The chassis technology of domestic new energy vehicles, especially mid-to-high-end new energy vehicles, is already beyond the reach of many century-old car companies. It is not because of how advanced the mechanical structure is, but because many ideas are not thought of in that direction by foreigners at all...

I don't know if you have noticed that with the continuous development of domestic new energy vehicles, the chassis technology of domestic new energy vehicles has also made significant progress, at least on paper. We see that many new energy vehicles of 200,000 or 300,000 yuan are equipped with air suspension and CDC variable electromagnetic suspension, and some models are equipped with compass turning and rear-wheel steering. Even million-level models like Yangwang U8 and Yangwang U9 can achieve emergency floating, fast jumping/flying in place and other actions. The feeling of driving and sitting in many new energy models is indeed "reborn"...

In the fuel vehicle market, the chassis performance of domestic vehicles is quite poor, and many users and professionals look down on it. So why did it suddenly become better in the era of new energy vehicles?

In the fuel vehicle market, the engines and gearboxes of most automobile products are located in the front cabin of the vehicle, so from a physical structure point of view, the front and rear weight distribution is unbalanced. Some models have achieved a balanced front and rear ratio, but the cost may be that the vehicle space and ride comfort need to be compromised. For domestic fuel vehicles that lack chassis tuning, the situation is even more difficult.

However, in the era of new energy vehicles, batteries play an important role. Now, except for some oil-to-electric models, the battery packs of most new energy vehicles are laid flat on the chassis. In this way, the front and rear weight distribution of the vehicle is actually very easy to achieve, and the battery is laid flat on the chassis, which can also effectively lower the center of gravity of the vehicle. From this point of view, at least from a structural point of view, it has an advantage.

More room for the front cabin

For the suspension, the more connecting rods connecting the wheels, the more precise the control of the wheels. In the era of fuel vehicles, since the engine and gearbox occupy a large space in the front cabin, it is actually not so handy to arrange the suspension system!

However, when it comes to new energy vehicle products, whether it is hybrid, extended range or pure electric, the front cabin space is relatively more abundant. In this case, there will be more space to arrange the double wishbone, multi-link and other front suspensions with relatively more complex structures, so that the chassis performance will be better.

High voltage electricity is also a kind of ability in itself

With the development of new energy vehicle technology, the suspension itself and the whole vehicle intelligence are also highly integrated, and the competition between automobile manufacturers has also made everyone more willing to "add ingredients" in terms of chassis! We have seen that many manufacturers have equipped new energy vehicles with air springs + CDC variable suspension, and the chassis height and suspension hardness are adjustable, which itself saves a lot of adjustment energy.

And the chassis system with extreme sports capabilities like Yangwang U9, equipped with linear motors, requires the blessing of high voltage electricity, which can make the suspended linear battery quickly burst torque and allow the vehicle chassis to be adjusted quickly, which is difficult to achieve in fuel vehicle products.

The battery increases the chassis's torsion resistance

As we said before, in new energy vehicle products, the way the battery is laid makes the battery a balance for the front and rear weight ratio of the vehicle. Now many vehicles are equipped with CTB and CTC battery-body integration technology, which not only makes the vehicle chassis more compact, but also makes the battery a part of the vehicle structure, making the vehicle's torsional rigidity stronger. With stronger torsional rigidity, the front and rear tracking of the vehicle is more obvious.

So in essence, as the domestic automobile industry enters the era of new energy vehicles, compared with fuel vehicles, it is not just the difference in the energy used by the vehicle, but a completely different set of ideas. So in fuel vehicles, what independent brands and domestic cars can't do well, new energy vehicles have the opportunity to do well, such as performance, chassis, intelligence, etc.
