2026 Porsche GT4 Specs, Performance, Price – Porsche created an all-electric racecar with 1,000 horsepower. We had the opportunity to drive it today, despite the fact that it won’t be ready until 2026. Few automakers have even considered how racing can benefit from the electrification that is quickly taking over the automotive sector. Many businesses will find it difficult to survive if what sells on Sunday doesn’t sell on Monday.
However, Porsche is setting the standard. The company’s engineers learned what works and what doesn’t in electrified racing from their 2019 participation in Formula E. However, Porsche has to work harder on its GT racing program if it hopes to really bring that model back to the sales floor. The GT4 ePerformance is the first.
In contrast to the gorgeous Mission R, which serves as a visual representation of Porsche Motorsports’ future appearance, the GT4 ePerformance functions more as a mobile testbed. To make it all work, Porsche’s engineers, designers, and production team will utilize this to hone and mold the technology. This future vehicle has two motors and 1,000 horsepower. 2026 Porsche GT4 Specs

Exterior & Interior
Just before I was strapped into the cockpit of the electric racer prototype at the Circuit Ricardo Tormo in Valencia, Spain, I was told that it lacked traction control. I would further verify that fact. I pulled over on the front straight to have some space away from the camera car while I was filming.
When it was time to leave, I pressed the gas pedal, and when the car didn’t move, I was a little perplexed. I discovered after a minute that it was because I was performing a stunning burnout on my four wheels. Before long, the automobile was surrounded by a cloud of tire smoke.
Aside from that smile, I thought the GT4 had incredible grip, and the whole thing was a lot of fun. A lot of power? The vehicle does bounce out of corners, especially in the lower-spec racing mode, but the throttle curve is surprisingly forgiving. It was easy to dig a little deeper to gain speed since I was too sluggish entering one of the course’s several lengthy, off-camber corners.
Additionally, the brake pedal feels great and has a fair amount of travel. When switching from regenerative braking to conventional brakes, there is no discernible difference in feeling because the system is brake-by-wire. Lap after lap, it appears to be steady and optimistic. 2026 Porsche GT4 Specs

Engine & Performance
In qualifying mode, that equates to 800 kW of power, or precisely 1,072 horsepower. Only for brief bursts. Despite sharing a chassis, the car’s output in racing mode is over 600 horsepower, which is still much greater than the 718 Cayman GT4 Clubsport’s 425 horsepower.
The chassis’s capacity is divided across three distinct packs as it was not built to hold 82 kWh of batteries. Behind the driver, where the engine would typically be, is the largest, accounting for around half of the overall capacity. The third pack is located up front, where the fuel cell should be, and the second pack, which is about 20 kWh, rides shotgun on the passenger floor.
Two electric motors, one between the front wheels and the other between the rear wheels, are powered by those packs. Porsche experts informed me that although it has all-wheel drive, acceleration doesn’t actually require the front motor. Its main objective is to make regenerative braking more efficient.
The front stoppers end up exerting the most effort because as a car brakes, its weight transfers forward. This suggests that most of the regeneration is controlled by the front motor of the GT4 ePerformance. What is the cost? Porsche anticipates that the vehicle will generate up to 30 kWh of power during a 30-minute sprint race, allowing it to employ a smaller battery.
smaller brakes as well. Despite usually using smaller Brembos, the GT4 ePerformance is heavier and quicker than the gas-powered 718 Cayman GT4 Clubsport. I was a little miffed that the brake-by-wire technology, which flawlessly integrates the two systems, did not include ABS.
The automobile is much more balanced than a typical 911 because of the mild steering and the arrangement of the batteries. The GT4 often just pushes out wide when cornering too fast. In a single lap, I was able to lock all four brakes into the first corner without the car trying to swap ends with me. I simply pressed the left pedal and continued. Even the peak was built by myself.
How quickly did I make my first turn? The gearing utilized here meant that the top speed was a considerably more cautious 272 kph, or 169 mph, even though Porsche claims the car can reach a theoretical maximum speed of 300 kph, or 186 mph. I could feel the downforce forcing the vehicle into all the cracks and creases in the asphalt at that speed.
I didn’t realize the constraints until I switched to the maximum 1,072-hp qualifying option since Valencia’s front straight is so short. The car is a bit of a different animal when fully charged; it is aggressive around curves and requires me to use all of my brakes. After all, the tires and brakes remained the same even if the car’s power increased by almost 30%.
I backed the car up to a Level 3 charger to let it run its course between track sessions. It was usually ready to roll again once I’d had a drink and had had time to ponder. Porsche claims that racetracks equipped with 350-kW chargers could get the car from 5% to 85% in around 15 minutes. When a field of these devices is charging simultaneously, it’s likely that all the lights in the country will go out.

Circuits with that type of charging capability are not very prevalent these days. Porsche had to supply its own charger for the occasion because even this one was without one. However, track owners have time to fix the problem. Porsche anticipates having this vehicle available for consumers to use at its own racetracks by 2026.
There are plenty of reasons to be enthusiastic about this, despite the fact that I anticipate some clients to be dubious. The cost of operation per hour is a common metric used to evaluate race vehicles. With fewer moving parts and fluids to maintain than a conventional track-bred Porsche, the GT4 ePerformance might be a (relatively) affordable entry point into elite racing.
Conclusion
I can say that the Porsche GT4 ePerformance is an amazing vehicle, a powerful and self-assured prototype that offers me increasing hope for the future of motorsport, even in an emissions-free environment, but only time will tell in that respect. What about an electric 718 Cayman on the street? Porsche hasn’t said anything yet, but if this product continues to dominate Sunday sales, it will undoubtedly want something in shops on Mondays after 2026.
