During Tesla’s 2017 first quarter earnings call on Wednesday, Elon Musk took the opportunity to share new information about the hotly anticipated Model Y.

The Model Y is expected to be a compact SUV model compared to the larger Model X. Production of the vehicle, which will be based on an entirely new platform, is expected to begin in 2020.

Musk said the Model Y will abandon the current 12-volt battery architecture, which should make manufacturing the car much easier since it will cut back on the wiring necessary for current configurations.

It’s unclear when the Model Y will be unveiled or sold, but if we go by the Model 3’s timeframe—it was unveiled last March and is expected to be delivered by late 2017—perhaps Model Y deliveries will arrive in 2021.

Tesla sold a record a number of vehicles in the quarter

Musk also said Tesla sold a record 25,501 vehicles in the previous quarter—a new high for the Tesla. However, the company still needs to show it can handle large scale manufacturing.

One of the biggest criticisms aimed at Tesla is its inability to manufacture vehicles in large quantities. The roll-out phase of the Model S and Model X were plagued by delays and there’s a lot of skepticism Tesla won’t ship out enough Model 3 models by the end of the year as promised.

Tesla has already stated it has a goal of delivering 1 million vehicles by 2020. The upcoming Model 3 and brand new Model Y will be vital in reaching that number.
