Tesla Inc. is preparing to launch a longer, six-seat version of its Model Y sport utility vehicle in China, where the carmaker has been losing ground to domestic manufacturers with fresher lineups.

Tesla registered plans for a new six-seater Model Y L in China with a wheelbase of 3,040 mm, according to filing information published on China's industry ministry website on Wednesday.

Tesla has released teaser images of a six-seater version of its Model Y crossover for the first time. "Model Y L, see you in the golden autumn!" the EV brand said on a social media platform while hinting at a China launch by November.
