Volvo self-driving car in Sweden (pictures)

The car relies mostly on technology currently available in production Volvos -- plus some extra green vinyl, for color.

Volvo also showed off a separate self-parking car, which can find an empty parking space and slot itself in, even if you're not in the car.

The black spot on the grille is the radar sensor, which is currently used in Volvo cars today.

The self-driving car was augmented with these GPS units on the roof. But, they're only used during testing. They won't be there in the final version.

This sensor module contains laser scanners and imaging. This is the bulk of the sensing equipment and is part of Volvo's current option packages.

This is the diagnostic terminal in the prototype. It makes for a heck of a conversation starter, but won't be there in the final version.

And the ubiquitous, shiny red button that shuts down the system. This, too, will not be there when this car goes on sale in 2017.
