BEIJING (Reuters) -Tesla's Model Y L is "coming soon", the electric car company said on Chinese social media platform Weibo on Monday, having previously registered plans to introduce the new model in China.

The Model Y L is a six-seat version of its best-selling Model Y with a longer wheelbase. Tesla also shared a video of the new model in its Weibo post.

Tesla is refreshing its line-up in the face of growing competition that includes Xiaomi's recently launched YU7.

Elon Musk's Tesla registered an 8.4% fall in July sales of its China-made electric vehicles as Chinese competitors continue to offer lower-priced EVs against the backdrop of a price war that has bruised automakers, suppliers and dealerships.

A longer-range, rear-wheel drive Model 3 is also coming to the Chinese market, according to filing information published on China's industry ministry website in July.
