According to the data of China Automobile Association, in the past March, domestic passenger car sales were 1.864 million units, down 0.6% year-on-year, the performance is not outstanding, but it is worth noting that the new energy vehicle market continued to rise against the trend in March, with cumulative sales of 484,000 units in the month, an increase of 114.1% year-on-year, of which the sales of new energy passenger cars reached 4.61 million units, an increase of 117.0% year-on-year.
High-end intelligent pure electric rookie Zhiji L7 debuted
Since the beginning of the decline in domestic automobile sales in 2018, the overall performance of passenger cars has been unsatisfactory, but the performance of the new energy subdivision sector has not decreased, in the past March, affected by the rise in raw material supply prices, many new energy vehicle manufacturers have raised the price of their models, but the sales of new energy vehicles have increased, which is enough to show the potential and advantages of new energy vehicles.
Among the new energy vehicles, Weilai, Xiaopeng, Ideal, Nezha, Weima, etc. may be the new power brands that most people are familiar with, but for those who really pay attention to the automotive industry, they should also know Zhiji Automobile. Zhiji Automobile is an automobile brand jointly built by SAIC Motor, Zhangjiang Hi-Tech and Alibaba Group, and in January 2021, it officially released the high-end intelligent pure electric vehicle brand - IM Zhiji.
On April 17, Zhiji Automobile officially announced that its first model, Zhiji L7, was officially listed, and the price was 368,880-408,800 yuan after subsidies by manufacturers, and a total of 2 models were launched. Previously, during the Shanghai Auto Show in April 2021, the Zhiji L7 has been pre-sold, with a pre-price of 408,800 yuan, so the official listing is actually a new entry-level model - Zhiji L7 Dynamic.
Driving control is the central idea that I want to expound
The theme of the launch of the Zhiji L7 is to challenge the Guinness World Record of "Longest Electric Drift", and its conference revolves around "performance" and "driving control".
First, the Zhiji L7 broke the Guinness World Record for a continuous drift of 42.17 km at the Porsche Experience Center in Hockenheim, Germany, in August 2020 with a continuous drift of 1 hour and 6 minutes, 258 laps and 43.646 km, becoming the holder of the new record.
From past experience, the listing of most high-end intelligent new energy products is indispensable to the modification of intelligent performance, but Zhiji L7 is not so, but focuses on performance and control.
In fact, the reason why the L7 dares to challenge is simple, that is, the strength allows. First of all, it adopts a new performance pure electric architecture, that is to say, it has an excellent foundation. In addition, with the blessing of the 400V voltage platform, zhiji L7 is also equipped with a direct waterfall oil-cooled motor with a very high power density, with a maximum power of 425kW, and the maximum torque has also gone to 725N·m. Zhizi Automobile co-CEO Liu Tao is very confident to the traditional luxury car brand in the large and medium-sized car representative - BMW 5 Series power performance and Zhiji L7 power performance, from the data level, Zhiji L7 power output is more than 2 times higher than the BMW 5 Series 2.0T high-power engine power output, the official data shows that its 100 km acceleration only takes 3.87 seconds.
Power is, of course, only an important element of performance and handling, but not all. In addition to power, true performance is just as inextricably linked to the chassis, steering, braking, and more.
Zhiji L7 not only has a shaft-to-load ratio of 50:50, but also has an all-aluminum chassis structure, but more importantly, there is a unique four-wheel steering full-drive system of the same level, which adopts electrified four-wheel vector drive technology, and the rear wheel can achieve a large steering angle of 12 ° in both directions. At low speed, the front wheel and the rear wheel are deflected in reverse, and the rear wheel is actively outward to effectively reduce the turning diameter; when the high-speed corner, the rear wheel and the front wheel are deflected in the same direction, thereby effectively controlling the tail of the vehicle and improving the body following. Thanks to this outstanding technology, Zhiji Automobile proposed the concept of "virtual wheelbase".
