The Cube, which is shorthand for Continental Urban Mobility Experience, is already being tried out at a proving ground here.
The robo-taxi will be put through its paces on the test track, which has a street infrastructure of junctions and curbs, before venturing out on public roads.
Continental says the robo-shuttle could help alleviate traffic problems in crowded cities.
The focus inside Cube is on privacy and communication for passengers who might otherwise baulk at being carried in a vehicle with no human driver to take over if things go wrong.
The interior is soothing, with foils, trim and upholstery materials offering what Conti calls "enhanced aesthetics, haptics, and durability."
The surfaces are also scratch and stain resistant to ensure the vehicle stays looking fresh and retains a new-car feeling.
"People in the car will be doing things other than driving it," says Alexander Jockisch, head of business development and marketing for surface materials in Continental's ContiTech division.
Cube gets around using laser sensors and technology familiar from the driver-assistance systems of many serial production vehicles.
Germany's Deutsche Bahn state-run railway has been testing similar shuttles.
"It's much more intelligent to operate driverless vehicles as often as possible than to have countless private cars that are often at a standstill, up to 23 hours a day on average," says Andree Hohm, who heads Continental's self-driving car project.
The German firm says its "feel-good cocoon" will go on display at the Frankfurt Car Show from Sept 16-24.
Continental last year teamed up with BMW, Intel and Mobileye to develop a platform for semi-autonomous and autonomous vehicles. In April 2017, Daimler and Bosch announced a similar tie-up.
According to a study by the consulting company Roland Berger, driverless vehicles will account for around a quarter of transportation services by the year 2030.
