Images: The RoboCars of 2057

The LA Auto Show, which kicks off in mid-November, is holding its fourth annual Design Challenge. This year, it asked leading manufacturers to create a concept for a "RoboCar of 2057." What do Audi, General Motors, Honda, Mazda, Mercedes-Benz, Nissan, Toyota and Volkswagen think you'll be driving by then? The answers take into consideration environmental concerns, safety and your wildest dreams.

Audi came up with the Virtuea Quattro, a hydrogen-powered vehicle with artificial intelligence and a holographic exterior so that people can customize and change their car's look at whim without environmental impact.
