A good car, not only loves its accompanying companionship, but also has to be a practical and safe intimate escort.
In the Chinese market, the French joint venture models produced by DPCA are known for their solid and durable leather, and they are well-known in terms of body materials and manufacturing processes.
"Turn the tide against the tide, and help the building to fall." As a work to promote the return of French brands to the mainstream, versailles C5 X insists on polishing the brand tone and product label, and opens a comprehensive renewal of strength from the inside out.
Because of this, it not only has a satisfactory performance in the domestic and foreign markets, but also stands out in various identifications and tests of industry institutions, and has successively won the honors of "2021 China Top Ten Body" and C-NCAP "Five-Star" safety rating.
Of course, excellent word of mouth and product hard power are inseparable from advanced manufacturing technology, born in the Chengdu factory of DPCA, the global production base of the highest technical specifications, only to refine the conscience quality of "Chengdu made global sales".
Today, the author leads you to the "Versailles frontline" to reveal how the Versailles C5 X has achieved high-quality construction in a short period of time, and how it has won the overall praise of experts and fans inside and outside the industry.
Excellent software and hardware without exception are inseparable from reliable architecture support, the car as a high-precision industrial products, in the process of product performance, intelligent technology construction process, the degree of dependence on architecture is self-evident.
The FAIRANTIS Group's EMP2 V3 modular architecture, designed to meet high safety standards in line with different road conditions and environments around the world, is the cornerstone of versailles C5 X's global quality.
Versailles C5 X can not only easily meet the domestic C-NCAP, C-IASI collision safety standards, but also carry out targeted development in accordance with EuroNCAP European safety standards, fully achieve the higher standards formulated by THE DELLANTIS Group, and provide consumers with a high level of safety and quality with a high level of global safety and quality.
Efficient and thoughtful R&D concepts collide with each other, often winning the effect of 1+1>2.
In order to ensure that every car owner enjoys a high-quality car experience, all parts procurement system of versailles C5 X are derived from first-class global professional suppliers.
For example, the 8AT gearbox is derived from the famous Aisin Seiki, the tuning and calibration of the master chassis is found by KYB, and together with Citroën's 20-patented PHC Adaptive Hydraulic Stabilization Technology shock absorbers and BASF shock absorber sleeves, it can provide maximum comfortable driving experience and agile and calm handling performance.
In addition, the Versailles C5 X is also very skilled - the new ESP 9.3 body stability system is provided by the world's top 500 companies Bosch, Germany, in the event of oversteering or understeering and causing accidents, esp system can achieve rapid response in a very short period of time and limit the skidding of the vehicle, effectively reducing the probability of accidents.
Dongfeng Citroen starts from the source, and its initiative to strictly identify and select first-class suppliers is second to none in the industry. We have reason to believe that the Versailles C5 X, a "full-body brand", will surely become the first choice for customers to enjoy exceptional quality travel.
The factory is the starting point of the car's life and the final integration of the components, where the level of intelligence and automation of the production assembly has a decisive influence on product quality.
Versailles C5 X, the world's only production base - DPCA Chengdu factory, is dongfeng group and STEELTANIS group "global new generation benchmark factory", the four major process workshops using industry-leading intelligent equipment, to achieve highly automated production, most of the process steps and key nodes are in strict control of the machinery and equipment "labor", the error rate is much lower than the old assembly line of the manual era.
In the stamping process, the Chengdu plant selected the industry's top equipment and operation control software for the high-strength steel and a variety of high-performance steels used in Versailles C5 X to achieve a satisfactory balance between production efficiency and yield rate to the greatest extent.
In addition, two industry-leading fully enclosed high-speed automatic stamping lines adopt a four-sequence production mode to achieve fully automated stamping production, ensuring that the stamping accuracy is controlled within 0.01mm.
In the welding process, 100% automatic welding ensures that the body is beautiful and strong, 491 robots work synchronously, and the welding automation rate reaches 100%. On the other hand, relying on the unique ultra-large hexahedral horizontal rotary table in China, the production line can produce six kinds of large body parts at the same time, and the production efficiency is doubled.
It is worth mentioning that the welding link adopts the most advanced laser welding technology at present, and the high-precision welding of the body sidewall and roof is carried out with 6kW high-power laser beam as energy, supplemented by advanced structural glue new technology to ensure that the Versailles C5 X body is regular and strong.
The online monitoring mechanism of body-in-white geometry can also effectively avoid the outflow of non-conforming products and ensure the dimensional consistency of the body-in-white.
Not only that, after the self-welding process is off the line, the factory will regularly randomly select a car body for a broken inspection experiment to ensure the integrity of the product solder joint at all costs.
In the painting process, the Chengdu factory tries its best to uphold the concept of energy saving and environmental protection, creates a clean cockpit - the painting workshop integrates leading processes such as free middle coating and green pretreatment, and is equipped with 68 robots to achieve high-quality fine painting process inside and outside the vehicle.
The technical and environmentally friendly coating process not only provides the Versailles C5 X with high-quality water-based topcoats to coat the body, but also saves up to 50% in energy consumption.
In the final assembly process, the Chengdu plant of Dongfeng Citroen Automobile is in a leading position in the industry in the application of new technologies such as process integration innovation, intelligence, and full quality inspection. And the workshop through the advanced logistics mode to achieve parts collection rate of up to 95%, can achieve high-quality assembly of the vehicle, effectively ensure that the Versailles C5 X parts assembly operation zero errors.
After the assembly is completed, each Versailles C5 X must also pass 241 strict inspections such as vehicle initialization inspection, functional inspection, front wheel forward speed adjustment, four-wheel positioning detection, and rain.
In addition to the quality inspection area, there is also a world-class special runway with a total length of 4.5 kilometers, providing 100% runway test and 21 kinds of road test tests for all road conditions, which can be called a very strict "final exam", and the products after successfully passing will have the opportunity to "treat customers".
It is worth mentioning that Dongfeng Citroen also hid a set of unique skills in the vehicle test stage, that is, in addition to the conventional "high temperature, high altitude, high cold" experiment, it is also necessary to go through the open road user simulation "catching insects" experiment with a total mileage of more than 2 million kilometers, and carry out "fatigue test" by putting a large number of experimental vehicles into the actual road, so as to find the problems missed in the research and development and production process and further improve the quality of the vehicle.
With global quality, it plays a strong French tone.
Dongfeng Citroen is using the greatest sincerity to create the highest quality and reliable products for users, which can be seen in its investment in a product for the Versailles C5 X regardless of cost.
Strict production and assembly process control and thoughtful detail maintenance have created the extraordinary quality and excellent user reputation of the Versailles C5 X, and opened up an exciting new situation for the future share ratio reform of DPCA.
It has to be said that the Versailles C5 X is not only a family car with a rich personality, but also a phenomenon-level product that reflects the diversification of the market and the trend of new products.
