The 2024 Zhijie S7 has a total of 5 models, with a price range of 249,800-349,800 yuan. S7 is a product of Huawei's smart car, which belongs to the model jointly built by Chery and Huawei, and has Huawei's Turing intelligent chassis, Huawei Hongmeng cockpit, Huawei motor, Huawei lidar, etc., so what is the strength of Chery and Huawei's car products? Let's analyze it in detail.
Chassis suspension
Zhijie S7 adopts Huawei's Tuling intelligent chassis, with four main technologies, including Huawei ADS road surface perception, intelligent vehicle state perception (iVSE), Huawei DATS dynamic adaptive torque control, Huawei xMotion intelligent body collaborative control, the number of co-control devices is 3 times higher than that of the traditional chassis, and the chassis suspension of a car needs to face many problems when driving, including from front and rear, left and right, Up and down, the force in six directions, if the sensing parts increase, the vehicle can be adjusted in a timely manner through variable damping.
The S7 four-wheel drive version comes with CDC variable damping shock absorbers and air suspension, which can be adjusted 100 times per second, and the air suspension means that the body height can also be divided into 4 gears, and the overall tuning is adjusted by Huawei's German research institute, the vehicle's turning radius is 5.67m, and in the elk test, it passes at a speed of 83.1km/h, and the lateral acceleration reaches 1G, and the high-speed cornering ability is worth affirming.
Mechanical part, S7 is equipped with a virtual kingpin double wishbone front suspension, the original integrated wishbrille, split into two connecting rods, changed the axis of the kingpin, the intersection of the two connecting rods extension line determines the kingpin axis, which means that without changing the chassis structure, the kingpin axis is moved outward, named virtual kingpin, this design makes the vehicle more stable, even in sharp corners, it can also bring a more stable steering feeling.
The rear axle is a standard five-link suspension, compared with the H-arm multi-link structure with more at the same price, the support capacity of the suspension is a short board, but for the car, the five-link suspension is more flexible, and the engineer can adjust the price more freely. In particular, in the face of speed bump extrusion or high-speed lateral extrusion, it can be finely tuned, which is more comprehensive than H-arm multi-link or E-shaped multi-link, which has been verified in many Audi models.
The downside of this suspension is how to tune the complex virtual kingpin double wishbone and five-link linkage, which is a difficult problem and can even backfire for less experienced car manufacturers, and more bushings means higher maintenance costs after longer kilometers.
The practicality of the 2024 Zhijie S7
First drive
Zhijie S7 is equipped with Huawei's DriveONE 800V silicon carbide motor, the four-wheel drive version adopts a front AC asynchronous motor + rear permanent magnet synchronous motor four-wheel drive combination, with a comprehensive power of 496 horsepower, 3.3 seconds can break 100, the speed of the motor reaches 22000rpm, and the rear section of high-speed driving is not false, and the speed of the rear-wheel drive and four-wheel drive versions can reach 210km/h. The power of the single-motor version is 292 horsepower, and it can break 100 in 5.4 seconds, and the entry-level rear-wheel drive version has reached the standard of a sports sedan, which is faster than the acceleration of a number of small steel guns.
In terms of braking, the IPB intelligent integrated braking system is adopted, which has a faster braking response, and the braking distance is 33.5 meters from 100 to 0 km/h. S7 uses an 800V high-voltage fast charging platform, equipped with a lithium battery from Jiangsu Times, there is only one supplier, the capacity is 82 degrees or 100 degrees, depending on the model, the CLTC range is between 630-855km, and the fast charging time from 30% to 80% is 15 minutes, and there is no range anxiety when driving in urban areas.
Second ride
The length, width and height of the S7 are 4971mm, 1963mm and 1474mm respectively, and the wheelbase is 2950mm. It is not eye-catching among the 300,000 or so cars, and some models are more than 5 meters long. The S7 also has some interesting features in the interior, such as the olive sports steering wheel, which has a smaller diameter and a flat design to immerse the driver.
The co-pilot has a flat multi-function instrument panel, and is also equipped with a zero-gravity seat with one-button suspension, of course, it should not be turned on when driving, which will affect the protection ability of the seat belt, it is recommended to turn on when parking and resting, S7The seat backrest of the rear row can also be adjusted, the heating and ventilation function needs to be optional, and the short board is that there is no rear seat massage function in the whole system, and more attention should be paid to the rear riding experience for medium and large cars.
Third Cockpit Entertainment/Intelligent Driving
S7Standard configuration12.3Inch LCD instrument cluster and 15.6Inch central control screen,Built-in HongmengOS4Car machine system,Car machine response is smooth,But there is no co-driver entertainment screen,Huawei MagLink design means that the rear row can expand the screen by itself,Automatically connect after hanging the screen。 Intelligent driving is the advantage of the 2024 model, equipped with Huawei's visual intelligent driving ADS basic version, the pure vision solution achieves L2 driving assistance, and the autonomous driving is only available on high-speed sections.
Except for the entry-level version, all other models come with a 192-line Huawei LiDAR, which can detect up to 250m, and the forward AEB automatic emergency braking support speed is increased to 150km/h, which can brake at 120km/h and actively identify pedestrians, vehicles and other targets.
Car selection detective point of view: 2024 S7 uses Huawei's pure visual intelligent driving for the first time, and the medium and high-end models are also equipped with 192 lines of Huawei lidar, which is not inferior to other new car-making forces in terms of intelligent driving, and is worthy of affirmation in terms of suspension structure, power, battery life and charging speed, etc., its shortcomings are that the riding space is general, the seat configuration does not meet the positioning of medium and large sedans, and the air suspension only appears on four-wheel drive models, and the price is high, more than 320,000 yuan, what do you think of the cooperation between Huawei and Chery? Welcome to discuss.
