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.

The Model Y is getting a stretched six-seater version, and Tesla just revealed all the specs. Here’s why you probably can’t buy it.

For many drivers accustomed to tame, underpowered daily commuters, even the base version of the Tesla Model Y can feel like a thrilling step up. But for those who want more than just a taste of performance, the standard Model Y doesn’t quite cut it. Fortunately, Tesla has something in the works for that crowd.
