2015 Tesla Model X dimensions & size guide

At 5052 mm long, 1999 mm wide (2271 mm including mirrors) and 1684 mm tall, the 2015 Tesla Model X sits firmly in the large SUV category. Its footprint gives it a commanding road presence while retaining the aerodynamic smoothness that defines Tesla’s styling. Head-on it looks clean and minimalist, the roofline sweeps gently towards the back, and the large glass windscreen which extends past the driver’s head provides exceptional visibility and a bright, airy cabin feel. The 2965 mm wheelbase offers generous interior space, while the 171 mm ground clearance gives it light off-road ability and easy access for passengers.

Underneath, the Model X shares the same electric platform as the Tesla Model S, with its battery pack integrated into the floor. This gives the SUV a low centre of gravity, improving stability and handling despite its larger size. Acceleration is instant and quiet, and while the Model X is built for practicality, its performance is still impressive. Its higher-spec versions could outpace a number of sports cars while carrying an entire family in comfort.

Inside, the Tesla Model X (2015) feels familiar yet distinct. The minimalist dashboard layout mirrors that of the Tesla Model S, dominated by a large central touchscreen that controls almost all vehicle functions. The wide, panoramic windscreen creates a unique sense of airyness, and the optional seven-seat configuration made it one of the few electric SUVs at the time to carry so many passengers. Materials are simple but solid, prioritising function over unnecessary complexity.

Practicality is where the Model X excels. With the seats in place, it offers 544 litres of cargo space, expanding to a huge 2486 litres with the rear rows folded. The rear load bay is flat and easy to access, while the additional front trunk (“frunk”) adds to its versatility. The 2015 Tesla Model X is designed to handle everything from school runs to long road trips, and its clever door system provides excellent access even in tight parking spaces.

The Falcon Wing doors are one of the Model X’s most distinctive features, and they’re more than just a design statement. They’re engineered with double hinges, allowing them to open upward and outward simultaneously, so they require less space beside the car than conventional doors which is great for parking spaces and garages (as long as they have a high enough roof!). They also give the Model X a futuristic personality, turning something as simple as getting in and out of a car into a small piece of theatre.

On the road, the Tesla Model X is smooth and composed. The adaptive air suspension adjusts automatically for comfort and efficiency, and the steering feels light yet precise. With a 12.3-metre turning circle, it’s surprisingly manageable for its size. The silence of the electric drivetrain enhances refinement, and with instant torque, it feels effortless to drive in any setting.

The first gen Tesla Model X was more than just a larger Tesla, it was proof that electric vehicles could deliver practicality and performance in equal measure. It took the innovation of the Tesla Model S and reimagined it for families, creating one of the first luxury electric SUVs that truly worked as an everyday car.
