Each Apollo RT6 would cost 250,000 yuan (£31,000) - significantly less than previous models, Baidu said. "This massive cost reduction will enable us to deploy tens of thousands of [automated vehicles] across China," co-founder and chief executive Robin Li told the company's annual technology conference.
