Formula E has been running for 12 years. In that time the cars went from needing a mid-race vehicle swap because the batteries couldn't last a full race distance, to a single car doing the full distance, to mid-race ultra-fast charging, to now the Gen4 generation, which the FIA describes as the fastest and most powerful Formula E car ever built. Peak power output is 600 kilowatts, a little over 800 horsepower, available during qualifying and specific scenarios. Regenerative braking capacity sits at 700 kilowatts. And for the first time in single-seater racing history, the car uses permanent four-wheel drive: two independent powertrains, one at each axle, managed separately.
The power figures are notable, but the structural change to the regulations is more significant for anyone who follows electric vehicle development. In previous Formula E generations, manufacturers could only develop the rear powertrain. Gen4 gives them freedom across the entire drivetrain and control systems: traction control algorithms, brake-by-wire calibration, differential management, torque vectoring between axles. These are exactly the systems that determine how a performance electric road car behaves. Jaguar, which has competed in Formula E since the championship's beginning, has been explicit that their involvement is about direct technology transfer and brand positioning. The Porsche Taycan, for instance, already uses knowledge developed through years of electric motorsport competition. Gen4 deepens that pipeline considerably. Manufacturers who were previously constrained to rear-drivetrain learning now have the full vehicle to work with. Four-wheel drive is now standard on most performance electric road cars, from the Model Y Performance to the Ioniq 5 N to the Rivian R2 dual-motor. The regulation change aligns the racing car with the technology landscape that matters to buyers.
The sustainability numbers in the Gen4 car are also worth noting. Visible components use 20% recycled materials. The tires are 65% renewable and recycled content, which the FIA notes is higher than most road car tires currently achieve. The battery contains no rare earth minerals. For a series that has positioned environmental credibility as part of its identity since season one, those are not trivial details. Safety has been upgraded to match the increased performance: the car is larger overall, runs on wider and grippier tires requiring power steering for the first time, and includes a substantially reinforced anti-intrusion panel. The cockpit has also been widened to give drivers more clearance at higher speeds. Close racing and frequent position changes have been a consistent feature of the format across all generations, and the FIA's stated intention is that Gen4 preserves that while adding the pace numbers that convert casual viewers into regulars.
Bottom line: The Gen4 regulations are the most manufacturer-friendly in Formula E's history, and the timing is deliberate. Electric road car technology has matured to the point where what happens in a Formula E garage has a plausible path to a dealership floor. Jaguar, Porsche, and any other manufacturer that stays in the series through this generation is not just racing. They are running a well-funded development programme that road car engineers feed from directly.
