The differences between the Tesla Model 3 and Model S mainly lie in body dimensions, motor types, and driving range. Here are the specific details: 1. Body Dimensions: The Tesla Model 3 measures 4694/1850/1443mm, with both front and rear track widths at 1580mm. The Model S measures 4979/1964/1445mm, with a front track width of 1662mm and a rear track width of 1700mm. 2. Motor Types and Driving Range: (1) The Model 3 Standard Range Rear-Wheel Drive Upgrade and Long Range Rear-Wheel Drive versions both feature a permanent magnet/synchronous rear-mounted single motor. The Standard Range version is equipped with an LFP (Lithium Iron Phosphate) battery pack from CATL, with an official range of 468km. The Long Range version uses a ternary lithium battery pack, offering an official range of up to 668km. Both versions have a maximum power output of 202 kW and a maximum torque of 404 Nm. (2) The two lower-end Model S versions feature dual motors—front permanent magnet/synchronous and rear AC/induction—also powered by ternary lithium battery packs. The Long Range Upgrade version delivers a maximum power of 487 kW and a maximum torque of 844 Nm, with an official range of up to 719km.
When it comes to the differences between the 2017 and 2019 Tesla Model S, as a car enthusiast who enjoys delving into automotive technology, I believe hardware improvements are the most significant. The 2019 model introduced a permanent magnet front motor, which is more efficient than the 2017 model's induction motor, significantly boosting range—for example, easily exceeding 370 miles on a full charge compared to the older model's 330 miles. The suspension was also upgraded, with an optional adaptive air suspension for a smoother and more comfortable ride. On the software side, the 2019 model comes with Autopilot Hardware 3.0, capable of handling more advanced driver-assistance features with quicker responses. The battery management system was optimized, offering faster charging speeds and improved durability. These changes make the 2019 model more reliable for long-distance travel. If you're considering buying a used car, I'd recommend prioritizing the 2019 model for its tangible hardware upgrades. Of course, the 2019 model might be slightly more expensive, but it offers better long-term value.
