The side and back panels are generally made of synthetic leather, also known as PVC. Other parts use genuine leather. Below is an introduction to the Model Y 2021 model: 1. Body dimensions. The full series has a body length of 4750 mm, body width of 1921 mm, body height of 1624 mm, wheelbase of 2890 mm, front track of 1636 mm, rear track of 1636 mm, and it is a five-door, five-seater SUV model. 2. Configuration. The model features a front induction asynchronous motor and a rear permanent magnet synchronous motor. It adopts a dual-motor layout with the motors positioned at the front and rear. It uses a ternary lithium battery, with a battery warranty of eight years or 192,000 kilometers. Fast charging takes one hour, while slow charging takes ten hours.

















I've recently researched Tesla's seat materials and found they're now emphasizing eco-friendly concepts, largely avoiding genuine leather. The standard Model 3/Y uses a synthetic leather that feels like real leather but is actually artificial, being highly practical with water and stain resistance. The premium versions upgrade to higher-grade imitation leather, officially called 'ultra-fiber leather,' which features micro-pores for better breathability – no sweaty back during summer road trips. Interestingly, these materials all have anti-slip treatment to securely hold occupants during sharp turns. The supplier reportedly conducted accelerated aging tests to ensure no cracking or peeling even after five years.

As someone who pays attention to automotive craftsmanship, I've discovered that Tesla's seat materials actually incorporate cutting-edge technology. The mainstream models use vinyl artificial leather, which is more scratch-resistant than genuine leather—even keys won't leave marks. The most fascinating part is the special anti-UV coating applied to the seat surface, preventing hardening or stickiness after prolonged exposure to sunlight when parked outdoors. Material lab test data shows this synthetic material is about 30% lighter than genuine leather, contributing to overall vehicle weight reduction. When picking up your car, feel free to touch the back of the seats—they feature breathable mesh fabric panels to keep your back dry during long drives.

During the test drive, I specifically asked the salesperson, and no longer uses genuine animal leather in any of its models. The base model's artificial leather resembles lychee-patterned genuine leather but is actually made of polyurethane synthetic material, which can be easily cleaned with a cloth. The optional white interior features custom synthetic leather with an added anti-stain coating, so you don't have to worry about color transfer from jeans. One thing to note is to be careful with the rear seats to avoid scratches from the metal parts of the safety buckles—while the material is wear-resistant, sharp objects can still cause damage. For maintenance, simply wipe with a neutral cleaner, and avoid using leather conditioning oils as they can corrode the surface.

From the teardown video, the seat structure consists of three layers of surface material: the outermost layer is an ultra-fiber base with a wear-resistant coating, the middle layer is high-elasticity foam, and the bottom layer has moisture-proof fabric. This composite material doesn't get as cold as genuine leather in winter, nor does it get uncomfortably hot against the legs in summer. Actual tests show its heat dissipation is 40% faster than Nappa leather, preventing body slippage during aggressive driving. The factory conducted cold resistance tests on the material, confirming it won't become brittle even at -20°C. If there's a drawback, it might be the lack of genuine leather's natural grain texture, but its eco-friendliness truly surpasses traditional luxury cars.

From a materials science perspective, Tesla's synthetic leather outperforms traditional genuine leather in durability. It utilizes an ultra-fine fiber base layer with a polymer coating on the surface - coffee or soda spills can be wiped off without leaving stains. I've tested the tensile strength of the seat surface, which can withstand 200kg of pulling force in both lateral and longitudinal directions without deformation. Interestingly, the seat edges feature reinforced thickness - the most wear-prone areas from frequent entry/exit are specifically thickened by 0.5mm. When a used car, pay special attention to this area; if it shows no wear, it generally indicates the previous owner maintained the vehicle with great care.
