Wuling Xingguang S, a "large space SUV for home use" built on the Tianyu architecture D platform, relies on S level safety ,
As the only authoritative professional selection in the field of chassis in the automotive industry, China's Top Ten Chassis Selection (10 BEST Chassis) is known as the "Oscars of the Chassis Industry". The selection of this award is through an expert selection team and Objective evaluation data has become the most influential new technology display and communication platform for chassis. While providing consumers with reference standards for car purchase, it has greatly promoted the research and development and application of basic chassis technology in my country, and successfully led the trend of cutting-edge automotive chassis technology.
The selection of "2024China's Top Ten Chassis" went through multiple rounds of rigorous screening including audition voting, online preliminary evaluation, and actual vehicle defense. During the actual vehicle defense session, industry experts, media representatives, and user representatives were specially invited to participate in depth to ensure the ecological fairness of the selection; a dynamic and static dual selection was also set up to verify the comprehensive technical level of the chassis, and assessments were conducted from both subjective and objective dimensions to ensure The scientific and rigorous evaluation system ultimately selected the top ten award-winning models of the year.
Active and passive dual-channel safety design, stable S level safety
Wuling StarlightS adopts a six-ring high-strength steel body structure and "full-frame front subframe" energy-absorbing technology to improve the strength of the body; the high-strength steel coverage rate of structural parts exceeds82.5%, far exceeding the same level. The vehicle has stronger resistance to deformation and higher safety.
In addition, through the development of a full-scenario, full-chain simulation and test verification system, Wuling Starlight S has achieved the ability to pass without loosening the chassis under misuse conditions 60km/h. No deformation, no deformation, no cracking ; Wuling Starlight S's agile braking system can also achieve an emergency braking distance of 100 kilometers <38m, with built-in pressure of 0.15s, significantly Improve brake soundIt is equipped with 0.5g backup braking deceleration to achieve multiple guarantees of braking safety; the ESC electronic stability control system integrates 12 sub-functions, Make the vehicle more stable and safer, and provide users with invisible care.
Innovative virtual and real simulation verification, rigorous testing to achieve S level reliability
Wuling Starlight S’s chassis is based on the accumulation of 29 million million user data, and relies on Guangxi’s first independent intellectual property rights to combine physical and virtual dual test sites. The virtual test site elevation The error is less than 1.0mm, it has a 2×2mmCRG grid, and adopts the "three-dimensional integration" of simulation design Relevant equivalent durability system innovation, equivalent accuracy 95%, accurately simulates actual vehicle scenarios; the vehicle test site is built with 62 types of typical characteristic roads, which can simulate < span>300Multiple user driving scenarios.
After undergoing a rigorous test and verification system, Wuling Starlight S passed the test including the vehicle 24 channel, subsystem 12 channel, 4 Columns and component levels exceeding 2200 hours Durability bench verification; the vehicle test passed 33 types of durability characteristic road tests with high precision related to user usage scenarios, as well as the rigorous assessment of ±40 degrees of extreme cold and heat. More than 500,000 kilometers of high-mileage intensive road testing finally created the "Volume King" in the same class market.
Ultimate energy management system, S level energy efficiency achieves fuel consumption per 100 kilometers 3.9L
The chassis of Wuling Starlight S adopts a hybrid design of high-strength steel and aluminum. It has light unsprung mass and is crash-resistant and reliable. Through the multi-level topology technology that combines hybrid lightweight and concept lightweight, Achieving 15kg weight reduction compared with vehicles of the same class.
In terms of reducing drag, Wuling Starlight S uses a caliper drag force as low as 0.9N·m, which is less than 0.8 N·m’s low-traction rolling resistance bearing reduces driving resistance and improves vehicle endurance compared toThe conventional plan adds 10km; "0 degree" flat chassis design and ultra-low wind resistance wheels, reducing the vehicle's wind resistance coefficient by 0.004Cd; Wuling Starlight S braking energy recovery intensity can reach 0.3g, and the recovery efficiency can reach 95%. Each braking event is converted into a bonus for battery life, achieving Double upgrade of efficiency and environmental protection.
Under the complete set of excellent energy flow management system, Wuling Starlight S system resistance is reduced by 2% compared with vehicles of the same class. Every acceleration and deceleration is a reflection of efficiency and The perfect combination of intelligence.
Solid chassis hardware combination, S level of comfort
Wuling Starlight S, built on the Tianyu architecture D platform, adopts front and rear independent suspensions with leading quality-price ratio in its class in terms of chassis hardware to ensure that it meets Hardware basis for comfort requirements. Based on the scene-based dynamic and static stiffness decoupling design, the energy absorption efficiency is increased by 15%, the vibration is filtered more thoroughly, and the driving comfort is better.
The MacPherson independent front suspension uses vulcanized integrated bushings through the front stabilizer bar, which eliminates the risk of abnormal noise in low temperature environments and effectively improves the vehicle's NVH experience; in addition, the chassis adopts a lightweight design , the swing arm is designed with a high-strength steel structure, and the steering knuckle is designed with an aluminum alloy to reduce the unsprung mass and improve comfort and control. The rear suspension adopts E type multi-link independent suspension, which is 100% flexibly connected to the body. The front and rear suspensions are crucially connected to the body at 12 All points use flexible connections, and the proportion of soft connections is as high as 86%, which is improving NVH span> performance, it also improves the experience and comfort of the vehicle occupants; the measured ride vibration vibration RMS value is 12% better than that of the same class, and the maximum lateral acceleration Reaching 0.85g, the overall road noise is better than the benchmark in the same class, bringing a comfortable, smooth, and dynamic driving experience.
As the first new energy dual-power SUV in the Wuling Starlight family, Wuling Starlight S won the title of "2024 China's Top Ten Chassis" in one fell swoop. It will be officially launched on 8 on 28, so stay tuned!
