Although it retired from prototype racing in 2017 and discontinued the R8 e-Tron due to slow sales, Audi isn't giving up on extreme race cars and all-electric drivetrains. The Germans just announced that they will unveil an aggressive looking supercar powered by batteries. It's called the PB 18 e-Tron concept and will make its public debut at the 2018 Pebble Beach Concours d'Elegance.

Audi didn't have much to say about it but explained that the "PB" in the name stands for Pebble Beach. Not exactly inspiring right? It also pointed out that it was developed at its new design center in Malibu. The concept car will be raced on the Laguna Seca track on August 23 and 25, in addition to being showcased at The Quail on August 24 and 26. And that's about all we know from the German brand.

Audi also released a teaser photo showing the supercar's front end. However, the picture is darkened, and we can only see the silhouette of the car. But it's enough to notice the Le Mans-inspired design with wide fenders and a canopy-style cockpit. It also has small cameras for side-view mirrors attached to the roof, wide wheels, and LED headlamps shaped like hockey sticks.

There's no word on whether this concept car previews a production model or not, but with the R8 e-Tron no longer available, Audi may be working on a new supercar. The gasoline R8 is also rumored to be discontinued after this generation, so the Germans may replace it with an all-electric vehicle. With its prototype efforts canned last year, the company's motorsport division has plenty of time to come up with a radical EV for the road. And needless to say, the PB 18 e-Tron could also spawn a track-only car.

We will find out more in late August so make sure you stick around for additional details.
