Porsche dropped all the details about its facelifted Taycan EV earlier this month, but since its Audi e-tron GT cousin didn’t originally hit the market until spring 2021, a year after the Porsche, we’ve still got a few months to wait before the Audi team reveals how it’s upgraded their electric four-door coupe.

But as these pictures show, development work is well underway on both the regular GT and the hotter RS derivative. Our spy photographers caught both during testing, reminding us that while the base version looks suitably sporty with its low roofline and sloping tail, the RS model is a much more aggressive package.

Both cars have camo wrap covering their noses and tails, but we can see that the stock e-tron GT has a faintly evil smile thanks to the shape of the side air intakes under its LED headlights. The RS, on the other hand, has a more purposeful look about it with a trapezoidal side air intake beneath each lamp unit and another vertical vent sited just ahead of each front wheel.

The RS also displays a small trunklid spoiler, and larger wheels whose more open design sacrifices some aerodynamic qualities to let us – and cold air – see its larger brakes. The RS gets huge 10-piston calipers, just like the Taycan, and a close-up shot of this RS’s driver-side front wheel even reveals Porsche branding on the prototype’s red calipers. Don’t expect that still to be there when the production version is revealed later this year, or when the 2025 model year cars land in dealerships next spring.

We can’t see any changes to the head- or tail lights in either car, and the fact that Audi has chosen not to cover them suggests it won’t fit the facelifted lights until later in the development program. We also can’t see what changes Audi has made to the powertrain and battery setup, but looking at what Porsche did to the facelifted Taycan gives us a good steer.

The Taycan’s new Performance Battery Plus now has a capacity of 105 kWh, instead of the current model’s 93 kWh. Porsche hasn’t yet revealed official EPA ranges, but in its own real-world test, it found that the greenest 2025 Taycan could go up to 365 miles (587 km) on one charge — around about 120 miles (191 km) better than the current model’s official EPA rating.

Porsche also improved the performance of every Taycan in the lineup, which now tops out with the 939 hp (952 PS) Turbo S. And while we’re not expecting the GT RS to go that far, its guaranteed to make well over the 637 hp (646 PS) pumped out by the current car. The base GT (currently 523 hp / 530PS) will also be gifted a few horses.
