Autostadt is a popular tourist attraction featuring a museum, pavilions, factory tours and the two Car Towers where new cars can be picked up.

The idea for Autostadt was started in 1994 when the concept of documenting the stages of production of Volkswagen vehicles and how the company's operations were showcased at Expo 2000 in Hanover, Germany. In 1998, Autostadt, which is German for "Car City", broke ground on the former site of a fuel company bordering Volkswagen's Wolfsburg production plant.

Like the adjacent car plant, the site of Autostadt is on the north bank of the Mittelland Canal. The resulting complex is the work of more than 400 architects, created as a new urban center, close to downtown Wolfsburg.

The impressive Car Towers at the Autostadt in Wolfsburg, Germany are used for storage for new Volkswagens. The two 60 meter/200 ft tall glass car silos are connected to the Volkswagen factory by a 700 metre underground tunnel. When cars arrive at the towers they are carried up at a speed of 1.5 metres per second.

If customers chose the option to pick up their car from Autostadt, they are given free entrance, meal tickets and a variety of events building up to the point where the customer can follow on screen as the automatic elevator picks up the selected car in one of the silos.

The car is then transported out to the customer without having driven a single meter, and the odometer is thus on “0”.
