The differences between the 2021 Tesla Model 3 and the 2020 Tesla Model 3 are: 1. Different power: The 2021 Tesla Model 3 is equipped with a pure electric 461-horsepower motor; the 2020 Tesla Model 3 is equipped with a pure electric 462-horsepower motor. 2. Different number of models: The 2021 Tesla Model 3 offers two models; the 2020 Tesla Model 3 offers four models. The Tesla Model 3 is a mid-size car under Tesla, with a length, width, and height of 4694mm, 1850mm, and 1443mm respectively, a wheelbase of 2875mm, and a body type of a 4-door, 5-seater sedan, matched with a single-speed transmission for electric vehicles.

I drove the 2020 Model 3 before switching to the 2021 version, and the most noticeable upgrade was the interior center console. The 2021 model doubled the center storage space and added dual wireless charging pads, allowing phones to charge just by placing them down, whereas the 2020 version required plugging in cables, which was much more cumbersome. The powered trunk is my favorite improvement—just press a button to open or close it when shopping in the rain. After switching to double-pane laminated glass for the windows, highway noise was reduced by at least 30%. However, the 2021 model replaced all USB-A ports with Type-C, forcing me to buy new cables. The heat pump AC reduces power consumption by about 15% compared to the 2020 model when heating in sub-zero temperatures, which is a hidden perk.

As someone with a technical R&D background, I see the 21st model upgrade focuses on core components. The heat pump air conditioning system replaces the 20th model's resistive heating, reducing energy consumption and making winter range more stable. After optimizing the battery management system, charging speed has increased by 7%. The body casting process has changed from 70 parts to 2 integrated components, increasing structural strength by 25%. The domestic 21st model also switched to CATL's lithium iron phosphate battery, which is lower cost and has a longer cycle life. The infotainment chip was upgraded from Atom to AMD Ryzen, increasing processing speed fivefold. However, the rear steering knuckle material changed from aluminum to steel, which is strong enough but slightly heavier.

For daily commuters, the 2021 model is recommended. The charging port position has been modified for better accessibility, and the trunk has been upgraded from manual to electric operation, making it much more convenient than the 2020 model. The center console buttons have been replaced with metal scroll wheels, significantly improving the tactile experience. The steering wheel heating function has become standard in the 2021 model, keeping your hands warm in winter. The seats now feature lumbar support adjustment, enhancing comfort during long drives. The front trunk space has been reduced by 10%, but the addition of drainage holes makes it easier to clean. The air vents have been redesigned into a hidden style, simplifying dust removal. The roof glass has been enlarged by 5%, providing a more expansive view.
