According to the original plan, Li Auto would have launched three pure electric SUVs in a row this year, named M7, M8, and M9, but in the first half of this year, Li Xiang had officially announced that it would be postponed to 2025. The relatively big controversy has always been that it is designed like MEGA, but with the exposure of the latest road test spy photos of the pure electric SUV, this conclusion is about to change. Compared with the spy photos of the early 3 new cars in the same frame, although the specific identity of the exposed model cannot be directly determined, it can be determined that the ideal car has readjusted the tail shape, no longer following the unique tail style of MEGA, but returning to the traditional SUV tail box design, which means that the original third row of spacious headroom will most likely be compressed, as for whether the three-row seat layout will continue to be launched, this needs to be further confirmed by the official.
After all, as the first layout of Ideal Auto in the pure electric SUV market, it is highly competitive with competitors including Wenjie, and the product power needs to be on par with its own pure electric flagship, so what will be the specific performance of the new car? How much battery life is there? What about intelligent driving and driving quality?
The Kirin 5C battery continues to be on the car, and the entry range is more than 700 kilometers?
From the perspective of the owner, compared with the experience of pure fuel vehicles, there have always been two problems with pure electric vehicles, that is, there is anxiety about battery life and low energy replenishment efficiency, but from the perspective of battery technology, these two problems can actually be solved together at the same time, that is, to improve the battery charge and discharge rate, which has come out and is equipped with MEGA, Xiaomi SU7, and Krypton 009 Kirin 5C battery, which can effectively solve these two problems at present, so in the next ideal pure electric SUV, This battery is bound to be a "must-have" for a new car.
So, what is the approximate level of the range of the ideal pure electric SUV? To answer this question, it is necessary to first talk about some of the technical characteristics of the Kirin 5C battery, of which "5C" says that the battery charge and discharge rate is 5, that is, the charging current of the battery cell is divided by the multiple of the cell capacity is 5, the higher the multiple, the faster the charging speed, the shorter the time, and the lower the conversely, the slower, referring to the energy supplement performance of MEGA, it can be charged to 80% in 12 minutes, about 500 kilometers, so that the problem of going out is afraid of insufficient battery life and worrying about the charging time, which is basically solved.
That is to say, under the constant charging current of the battery, one of the ways to improve the charge and discharge rate of the battery is to increase the capacity of the battery, which means that the specifications of the battery will be larger, but the physical characteristics of the battery determine that the higher the energy density, the lower the charge and discharge capacity.
To put it simply, it is necessary to greatly improve the migration rate of lithium ions from the positive electrode to the negative electrode, which can also be understood as the process of lithium ions from point A to point B, shorten this process, you have to start from the distance, time and even materials, and finally in the test environment, the peak charging current of the Kirin 5C battery exceeds 700A, and the peak charging power reaches 520kW, in short, this battery shows two things, one is that the capacity specification will not be small, and the other is that the large battery also has a high charging and discharging capacity.
At this point, it can be basically judged that among the 3 pure electric SUVs pushed by Li Auto, the lowest positioning of the medium-sized SUV and the highest large SUV will be equipped with Kirin 5C battery, and with reference to the current mass production of the Extreme Krypton 009, Xiaomi SU7 and MEGA, it is estimated that the battery specifications of the new car are not small, the minimum will be 100kWh start, the pure electric mileage under CLTC working conditions, the probability will be more than 700 kilometers, if the vehicle can be further lightweight, Then it is possible to go even further with this endurance achievement.
When you see potholes, you will slow down in advance, and the driving quality is still comfortable?
Let's talk about some of the things that everyone is more concerned about, what can the ideal first pure electric SUV do in the intelligent driving part? What's the difference when you drive?
