Google is to start building its own self-driving cars, rather than modifying vehicles built by other manufacturers.
The car will have a stop-go button but no controls, steering wheel or pedals.
Pictures of the Google vehicle show it looks like a city car with a "friendly" face, designed to make it seem non-threatening and help people accept self-driving technology.
Co-founder Sergey Brin revealed the plans at a conference in California.
"We're really excited about this vehicle – it's something that will allow us to really push the capabilities of self driving technology, and understand the limitations," said Chris Urmson, director of the company's self-driving project.
He added that the cars had the ability to "improve people's lives by transforming mobility".
