Do you think Tesla's battery life is not good? You might be able to change the wheels
As a kind of new energy vehicles, electric vehicles have the advantages of quiet driving, no pollution, and convenient supply. At present, the more mainstream electric vehicles are Tesla Model 3, Tesla Model Y and so on. Of course, Tesla still has some imperfections. For the majority of drivers, Tesla's battery life often makes them feel less secure. So what are the unknowns that affect Tesla's battery life? You might not think of this - the wheels.
Recently, foreign blogger Tesla Canuck conducted an experiment on the impact of different wheel hubs on the battery life of electric vehicles. The models he tested were Tesla Model Y, and they were all 2021 long-range versions. The only difference is that the white model is equipped with 19-inch Gemini wheels, and the black model is equipped with 20-inch induction turbo wheels. During the test, the local temperature was 16 degrees Celsius, and the Tesla Canuck deliberately controlled the two cars to drive the same mileage at the same speed.

Tesla Model Y white (with 19-inch Gemini wheels)
After testing the results, Tesla Canuck was surprised to find that the white model with 19-inch wheels was significantly more energy efficient than the black model with 20-inch wheels. According to calculations, the average energy consumption of the 19-inch Gemini wheel is 17kWh/100km, and the average energy consumption of the 20-inch induction turbo wheel is 18.4kWh/100km, a difference of about 8%. It seems that different wheel hubs still have a certain impact on the battery life of Tesla models, and the majority of drivers can pay attention.
The actual measurement results from the American automotive media CarandDriver: They found that the Tesla Model 3's wheel caps have energy-saving effects. Under the conditions of 6 degrees above zero and 2.8bar tire pressure, the test speeds were 80, 113 and 145km/h with and without the cover. of Model 3 vehicles. The results show that the energy consumption of the covered vehicle is reduced by 3.1% at 80km/h (from 502 to 518km), by 2.5% at 133km/h (from 407 to 418km), and by 4.5% at 145km/h (from 306 Raised to 320 km.
When the car travels at a speed of 80 kilometers per hour, about 60% of the total energy consumption is used to overcome air resistance. Therefore, major car companies are working hard to reduce the drag coefficient of cars. The drag coefficient of Tesla model 3 is as low as Cd.022, which is quite excellent. In addition to adding wheel covers, Tesla also pioneered the use of hidden door handles, which are also used to reduce wind resistance and increase battery life.
