Tesla sold 21,900 electric vehicles in the first week of December in China, marking the company’s highest weekly sales in the fourth quarter of this year, according to Tesla China.

In November, Tesla set a record by selling over 73,000 units in China.

The Tesla Model Y topped the list as the best-selling passenger vehicle with 556,000 units sold last year.

To compete with rising market competition, Tesla introduced a limited-time discount on the Model Y. Buyers can receive a 10,000 yuan (around US$1,379) discount on outstanding loans.
