A 1156-hp electric SUV that hits 100 in 2.5 seconds, and you can see it for free
Porsche is giving the Cayenne Electric its Japanese debut trackside at the Tokyo E-Prix — 1156 hp, 2.5 seconds to 100 km/h, and no race ticket needed to get close.
Porsche could have shown the new Cayenne Electric on a dull stand under studio lights. Instead, it is rolling the car straight into the thick of a night race. The all-electric SUV gets its Japanese premiere at Formula E in Tokyo — on 25–26 July, on the track around Tokyo Big Sight, as part of the 2026 TDK Tokyo E-Prix. And here is the part that matters: you don’t need a race ticket to see it in the metal — it will sit in the free Fan Village zone.
The venue was not chosen for a pretty picture. The Cayenne Electric has to prove one simple thing: a big electric Porsche is not a family crossover with a battery bolted in. It is a transfer of racing technology into the brand’s most profitable segment. To make sure the hint lands, a Porsche 99X Electric race car will stand right beside it on the stand. The comparison with Formula E is built straight into the presentation — and there will be nothing to argue about.
And now the numbers — and they are almost indecent. In Launch Control mode, the Cayenne Turbo Electric’s powertrain delivers up to 850 kW. That is 1156 hp and 1500 Nm. Zero to 100 km/h — 2.5 seconds. Zero to 200 km/h — 7.4 seconds. Top speed — 260 km/h. In normal mode it settles for “just” 630 kW, or 857 hp, while the Push-to-Pass function throws in another 130 kW (176 hp) for ten seconds. For a heavy SUV, this is already supercar territory.
The base version is noticeably calmer — but you couldn’t call it weak with a straight face. 300 kW (408 hp) in normal mode and 325 kW (442 hp) under Launch Control. Torque of 835 Nm, 0 to 100 km/h in 4.8 seconds, top speed of 230 km/h. Both versions are all-wheel drive, with the electronically controlled Porsche Traction Management system.
Under the floor sits a new 113 kWh battery with dual-sided cooling. WLTP range reaches up to 642 km for the Cayenne Electric and up to 623 km for the Turbo. The 800-volt architecture allows DC charging at 390 kW, and up to 400 kW in ideal conditions. From 10 to 80% the battery refills in under 16 minutes. In ten minutes at the charger you can claw back up to 325 km of range on the regular version and 315 km on the Turbo.
And here is the detail that finally ties this SUV to the racetrack. Recuperation reaches 600 kW — Formula E level. Porsche claims that in everyday driving up to 97% of braking is handled by the electric motors alone, without troubling the mechanical brakes. For a heavy premium SUV, that is not only about efficiency. It is also about the lifespan of brakes that barely wear out.
On the market, the Cayenne Electric goes up against the BMW iX, Mercedes-Benz EQE SUV, Lotus Eletre and the coming wave of big electric Chinese models. But Porsche plays by its own rules. Not the biggest screen. Not the price. But a mix of supercar acceleration, fast charging and the Cayenne name — the very one that long ago turned into a money machine for the brand.
