If it looks good, it should also be used.
After taking a few introductory classes at art center colleges and universities such as Chris Bangle, former design director of BMW, Franz von Holzhausen, the current design director of Tesla, etc., I found that I could not keep up at all, although I did not have a relevant diploma, but I thought that I was still very picky about car design.
Beautiful?
To be honest, before the Zhiji L7, almost no domestic four-door sedan could impress me at this angle. The sleek waist and parabolic roof exude a modern elegance. Continuing to gaze at the rear, the ducktail-shaped through taillights wrap around the rear side, enhancing the sensory impression of the width. The gaze returns to the raised eyebrows, and the elegant lines cannot hide the beauty of moving power.
From the bottom of the A-pillar to the waist line at the rear of the car, I want to give it a name called "Demon Line", it's too messy. It is not a simple single curvature curve, but a flexible movement with the relationship between the profiles, without losing effort to outline a full tail contour.
I would like to ask about the endorsement fee
I'm sorry I drifted, to say that the line of L7 is not Kardashian, nor Is it Liu Wen, it is Gu Ailing.
By the way, even the car logo is a solid aluminum alloy processed by CNC. At the moment when chrome plastic parts are rampant, it is indeed a clear stream, and the cost is not low.
Beauty and strength coexist
But is that enough? In this era of inner volume, the value of appearance is only part of the comprehensive strength. The production version of the L7 is currently an Xavier chip-driven visually assisted driving solution. However, Zhiji's gameplay is more clever, has reserved the interface, and will upgrade to two Robosense M1 lidar + NVIDIA Orin X chips for free when appropriate, and enter the first echelon of the automatic driving hardware war.
In terms of assisted driving, Zhiji also showed actual measurements of urban and elevated road conditions in Shanghai, Suzhou, Chengdu and Guangzhou last year. The lifetime free IM AD intelligent driving system directly eliminates tens of thousands of outright fees or subscription fees of hundreds of months. There is nothing wrong with making money, but at this stage of charging, it is indeed a bit of a taste of cutting leeks. At a time when autonomous driving is not yet widespread and the ability is still in the dawn, the practice of free for life is not only a favor to users, but also responsible for promoting the industry.
When it comes to performance, traditional mechanical properties are still important. The 425 kW and 725 N·m dual-motor 4WD all-electric sedan, in addition to a 3.87-second zero-hundred-hundred-second acceleration time and a 32.69-meter 100-kilometer braking distance, has a 1,650/1,660 mm ultra-wide front and rear track that exceeds the BMW M5's, driving expectations are very high. Dual motors, double wishbones, variable damping suspension, Brembo and other factors in the domestic high-end electric vehicles have been seen strange, the key is how to cook these good dishes into a delicacy in a short period of time.
Two British chefs
In order to open up the gap in the control, Zhiji spent tens of millions to hire Williams Forward Engineering (WAE). Is the relationship between WAE and Williams F1 as inextricable as the relationship between Porsche Engineering and Porsche? In order to determine this, I also participated in the test drive event held by Zhiji Automobile at the Shanghai Tianma Mountain Circuit.

The trams are fast, but it's more important to drive well.
The safety car is said to herald a subsequent track kit.
Manipulate the right taste
After two laps, the corners of my mouth went up. I have to say that the track of the L7 feels beyond expectations. The problem of the model 3 Performance, which is recognized as a pure electric track weapon, is too sensitive to steering inputs in the corners, and it is completely absent on the exceptionally stable Zhiji L7.
Look at this gesture
The 50:50 weight distribution and 490 mm center of gravity at the front and rear offset the bulkiness of a vehicle weighing more than 2 tons, although many electric vehicles do. Amazingly, the roll in Sport mode is very well controlled, further reducing the car's sense of weight. Hopefully, the official will announce a series of track lap records to show the strength of the L7.
It seems that the four thousand CDC shock absorbers and tens of millions of CDC shock absorbers that were discarded during Williams's "further training" are not lost, but the L7 is full of money in control. It seems that these British guys did not lie to us Chinese ah, is quite professional.
Amazingly, after the L7 cut into comfort mode, you can feel the chassis become significantly softer, and the feeling of passing the speed bump is instantly much more decent. But there is no nasty pitching back and forth and residual dynamics that cannot be contracted, that is, there is no so-called sense of sailing.
