Robot cars put to the test over long distance

A Chinese auto manufacturer began a long-distance road test on its two self-driving cars on Tuesday.

The test showcases the country's ambition to chase international competitors in a red-hot industry that already boasts names such as Google, Audi, Toyota and BMW.

The two cars, manufactured by Changan Automobile in Chongqing, are scheduled to travel 1,900 kilometers from Chongqing to Beijing. The journey is expected to take five days.
