Ralf Brandstätter, the CEO of the Volkswagen Brand, took to LinkedIn today to reveal a new surprise performance EV concept: the ID.X.

Based on the ID.3, Volkswagen’s in-house experimental development department swapped out the 62 kWh battery for a much bigger 82 kWh one and swapped in some of the ID.4 GTX’s performance parts. Thanks to the changes, the car sends 245 kW (328 hp) to all four wheels, not unlike the Golf R.

According to Brandstätter’s post, the team also improved the chassis, the infotainment and, as you can see, modified the car’s appearance. It also managed to lighten the ID.X by 200 kg (440 lbs).

All in all, the changes mean a 0-100 kph (0-62 mph) time of 5.3 seconds. That’s about half a second slower than the Golf R’s claimed time but it is faster than the GTI Clubsport 45’s time of 5.6 seconds.

Unfortunately, Brandstätter is quick to point out that the ID.X will not be put into production. The idea, though, came from how much the team enjoyed working on the ID.4 GTX.

“We just introduced the ID.4 GTX. Our first electric performance model is very well received,” said Brandstätter, as translated by LinkedIn. “Even with our engineers – because with it they have discovered the fun of developing high-performance electric cars. And so we just let them do it.”

Volkswagen recently unveiled the ID.4 GTX, the first member of the GTX line of performance electric vehicles the brand is planning. It gets 295 hp, a 77 kWh battery, 298 miles of range (WLTP), and can hit 62 mph in 6.2 seconds. In Germany it costs €50,415 ($60,623).
