Recently, there have been many videos of high-horsepower electric vehicles on famous tracks and even training grounds, driving school vehicles losing control, and there are even dangerous incidents of high-horsepower electric vehicles crashing or overturning on the track or road.
In fact, fundamentally, high-horsepower electric vehicles are not suitable for the track.
But why are there so many high-powered electric cars making trouble on the track?
This starts with the beginning of the high-horsepower electric car, that is, the Tesla Model S P100D, which was mass-produced in North America and sold around the world.
The car is equipped with two electric motors, one in the front and one in the rear, and the four-wheel drive four-way brings the ultimate driving experience of more than 900 horsepower, of which the available battery capacity on the body is not deflated, and even the subsequent Plaid version of the model is undoubtedly standard with 1020 horsepower.
And the price of this car is only about 2 million, compared with other supercars with more than 1,000 horses, the cost performance is directly exploded, so for a while, many owners of electric vehicles in the pit want to enter a supercar-level electric car to play.
In recent years, with the increasing activity of the domestic pure electric performance car market, various car companies have also launched their own distinctive high-horsepower models, and the price is relatively cheap.
Power & Handling.
In terms of power, the power of domestic high-horsepower pure electric performance models can surpass some traditional supercars, although the traditional Moore engine will not be timid because of the 1500 hp motor, but at least the vast majority of intermediate sports cars on the market can be comparable to the power performance of traditional supercars.
This has undoubtedly made many fans interested in electric vehicles, after all, at the same 1500 horsepower, electric vehicles often have a peak torque of more than 3000 Nm, and the starting torque can reach 2,000 Nm, and these high torques do not need to rev very high engine speeds, but can be achieved from idling.
Therefore, compared with those models that are powered to go to high rpm horsepower and rely on braking, the power performance of pure electric vehicles is undoubtedly more straightforward, provided that the motor is durable.
In terms of handling, there is not much difference between traditional performance cars and electric performance cars in terms of handling performance, because domestic high-horsepower electric vehicles will adjust the hardness of the body during development, and the evolution of four-wheel suspension is very strong, and many vehicles have even achieved the ultimate in lateral support.
At the same time, due to the low center of gravity of electric vehicles, and in terms of battery packs, the battery is also divided into many small pieces and thrown into the car and then neutralized, so that the front and rear weight distribution is more reasonable, which undoubtedly makes the electric vehicle have a huge improvement in the stability of turning and driving.
For owners accustomed to driving a petrol sports car, a "battery" car with a very low center of gravity can give them a complete free run when cornering, so many owners will be amused by the excellent handling performance of the electric car after their first test drive.
But under this, there are still some models in the handling of the immature, especially in the case of extreme control, this is also because these car companies in order to save costs did not carry out too much "teasing" of the car performance, if you really want to go on the track, you need the owner to have a certain understanding of the tuning of the chassis.
Once the domestic electric four-wheel drive configuration of the pure electric vehicle on the track, there will often be an out-of-car incident, that is, the vehicle suddenly loses control in the process of advancing, the direction of wheel slippage cannot be controlled, and the cornering body is extremely unstable, which eventually leads to a rollover accident.
This is all because the weight of domestic pure electric four-wheel drive vehicles is relatively large, and the load on the braking system will be particularly large when the acceleration and deceleration are connected on the track.
In daily driving, you can accelerate with one foot when you want to fuel the temporary acceleration, but on the track, if you want to experience the real high-horsepower power, then the one-foot control cannot meet the "oil farming" acceleration, so you can only operate with two feet, one foot on the accelerator, and the other foot on the brake and one slow.
Track driving vs. everyday driving.
However, many car owners do not realize that the braking is often to make the car more stable when turning or passing through corners at high speeds, so they will not press it particularly carefully, especially when slowing down, many car owners will be more likely to ignore the pull caused by the brakes.
When the speed is reduced to a certain extent, after the speed of the car slows down, the hand releases the brake and the foot is pressed together, and the load on the brake system will be instantaneous.
