At the acceleration level of three to four seconds per hundred kilometers for electric vehicles, people seem to scoff at the acceleration performance of traditional gasoline vehicles, especially among ordinary car consumers. People often use the acceleration of new energy vehicles to “humiliate” those high-performance cars.
For electric vehicles, if the battery is sufficient, the time it takes to accelerate for four seconds from 100 kilometers is considered normal. But for internal combustion engines, four seconds is obviously not something that ordinary family cars can do. Taking mass-produced gasoline cars as an example, this acceleration level usually needs to be above 350 horsepower, while ordinary family cars can only maintain a horsepower of 250 horsepower even if they are 2.0T, which is considered sufficient power reserves.
In the electric vehicle industry, we can buy Tesla’s Model 3 Performance, which has good acceleration performance. It is equipped with a dual motor all wheel drive power layout, with a comprehensive output power of 485 horsepower, an acceleration of 3.3 seconds per 100 kilometers, and a CLTC range of 675 kilometers. It can be said that the data is very beautiful. If gasoline cars reach such a level, it would be a supercar.
Why does an electric vehicle accelerate so fast? Many people will raise such questions. Here, let’s briefly popularize the science that the output characteristics of electric motors are completely different from those of internal combustion engines. We all know that in order for an internal combustion engine to achieve maximum torque, there must be a process of speed climb. Only at the maximum torque speed platform can the maximum torque be output, and in this case can the fastest acceleration be completed. For an electric motor, as long as the current and voltage are stable, the motor can output maximum torque at the moment you press the “accelerator” to the bottom. This difference is the biggest reason why the acceleration performance of the two is completely different.
Secondly, from the perspective of energy conversion, analyzing the problem requires that the electric energy required for electric vehicle motor rotation comes directly from the battery, while gasoline vehicles need to transport the gasoline in the fuel tank to the combustion chamber of the engine through an oil pipeline, mix it with air, atomize, ignite, and produce an explosion in order to drive the piston to operate. The operation from gasoline to the piston requires time, and the current flows through wires, The time loss in between can be said to be negligible. Electric vehicles have unparalleled advantages in terms of time and energy conversion compared to gasoline vehicles, so it is understandable that electric vehicles accelerate quickly.
But one thing is that electric vehicles also have a prerequisite for fast acceleration, which is that they must have sufficient battery power. If the battery itself is low, after continuous acceleration, the acceleration of electric vehicles will only slow down, while gasoline vehicles obviously do not have this problem.
Is that why people who pursue speed tend to buy electric cars? The answer is no, although electric vehicles are fast, they lack emotions and communication between people and cars, which is also what many gasoline enthusiasts insist on. But it is undeniable that the market for gasoline cars that pursue performance is constantly shrinking, so even though electric cars are fast, they still cannot replace the position of gasoline cars in the hearts of many people.
