Research on automotive smart exteriors: in the trend towards electrification and intelligence, which exteriors will be replaced by intelligence?
1. In 2030, China’s new energy passenger car exteriors market will be valued at more than RMB150 billion.
In the trend towards electrification and intelligence, the penetration rate of smart exteriors in passenger cars in China is on the rise. By one estimate, the penetration rate was 10.4% in 2023 and is expected to reach 20.8% in 2030.Â
Compared with traditional exteriors, smart exteriors boast higher content-per-car value.
The cost of traditional exteriors is about RMB2,000 per car (excluding headlights), largely for bumpers, exterior rearview mirrors, sealing strips, and wheel trims. If the cost of headlights is added (by RMB2,800-3,800 for LED headlights per car), the cost of exteriors per car will be around RMB5,000.
In the intelligent upgrade process, the value of exteriors has surged. For example, the digital grille is more than 10 times the ordinary grille, the laser headlight is more than 3 times the LED headlight, and the hidden electric door handle is 6.7 times the ordinary door handle. Overall, the content value of smart exteriors per car will be more than 5 times traditional exteriors, that is, the cost per car is RMB10,000 (excluding headlights), and plus headlights, the content-per-car value is higher than RMB20,000.
New energy passenger cars pioneer smart exteriors. On ResearchInChina’s estimate, China’s new energy passenger car exteriors market will be worth RMB67.55 billion in 2024, of which smart exteriors will be valued at RMB25.05 billion, accounting for 37.1%. It is predicted that China’s new energy passenger car exteriors market will be valued at RMB153.19 billion in 2030, of which smart exteriors will take an over 50% share.
2. In the trend towards intelligence, some traditional exteriors are being replaced by intelligence.
As exteriors tend to be smart, some traditional components will gradually be replaced by intelligence, and even non-exterior designs will appear.
1) Non-B pillar design
The non-B pillar design is usually a non-B pillar + hinged door design. Not only is the door opening full of sense of ritual, but the extra-wide door opening (maximum opening of more than 1m) makes it more convenient for users to get on and off the car. The non-B pillar design has received much attention in the market, especially from household and business users who appreciate the convenience and space utilization of this design.
Zeekr MIX, to be launched in the second half of 2024, adopts a non-B pillar design. The removal of B-pillar can further expand the opening area of ??Zeekr MIX’s doors, enhance the airy and open feel and flexibility of the car’s interior space, and make the car’s interior layout more flexible.
2) Non-door handle design
Hidden door handles are quite controversial, and non-door handle solutions then come out.
In the keyless entry trend, non-door handle design becomes possible. Non-door handle design is a new solution developed for users to unlock and get in and off cars. It often applies wireless inductive unlocking technology and power door system. When the user carries the smart key or authorizes the car via the mobile phone APP to unlock, the control unit triggers the operation of the built-in electric actuator of the door after receiving the command, so that the door automatically pops out or slides at a preset angle, so as to facilitate the user’s entry.
In April 2024, Jiyue 07 was unveiled at the Auto China. It adopts a non-door handle design. In addition, Jiyue 07 is also equipped with intelligent inductive power doors, allowing the user to open the door with one button and enabling more intelligent door opening.
3) Non-grille design
The original intention of grille design was to meet the engine’s need for air intake and heat dissipation. As new energy vehicles develop, this demand has become much weaker. Non-grille design will become a trend in the future.
At the Tokyo Motor Show in November 2023, Nissan’s first all-electric crossover concept car Hyper Urban removed its typical V-Motion grille. This means that in the wave of electrification transformation, Nissan begins to use a non-grille design.
4) Hidden antenna design
Automotive antennas tend to be miniaturized and integrated, and hidden design is one of its future development directions.
The significance of hidden antennas is that the introduction of antennas does not affect the appearance of the vehicle body, that is, they are hidden somewhere on the body. Hidden design requires overall consideration of what types of antennas are used and how to simplify antenna deployment on the vehicle body.
5) Non-rearview mirror design
In current stage, the camera of the electronic exterior rearview mirror is installed in the positions similar to ADAS, mainly on the traditional exterior rearview mirror or at the rear of the vehicle. There is also overlap between the functions of the two, such as blind spot detection and lane change assist based on side cameras. At present, one direction of OEMs to achieve overall cost reduction is reuse of ADAS cameras. From the perspective of field of view, the two have the possibility of reuse. In this period, the camera of the electronic exterior rearview mirror still lies in the traditional positions.
In the future, as traditional rearview mirrors disappear, electronic exterior rearview mirrors will only exist for the purpose of installing cameras, and become much less necessary. Some OEM once mentioned its vision of the future electronic rearview mirror solution in which the camera is expected to be moved to the side of the front hood (position â‘¡ in the figure below) or the top corner of the window (position â‘¢ in the figure below). By then, the “non-rearview mirror” design will be realized.
