2021 Tesla Model X dimensions & size guide

At 5060 mm long, 1999 mm wide (2271 mm including mirrors) and 1680 mm tall, you can see that the 2021 Tesla Model X has roughly the same footprint as the 2015 version using our Tesla Model X 2015 vs Tesla Model X 2021 size comparison tool but it looks sleeker and more cohesive. The styling refresh introduced cleaner surfaces and subtler detailing, giving the SUV a smoother, more aerodynamic appearance. With a 2965 mm wheelbase, there’s still plenty of space inside, while the lower 146 mm ground clearance improves efficiency and road stability. Despite weighing 2373 kg, the Model X hides its mass remarkably well thanks to its low centre of gravity and instant electric torque.

The most dramatic changes are found inside. The Tesla Model X (2021) received a completely redesigned cabin, bringing it in line with the Tesla 2021 Model S. A new horizontal touchscreen replaced the earlier vertical layout, improving visibility and usability. The introduction of the yoke-style steering controller added a futuristic touch, while the panoramic windscreen (still one of the largest in any production car) continues to make the cabin feel light and spacious. Materials and fit have also improved, with higher-quality finishes that move the Model X closer to traditional premium rivals.

Practicality has always been a core strength, and this update made the Model X even more capable. Cargo space now measures 1233 litres (VDA) with all seats in place and expands to a massive 2593 litres when folded, making it easily among the best in its class. The flat loading floor and wide opening make it simple to fit everything from luggage to bicycles, and the front trunk (“frunk”) provides even more storage. The 2021 Tesla Model X remains one of the few electric SUVs that can genuinely replace a large family car without compromise.

Of course, the signature Falcon Wing doors made a return. Their unique dual-hinge design allows them to open gracefully even in tight spaces, providing easy access to the rear seats and retaining the theatrical touch that’s become part of the Model X’s identity. Despite their complexity, they remain a practical solution for loading passengers and child seats in confined parking spots.

On the road, the Tesla Model X (2021) feels both powerful and polished. The dual- and tri-motor configurations deliver breathtaking acceleration when in Plaid form, it can match the speed of many supercars. Yet it remains calm and composed, with the adaptive air suspension continuously adjusting for comfort and control. Steering precision and ride quality are improved compared with the earlier version, making long journeys quiet and relaxing.

Tesla’s latest infotainment and driver-assistance systems also feature here, including improved Autopilot capabilities and faster hardware. Wireless updates continue to keep the car’s software current, ensuring owners benefit from ongoing improvements without visiting a dealership.

The 2021 Tesla Model X shows just how far Tesla’s SUV has come since the first model, take a look at our 2025 Tesla Size Guide to see this explained. It takes the versatility of the original and combines it with cutting-edge technology, refined comfort, and performance that feels almost effortless. For drivers who want space, power, and innovation in one striking package, it remains one of the most distinctive electric SUVs on the market.
