Wenjie's new M7 five-seater is only a one-year facelift, but Yu Chengdong said that 500 million yuan has been invested in this facelift. Just by looking at the name of the model in the manufacturer's promotional materials, it can be seen that the "six-seater" and "zero-gravity seat" advertised by the previous model have been replaced by "large five-seater" this time. It can be seen that this product has seriously learned from past experience and made some adjustments in the direction of product definition. In addition to the improvements we think a facelift should have, the new car has a lot of targeted improvements and changes. This article is dedicated to you in detail.
【·1·Active and passive safety improvement】
The renovation invested 500 million yuan, of which 280 million yuan was used for safety improvements. The cage body consists of 24.4% high-cost high-strength hot-stamping steel. Used in places closely related to the safety of the crew compartment, such as the A-pillar. The whole car is made of high-strength and rigid materials, and aluminum alloy accounts for 80.6%. Interior of the beam also adds sill frames and horizontal and vertical beam structures. The battery has double anti-collision beams. In terms of active safety, AEB active braking speed has been improved, and side collision avoidance, low-speed collision avoidance, ghost detection, etc. have been optimized.
【·2·Design and configuration】
In terms of exterior design, the whole vehicle has not changed much. The front dashboard and fog light area have changed, so one can tell that this is a new M7. The most obvious of the intelligent driving version is, of course, the camera modules on the wings on both sides of the front and the lidar on the roof.
The center console in the car has been replaced with a flocked wrap, and the refinement has been improved. The steering wheel adopts the same color design as the interior, which feels that the structure is poor, but the material of the steering wheel has not changed significantly, and the touch is still hard and lacks luxury. The car's system has been upgraded to the Harmony 3 system, which supports the transmission function of mobile map and food application, the automatic adjustment function of HUD eye position and rearview mirror, and the interaction of multiple Maglink screens in the rear. You can use the second-row PAD through accessories. Controls the connection to the end of the vehicle. In response to the problem that the rear air conditioner of the old model cannot be heated, the new model has added an air conditioning box, which is specifically responsible for the cooling and heating of the rear air conditioner. There are 17 air conditioning outlets in the whole vehicle.
【·3・Space Game】
In terms of space, the biggest change is the layout of the big five seats. The entire car seat has been redesigned, and the foam material has been significantly strengthened and softened, which significantly improves driving comfort. The height angle of the second row is significantly increased, the seats are longer, the feet are in place and the backrest is electrically adjustable. After the second row is reversed, it can form a connecting space with the luggage compartment. In combination with an inflatable mattress, it is possible to create a more comfortable place to rest in the car. The front seats can also be fully folded and combined with the second row of seats (headrests need to be removed, if the main driver chooses the audio headrest, the main driver folding is not supported).
In terms of chassis ride, in response to the previous chassis quality problems, the FSD variable damping shock absorber has been upgraded throughout the car, which can smooth subtle bumps during driving and reduce excessive suspension bounce when crossing trenches. The chassis texture has been improved compared to the old model. In addition, mechanisms such as the aluminum lower wishbone and aluminum steering knuckle also reduce unsprung mass to a certain extent, helping to improve handling. Huawei's DATS has been upgraded to 2.0 to optimize torque control logic and improve four-wheel drive stability. Overall, the chassis quality of the facelifted M7 has indeed been optimized. Compared to the ideal L7 chassis, the chassis is stiffer and more integrated. However, due to the cab shape and suspension structure, chassis control performance is slightly lower than that of the M5.
【·4· The incidence of NCA in urban areas has not been shown.
Regarding the NCA of cities, this time we received news that the progress of NCAs in cities without high-precision maps has accelerated. By the end of the year, mapless NCAs will be rolled out nationwide, regardless of city.
This time, I would like to briefly report on the NCA's performance in non-depicted urban areas that I experienced in Shanghai.
First of all, let's talk about the problem: the road conditions without maps in the country are extremely complicated in the NCA, and many special roads it still cannot handle. For example, it is impossible to recognize the signal lights of the closed lane in the tunnel, the text prompt such as the text prompt in the straight waiting area, the bus lane, the tidal lane, etc. cannot be recognized; When faced with temporary maintenance roads, stops can be accurately identified, but detours are not possible. Good; Still unable to identify lower road obstacles and unresponsive when surrounded by a car that appears to have fallen onto the road; At some intersections, she was pushed out for no reason; Traffic light countdown delays are visually slightly longer than before. At present, the road information in the SR interface is completely based on the recognition of the vehicle body perception system, including traffic light countdown information. Previously, it was detected that the three-digit signal light could not be recognized, but this time it was not optimized, and the SR interface signal light was still in two digits.
Therefore, when faced with some special situations on the road, as a consumer, you need to pay attention and be ready to correct the wrong behavior of the vehicle. After all, current regulations don't allow self-driving cars on the road yet. According to the assumption of assisted driving, in the event of an accident, the human driver is still responsible.
On the route of our experience, its intelligent driving is not much different from the version with a high-precision map, apart from the problems mentioned above. It is a big improvement over the version of NCA cities with high-precision maps that I experienced three months ago.
Progress is reflected in:
1. The efficiency of left turn without protection is greatly improved. There is no stopping and waiting in all left and right turn situations, and the left and right turns are smoother than the previous version.
2. The left turn waiting area is recognizable. I don't know if it was an accident, when I went straight at the green light, turned left at the red light, there was a waiting room, there was no vehicle in front, and the M7 intelligent driving version successfully stopped at the intersection first. Waiting room. The engineer explained that it was a vehicle-mounted map with information about the waiting area at that intersection. Because the waiting area has a certain angle, it will not be perceived by the vehicle-side sensing hardware.
3. Can identify yellow light. When the signal light is clearly yellow, the car has not taken any slowing action, but passes the yellow light at a constant speed. There are two possibilities for this result. First, the car accurately calculates its own speed and the distance to the stop line, and combines the time when the yellow light appears to calculate whether it can pass the stop line before the red light. Another possibility is to identify that there is a delay in the car's signal lights. When the car detects a yellow light, the car has already passed the station.
4. Continuous lane change at intersections is smoother. It can achieve a one-time lane change of multiple consecutive lanes in front of a traffic light. The process is similar to that of a human driver, without changing the machine lane segmentation.
【·Write at the end·】
After this test drive of the world's new M7 five-seater, it is the first time to see such a big change in a one-year facelift. On the one hand, it shows that the old M7 still has some shortcomings after all. The official has also been criticized by users and the media. The change was very targeted and honest. On the other hand, combined with the pre-sale price of the new car from 258,000 yuan (30,000 yuan lower than the entry price of the old model), it shows that Huawei and Wenjie have high expectations for this M7, and the new car must carry a higher sales target. In this year's competitive market, Huawei urgently needs to seize its own market share, and Wenjie's performance also sets an example for companies that cooperate with Huawei. Therefore, the Wenjie brand is the "Jingzhou" of Huawei's automotive business. If it gains a foothold in the market, it can advance, retreat, and defend. Otherwise, it will have a profound negative impact on the future development of the enterprise.
At present, the ideal L7 is on the market, deeply rooted in the hearts of the people, and receives a large number of orders every month. Later, there is also the newcomer Lynk & Co 08, which adopts a new design language, is equipped with high-end Lynk & Co resources, and Meizu car machines supported by technology manufacturers, which should not be underestimated. Market competition will continue to intensify. Who is the winner in the 200,000 yuan smart car market, maybe by this time next year there will be a clear answer.