Once the brake system of a high-horsepower pure electric vehicle slows down, the load cannot be put on, and it will lose control instantly, resulting in the front wheels sliding, the rear wheels unable to keep up with the acceleration wheel slipping, the body twisting direction cannot be controlled, and even the side slip overturn.
In this case, the anti-lock braking control of the braking system is no different from chicken ribs, and the car will slide in a straight line according to the direction of the front wheel skidding, and it is very likely to rush off the track or even overturn the accident.
No domestic car company will provide braking equipment for its performance cars on the track, so these braking systems are designed for daily driving and can complete most of the braking work in daily driving.
Therefore, the owner should always be vigilant when driving, because once the brake is needed in an emergency, the failure or loss of control of the braking system will directly threaten the life safety of the owner.
It is true that the danger of domestic high-horsepower models is also limited, after all, domestic car companies are still very solid in terms of safety, so in the event of an accident such as a rollover, the body structure will help the owner to suffer a showdown as much as possible, so the owner does not have to worry too much.
However, it is important to know that the safety mechanism activated by the vehicle is higher than the ceiling of the body itself, and it may also be misjudged to a certain extent, which is prone to the vehicle skidding and rollovering, but due to the control of the electronic stability system on the vehicle, the vehicle will automatically judge to let the front wheels slip to stabilize the body, but this will only make the side front wheels of the vehicle slip.
In addition, the sideslip impedance is increased due to sideslip when the vehicle rolls over, thus protecting the body structure, but this means that the vehicle is more likely to sideslip and hit the wall, putting the cabin at great risk.
Therefore, in order to ensure the safety of yourself and others, it is best to find a performance car when you get off the track, and it is recommended to make the necessary adjustments and preparations for these cars before using them on the track.
Once a high-horsepower pure electric performance car has a big accident on the track, it will only be more inconvenient for the follow-up car owners and the car community, so it is indeed a very dangerous thing to drive a "high-horsepower" pure electric car on the track.
What is the use of high horsepower.
So what should we think of these high-horsepower pure electric performance cars?
First of all, although these high-powered cars can also give us a good driving experience, this is not all they can offer, and the experience they show is only part of it.
Therefore, car owners should learn to stop in moderation when enjoying the driving process, and not too intense driving experience, otherwise it is easy for the external environment to change and cannot be synchronized with it, resulting in accidents.
Secondly, high-horsepower pure electric performance cars can also bring the speed experience of daily driving, which is also very practical for many owners of daily harsh driving environments, especially many drivers who will encounter extreme driving every day, and a high-horsepower performance car may make them "converge" a little.
At the same time, we also found that among the high-horsepower pure electric models, millions of models have been equipped with the world's top performance braking system, so those tens of millions of pure electric performance sports cars can achieve a real supercar-level experience, and can also better play the performance on the track.
However, such a braking system is also for track users, if it is just pure daily use, I am afraid it will attract a lot of unnecessary trouble, so in use or according to their own car needs to choose the model.
Don't think that this is a performance car just because it has that little bit of performance, you must know that a good performance car never has more than one dimension, but covers every detail of the vehicle's performance.
Therefore, if domestic car companies want to lead in the field of pure electric vehicles, they must also make a performance car in the real sense, rather than simply using a poor acceleration car, and must go to a higher level in the tuning of handling, braking, chassis and other aspects.
How to achieve such a performance car in an electric vehicle, it is necessary to start with light weight, because this is the most important condition for the car to be able to exert its performance.
In terms of lightweight, car companies can start by introducing more lightweight materials, and at the same time, they can also reduce the overall weight of the vehicle by reducing the capacity of the battery pack, so as to improve the handling performance of the vehicle.
In addition, in the future, domestic electric vehicles are expected to launch performance versions and track versions that are more suitable for the track, which will greatly improve the experience of domestic electric racing cars.
At the same time, in daily use, it can also better reflect the performance of the model.
epilogue
Domestic car companies also need to increase investment in these models, so that domestic electric vehicles can have better performance from the upgrading of technology and products.
But while enjoying the experience, car owners should also know that driving on the track and driving on the road are two different things, in order not to endanger the safety of their own lives and the lives of others, owners who are not racing drivers should not drive in the way of racing drivers.
