The Model Y has definitely been confirmed by Tesla CEO Elon Musk to make its debut as a 2018 model. This compact SUV will be based on the same platform as the Model 3, slotting below the full-size Model X SUV. Interestingly, the 2018 Tesla Model Y will complete the company’s lineup of four models that spells “S3XY” when read together. According to Musk’s ambitious plans, Tesla’s brand new crossover is expected “to see demand in the 500,000 to 1 million unit per year level”. As far as the release date is concerned, the upcoming Model Y is likely to hit the market in late 2017 or early 2018 shortly after the Model 3.