The black column is the CDC
In addition to the excellent chassis, the tire selection is the most grassy part of this car. This set of front and rear tires almost does not ring on the track, that is, silently grasping the ground, grasping the ground, grasping the ground, never ending. Before I could fully exit the corner, I deliberately added the throttle input to the test. Even so, the rear wheels move slightly sideways, and the tires make a little friction sound and then converge on their own.
In fact, with the support of Williams, zhiji L7 has optimized the triangle rubber form of the tire, the height of the cord anti-wrapping, the angle of the steel belt, the formula of the tread glue, and the rolling resistance coefficient of the tread. At a time when electric vehicles are using low-roll-resistance tires to squeeze out a thread of endurance to make the book data look better, the Pirelli P0 of the first 245/40 R20 and the rear 275/35 R20 on this L7 has broken the norm and has a very rare choice to take the route of high grip.
Isn't the high limit, fast response, low-pitch, and neutral control characteristics the so-called control that most impresses the senses? L7 in the chassis this piece, it can be said to be a direct poke in the heart, basically anyone can have resonance. After driving two laps, A bunch of oil trucks within 1 million suddenly appeared in my mind. Aside from the increasingly expensive V8, I don't seem to miss anything.
Stacking in place
The log pulled out of the P-Box
On the test field within the track, the L7 carrying a driver and a passenger, the 100 km acceleration measured time was 4 seconds, and in the Zhiji staff @Jason Xiaohei single test, it even made a better than the official score of 3.8-3.85 seconds (because the resolution is 0.05 seconds). The 250 kW flat wire winding motor on the rear axle is also a black plate of magnesium alloy housing specially created for this car. Magnesium alloy, as a stronger and lighter metal material than aluminum alloy, is also a high-grade material used in F1 wheels.
Many people say that electric vehicles can't last, so they are not suitable for running tracks. In fact, with the construction of the energy replenishment network, this problem will be alleviated. The real pain point of electric vehicles not being suitable for the track is the same as that of fuel vehicles, which is thermal attenuation. The heat dissipation requirements of the motor when it continues to operate at peak power are actually very high.
Schematic diagram of direct waterfall oil-cooled motor cooling
In the past, the water-cooled motor could only have a power "stud" time of 10 seconds, and the L7 of Zhiji could "shuttle" for 30 seconds. This is because it uses a more efficient straight waterfall oil-cooled heat dissipation technology, which ensures stability and durability at high power outputs. In fact, throughout the event, the 0-100-0 km/h project experience vehicle can last for a whole morning, and the intermission is also because of charging.
32.69 meters, which is the braking distance of Zhiji L7, and it is also the peak of the actual measurement of domestic cars. The configuration behind this data is also very top. The front wheels are four-piston calipers developed by Brembo for Tomo and with an exclusive exterior design with 365 mm FNC brake discs. Many manufacturers will use the combination of Brembo calipers + domestic discs to reduce costs, but the brake discs of L7 are also from Brembo.
Orange calipers, handsome
The rear wheels are also equipped with a huge 356 mm ventilated disc and are paired with large single-piston frame floating calipers from mainland China (similar to the one on the Model 3 P) and incorporate electronic parking. This kind of caliper is not only stronger than the ordinary floating caliper, the key is that the appearance value is also very online, and even if you don't look carefully, you can't see that it is a floating caliper.
The most earthy disc brakes are like this.
It cost 400,000 to buy a car, if the brakes are like this, can you stand it?
It's actually the same as Alfa Romeo Giulia
In the upstream part of the braking system, the Zhiji L7 chose the Continental MK C1. Fully decoupled brake master pump for this 1-BOX solution. In terms of brake system pressure speed, the conventional hydraulic system is completed by a gap of three times the 150 ms vs 450 ms. The 300 milliseconds faster will be directly reflected in the reduction of the emergency braking distance in real life.
The swans that swim freely on the surface of the water are actually frantically flapping their fins under the water. Since the pursuit of elegance, there is no need to influence the perception behind it. Another great benefit of this braking system is that when the ABS is started, it will not be hit by the action feedback of the ESP pump. In this way, the driver will not be frightened by the sudden vibration and release the brake when braking at full force.
Snakeskin walks in place
Flexible big chunks
The strengths of air suspension are the increasing stability and stiffness characteristics at high loads and the lifting function. The advantages of handling and comfort that are reflected in the car are not great, and this part of the help is the CDC.
