Formula E reveals Gen4 technical specs

Formula E’s Gen4 car is no longer just a rumor or a social-media spec sheet. Formula E and the FIA have already published the core numbers for the next-generation car, which is due to make its racing debut in the 2026/27 season. The package includes 450kW peak race power, 600kW in Attack Mode, permanent all-wheel drive, 700kW regenerative braking and a 55kWh battery. Formula E has also tied the new car to two aerodynamic configurations and to the series’ broader push on fast charging and road-relevant EV technology. ### So is the Gen4 car really a 600-horsepower machine? Formula E’s own materials describe Gen4 as a 600kW car in Attack Mode, not 600 horsepower. On its Gen4 explainer page, the series says the car will deliver 600kW, equivalent to about 815 bhp, while official launch materials list 450kW as peak race power and 600kW for Attack Mode overtakes. That means social posts describing “600hp peak power” understate the official number and mix up horsepower with kilowatts. (fiaformulae.com) The FIA said in its November 2025 announcement that Gen4 packs 50% more power than Gen3 Evo. The governing body also said the car is expected to exceed 335 kph and reach 0-200 kph in 4.4 seconds. ### What are the biggest technical changes teams are getting? (fiaformulae.com) The clearest changes are all-wheel drive, bigger energy capacity and much stronger regeneration. Formula E’s fact sheet says Gen4 will use active all-wheel drive, 700kW regenerative braking and up to 55kWh of race energy. The series also says the dual-motor system can recover nearly 50% of the energy used during a race, while the FIA’s earlier release described the car as almost 100% motor efficient and capable of regenerating 40% of race energy. (fia.com) Formula E also said the chassis will support two aerodynamic packages: a high-downforce setup for qualifying and a low-drag mode for races. The series has presented that as part of a broader redesign aimed at higher top speed and more flexibility between one-lap pace and race trim. ### Where does the 600kW charging claim fit in? (fiaformulae.com) Formula E introduced Pit Boost in January 2025 as a 600kW ultra-fast charging stop that adds 10% energy, or 3.85kWh, during a race. That system debuted in Season 11 at Jeddah, according to the FIA. The Gen4 announcements do not present 600kW charging as a brand-new Gen4-only feature; instead, the number matches the Pit Boost charging capability the series has already launched. (fiaformulae.com) That matters because some social posts bundled Pit Boost and Gen4 hardware into one package. The official documents show overlap, but they separate the race-car specifications from the charging feature’s rollout timeline. ### What is Jaguar actually teasing alongside Gen4? Jaguar TCS Racing revealed a Gen4 development car in April ahead of Formula E’s Gen4 Unleashed event. (fia.com) Formula E said the prototype previewed Jaguar’s next Formula E machine, while Jaguar’s own materials said the program is being developed for Season 13. Jaguar separately said on May 13 that its new luxury four-door GT will be called Type 01, and on May 16 that the car would appear at the Monaco E-Prix. (fiaformulae.com) In those releases, Jaguar Managing Director Rawdon Glover said the company had used Formula E know-how and Jaguar TCS Racing’s competition mindset in developing the road car. (fiaformulae.com) ### When will fans actually see Gen4 race? The FIA and Formula E have said Gen4 will make its competitive debut in the 2026/27 Formula E season. Formula E’s recent Gen4 materials and FIA releases both point to that timeline, with public demonstrations already under way through the Gen4 Unleashed event and team prototype activity. Jaguar’s Type 01, meanwhile, has been scheduled to appear around the Monaco E-Prix as the company links its road-car program to its Formula E platform. (media.jaguar.com) (fiaformulae.com)
