Right now, the Tesla Model Y is only available with a five-seat configuration, but Elon Musk has promised a more practical seven-seater version is also coming for larger families. It's even on the options list when you go to order a Model Y, but you can't select it.

Production of the seven-seater Model Y wasn't due to start until sometime in 2021, but we now have a more specific timeframe. Speaking on Twitter in response to a user asking when deliveries for the seven-seater Model Y will start, Elon Musk announced the more practical version of the electric crossover will launch "probably in early Q4."

This means deliveries will start this October or November, which is earlier than we expected. Deliveries of the regular five-seat Model Y also started several months early back in March this year.

We're skeptical about the seven-seater version's practicality, however. The seven-seat Model Y adds an optional third row with two additional seats, but the rear legroom looks extremely limited in photos posted on Reddit earlier this year. The photos aren't high quality, but it's clear that even small children would struggle to sit in the third row comfortably. Rear legroom in the Model X is already restricted, but the Model Y is over ten inches shorter than the Model X.

Instead, the Model Y could be offered with rear-facing seats in the third row. When the Tesla Model S went on sale, the electric sedan was offered with rear-facing seats that could fit two children, but the option was discontinued. However, Elon Musk has hinted the option will return with seats large enough to fit adults as part of the upcoming Plaid update for the Tesla Model S later this year.

Pricing for the seven-seat version will cost an extra $3,000 over the standard five-seat Tesla Model Y, which starts at $52,990. Let's just hope the Model Y's shocking quality issues can be rectified before the seven-seat version goes on sale.
