2021 Tesla Model S dimensions & size guide

At 5021 mm long, 1987 mm wide (2189 mm including mirrors), and 1431 mm tall, you can see that the 2021 Tesla Model S is slightly larger than its predecessors in our Tesla Model S 2016 vs Tesla Model S 2021 size comparison. The sleek design refresh introduced an even cleaner front end, reshaped bumpers and subtle aerodynamic tweaks that help it achieve remarkable efficiency for a luxury saloon of its size. The 2960 mm wheelbase carries over, maintaining the same spacious interior, and the 117 mm ground clearance keeps the car low and stable on the road.

Tesla’s approach to engineering continues to focus on simplicity and innovation. The battery remains integrated within the floor, giving the car a low centre of gravity that enhances stability and handling. The 2068 kg curb weight (32 kg heavier than the second generation) might sound heavy, but the instant torque of its electric motors ensures the third generation Tesla Model S accelerates with effortless power. Depending on specification, it can reach 0–100 km/h in under two seconds, figures that place it firmly in performance car territory.

Inside, the 2021 update brought the most dramatic transformation. The cabin layout was completely overhauled with a horizontal touchscreen replacing the previous vertical display, creating a cleaner and more open feel. The controversial yoke-style steering controller made its debut here too, giving the interior a futuristic, almost concept-car look. The materials are more refined than previous generations, and the minimalist design feels warmer and more premium without losing Tesla’s signature simplicity.

Comfort and practicality remain strong points. With five seats and four doors, the Tesla Model S (2021) functions just as well as a daily family car as it does a long-distance cruiser. Cargo space remains impressive: 798 litres with the seats up and up to 1828 litres when folded. The combination of a rear boot and front “frunk” adds versatility that few performance cars can match. Whether it’s luggage, sports equipment or a week’s worth of shopping, the Model S handles it all with ease.

Driving dynamics are another area where the 2021 update stands out. The adaptive air suspension automatically adjusts ride height for comfort or efficiency, while the car’s low-slung design keeps it composed even under hard acceleration. The steering is precise, the brakes strong, and the silence of the drivetrain makes every journey feel smooth and unhurried. The Tesla Model S (2021) strikes a balance between blistering performance and day-to-day usability that few other cars, electric or otherwise, can match.

This generation also saw the introduction of Tesla’s latest software systems, with improved infotainment, faster processing and expanded driver-assistance capabilities. As with earlier models, updates can be installed automatically, keeping the car current without ever visiting a workshop.

The 2021 Tesla Model S represents Tesla at its most confident by blending advanced technology, luxury and astonishing performance into one sleek package. It’s the car that shows just how far the Model S has come since 2012, evolving from a bold experiment into one of the most complete electric vehicles ever built.
