Audi Lunar Quattro

The Audi Lunar Quattro is a small four-wheeled lunar rover created in 2015 by PTScientists, a team of engineers from Germany, with the support of Audi and a number of scientists and companies from different countries. It is built from magnesium-based alloys, has a total mass of 35 kilograms and can reach a maximum speed of 3.6 kilometres per hour. Four electric motors drive it, powered by solar panels and lithium-ion batteries. The rover made a brief appearance in the film Alien: Covenant as part of a collaboration between Audi and Twentieth Century Fox. A flight to the Moon aboard a SpaceX Falcon 9 rocket was planned for October 2021 but did not proceed, and no further launch announcements have been made, so the rover has not flown.