If that's not enough, there's also an electronically controlled intelligent damping suspension that adjusts the full-lane condition instantaneously in 10 milliseconds. The suspension provides a 5x damping soft and hard adjustment for a ride that balances comfort and sport. Liu Tao, co-CEO of Zhiji Automobile, said that some people may wonder why the Zhiji L7 is not equipped with air suspension, because they believe that air suspension is actually mainly to get closer to comfort, and they want to be more biased towards performance and control performance, so they finally chose CDC electronic control suspension.
Of course, a good chassis is not just a matter of material stacking, but more critical and central to tuning. The Tuning of the Zhiji L7 comes from the world's top team in automotive performance tuning - the Williams Forward Engineering Team, and the real master team from F1 racing. Official data show that the work lasted a year, before and after two rounds, a total of 108 chassis indicators and software parameters of the careful testing and adjustment, which can be said to be a very important reason for the zhiji L7 to be able to ride the track.
Design is also about performance
In fact, the Zhiji L7 also takes into account the performance in terms of shape design!
"Pure - Zhiji" is the design concept of Zhiji Car L7, in the case of no need for large-area grille heat dissipation, the closed front face design has become the mainstream design of pure electric new energy models, this design not only brings a new visual experience, but also better improves the aerodynamics. The Zhiji L7 has obtained an ultra-low drag coefficient certification of 0.21Cd at the China Auto Research Wind Tunnel Center in Chongqing, which is the top three levels of global mass production vehicles.
As we all know, the wind resistance coefficient has a very important role in vehicle performance, especially for automotive products that pursue extreme performance, and the influence of the wind resistance coefficient on the energy consumption of vehicles is also very important. There are data show that for fuel vehicles, when the speed exceeds 80km/h, 60% of the energy output is to overcome wind resistance, when the speed exceeds 120km/h, 85% of the energy output is used to overcome wind resistance, similarly, for pure electric new energy vehicles, the reason should be the same, then the lower wind resistance coefficient can undoubtedly effectively reduce energy consumption and increase endurance, which should also be a factor of zhiji L7 CLTC cruising range of up to 615km.
In addition to the wind resistance coefficient, Zhiji Automobile also has a concept and data worth mentioning, that is, the anti-rollover coefficient. According to the formula of the U.S. Highway Traffic Safety Bureau, the anti-rollover coefficient = t/2h, where t represents the wheel base, h represents the center of gravity, and the wheelbase of the Zhiji L7 reaches 1664mm, while the center of gravity is as low as 490mm. Elementary school mathematics tells us that the greater the divisor, the smaller the divisor, the greater the quotient, according to the publicity can obtain the anti-rollover coefficient of Zhiji L7 is 1.69, and the data given by the US Highway Traffic Safety Bureau is the anti-rollover coefficient between 1.25-1.45 for the four-star performance, 1.45-1.6 for the five-star performance, it is obvious that the anti-rollover coefficient of the Zhiji L7 has reached the standard of super five stars. This actually brings an effective guarantee for its driving safety in the corners, and the natural driving limit will be higher.
In fact, the achievement of zhiji L7 is achieved because its power battery adopts a "horizontal layout", which effectively reduces the overall height of the battery, which can make the center of gravity of the vehicle lower, of course, obviously, also thanks to the excellent performance of the vehicle width.
Of course, Zhiji Car does not focus on intelligent does not mean that Zhiji L7 is not intelligent, for example, it sets up a supercar mode, which can bring an immersive driving experience, in this mode, the 39-inch giant screen can automatically sink, bringing better driving vision to the driver, at the same time, the audio can also simulate the V10 super running sound wave, bringing more adrenaline soaring driving experience.
Automotive Network Review: To subvert traditional norms and redefine new standards
The highlights of the Zhiji L7 can be said to be numerous, such as the Icon-M DLP digital projection headlights that can communicate emotions, ISC intelligent interactive taillights, NVIDIA Xavier chips, 12 ultrasonic radars, 5 millimeter wave radars and other intelligent advantages; in addition, zhiji L7 is also equipped with Brembo brake calipers and specially customized Pirelli high-performance sports tires.
What Zhiji Auto wants to emphasize is that the rapidly changing electrification technology will completely subvert the rules of the traditional luxury car game and redefine the performance standards of the car. So, has the product strength of Zhiji L7 impressed you?