Although the sinking trend of air suspension configuration in the domestic new forces has been rolled into the 300,000 class models. But the 408,800 L7 Angel Wheel edition insists on not carrying air suspension. The sunken configuration instead is the standard rear steering, which is also the first to appear at this price point.
Comparable to the turning diameter of the A class
The Wheelbase of the Zhiji L7 is 3,100 mm, but it can make you feel that its wheelbase is only 2,580 mm, or it can make you feel that it has 3,250 mm. And its minimum turning diameter is only 10.8 meters, which makes A-class owners doubt life.
Configuration of the D-Class
Thanks to the All-Out Ball Head Multi-Link Rear Suspension, the Zhiji L7 can support a greater steering angle of 12 degrees in both directions. (The specific principle can be seen in my previous article: "This chassis of zhiji, friends may need to benchmark it.") At speeds below 40 km/h, the rear wheel steering system allows the rear wheels to fight back and increase flexibility; above this speed, it is in the same direction for increased stability.

Luxury is an attitude.
Cross-level configuration
And the horn
Users in the era of stacking materials and rolling have a more delicate understanding of the grade of leather. At a time when some new power brands are still charging for nappa leather, Zhiji Auto is laughing. Because the L7 is not stingy in this regard, it directly put on a set of German Bavarian semi-aniline leather interior. Hemianiline is present one notch higher than Nappa skin and is standard on Maybach S-class and S-class, respectively.
The reason I didn't feel the obvious smell of the new car when I got on the bus was the exclusive pure taste workshop of Zhiji Automobile. This game is actually a bit of a refresh in the industry's control of the quality of air quality in the car. Zhiji claims that after a series of exclusive customization processes such as extraction - reduction and removal of aldehydes , vacuum devocation - odor removal - 100% full contact lasting fresh air ventilation, etc., the cockpit aldehyde data of zhiji L7 at the factory is about equal to the level of similar products after 180 days of use.
This perspective is also good to look at
In terms of glass, Zhiji also continued to pay attention to blood. Many models at the same price point or even higher usually use double glazing in the front or rear side windows according to positioning, and the Zhiji L7 simply makes all the glass on the car double-layered, including the small triangular window on the rear door. The sunroof is also coated with the most insulating silver plating.
The logo on the steering wheel is actually aluminum alloy
At the cockpit hardware level, the Zhiji L7 let go of the imagination and created an unprecedented two lifting and lowering screens totaling 39 inches on the dashboard, and the ultra-narrow bezel of the 12.8-inch AMOLED 2K central control screen is also a significant factor highlighting luxury. I can already imagine me fiddling with the screen being sold rolling my eyes, it must be fun.
Did you find the PUP rendered by isc?
The Cockpit Configuration of the Zhiji L7 in terms of size, performance, intelligent driving configuration and audio power has undoubtedly formed a clear competitive relationship with the NIO ET7. However, compared with the more commercial attributes of et7, the slightly lower price of the Zhiji L7 is more prominent in sports positioning, while there are novel configurations such as DLP projection headlights and ISC intelligent interaction systems, forming its own unique selling points.
Do you still need nostalgia?
I only nostalgic for the V8, but it was too expensive.
To reiterate, the car's center of gravity is only 490 mm high, which is directly 5-6 cm lower than similar size fuel vehicles. Traditional fuel vehicles have painstakingly engaged in various spending tricks such as horizontal confrontation and dry oil pan, and the electric vehicle era has come, and the judgment has been directly declared obsolete. It seems that feelings are placed in front of absolute performance, and sometimes they are vulnerable.
Moreover, the blow to the fuel vehicle in terms of power response of the tram is crushing. Electric vehicles have a torque response gap of 60 ms vs 1,200 ms compared to fuel vehicles, and they can exert maximum torque from a stationary start.
However, I still often see questions like this on the Internet:
Therefore, zhiji such a large car with a wheelbase of 3,100 mm, luxury configuration is so much, why do you need to control?
In fact, a big and fast electric car, no control is the most terrible. Zhiji L7 can do so much investment in driving control, even at the expense of sending a car to study in the UK, is not it for this big and fast car, can provide a safer and happier driving experience?
Perhaps, Zhiji just wants to tell a point through the product power of L7: electric luxury cars, fish and bear paws can have both.
