At NIO Day 2021, the one-year-old NIO ET7 officially announced that it will be officially delivered on March 28. While everyone is looking at the ET7, zhiji's first model, the L7 Beta Experience, is also officially delivered on December 26, 2021.
Regarding the positioning of domestic electric vehicle brands, the two high-end pure electric cars have also ushered in the moment of "head-to-head confrontation", which is bound to have many points of view.
And today we will take a closer look at whether it can represent Chinese brands to explore the high-end market.
First, the model introduction
Both models are positioned as high-end medium and large cars, and the price is also more than 400,000 yuan.
On January 1, 2022, ET7 updated the 2022 subsidized price to include:
75 degree battery pack national supplement 11,340 yuan, the starting price after subsidy 436,660 yuan;
The 100-degree battery pack is supplemented by 12,600 yuan, and the starting price after subsidy is 493,400 yuan.
The Zhiji L7 has previously announced its retail price, the current angel wheel version is scheduled to be sold out, the current A round version, the price is still 408,800 yuan.
In terms of delivery time, the two are also "comparable". On the 2021 NIO Day, NIO Officially announced the delivery time of THEO ET7, which will start locking orders on January 20, 2022, and the ET7 will officially start delivery on March 28, 2022.
At present, users of the A-round seat of Zhiji L7 can enjoy 5 major benefits: "A-round user crystal benefits", "IM AD intelligent driving full-featured package for 3 years free use and upgrade", "data rights exchange software and hardware upgrades", "7 days car purchase hesitation period", "IM Care 7*24 hour worry-free service".
According to the plan, the first batch of 200 Beta trial versions of L7 have been delivered at SAIC Lingang Intelligent Factory, and by the end of February this year, the Zhiji L7 test drive will be successively in the store, and the real car test drive will be fully opened in early March, and the new car is also planned to start delivery in April.
Second, the design comparison: performance coupe VS executive car
In the era of electrification with a hundred flowers, we have also seen many new designs where sensibility and rationality collide, how to restore the style of concept car design, create a new wave of design, let users also enjoy cross-era interactive experience, and also become the design "inspiration" of current car designers and cash in imagination.
For example, the L7 exterior design adopts a more powerful swooping front and streamlined body design, matching the 5098mm body length, 490mm low center of gravity and the wide shoulder line design above the wheel arch to create a low-lying coupe style.
The exterior design of ET7 pays more attention to fullness and slenderness, and the front face adopts an optimized X-Bar design, cancels the traditional chrome decoration, and the replacement surface design is also the re-evolution of the family design gene, leading the new family design, more suitable for the administrative high-end car.
More worth mentioning, the two also integrate the two levels of "intelligence" and "beauty" in the design, the design of the Zhiji L7 integrates the roof support for the three Carlog cameras shot in billions of pixels, and the intelligent lighting system DLP + ISC before and after the body, and ET7 also pioneered the layout of the tower intelligent driving sensor on the roof, both of which broke the traditional car-making ideas and created a new wave.
And we turn our attention back to the interior cockpit, ET7 inherits the design concept of the second living room, using a wrap-around cockpit, using a floating screen design, hidden air outlet, dome-type glass roof and the use of renewable rattan Karaun material, highlighting a delicate and simple cockpit space, the main administrative style.
The L7 uses cross-screen interaction, four-zone independent sound field, baby-class eco-friendly cockpit, semi-aniline leather cladding and solid wood trim panels from lake lake Como on the wood trim panels, highlighting the pure and high-end cockpit experience.
At present, everyone is concerned about the air quality in the car, L7 and ET7 are equipped with intelligent fragrance and air purification system, in addition, L7 also uses a dedicated front-end site, which can ventilate, deodorize, remove aldehyde, and purify the interior parts, and also use a customized high-efficiency aldehyde remover, and the air standard of the new car can reach the net odor state after 182 days of use by other model users.
We see that whether it is the exterior design or the expression of the cabin inside the car, it undoubtedly reveals the common solutions of the two for high-end cars, such as the application of high-end materials and new environmentally friendly materials, while the linkage interaction of L7 inside and outside the cockpit is more bold.
Third, the chassis control comparison: L7 emphasizes sports, ET7 bias is comfortable
The pure electric drive method given by electric vehicles also brings more driving pleasure.
