Tesla Inc. (NASDAQ:TSLA) shares continued recent advances on Friday after Bloomberg reported that the electric vehicles maker will start delivering its first China-built cars on Monday.

The newswire said the first 15 units of Tesla’s Model 3 sedans made at its new Shanghai facility will be delivered to company employees on December 30, citing a representative of the company.

Tesla chief executive Elon Musk has said he expects the China plant to be producing at least 1,000 cars a week by year-end.

The company’s shares have gained 78% in the past three months, buoyed by a surprise move to profit in its third-quarter and excitement about its plans for China and demand in Europe.

In pre-market trading on Friday, Tesla shares were 1.1% higher at US$435.60.
