Tesla plans to build a new pick-up truck, and an urban bus, and launch a sharing system of self-driving cars, the company's founder Elon Musk announced.
The projects are part of what the billionaire entrepreneur called a "secret" second master plan for the US electric car manufacturer posted on the company's website at a time it is looking to rebound from concerns over the safety of its "Autopilot" semi-autonomous driving mode.
"In addition to consumer vehicles, there are two other types of electric vehicle needed: heavy-duty trucks and high passenger-density urban transport," Musk wrote. "Both are in the early stages of development at Tesla and should be ready for unveiling next year."
He also restated his ambition to make all Tesla vehicles completely autonomous -- capable of driving without a human driver. Once regulators approve the technology, he said, "you will also be able to add your car to the Tesla shared fleet just by tapping a button on the Tesla phone app and have it generate income for you while you're at work or on vacation."
"In cities where demand exceeds the supply of customer-owned cars, Tesla will operate its own fleet," he added. The new road map follows a first master plan Musk unveiled in 2006, when he promised "an electric car without compromises" and a long-term vision of building "affordably priced family cars." Tesla Motors launched its first electric car in 2008 called the Roadster.
