Volkswagen returns to racing.

Volkswagen has released dark images of a futuristic race car that burns no gasoline.

Spotted by British magazine Autocar, the photos were released on one of the company's social media accounts. An earlier version of this story noted we had no idea which race series it was built for, but Volkswagen has come forward and released more information about the prototype.

We were wrong; it's not the Garage 56 entry for next year's 24 Hours of Le Mans. The prototype shown in the pictures will tackle next year's Pikes Peak Hill Climb. It takes the form of a sleek, low-slung model with pronounced fenders, a dome-like roof, and a massive wing out back.

This won't be the German brand's first attempt at setting a Pikes Peak record. It built a twin-engined, 652-horsepower Golf GTI in the mid-1980s and tried to takes first place in the event in 1986 and 1987, failing both times. This explains why photos were accompanied by the hashtag "#UnfinishedBusiness."
