This car, called i Vision Dee, was presented at the Consumer Electronics Show in Las Vegas at an event attended by "Terminator" actor and former California governor Arnold Schwarzenegger.

BMW unveiled last year at this same show a car that could change hue but only from white to black and gray in between.

But the body of the new car can change in a rainbow of colors, in one solid hue or in stripes or checks.

BMW i Vision Dee is just an idea for now but it is supposed to shape the design of future cars from the luxury manufacturer.

For example, having driving data such as speed or direction flash on the windshield is scheduled to be an option as of 2025.

BMW has also raised the possibility of projecting augmented reality images on the windshield and turn it into a full-fledged screen with technology that mixes "real and virtual worlds."

The idea is to use software to create "the ultimate companion" offering a personalized driving experience, said BMW chief Oliver Zipse. The name Dee is an acronym for digital emotional experience.

Schwarzenegger joked about a prototype brimming with all this new technology.

"I was a little concerned because in most of my movies the machine was the enemy. Now they are the allies," he said.
