The curb weight of the Model 3 is about 1,600 kg to about 1,850 kg (varying with the number of drive motors and battery capacity, and differences in destination locations and vehicle grade). To improve energy costs, or rather to improve range, Tesla has endeavored to reduce the weight of both the chassis and the body while ensuring safety, running stability, and comfort. Similar to the high-grade Model S and Model X, the Model 3 has been packaged to an approximate 50:50 weight distribution ratio, varying from about 48:52 to 50:50 depending on battery capacity and drive type options.

With regards to running stability, the moment of inertia is suppressed by locating the battery in the underbody and placing large components such as heavy drive motors near the center of gravity at the axles. In terms of safety, based on the safety testing requirements of the National Highway Traffic Safety Commission (NHTSA), the Model 3 has received NHTSA’s highest (5 star) approval rating, similar to the Tesla high-end Model S and Model X, with a construction that ensures minimal injury in the event of a collision. The Model X SUV was developed based on the previous sedan, the Model S, but the Model 3 has been newly designed from stem to stern. The characteristics of the Model 3 chassis and body are safety and running stability, as well as weight reduction to improve the cost of electricity. This report introduces the features of the main parts of the chassis and body for the Model 3, which is Tesla’s main model, as revealed by the Munro teardown analysis.
