Only half a year after its listing, Dongfeng Citroen Versailles C5 X has won the honor of "2021 China's Top Ten Body" with its high safety and quality; Thousands of Versailles C5 X set sail for overseas sales, breaking the record of the DPCA company... Today, Xiaobian will reveal how the Dongfeng Citroen Versailles C5 X was built into "global quality"?
As the first new flagship model of the Citroën brand "Made in Chengdu and Sold Worldwide", the "global quality" of the Versailles C5 X is mainly reflected in the three key points of "global standards, global supply and global factories".
Start with the architecture and look forward design to meet global standards
Just as software design is inseparable from architecture, the performance of automotive products and the construction of intelligent technology also need advanced architectural support. 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 not only meets the domestic C-NCAP and C-IASI crash safety standards, but also develops the EuroNCAP European safety standards in a targeted manner, and meets the higher standards formulated by the SAINTONIS Group, providing consumers with a high level of global safety and quality for every trip with all-round and dead-end safety protection.
For example, the 8AT hand automatic transmission comes from Aixin, which is recognized in the industry for its outstanding performance; The master chassis tuning matches KYB OEM and is powered by Citroën's 20-patented PHC Adaptive Hydraulic Stabilization Technology shock absorbers, combined with BASF's shock absorber sleeves, to provide a gentle and comfortable driving experience.
As we all know, the factory is the starting point of the "life" of the car, and the intelligent and automated level of production and manufacturing has a profound impact on product quality to a certain extent. Versailles C5 X production base - Dongfeng Group and STEELTIS Group's "global new generation benchmark factory", the four major process workshops use intelligent equipment to achieve highly automated production.
Stamping: Forged Versailles C5 X reinforced iron bone. 80% of the versailles C5 X is made of high-strength steel and advanced high-strength steel as materials. Through the stamping workshop fully enclosed high-speed automatic stamping line, the four-sequence production mode is used to realize the fully automated production of stamping, and the stamping accuracy control is efficiently guaranteed to be within 0.01mm to ensure the rigidity of the body.
Welding: 100% automatic welding to ensure that the body is beautiful and strong. In the intelligent welding workshop, 491 robots work synchronously, and the welding automation rate reaches 100%. With an oversized hexahedral horizontal rotary table, one production line can produce six large body parts at the same time, and the production efficiency has increased several times.
Advanced technology of welding production - laser welding technology, with a maximum of 6000W high-power laser beam as energy for the body sidewing and roof for tight seam high-precision welding, coupled with advanced structural glue new process to ensure that the Versailles C5 X body is beautiful and strong. In addition, online monitoring of body-in-white geometry can also effectively avoid the outflow of non-conforming products, ensuring the consistency and high quality of the body.
Not only that, after the welding process is off the line, the factory will regularly randomly select a body for a broken test to ensure the integrity of the product solder joints and the safety and quality of the vehicle.
Coating: Energy saving and environmental protection to create a clean cockpit. The painting workshop integrates leading processes such as no-stroke coating and green pre-treatment, and is equipped with 68 robots to achieve high-quality fine painting process inside and outside the vehicle. Taking into account the technology and environmental protection of the coating process, not only for the Versailles C5 X to provide high-quality water-based topcoat coating body, the silane process used in the old phosphating process saves energy consumption of up to 50%, no heavy metal emissions, bringing customers green and healthy high-quality clean cockpit.
Final Assembly: Strict checks ensure that the Versailles C5 X is consistently reliable. The final assembly workshop achieves a parts collection rate of up to 95% through advanced logistics mode, which not only improves production efficiency, but also ensures zero errors in the final assembly operation of Versailles C5 X parts. The fully automatic fitting and tightening of the body chassis, the monitoring and traceability management of the whole process of key assembly parameters, also further realize the high quality of the vehicle assembly.
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 a dedicated runway with a total length of 4.5 kilometers in the factory, providing 100% runway testing and 21 full-road condition road tests, ensuring that every Versailles C5 X after the launch of the production line can maintain consistent reliability.
In fact, in the vehicle development stage, Dongfeng Citroen also has its own unique skills. That is, in addition to the conventional "high temperature, high altitude, high cold" three high experiments, Versailles C5 X also needs to go through the open road user simulation "catching insects" experiment with a total mileage of more than 2 million kilometers, and put a large number of experimental vehicles into the actual road for "fatigue testing" to find out the problems missing in the development, so as to improve the quality and reliability of the vehicle.
