Formula E’s new GEN4 car makes 600 kilowatts, about 815 horsepower, and it grew so much bigger than the car it replaces that the series could not fit it on some of the streets that built the championship. Our sister site PaddockNotes.net laid out the new car and the calendar that came with it this week. It arrives 87 kilograms heavier and 90 millimeters wider, enough that London’s ExCeL was judged too cramped to hold it, so the 2026-27 schedule answers with permanent circuits, a record 21 races that for the first time include the Circuit of the Americas in Austin.
The Real Export Is Energy Management
815 horsepower is the headline, and it is the least interesting number on the car. A Formula E race is an energy-managed event, a fixed budget of kilowatt-hours that has to last a race distance, and the driver who wins is the one whose car spends that budget most efficiently. That is the same problem every road EV solves between charges. The track just runs it at 600 kilowatts with a championship on the line, which is a faster way to learn it than a road car’s eight-year development cycle.
Turbochargers, disc brakes, and traction control all reached road cars from the racetrack first, and the pattern is the whole reason a series like this earns its keep. Paddock Notes built an entire Race-to-Road section around it, because the dividend is real and it is now being paid in electrons instead of octane. The thing Formula E develops under pressure is not speed. It is the management of heat, charge, and regeneration at the edge of what a battery can take.
What Actually Transfers
Porsche entered Formula E the same year it launched the 800-volt Taycan, and it has been open that the racing program is a development tool for the road side. The techniques that matter transfer directly: silicon-carbide inverters that waste less energy as heat, thermal management that lets a pack take a hard charge without cooking, and regenerative braking that claws back energy a friction brake throws away. Hyundai’s road EVs ride on an 800-volt E-GMP platform that uses the same playbook. The lab proves the hardware at 600 kilowatts, and a few model cycles later it is the reason your EV charges faster.
Active all-wheel drive and a 450-kilowatt sprint format are both new for GEN4, and each maps onto a road problem. The E-Prix Unleashed sprint runs the car flat out at a continuous 450 kilowatts, while the traditional race stays energy-managed, so one weekend now shows the same car in its two opposite modes. That tension, peak power against range, is the exact dial every dual-motor road EV has to set, and the torque-vectoring software that splits power between two axles on track is the same idea that makes a road EV stable and efficient. The technical rulebook behind all of it is the kind of thing Paddock Notes covers in its rules and tech desk.
The Number on the Window Sticker
205 miles on a 65-kilowatt-hour pack is what the cheapest electric truck in America now promises, and that number exists only because energy management got good enough to deliver it without a bigger, costlier battery. Range per kilowatt-hour is the metric the road EV market competes on, and it is the one that decides whether an affordable EV clears a usable range or strands the buyer. The power management that wins a race is what lets a cheap EV claim a real number, because the alternative, more cells, is the thing buyers cannot afford.
Austin gets two of these cars in February, the first time Formula E has run two United States rounds in a season since its debut year, with COTA on the calendar for February 6, 2027. That brings the rolling laboratory to the same American audience that buys the road cars its lessons end up in. Paddock Notes will cover the racing season lap by lap. GCBC will be watching where the technology lands, which is the window sticker, on the range line and the charging spec that decide what sells.
