BloombergTesla Inc is to start delivering China-built vehicles on Monday, a major milestone for CEO Elon Musk’s company as it mounts a push to expand in the world’s largest electric vehicle market. Musk is counting on the China plant to help build on momentum for the company in the world’s largest market both for electric vehicles and autos in general. Earlier yesterday, the China-built Model 3 was included on a list of vehicles qualifying for an exemption from a 10 percent purchase tax in the country. The locally built Model 3 would be priced from about US$50,000, Tesla said in October. Further helping Tesla, the China-built model this month qualified for a government subsidy of as much as about 25,000 yuan (US$3,572) per vehicle.
