What is a smart and variable new car?
Intelligent and variable new car is a revolutionary type of digital and intelligent vehicle. Its essential feature is the fusion of two or more different body shapes. Not only can it switch between different body types such as cars, SUVs, pickups, MPVs, etc. according to user requests in appearance, but also has a highly flexible interior space design, allowing users to freely combine to adapt to various use scenarios. Equipped with an advanced intelligent software system, it can improve the user experience through continuous software iteration, and has artificial intelligence features to better understand and meet the individual needs of users. In non-driving state, it can be transformed into a variety of living spaces according to the needs of users. Changan Qiyuan E07 is a one-car to multi-car, transforming into "SUV form" for travel, "coupe form" for commuting, and "pickup form" for loading.
So how such a smart car is made can be found in the digital intelligence factory full of technology.
Entering the Changan Digital Intelligence Factory, automated robotic arms are flying up and down, and automated robots are working in an orderly manner.
"Changan Shuzhi Factory has fully introduced new technologies, and continues to invest and innovate in the field of intelligent manufacturing." The relevant person in charge of Changan Shuzhi Factory introduced. At present, the stamping production line of Changan Shuzhi Factory’s stamping workshop has been 100% automated. It is the first steel and aluminum mixed production line of Changan’s own brand, which can flexibly respond to the production needs of different materials – steel and aluminum plates.
In the upgraded welding workshop, the automation level of the workshop has been increased to more than 95%, with a total of 185 welding stations and 471 automated robots widely distributed throughout the workshop, enhancing the accuracy of welding operations and enhancing the strength of the vehicle through the introduction of a large number of new aluminum alloy riveting processes.

"Through a series of advanced technologies, a new generation of safety body of Changan Qiyuan E07 has been created. The proportion of high-strength steel and aluminum alloy is more than 90%. All the car bodies and even the front cover are made of all aluminum alloy, which greatly enhances the lightweight of the vehicle and greatly enhances the durability and safety of the vehicle." The relevant person in charge said.
In the factory’s first fully automated flexible and unmanned die-casting production workshop in China, the five process steps of melting, die-casting, post-processing, machining and assembly are being carried out in an orderly manner. With four 7700-ton die-casting machines, Changan Qiyuan E07 has realized the integration of 163 parts into 2 parts here. The casting time is only 110 seconds. It is the first die-casting process of one mold and two pieces, which can realize the separate design of bumper parts and one-piece die-casting parts. "In this way, through the slow connection of the mechanical structure, it is guaranteed that the car will not damage the one-piece casting in the conventional collision, reduce the maintenance cost after the collision, and also reduce the weight of the Changan Qiyuan E07 vehicle with integrated die-casting technology by 20%, and the handling is more agile." The relevant person in charge said.
It is worth mentioning that in the battery workshop Changan Qiyuan E07 powerful energy nuclear source "Golden Bell Jar Battery" was born here. The battery workshop has achieved 100% automated production, and the pre-group area has been fully automated. It is the largest black light factory in Asia. The "Golden Bell Jar" battery adopts military-grade basalt nano-thermal insulation material, 100% thermal suppression, CTV integration integration technology, battery and chassis integration, improving body and battery safety, 800V high-voltage fast charging technology, giving the E07 super long battery life and ultra-fast charging, and can achieve a battery life of 365Km after charging for about 15min.
Finally, after welding, painting and final assembly, a Changan Qiyuan E07 with a length of 5045mm, a width of 1996mm and a height of 1640mm and a dual-motor four-wheel drive system with a peak power of 440kW and a peak torque of 645Nm is rolled off the assembly line. This "intelligent variable new car" with three body variable functions of "SUV, pickup truck and coupe" is expected to start at no less than 300,000 yuan.
