Although Tesla encountered brief pressure on parts supply, production was strong after the end of July, Cui Dongshu said.

Tesla China's sales in August are expected to reach 77,000 units, local media outlet Securities Times quoted Cui Dongshu, secretary-general of the China Passenger Car Association (CPCA), as saying today.

As Tesla's capacity utilization continues to rise, production is strong after the end of July, although it encountered brief pressure on parts supply, Cui said.

The Securities Times report provided no further information, and Tesla's sales of China-made vehicles are expected to be revealed by the CPCA later this month.

If the number is accurate, it would mean Tesla's China-made vehicle sales in August were up 173 percent from 28,217 in July and up 74 percent from 44,264 a year ago.

It would also be the second-highest number of China-made vehicles in Tesla's history, behind June's 78,906.

It's worth noting that the Shanghai plant has become an export hub for Tesla, so it will deliver fewer than 77,000 vehicles in China.

"Tesla makes cars for export in first half of quarter & for local market in second half," the company's CEO Elon Musk's account wrote on Weibo on August 18 in both Chinese and English.

On July 20, Tesla's second-quarter earnings report showed that Giga Shanghai now has an annual capacity of more than 750,000 vehicles, making it Tesla's largest factory in the world.

According to multiple media reports in August, Tesla upgraded its production line at Giga Shanghai between late July and early August, and will expand its annual capacity to around 1.1-1.2 million units after the upgrade is completed.

With the increased capacity of the Shanghai plant, the waiting time for Tesla vehicles in China is being significantly shortened.

The expected delivery date for the rear-wheel drive Model Y in China is now shortened to 1-4 weeks on August 31, down from 4-8 weeks previously, information on Tesla's China website shows.

The last change in expected delivery times for Tesla vehicles was on August 18, when the company shortened the wait time for all available models in China.

Tesla says no current plans to use new batteries in China-made vehicles
