BERLIN -- Audi plans to unveil its Grandsphere concept on Sept. 2 ahead of the Munich IAA auto show.
The online unveiling will take place at 19:00 CEST.
The news, first reported in UK publication AutoCar, was confirmed to Automotive News Europe by an Audi spokesperson.
The Grandsphere is part of a trio of electric concept vehicles intended to define how users will interact with vehicles with Level 4 autonomous capabilities, which can take over driving under set conditions.
Formerly code-named "Landjet," the Grandsphere is reportedly a successor to the A8 luxury sedan and is due to reach the market in 2025.
The vehicle is the result of the high-tech Project Artemis venture, backed by the resources and technologies of the entire Volkswagen Group, which is focusing on advanced autonomous driving capabilities.
Details about the Grandsphere remain sparse, although a sketch of the vehicle was posted on the LinkedIn page of the company's product placement head, Benjamin Honal, showing a dramatically sloped rear roofline resembling a fastback sedan.
In a recent interview with Automotive News Europe, Audi CEO Markus Duesmann said the automaker would use the Munich show to give a glimpse of how the automaker's new models will look. He declined to provide additional details.
The brand recently unveiled two other concepts: the Skysphere roadster, which features a variable-geometry wheelbase that transforms between autonomous Grand Tourer mode and a sports car; and the Urbansphere, which appears to have a higher roofline, giving it the appearance of a sporty crossover vehicle. The Urbansphere is set to debut sometime in 2022.
