At the same time, SAIC Maxus MAXUS EUNIQ 7’s leading architecture design further guarantees the safety of drivers and passengers. Taking the lead in realizing the world’s leading hydrogen system in the middle, combined with the advanced dual-loop redundant power and hydrogen shutdown design, EUNIQ 7 can meet the two major standards of China and the European Union for all-round collision safety protection. The hydrogen bottle in the collision experiment was intact and the system was leak-free, Guarding users’ travel safety in all directions.
In addition, the SAIC Maxus MAXUS EUNIQ 7 vehicle has also undergone rigorous endurance road tests and weather resistance tests, with a total mileage of 1 million kilometers, equivalent to 25 laps around the earth, ensuring reliable vehicle quality. Coupled with the lean production and strict quality control of the world’s first Chinese vehicle manufacturer “Lighthouse Factory”-SAIC Maxus Nanjing C2B Plant, it further guarantees the quality and performance of EUNIQ 7.
Ingenuity, EUNIQ 7 surging output excellent performance
In terms of power, SAIC MAXUS EUNIQ 7 is the first full-power direct-drive fuel cell vehicle in China. It uses 130kW fuel cell and 70Mpa hydrogen storage system, matching high-performance three-in-one electric drive bridge and domestic leading high-rate power battery. Create high-quality performance. The key performance indicators such as stack power, fuel economy, and service life have all reached the international first-class level.

The excellent performance of EUNIQ 7 also perfectly solves the problem of mileage anxiety. It only takes 3 minutes, which is the time of a cup of coffee, to fill the EUNIQ 7’s 6.4kg high-pressure hydrogen cylinder. Its NEDC cruising range can reach 605km, and its hydrogen consumption per 100km is 1.18kg, which is equivalent to only 0.4 yuan per kilometer. At the same time, EUNIQ 7 can achieve the world’s cutting-edge low-temperature start-up at -30°C, and adopts stack waste heat heating technology, with almost no mileage degradation in low-temperature climates.
