency and performance as the main targets.

The primary mechanical change for Gen4 is the full-race all-wheel-drive system. Unlike the Gen3 car, which only allowed limited use of all-wheel drive, the Gen4 can utilise this setup throughout each event. An active differential supports improved traction and adjustable energy distribution. The updated platform enables new options for power deployment and regenerative braking, allowing drivers and teams more flexibility with race management.

The Gen4’s performance is highlighted by a standard output of 450kW (603bhp), which rises to 600kW (789bhp) under Attack Mode. The regenerative braking system can now recover up to 700kW of energy, enhancing overall race efficiency. These technical credentials are designed to support longer and more competitive races.

Structural updates have also taken place, with the Gen4 car featuring an extended and widened chassis. It uses Formula 1-inspired wings at the front and rear, while the wheelbase has been stretched to 3080mm, making it longer and broader than its predecessor. This is intended to promote stable high-speed handling and provide manufacturers with scope to introduce unique car characteristics within the regulatory framework.

Sustainability is a major emphasis for the Gen4 project, with the car constructed entirely from recyclable materials and a minimum of 20% sourced from recycled content. The powertrain achieves close to total efficiency, recovering up to 40% of the car’s energy needs through regeneration.
