“What the people need, Wuling makes,” this is the most well-known phrase for consumers about Wuling. Seemingly a simple phrase, it reflects Wuling’s strict requirements for quality and its attitude of constantly improving its overall strength. Making cars is not an easy task, don’t underestimate the Wuling Rongguo, which sells for just a few thousand yuan. When it comes to safety, its performance is absolutely not sloppy. It’s usually difficult to see the internal structure, design, and various components of a car. This time, the Wuling Rongguo fully satisfied everyone’s curiosity by “hurting itself,” dismantling it completely, allowing us to once again take a close look at the “inner beauty” of the Rongguo.
Wuling understands the importance of the platform, and relies on Wuling’s new energy core research and development strength to create the Wuling Bengu based on a brand-new native pure electric architecture. This forms a clear difference from the current market, where most pure electric small cars under 100,000 yuan (13990$) are oil-to-electric products, and the thinking of shrinking big cars. Wuling’s original pure electric small car architecture has different strengths in space, safety, driving, and three-electric.
1. Space Wuling Bingguo is based on a new native pure electric architecture, ensuring reliability and passability of components, maximizing the use of space to create a larger interior space for consumers, all for a better driving experience.
Let’s take a brief look at the styling design again. The Bingguo styling is simple and round, with the longest wheelbase in its class: the body size of the Wuling Bingguo is 3950/1708/1580mm, with a wheelbase of 2560mm. Thanks to the front-wheel drive pure electric platform, the Bingguo maximizes space utilization for users, achieving a longitudinal and transverse space utilization rate of 67.7% and 77.6% respectively, both higher than the same level. It can also meet various common travel scenarios, such as the placement of child safety seats and carrying strollers. The Bingguo adopts a front-through main and co-driver design, making the central aisle of the cockpit more spacious and increasing legroom for front-row members, which is extremely convenient when getting in and out of narrow spaces.
The Bingguo also has a unique sunken trunk, with good depth and clearance height. The “sunken” trunk forms an “upper and lower” large space layout, allowing for layered storage. The rear seats of the Bingguo support a 5/5 split fold, with a total folded space of 790L, enough to accommodate 7 20-inch carry-on suitcases at the same time. Even when fully loaded, it can accommodate 4 20-inch carry-on suitcases. The spaciousness of the trunk has been fully confirmed in the test drive experience. The Bingguo may be small, but its trunk is really capable. Of course, we haven’t overlooked other storage spaces inside the car. The Bingguo has 15 storage spaces including phone slots, cup holders, and glove boxes, achieved through full excavation of the door panels and dashboard. The hidden double hooks can be used to hang milk tea, umbrellas, and snack bags, perhaps a very thoughtful design unique to Wuling. Second, high safety Although the car is small, its safety performance cannot be low. Wuling has always believed that the safety of new energy small cars should be comprehensive and holistic. Safety of the three electric components and the body is also crucial. In addition to the visible safety features such as front and side airbags for the driver and front passenger, ESC, and AUTOHOLD function, Wuling Bingguo also considers the later repair economy and service life, by lowering the user’s later costs as much as possible through more reasonable design and more reliable quality. What specific safety features are there, let’s take a look below:
1. Front Energy Absorption Box The front end of the Binguo longitudinal beam is equipped with an energy absorption box, which is designed to improve passive safety of the car and reduce repair costs in low-speed collisions. The energy absorption box is easily deformed in a collision, effectively absorbing collision energy. In low-speed collisions, the energy absorption box deforms to absorb energy, minimizing damage to the body’s longitudinal beam. This allows for easy replacement of the energy absorption box in low-speed collisions without the need for major repairs to the longitudinal beam.
2. The Bingguo adopts a full-frame subframe and a new three-layer energy-absorbing structure, with a more reasonable load distribution. In a frontal collision, the energy absorption efficiency of the front end is higher, increasing energy absorption efficiency by 15% compared to models with only two-layer energy-absorbing structures. 3. The Bingguo adopts a five-ring body structure, increasing body stiffness and improving NVH performance, while also quickly transferring collision energy during a collision to reduce cabin intrusion and protect passenger safety.
The body of the Bingguo car is made of high-strength steel, with a ring-shaped cage structure. 25 key protection parts such as the passenger compartment, battery compartment, and door beams use ultra-high-strength steel of over 1500MPa, forming a hot-formed door ring that can withstand higher strength and pressure, improving the body’s torsional rigidity and safety. At the same time, the hot-formed door ring can also improve the body’s sealing and shock absorption performance, reduce noise and vibration, and improve driving comfort. In terms of the three electrical components, the quality of the three electric technologies is important for a new energy vehicle, but safety is even more important. Without safety, any performance is just talk. Wuling Bingguo uses God-refined batteries, three-in-one water-cooled flat wire motors, and other three electric hardware to continuously optimize safety, endurance rate, and performance stability, ensuring safe travel.
1. Non-flammable battery core The original battery core “Ask Top Technology” optimizes and innovates from the internal structure, solid-liquid interface, and material system of the battery core. The innovative L-shaped pole ear replaces the traditional U-shaped pole ear, avoiding the sinking of the pole ear due to vibration, and the contact pole piece causing internal short circuit; the top of the pole piece adopts insulation protection layer and ample overhang design, eliminating self-discharge and lithium deposition at the top. In addition, a ceramic layer is used for further heat control, ensuring that the battery core does not short circuit, leak, decompose lithium, or catch fire. In the test at the China Automotive Center, the battery core of the Bingguo undergoes 40% compression deformation, one-third depth needle puncture, normal charge and discharge, and vertical steel needle puncture without the phenomenon of fire or explosion, high-temperature short circuit, and other tests, the battery core did not catch fire.
