Electric racing series pushes boundaries of EV technology
Formula E, the world's premier all-electric racing championship, is not just about speed-it's a testing ground for innovations that could soon power consumer electric vehicles (EVs). On December 6, 20 cars will compete on São Paulo's 2.93km street circuit, reaching top speeds of 322km/h (200mph) and accelerating from 0 to 96km/h (60mph) in just 1.82 seconds.
From race track to road: How Formula E leads the charge
Launched in 2014, Formula E has rapidly closed the performance gap with Formula One, the pinnacle of combustion-engine racing. While F1 cars still hold the edge in raw speed-topping 375km/h (233mph)-Formula E's latest generation of cars is nearly as fast, with future models poised to surpass them. Beyond the track, the series is driving advancements in battery efficiency, charging speed, and energy recovery that are already trickling down to consumer EVs.
The world's fastest EVs: Breaking records on and off the track
While Formula E cars dominate professional racing, the title of fastest production EV belongs to China's Yangwang U9 Xtreme. In September 2025, the road-legal model clocked 496.22km/h (308.34mph), making it the fastest production car of any kind. Experimental EVs, like Ohio State University's Venturi Buckeye Bullet 3, have pushed even further, achieving a two-way average speed of 549.4km/h (341.4mph).
Battery breakthroughs: Powering performance and sustainability
At the heart of Formula E's speed is its battery technology. Unlike early seasons-when drivers had to swap cars mid-race due to limited range-today's vehicles start with 52 kilowatt-hours (kWh) of energy, enough to power a fridge-freezer for nearly two months. But raw capacity is only part of the equation. Formula E batteries must deliver and absorb energy at 600 kilowatts (over 800 horsepower), nearly double the output of a Toyota Prius.
To achieve this, engineers stack hundreds of lithium-ion cells-each the size of an A5 notebook-into modules, separated by cooling plates and structural reinforcements. The batteries use a nickel-manganese-cobalt (NMC) chemistry, optimized for high-power applications. Despite these advancements, a single race can consume up to 90kWh, forcing teams to innovate further.
Regenerative braking and pit-stop charging: Game-changers for EVs
Formula E's solution to energy constraints relies on two key innovations. First, regenerative braking converts kinetic energy into electricity, eliminating the need for traditional friction brakes-a move that reduces particulate pollution. Tracks are even modified to include more braking zones, maximizing energy recovery.
Second, the Pit Boost system, introduced this season, allows cars to recharge mid-race. In just 30 seconds, drivers receive 3.85kWh at 600kW-four times faster than today's fastest commercial chargers. While designed to add strategic depth to races, this technology could soon alleviate "charge anxiety" for everyday EV owners by drastically reducing downtime.
"Range anxiety has kind of gone away. In its place has come charge anxiety. Can you actually get onto a charger when you want one, and how long are you going to be stuck there?"

From racetrack to driveway: Tech transfer in action
Many of Formula E's innovations are already making their way into consumer vehicles. Fortescue Zero's Elysia battery management system, which uses AI to detect faults and optimize performance, is now standard in all Jaguar Land Rover models. Faster charging, lighter materials, and smarter energy management-all honed in Formula E-are set to define the next generation of road cars.
"The racetrack is a laboratory, and always has been," says Beth Paretta, Formula E's Vice President of Sporting. "When those race cars launch from the starting line in São Paulo, they're carrying technology that will be in your car in a few years' time."
