Roewe D7 DMH Hybrid Challenge won the double champion!

On October 7th, the results of the 2023 hybrid vehicle extreme challenge competition were announced. The Roewe D7 DMH, a "super hybrid cloud car", won the first place in the medium-sized and large-sized car group with its excellent comprehensive performance. At the same time, in the fuel consumption test, Roewe D7 DMH won the championship of the whole vehicle with the ultra-low fuel consumption of 4.61L/100km, which proved with strength that "the strongest is in China, and the strongest in China is in Roewe".

Co-sponsored by China Automotive Information Technology (Tianjin) Co., Ltd. and China Automotive Research Center (Kunming) Co., Ltd., this challenge is the first professional competition for hybrid vehicles in China, covering several popular hybrid vehicles in the market. The test items include pure battery life, fuel consumption due to power loss, comprehensive energy consumption, extreme energy consumption, NVH, power performance, etc., which can comprehensively evaluate the comprehensive strength of hybrid vehicles.

Relying on technology brands, a forward-looking new energy source of SAIC, Roewe launched the first plug-in hybrid car "Roewe e550" in China in 2013. The first generation of EDU hybrid technology independently developed by SAIC won the second prize of the National Science and Technology Progress Award in 2017, which was not only the only automobile project among the award-winning projects in that year, but also the first time that new energy technology won the national science and technology award. After ten years of sharpening, after continuous technical investment and innovation, Roewe D7 DMH equipped with a new generation of DMH dual-motor hybrid technology will be launched this year, providing users with more stable and efficient hybrid new choices.

Super hybrid: ultra-low fuel consumption and long battery life

The long-distance test of this challenge is set in the Yunnan-Guizhou Plateau with relatively complex terrain changes and certain challenges in altitude, which can simulate the travel scene of consumers more realistically. Thanks to the technical advantages of the dedicated high-efficiency long-life battery, Roewe D7 DMH won the first place in the actual battery life measurement with a battery life of 142km, which was significantly better than that of the same group. The comprehensive cruising range is as high as 1400KM, which is enough for users to travel without worry and run further.

In addition to the long battery life, Roewe D7 DMH’s performance in power and fuel consumption is also remarkable. D7 DMH adopts the industry’s first PICU power domain controller with five-in-one engine, gearbox, hybrid mode, thermal management and air conditioning management. One of its advantages lies in its extremely fast dynamic response, which only takes 0.26S s.. In the 100-kilometer acceleration measurement, D7 DMH only takes 8.3S seconds to accelerate at zero hundred kilometers, and the power is very easy to obtain.

According to the actual measurement, the fuel consumption of Roewe D7 DMH is only 4.61L per 100 kilometers, which is the lowest among all the participating models. The ultra-low fuel consumption is attributed to the thermal efficiency of the 1.5L hybrid engine exceeding 43% and the ultra-low loss brought by 18 world-leading low-friction technologies. Under the condition of ensuring sufficient power output, the fuel consumption can still be maintained at a relatively low level. In addition, D7 DMH adopts dual motors in series, providing five driving modes. Users can choose the driving mode independently, and run in an optimal state under various working conditions. The power is strong and the fuel consumption is time-saving, which improves the overall efficiency and reduces the vehicle cost.

Yunsu intelligent cockpit: silky smooth, spacious and quiet.

The challenge test track runs across the Yunnan-Guizhou Plateau from east to west, with the characteristics of steep slope, sharp bend and slippery road, which tests the dynamic driving and control performance of vehicles. Roewe D7 DMH adopts multi-link rear suspension, and matches with international first-class chassis suppliers such as SKF, Weibak and GF, as well as the systematic and ingenious adjustment of the chassis of SAIC Innovation and Research Institute, thus ensuring excellent handling performance and precise and delicate steering. In the test, in the face of all kinds of road conditions, D7 DMH greatly reduces the front and rear force from the road surface, and at the same time, with the support of CST, the brakes do not nod. With the aluminum alloy wheel bracket, the isolation effect in the car is better and the overall dynamic comfort is better.

In terms of driving experience, Roewe D7 DMH’s carefully polished intelligent cockpit will bring users the comfort of staying in the cloud. With the longest body of its class of 4890mm and an ultra-long wheelbase of 2810mm, D7 DMH can realize flexible seat combinations, meet the needs of multiple scenes, and create a necessary happy space for mid-to high-end cars. The zero-gravity cloud somatosensory seat with high-grade suede is widely used, and the backrest is made of 9 layers of materials. It comes standard with soft foam with the first thickness of the same class, and adopts U-shaped embracing design to fit the waist curve of Chinese people, so that the waist and buttocks can be effectively wrapped and elastically supported. The length of the front and rear seat cushions has reached the leapfrog level, providing better support for the legs, sedentary and not tired, and the overall main "cloud feeling" general comfort experience. In addition, the collaborative mute technology actively suppresses noise from the noise source, and quietness adds more comfort to the comfortable space.

Roewe D7 DMH is also equipped with a brand-new Zebra Intelligent Driving Machine System, which not only supports multi-meaning in one word, but also allows users to express 10 intentions in one sentence. Moreover, cars and mobile phones can flow seamlessly, and information such as countdown to traffic lights and tidal lane can be displayed dynamically in real time, which is practical, convenient and worry-free, while meeting the multiple needs of users and creating rich driving pleasure.

Roewe D family was born to meet the whole scene consumption demand in the new energy technology era, and it is also a brand-new image of Roewe in the new energy technology era. As the first model of D family series, Roewe D7 is the epitome of SAIC’s profound knowledge and innovative ability of new energy technology. This time, the Roewe D7 DMH won the first prize in the extreme challenge of hybrid cars with the advantages of long battery life, ultra-low fuel consumption, excellent driving control and comfortable driving experience, showing the quality and charm of super hybrid cloud-feeling cars, and further consolidating Roewe’s position as a pioneer in the field of hybrid technology.
