LOS ANGELES — Google plans to build and launch onto city streets a small fleet of subcompact cars that could operate without a person at the wheel.
Actually, the cars wouldn’t even have a wheel. Or gas and brake pedals. The company says the vehicles will use sensors and computing power, with no human needed.
Google Inc. hopes that by this time next year, 100 of the two-seaters will be on public roads, following extensive testing. The cars would not be for sale and instead would be provided to select operators for further tweaking and have limitations such as a 25 mph top speed.
The announcement presents a challenge to automakers that have been more cautious about introducing fully automated driving and to government regulators who are scrambling to accommodate self-driving cars on public roads. Other companies are working on the technology but none as large as Google has said it intends to put such cars in the hands of the public so soon.
To date, Google has driven hundreds of thousands of miles on public roads and freeways in Lexus SUVs and Toyota Priuses outfitted with special sensors and cameras. But with a “safety driver” in the front seat, those vehicles were not truly self-driving.
Instead of the standard controls, the prototypes would have buttons to begin and end the drive. Passengers would set a destination. The car would then make turns and react to other vehicles and pedestrians based on computer programs that predict what others might do, and data from sensors including radar and cameras that read in real time what other objects are actually doing.
The route might be set by typing a destination into a map or using spoken commands, Chris Urmson, the leader of Google’s self-driving car team, told reporters Wednesday.
The car will be powered by electricity and could go about 100 miles before charging. Its shape suggests a rounded-out Volkswagen Beetle — something that might move people around a corporate campus or congested downtown — with headlights and sensors arrayed to resemble a friendly face.
Mark Reuss, global product development chief of General Motors Co., poked fun at the car’s look but acknowledged Google could become a force in the marketplace.
“I could wear it as a hat,” Reuss joked at an automotive technology forum in Detroit. “It’s cool. It’s like advanced. Like an old VW.”

Google Inc. made its name in Internet search and its money in advertising. What’s with the cars?
The Silicon Valley giant has a secretive research and development wing called Google X, where it invests time and money on what it calls “moon shots.”
Several years ago, Google started testing Toyota Priuses and then Lexus SUVs that it outfitted with an array of cameras and sensors, and heavy computing power.
So far, drivers have been behind the wheel for all 700,000 miles the cars have driven on public roads and been ready to take control if the electronics fail.
A NEW PROTOTYPE
Google noticed that employees who used the Lexuses would relax so much that they might not be ready to take over in an emergency. So the company set about developing a car that will not need a driver.
The prototype has two seats, a top speed of 25 mph and would be powered by electricity. There is no steering wheel or brake and gas pedals.
Google plans to test the car on closed courses this summer and then on public roads later this year. Once the company feels the car is safe enough, it wants to provide 100 prototypes to select members of the public.
Before the public can use truly driverless cars, however, California regulators need to finalize new rules allowing their operation. That process is due to be completed in the summer of 2015.
