2015 Tesla Model X vs 2017 Tesla Model 3
Which is bigger, the 2015 Tesla Model X or 2017 Tesla Model 3?
Key dimensions: length, width, height
While not a massive leap, the 2015 Tesla Model X is 35.7 cm longer than the 2017 Tesla Model 3. The width difference of 14.9 cm is negligible between the 2017 Tesla Model 3 and 2015 Tesla Model X, meaning both will feel similar when navigating narrow city lanes. With a 23.9 cm height advantage, the 2015 Tesla Model X is better suited for those who prefer a higher view of the road ahead. The extra 3.1 cm of clearance helps the 2015 Tesla Model X feel a bit more robust in daily driving. The wheelbase on both vehicles is nearly identical, suggesting a similar level of high-speed stability.

Parking
Will the 2015 Tesla Model X or 2017 Tesla Model 3 fit in a standard parking space?
2015 Tesla Model X parking fit score
DriveSize compares the car's width and length with typical parking-space sizes by region.
Vehicle dimensions are rounded up and available side or length clearance is rounded down.
Side clearance is based on body width excluding mirrors where available; real spaces can vary because of mirrors, walls, pillars, kerbs, bay markings, and nearby cars.
For an average USA / Canada space: body side clearance is 37.5 cm per side (excluding mirrors), and length clearance is 22 cm at each end.