Battery Pack Safety Shenlian battery adopts the original MUST structure multifunctional integrated design. With the same amount of structural materials, the strength is increased by 60%. It uses high-level flame retardant and temperature-resistant materials to seal the entire battery pack. It is not afraid of high temperature, fire, water and dust intrusion, and cold and hot shock. A Shenlian battery pack can pass three or even four rigorous tests in one go and obtain authoritative certification from China Automotive Research Institute.
Wuling Bingguo also focuses on structural innovation, pioneering the use of the “main wing” design concept of large aircraft in structural design, integrating structural beams, side panels, and thermal management to achieve ultra-lightweight, high-strength structure and thermal management functions. At the same time, the MUST design of the Shenlian battery breaks through the contradiction of high integration, high strength, and non-removability and maintainability in the current battery industry, realizing the removability and maintainability of key components within the battery system. Under the premise of ensuring battery safety and performance, each battery can be individually repaired and replaced, saving money and being visible to the naked eye. IP68 protection level + high standard battery system testing The Shenlian battery uses the highest level of flame-retardant V-0 silicone-based temperature-resistant sealing material, which can effectively resist external water and dust intrusion and thermal shock, and has IP68 protection level.
During the development of the Godly Battery, a battery pack underwent comprehensive testing including vibration, immersion, dynamic impact resistance, and charge-discharge cycling. It also underwent extreme verification such as temperature variation, immersion, and high temperature needle puncture to ensure it does not catch fire or explode, ensuring the safety of the user. The Wuling Baojun also employs over 240 safety regulations and over 80 fault warnings, allowing for continuous safety inspection throughout its entire lifecycle. In the event of battery collision, puncture, or overheating, it will actively alert the user.
50kW three-in-one water-cooled flat wire motor The Wuling Binguo 410km Lingxi Supreme Edition is equipped with a new three-in-one water-cooled flat wire motor, which has a 20% increase in slot fill rate compared to round wire motors; the contact area between flat wires is larger, with better heat conduction, bringing stronger heat dissipation capability.
Flat wire motor power density increased by 0.8 kW/kg, and the high-efficiency range expanded by 11%, resulting in the motor’s highest efficiency >96%. At the same time, the flat wire motor has better rigidity, has a certain inhibitory effect on noise, and can bring better NVH performance; In addition, the electric drive system is designed to be lightweight as a whole, reducing the weight by 3kg compared to the round wire motor, which also increases the driving range. Fourth, driving experience The Wuling Rongguo is a solid and practical commuter car, and this positioning is completely correct. But Wuling doesn’t want it to seem mediocre just because it’s a commuter car. Comfort and convenience are what Wuling always pays attention to. First, let’s look at the driving visibility. We all know that a broader driving visibility can bring a more transparent feeling and reduce blind spots in the driving visibility. Rongguo lowers the height of the dashboard and the lower edge of the windshield, shortening the front blind spot by about 1 meter compared to other models. At the same time, Rongguo uses larger rear door glass and side door glass to improve interior lighting and transparency, further enhancing the user’s driving experience.
The rear suspension of the Bingguo is still a torsion beam structure, but this does not affect the comfort of the Bingguo too much. Because the Wuling Bingguo has changed the rear torsion beam from an open beam design to a closed beam design on the 410km Lingxi Premium Edition, the torsion beam stiffness has increased by 41%, the load-bearing capacity has correspondingly increased, thus reducing vibration.
The springs and shock absorbers of the Binguo adopt a separate layout, which provides a wider adjustment range compared to the integrated springs, resulting in better overall vehicle performance and comfort. In addition, the Binguo’s chassis tuning style leans towards firmness, balancing stability and comfort, resulting in a smooth driving experience with improved lateral support.
NVH is an important indicator of a vehicle’s comfort. The front subframe of the Wuling Bingguo is connected at the front two points and supported by the rear two points, with secondary vibration isolation. The rear arm support is pressed into an independent aluminum alloy bracket and then connected to the subframe with bolts. This flexible connection effectively reduces body vibration and isolates noise transmission compared to rigid connections in the same class of vehicles. Additionally, both the front and rear doors of the Bingguo have two complete sealing strips, and the material of the front and rear wheel covers is non-woven fabric + PP + PET + non-woven fabric, further enhancing the overall NVH performance of the vehicle.
During daily driving, tunnels and scenes with significant light changes are often encountered. The Wuling Bengu is equipped with automatic headlights, which adjust the brightness of the lights according to the changing light. Similarly, it also has automatic wipers, which help drivers focus on driving in rainy conditions by automatically adjusting the wiper speed based on the amount of rain. In special situations such as encountering water trucks or sudden rainfall, it also performs well. The Wuling Bengu, with its down-to-earth pricing, has once again gained a place in the hearts of consumers. This breakdown also allows us to fully understand the Wuling Bengu’s internal qualities in terms of space layout, comfort, and especially safety protection. The performance of this national-level small car is impressive.
