Why is the wheel cover suitable for the Tesla Model 3?
Tesla Model 3, the upgraded version of the 2019 standard battery life rear drive, comes with a set of plastic hubcaps. After reading the comments from netizens, it has received rave reviews. Some say that it looks a lot more handsome after adding it.
The actual measurement results from the American automotive media CarandDriver: They found that the hubcap of Tesla Model 3 has an energy-saving effect. Under the conditions of 6 degrees above zero and 2.8bar tire pressure, the test speed is 80, 113 and 145km/h with and without the cover. Covered Model 3 vehicle range. The results show that the energy consumption of a 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 increased to 320 km).
With the hub cover, it can be reduced by 2.5%~4.5%, which can be said to be a very big improvement. You must know that even if it is only 3% energy saving on a fuel vehicle, engineers spend a lot of human and financial resources. It may not be possible to achieve it.
Can the proper shape of the hubcap reduce fuel consumption? The answer is yes. The famous car critic YYP answered the questions of netizens in his program "ASK YYP". The original words at that time were: Can the shape of the wheel hub of the car be made into a suitable shape to satisfy the aerodynamics , thereby reducing fuel consumption? Why haven't mass-produced cars taken this step yet?
On the one hand, the wind resistance coefficient of each car is different. If it is mass-produced, the wheel parameters of each car need to be redesigned, which is not suitable for mass production and the common degree of sharing of models. On the other hand, it will also significantly increase the production cost. For a family car that is reluctant to give more reversing lights, it is impossible and necessary for them to do this.
Why doesn't Tesla Model 3 directly produce aluminum alloy wheel shapes like hubcaps? This is for weight loss and cost reasons. The shape of the hubcap is also very important. The hubs on other brands of family cars do not reflect the shape of the hubcap. A comparison makes the texture and shape of the hubcap on the Modle3 significantly different from other brands of low-end models.
Tesla is defined as the Apple of the new energy industry. Many things it does are to refresh the inherent mode of the automotive industry, from 7,000 18650 batteries, to the large central control screen, to no physical buttons, to playing racing games with the steering wheel , to the dog mode and then to the recent smart call, plus the brand premium, all of which are rationalized. The same wheel cover has become a sweet pastry on the Tesla Model 3. These are the reasons; the new force of independent brand car building You have to refuel, don't just think about making new energy vehicles to market.
