Are there any significant differences in terms of range and efficiency?
In general, both cars are equipped with the same (or at least very similar) battery pack of undisclosed capacity and a rear-wheel-drive powertrain. The Model Y is slightly bigger and offers more space inside.
According to the EPA, the range of the Model Y will be 5% lower than in the case of Model 3. We would've expected a bigger difference, so it will be interesting to see a real-world test.
The Model 3 SRP is currently the most efficient electric car ever tested according to EPA, and the Model Y SR is fourth, behind the Model 3 Long Range AWD and Hyundai IONIQ Electric.
