Zhiji Automobile, if I just say the name, this strange brand will definitely make many people think that this is another PPT car-making force that will not live for a few days, but if I say SAIC Zhiji, everyone’s views on it may be completely different. For the automobile industry, which is a heavy asset industry, "fighting for dad" is sometimes really important. As the highest-level high-end pure electric vehicle project in SAIC, Zhiji Automobile made such a bold Slogan as "What a smart auto time should look like" as soon as it appeared. So how will this rich second generation born with a golden key behave? Today, let’s take a closer look at its first medium and large car, Zhiji L7.
1. The mainstream luxury and sense of technology
The product positioning of Zhiji L7 is a pure electric medium-sized and large-sized car. The appearance design of the new car looks very avant-garde, and the simple curved surface and tough lines highlight a strong sense of advanced. The recognition of the whole front face is very high.
The unique lamp group shape of the front face makes it look like a product from several years later. It is also equipped with a set of intelligent DLP daytime running lights and a 2.6 megapixel projector intelligent lighting system, which can project navigation, car conditions and other information to the road. But as far as my personal aesthetics is concerned, I always feel that the daytime running lights in the second half are somewhat redundant. You may also wish to imagine what it looks like after removing the lower part of the daytime running lights. Will it look better?
There is a small bulge in the center of the car roof of Zhiji L7, which is not a laser radar, but three high-definition cameras, which are used in the car intelligent camera system Carlog. Three cameras with a single pixel of up to 48 million work at the same time, automatically splicing to achieve 180 ultra-wide angle distortion-free shooting. Support 4K, which can realize super night scene, high dynamic range, delay, slow motion and other photography modes. At the same time, this set of Carlog also supports one-click editing and one-click sharing to social platforms, which can be connected to major live broadcast platforms for live broadcast from the first perspective.
The side of the car body is the most beautiful angle of Zhiji L7. The slender body is further strengthened by the heavily inclined A-pillar, and the drag coefficient is only 0.21. The straight waistline extends to the rear of the car. At the same time, the exaggerated rim, with all bright black trims, makes the whole car look younger and sporty. In terms of dimensions, the length, width and height of Zhiji L7 are 5098*1960*1482mm and the wheelbase is 3100mm. The length is exactly the same as that of Weilai ET7, and the wheelbase is 40mm more.
In addition, there are many hidden door handles, frameless doors, B-pillars and cameras on leaf boards for assisting driving systems, which reflect the product level. Judging from the camera layout of the whole vehicle, Zhiji L7 has an industry-leading visual perception solution.
At the rear of the car, the area of the rear windshield is very large, and the shape of the sliding back further increases the sense of movement of the whole car, while the design of integrating the transverse taillights and the tail wing is scientific enough. The shape of the bottom lower bumper also highlights the sporty atmosphere, integrating the diffuser and the deflector, highlighting the high-performance positioning.
The taillights are similar to the ISC pixel interactive taillights on HIHi X. There are 5000 LED light sources in ISC taillight group, and a display screen with intelligent interactive function is formed outside the main taillight light source, which can echo the front of the car. For example, when pedestrians pass in front, the rear display can tell the rear car "There are pedestrians in front, please slow down and wait"; In case of signal light, the remaining seconds can be displayed at the rear of the car; After driving into a crowded lane, you can also thank you through the taillights.
Another highlight of Zhiji L7′ s exterior design is the choice of car paint with quite different texture and color. At present, there are three colors: Di Anna white, which uses top German patented technology and nano-scale raw materials to make extremely fine muscovite appear soft silk texture; Comparable to sketch graphite, Lie Bin black with great hierarchy and fluidity; And Raphael tea, which shows a light and elegant color and enamel feeling from a distance, and a slight golden feeling of sand grains from a close look.
2. The integration of minimalism and technology
In the interior, the biggest feeling of Zhiji L7 is the minimalist sense of science and technology. In the central control area, the upper and lower large screens are the core elements, and the hidden air conditioning air outlet, completely canceled physical buttons, specially shaped steering wheel, and pure white color matching make the interior of the vehicle look very futuristic.
The world’s first 39-inch giant smart scene screen looks very shocking, with a screen-connecting resolution of 4320X720(4K) and 1920X720(2K). Incell technology makes the look and feel more transparent, and the whole screen-connecting can realize intelligent lifting and cross-screen interaction. However, the current display vehicle is not the final version, and the main functions and interfaces have not been officially opened. Can’t do specific experience.
3. Silicon-doped lithium supplement technology has a battery life of 1000 kilometers.
In terms of power, Zhiji L7 provides two driving forms: rear drive and four-wheel drive, among which the four-wheel drive version can achieve a maximum output of 400kW (peak torque is 700N·m), and the acceleration time of 100 kilometers is only 3.9 seconds; In terms of battery life, Zhiji L7 comes standard with 93kWh battery, which can reach the cruising range of 615km under NEDC. In addition, the government has also introduced a high-end version of 118kWh battery, which adopts silicon-doped lithium supplement technology, which can not only achieve the energy density of 300Wh/kg, but also improve the battery life of NEDC to 1000km.
At the same time, the lightweight all-aluminum chassis, the precise front double wishbone/rear multi-link independent suspension and the rear wheel steering system of the same model as the new Mercedes-Benz S-Class can realize 12-degree steering in both directions; CDC intelligent electronic control damping system, the response time is only 10 milliseconds; The chassis carefully adjusted by WAE Williams Foresight Engineering Company, the world’s top engineering team in the same door as F1 famous Williams team, will provide an excellent driving experience.
In terms of charging, Zhiji L7 is also equipped with 11KW high-power wireless charging function, which can charge 10.5 kWh in one hour, and can achieve 70-80km NEDC battery life.
4. Mobile supercomputers
Finally, let’s talk about intelligent driving. Zhiji L7 provides two schemes. One is the standard visual perception scheme based on high-definition cameras. The hardware includes 12 cameras, 5 millimeter-wave radars, 12 ultrasonic radars, etc. With NVIDIA Xavier chip, high-precision IMU and high-precision map, the whole scene and over-the-horizon road condition perception can be realized. The other set will adopt the lidar sensing scheme. Two laser radars with the wavelength of 1550nm will be placed at the top of the A-pillar on both sides, and the chip will adopt the current top-level NVIDIA Orin X (the same model as Weilai ET7) with a computing power of 500-1000 TOPS.
It is worth mentioning that the Zhiji L7 is different from the traditional vehicles with more than 90% distributed ECU controllers at present. It adopts a new generation of domain-integrated central computing digital architecture and integrates four domain controllers-IPD intelligent driving center, ICC intelligent computing center, ICM intelligent cockpit center and IMATE intelligent partner. With the help of TTTech multi-chip real-time data interaction and 1Gbps Ethernet light speed communication, Zhiji L7 has become a mobile supercomputer with strong computing power.
Summary:
Zhiji L7 will officially open the reservation at Shanghai Auto Show, and the delivery may have to wait until the first half of 2022. Its delivery time just collided with Weilai ET7. From the aspects of vehicle positioning, style, dynamic performance and automatic driving ability, Zhiji L7 can be said to be a comprehensive benchmark for Weilai ET7, and even its name is very similar. Regarding pricing, I guess Zhiji L7 will definitely aim at ET7. Then, with the brand influence of SAIC, can Zhiji L7 become the rival of Weilai ET7?