At present, the new generation of intelligent driving end-to-end + VLM of Li Auto has been pushed, specifically covering MEGA and L series AD Max models, from the effect point of view, the ideal set of high-end intelligent driving, there are many functions that are very similar to Huawei Qiankun ADS 3.0, such as starting on the roadside can directly start the intelligent driving function, no longer restricting the opening of the scene conditions, you can drive when you get in the car; In roundabouts or congested road conditions, the processing mechanism of the whole system is also relatively similar, and it can basically achieve autonomous and smooth lane changes to arterial roads with higher traffic efficiency; In addition, the intelligent driving system of Li Auto will also independently select the tidal lane according to the changes of real-time traffic lights, and even slow down in advance when seeing potholes, T-junctions or school sections, and the overall effect of the two systems is mainly efficient and human-like.
On the surface, the intelligent driving system of Li Auto and Huawei Qiankun ADS 3.0 are both end-to-end, getting rid of the dependence on high-precision maps, and the hardware is mainly based on cameras + radar sensors, but the underlying logic is slightly different, the latter's GOD+PDP can strengthen the perception of road details, while the former divides intelligent driving into three processing systems, that is, end-to-end + VLM + cloud world model.
The "end-to-end" is easy to understand, it is responsible for perception, decision-making and regulation of the three modules in the past, all integrated into a model, when the external sensor obtains information and after the model processing, it can more accurately and quickly control the system to make decisions, which is like the human eye in the acquisition of information, directly transmitted to the brain to continue analysis, and then the first time to make the corresponding behavior, compared with the previous need to manually knock out the code rules, the end-to-end advantage is to face the experience of what has happened, In the face of what has not happened, it will learn to deal with it, which is an active learning process, so this is also the mainstream direction of the development of the intelligent driving industry at present and for a long time in the future.
We have analyzed before,The problem that needs to be solved after Tesla's FSD enters China,How to deal with the sudden appearance of battery cars,This is actually a scene that the intelligent driving system has not seen,A large number of measured videos are required for long-term training and analysis,After all, it is necessary to cover all emergencies on the road,FSD's training in China will be a protracted battle,Huawei's Qiankun ADS 3.0The solution given is to use 4D millimeter-wave radar,Monitor small targets around the clock,GOD+PDP can strengthen the perception of road details, The advantage is that it directly avoids the massive data training of unknown scenes, and Li Auto handed over this part to VLM, the overall algorithm is composed of a model, and also includes a streaming video converter, intelligent driving memory and problem library, which can cache data for a longer period of time in order to think and learn logical reasoning, to put it bluntly, the role is to encounter a scene that the intelligent driving system has never seen, VLM will give corresponding feedback with its ability to learn, which is a bit like the meaning of the upgraded version of independent learning in end-to-end.
In addition to end-to-end and VLM, the cloud world model is more like a large "error bank", when the vehicle encounters driving problems, the world model can try to reconstruct the problem scene, analyze the root cause of the problem by big data, and then carry out targeted training, and then hand over to end-to-end processing after learning.
Back to the new body, if it is released in the first half of next year and can be delivered in the second half of the year, there are nearly 12 months left for end-to-end + VLM growth.
In addition, at present, the interior information of the ideal pure electric SUV has not been exposed, but with reference to the family design of the L series, it is expected that the interior of the new car will still provide two intelligent on-board screens for the main and co-driver, and the specific functions of the smart cabin are expected to be consistent with the L series, and continue to focus on home first.
At this point, about the performance of the driving level, we can basically give a judgment, the future ideal pure electric SUV driving experience, must also be towards comfort, so in the suspension configuration, the new car will most likely continue to use the L series has appeared front double wishbone rear five links, high-end models are expected to also provide CDC shock absorbers and dual-chamber air suspension, for positioning larger tonnage higher SUV, this kind of suspension layout can reduce body roll, filter fine vibration, so as to better ensure comfort and safety.
Finally, in fact, there is another question that we need to continue to explore in depth, that is, the ideal first pure electric SUV, starting from a medium-sized SUV, even if there is a Kirin 5C battery in the future to make up for the problems of battery life and energy supplement, but the large size and weight will have a direct impact on energy consumption, if the MEGA-style front can reduce wind resistance and optimize energy consumption, but what will be the extent of the lightweight of the vehicle? We'll see.
