With both of Tesla's most affordable models recently refreshed, let's see how these sedan and SUV siblings match up.

Tesla will start production of the new Model Y in February. And expect cheaper versions of the new Y to emerge in the coming months.

Tesla’s new EVs will use parts from existing platforms and aspects of the next-gen platform. Prices haven’t been confirmed but will likely sit around $30,000, undercutting the 3 and Y. In June, Tesla will launch a paid self-driving service in Austin and could expand it to other cities.
