2021 Tesla Model X vs 2015 Tesla Model X
Which is bigger, the 2021 Tesla Model X or 2015 Tesla Model X?
Key dimensions: length, width, height
The 2015 Tesla Model X comes in only 0.5 cm shorter than 2021 Tesla Model X, meaning they're very comparable in length. Body width is exactly the same for both vehicles, with each measuring 199.9 cm. On paper, the 2015 Tesla Model X is taller by 0.4 cm, but just to look at, they appear essentially the same height. Sitting with 2.5 cm higher ground clearance, the 2015 Tesla Model X is better prepared for those unexpected potholes than the 2021 Tesla Model X. Wheelbase length is identical between the 2015 Tesla Model X and the 2021 Tesla Model X, so both should deliver a similar driving feel.

Parking
Will the 2021 Tesla Model X or 2015 Tesla Model X fit in a standard parking space?
2021 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 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, and length clearance is 22 cm at each end.
