Not long ago, Changan held a global first-hand experience tour in Chongqing, the protagonist of this time is the first car based on the Ark architecture - UNI-V, which has maintained a high degree of attention since its launch. Through the relevant reports of the test drive activity, we also saw its outstanding performance, so why does UNI-V have such achievements, and why is it an important step to bring Changan Automobile into the 4.0 car-making era? Today I will give you a look at it together.
1. A brief review of previous test drives
In terms of appearance, UNI-V not only continues the design elements of the UNI family, but also upgrades the visual impact on this basis, or the overall appearance is more combative. Such a shape is basically no resistance to those young consumers, and it is also equipped with the only electric spoiler in its class.
The shape of the interior also continues the style of UNI-K, and the small size of the steering wheel is very much in line with its sporty positioning. The car machine system is equipped with the latest voice interaction system of iFLYTEK, which not only supports context recognition, cross-scene recognition, etc., in addition to the car machine system itself, it also supports the OTA online upgrade of the whole vehicle, which is also its biggest highlight, which means that it not only allows the car machine function to evolve with user needs, but also the performance of the vehicle can be updated and iterated with development.
UNI-V in terms of power and handling, is also very bright, 1.5T turbo engine with 7-speed wet dual-clutch transmission combination, not only daily driving can bring good ride, power output for this small displacement engine is also very abundant, mid-section acceleration still feel more adequate power reserves.
In terms of handling, the UNI-V's short front suspension and short rear suspension design makes its body very flexible, and its trackability in continuous corners is excellent, without procrastination. The control belongs to a very accurate type, and it also has the feeling of which to play. The performance of the suspension is also outstanding, and it is also equipped with a lateral stabilizer bar in the engine compartment, and two balance bars are also installed in the chassis part, which not only has a more prominent performance in the hardware structure, but also has an excellent level in tuning.
Taken together, UNI-V excels in terms of design, power matching, and dynamics, but what kind of technology gives it such strength?
2. What does the Ark architecture give to UNI-V?
The reason for such outstanding performance is because it is based on the Ark architecture, which is a platform architecture that can cover all models from A0 class to C, and is the evolutionary carrier of Changan's new car manufacturing technology. Under this architecture, it can bring higher-order autonomous driving layouts, more advanced electrical architectures, and diverse power combinations.
Appearance: More sporty, flexible platform
For the design of the shape, the Ark architecture can provide flexible and changeable sizes with home, including front and rear overhangs, wheelbase can be flexible and changeable, which also brings more room for designers to play. The more athletic nature of UNI-V has a lot to do with its shorter front-to-back overhang.
In addition, the low body with large size rim, hatchback style design and the current unique electric spoiler of the same class, these conditions make it more characteristic of a sports car, can have these conditions at the same time, Audi A7 is counted as one.
Structure: Lower center of gravity, more conducive to driving
Not only the style is moving, its overall center of gravity is also lower than that of ordinary cars, the inclination angle of the power arrangement is optimized from 7.5° forward to 10° backward, and the center of the crankshaft of the engine has also dropped by 12mm, these changes have reduced its overall center of gravity by 20-65mm, in driving, we can best reflect the wider field of view, driving sitting posture is also lower.
Security: Smarter and more secure
For safety, the Ark architecture can be equipped with a higher-level automatic driving assistance system, and the layout of hardware such as sensors and controllers is more in line with the needs of future development. At present, for the core part has reserved the location of 36 sensors, and it is also equipped with high-precision maps, 5G-V2X modules and 2 high-computing controllers, etc., it is also the first Chinese brand to achieve L3 level automatic driving mass production at this stage, of course, as long as future regulations allow, it can be directly upgraded with more scenario-based automatic driving functions.
At present, UNI-V already has the automatic driving assistance system, in addition to the full speed adaptive cruise and lane keeping that we are familiar with, it also has the driver trigger lane change function, the driver can dial the steering lever or issue a lane change command through voice, and the vehicle completes the lane change process under the condition of ensuring safety.
In terms of autonomous driving assistance system, UNI-V is also equipped with a smart recommendation lane change function, which is a function that the system will judge road information based on the information captured by sensors and provided by the online map, and recommend a more smooth driving lane for drivers.
Power: Full of power, precise control, excellent tuning
Finally, talking about power and control, the power version that the Ark architecture can be compatible with is very rich, with displacement from 1.2-2.0L, 48V low-voltage hybrid, high-voltage hybrid and plug-in hybrid can be assembled on this platform, and the gearbox with it is also as many as 8 kinds. The UNI-V uses blue whale's new generation NE1.5T high-pressure direct injection engine, matched with blue whale's 7-speed wet dual-clutch transmission, which has a maximum power of 138 kW (188 hp) and can reach a maximum torque value of 300 Nm at 1500 rpm.
The power performance of this engine is still very good among the engines of the same displacement, and the 7-speed wet dual-clutch transmission with it has a good daily shift smoothness. In terms of handling, the UNI-V feels good, the steering is very precise, and the rear of the car follows well, which is very in line with its own movement positioning. The performance of the suspension belongs to the fact that while ensuring a certain toughness, it can also bring enough support to the body when cornering.
The satisfactory performance in terms of dynamics is also due to the Ark-based architecture, under which it not only reduces the vehicle's center of gravity, but also reduces the body tilt gradient of the new generation by 25%. From another point of view, its body height is 1430mm, the front and rear wheelbases are 1576mm and 1586mm, compared with the previous generation of BMW 3 Series, its height is lower, the front and rear wheelbase is wider, coupled with excellent chassis tuning, so that it faces the corners, the body roll is smaller. In terms of steering setting and tuning, the UNI-V's steering swing lag time is 25% shorter than that of ordinary models, which is why it feels more flexible in handling and the front of the car responds faster.
summary:
UNI-V is the first model launched based on the Ark architecture, and after the test drive, everyone gave full recognition to this car. Through the first contact, it shows the excellent performance that the Ark architecture has brought to UNI-V in all aspects. Especially in the dynamic links, the more flexible and changeable advantages of the Ark architecture allow UNI-V to have a more sporty appearance, but also to bring better handling and driving texture.
In fact, based on the Ark architecture to create is also to UNI-V to bring more possibilities, the future in addition to allowing it to have a higher level of automatic driving functions, Ark architecture compared to other platform architecture another major advantage is its OTA upgrade, so the official also called the smart growth of electrical and electronic architecture, with the continuous improvement of the demand of car owners, it can also provide more customized services, which is just like our smart phones, a variety of functions with the change of everyone's needs and change.
