2021 Tesla Model S vs 2015 Tesla Model X
Which is bigger, the 2021 Tesla Model S or 2015 Tesla Model X?
Key dimensions: length, width, height
With a difference of just 3.1 cm in length, the 2021 Tesla Model S and the 2015 Tesla Model X can be judged practically the same for this measurement. There’s a marginal 1.2 cm width difference; the 2015 Tesla Model X is effectively the same width as the 2021 Tesla Model S for all practical purposes. The 2015 Tesla Model X is an incredible 25.4 cm taller, which fundamentally alters the ease of access and the total volume of the interior relative to the 2021 Tesla Model S. The 2015 Tesla Model X sits 5.4 cm higher off the ground than the 2021 Tesla Model S, providing a helpful extra margin of safety when driving over gravel or light debris. Both cars sit on nearly the same length wheelbase, with the 2015 Tesla Model X being just 0.5 cm longer than the 2021 Tesla Model S.

DriveSize space efficiency
DriveSize space efficiency compares blended cargo volume per square meter of footprint with the class average.
Blended cargo uses 65% of the standard figure and 35% of the largest figure within the selected cargo measurement method.
VDA values compare with VDA class averages, and SAE values compare with SAE class averages. Positive percentages indicate more space efficiency and negative percentages indicate less.

Doors, seats, weight, maneuverability
Choosing the 2015 Tesla Model X gains you extra access points, making its 5-door layout more versatile for daily duties than the 4-door 2021 Tesla Model S. The 2015 Tesla Model X can handle 2 additional passengers than the 2021 Tesla Model S, which is a decent step up in practicality. You won't find an agility advantage in either of these models, as both have a turning circle 12.3 m.

Parking
Will the 2021 Tesla Model S or 2015 Tesla Model X fit in a standard parking space?
2021 Tesla Model S 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 38 cm per side, and length clearance is 23.5 cm at each end.