NIO has been using a self-developed system in the field of electric drive systems, and ET7 has also become THE first model of NIO equipped with a silicon carbide electric drive system, with a maximum power of 180kW in the front permanent magnet synchronous motor and 300kW in the rear asynchronous induction motor, which makes the ET7 accelerate to 3.8s after matching.
In addition, the ET7 series is equipped with active air suspension and 4D intelligent body control as standard, when the speed reaches the limit, the maximum dynamic drop is 10mm, and the fusion camera and high-precision map data can also actively adjust the suspension damping system by sensing the road environment in advance, bringing a more comfortable driving experience, and we will also bring more detailed evaluation to everyone in the follow-up test drive.
The L7, positioned as a performance flagship true smart sedan, is naturally "not to be outdone". Zhiji L7 is equipped with "four-wheel drive + four-wheel steering", the front and rear axle drive system has a total power of 425kW, a torque of 725 N·m, the measured 100 km acceleration is 3.87 seconds, the 100 km brake is 32.69 meters, not only the rush out but also the brake is firm, the brake performance is stronger than the ET7. And with the blessing of the international patented speed direct cooling technology, the whole vehicle can achieve more than 10 consecutive catapults, which is beyond the reach of most electric vehicles.
The Zhiji pays more attention to the adjustment of the chassis, L7 adopts an all-aluminum chassis, equipped with four-wheel steering with a two-way maximum of 12 ° and CDC electronic control shock absorbers, and the development of the Zhiji team has also created a new cooperation model, the structure and hardware configuration of the entire chassis are jointly selected by the Liams Forward-looking Engineering Team and the Zhiji Team, and jointly developed and adjusted.
As for the reason why the L7 does not use air suspension, the air suspension is mainly to adjust the height of the chassis, but on the L7, the chassis itself is already very low, even if the air suspension is used, it can not bring too much room for descent. And sedan models that pursue performance and extreme handling (such as RS, M and AMG performance cars) often do not use air suspension, so in general consideration, air suspension is not used, but CDC shock absorbers are used.
L7 is a full range of real vehicle tuning and verification by Williams engineers on suspension K&C characteristics, spring and anti-roll rod stiffness, CDC shock absorber damping, four-wheel steering calibration, tire characteristics, etc., including the actual regulation of high-speed loops, control roads, mountain roads and off-road roads.
Thanks to the 12-degree maximum steering, at low speeds, the L7 steering diameter can reach a minimum of 10.8 meters, which is smaller than the golf turning radius, the handling is very flexible, and the narrow road driving in the urban area is very friendly to the driver; and after Williams tuning, the Zhiji L7 can achieve the measured steady-state maximum lateral acceleration of 0.968G, and the elk test of more than 80km/h, the limit is super high, and the driving control is super stable.
Judging from the current publicity rhythm of the two cars, the L7 is adjusted by the Williams forward-looking team, which emphasizes more sports; while the ET7 is more inclined to comfort according to weilai's consistent style.
Fourth, the intelligent cockpit: L7 triple screen is more scene-like, ET7 AR/VR is more imaginative
From the perspective of real cars, Zhiji L7 adopts a three-screen interconnect design, and the car adopts a 39-inch giant screen with a 12.8-inch AMOLED 2K central screen, using a T-shaped layout.
The cockpit team created a "boundless" interaction concept, that is, from the beginning of development, the three screens were not used as separate single function screens, but as a composite screen for overall development. The underlying layer of the IMOS system adopts a multi-core heterogeneous distributed technology architecture, which aims to achieve multi-screen linkage.
L7 screen interaction also innovates many applications, based on the concept of SOA atomization architecture, to achieve cross-domain integration, unique. For example, L7 to create IMAD air pilot interactive mode, intelligent driving and map information to do integration, 5G network and three billion pixel cameras located on the roof of the car to form a set of Carlog system, through the master template clip and one key to share to the social platform, while DLP can project the desired picture; outside the car DLP + ISC intelligent car language can also open up the interaction domain, inside and outside the car linkage.
The ET7 adopts the interactive design of the NOMI as the core, including the 12.8-inch AMOLED central control screen, the 10.2-inch HDR digital instrument, the rear 6.6-inch HDR multi-function control screen, and the HUD system.
