BEIJING (Reuters) -Tesla's China-made electric vehicle sales dropped 4% in August from a year earlier, as the U.S. automaker refreshes its aging lineup in China's hyper-competitive market.

On a month on month basis, however, deliveries of Model 3 and Model Y vehicles made at Tesla's Shanghai factory, including exports to Europe and other markets, totalled 83,192 units last month, up 22.6% from July, data from the China Passenger Car Association showed on Tuesday.

Top Chinese rival BYD extended a sales decline in its home market, which accounts for nearly 80% of its global shipments, to the fourth straight month in August.