The highlight is that ET7 will also be connected to the AR and VR equipment jointly developed by NIO and partners, in terms of entertainment and audio, L7 is equipped with a Carlog system, which is edited through the master template and shared to the social platform with one click, while DLP can project the desired picture, more imaginative.
On the sound system, the ET7 will be equipped with 7.1.4 channel Dolby Atmos standard, equipped with 20 speakers, 1000W power amplifier output, while the L7 is equipped with 22 speakers in the whole car, 1120W power amplifier output, L7 audio features, is that it can achieve a variety of ambient sound effects through customized software algorithms, more can restore the real sound.
Fifth, intelligent driving: L7 full standard WITH ET7 support subscription
The development of intelligent driving has also become another benchmark for high-end electric vehicles.
For example, the NAD system installed by NIO on ET7 and ET5 models is also composed of NIO Aquia supersensitive platform and Adam supercomputing platform.
Among them, the Aquila supersensitive platform includes 33 sensors, including 11 8-megapixel high-definition cameras, 12 ultrasonic radars, 1 lidar, 5 millimeter wave radars, etc., and adopts a roof watchtower sensor layout, while the computing power platform is equipped with 4 NVIDIA Orin chips with a computing power of 1016TOPS.
The IM AD driver assistance system equipped with the L7 is equipped with 12 cameras, 5 millimeter wave radars, 12 ultrasonic radars, and can be compatible with two lidar software and hardware upgrades, and the computing power platform is also upgraded to the Compatible Orin platform after the Xavier platform.
At the same time, Zhiji Auto IM AD intelligent driving system has completed the challenge of "full intelligent driving" measured in 5 cities of Shanghai, Suzhou, Chengdu, Hangzhou and Guangzhou, proving the strong strength of its artificial intelligence super algorithm and the whole process data drive as the technical route. And under the continuous data training, the vehicle will become more and more intelligent, and the intelligent driving ability will continue to be automatically and iteratively upgraded, which is not something that Weilai can achieve simply by piling up computing power.
In terms of business model, ET7's NOP Plus and NAD system hardware are standard, but NAD software functions will be provided in a monthly subscription model, and the service fee is 680 yuan per month.
The L7 angel wheel users are using a lifetime free subscription model, it is worth mentioning that L7 also uses the interactive mode of trust enhancement experience, through the screen, sound, projection and seat belt vibration, the use of WIFI signal signal logic, a total of three levels, in the experience can give users to do a gradient expectation, will not produce a fault or abrupt exit experience, enhance the user's confidence and security.
(You can take a look at our experience of IM AD assisted driving video: https://www.xchuxing.com/article/35521)
L7 can achieve the state of functional use at the time of delivery, we also actually experience IM AD in Suzhou, and have better performance in the city to identify slow cars, crosswalkers, traffic light intersections, congestion and overtaking lane changes, etc., and the passability is also strong, and we are more looking forward to the actual performance after its delivery.
Sixth, the configuration comparison: the high-end configuration of the two cars are piled up
From the configuration comparison, we see that ET7 and L7, as local high-end brands, are also trying to compete with traditional joint venture high-end brands with a new attempt.
For example, when we compare the BMW 5 Series in terms of configuration, we find that the ET7 and L7 are better in terms of performance configuration, comfort configuration, high-end configuration, and AV entertainment.
ET7 comes standard with air suspension, electric suction door, NAD sensor hardware, high-performance power of 3.8s dual motors; The L7 comes standard with a more interactive lighting system, Carlog, a 39-inch giant smart scene screen, CDC electronically controlled damping system, and a master chassis built by the Liams Forward Engineering team.
Whether the two can leverage the pattern of the traditional high-end medium and large market, we will wait and see.
As the only medium and large high-end pure electric sedan of its own brand, the L7 and ET7 cars have a lot in common, first-class design standards, excellent hardware levels and high-end brand tone.
However, there are many differences between the two cars, such as the L7, which focuses on performance and control, and at the same time integrates more multi-interactive systems inside and outside the car, which is more suitable for young people who currently pay attention to social interaction and taste, while ET7 is more full and simple in appearance and cockpit layout, and is more inclined to high-end administration as a whole, more suitable for business travel needs and users pursuing technology.
