Ultra-low fuel consumption overwhelmed the opponent, and Roewe D7 DMH won the double champion of the mixed challenge.
Recently, the results of the 2023 hybrid vehicle extreme challenge competition were announced. The Roewe D7 DMH won the first place in the medium and large car group with its excellent comprehensive performance over BYD Han DM-i and Guangqi Honda Accord PHEV. At the same time, in the fuel consumption test of power loss, Roewe D7 DMH won the championship of the whole model with the ultra-low fuel consumption of 4.61L/100km.
The 2023 Hybrid Vehicle Extreme Challenge is jointly sponsored by China Automotive Information Technology (Tianjin) Co., Ltd. and China Automotive Research Center (Kunming) Co., Ltd., and it is the first professional competition for hybrid vehicles in China. The participating models include several popular hybrid vehicles in the market, and the test items include pure battery life, fuel consumption due to power loss, comprehensive energy consumption, extreme energy consumption, NVH, power and so on, which can comprehensively evaluate the comprehensive strength of hybrid vehicles.
Super hybrid
Ultra-low fuel consumption and long battery life
The long-distance test site of this challenge is set in Yunnan-Guizhou Plateau, where the terrain changes are relatively complex and the altitude is challenging, 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 long as 1400km, which is enough for users to travel without worry and run further.
In addition to the cruising range is far ahead, Roewe D7 DMH’s performance in power and fuel consumption is also remarkable. Roewe D7 DMH adopts the industry’s first "five-in-one" PICU power domain controller with engine, gearbox, hybrid mode, thermal management and air conditioning management. One of its advantages lies in its extremely fast dynamic response, which only takes 0.26 seconds. In the 0-100km/h acceleration measurement, the Roewe D7 DMH 0-100km/h acceleration only takes 8.3 seconds, and the power acquisition is very easy.
According to the actual measurement, the Roewe D7 DMH’s power loss and fuel consumption are only 4.61L/100km, which is the lowest among all the participating cars. 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, Roewe D7 DMH adopts dual motors in parallel, providing five driving modes. Users can choose their own driving modes and run in an optimal state under various working conditions. The power should be strong at times, and the fuel consumption should be reduced at times, thus improving the overall efficiency and reducing the vehicle cost.
Yunsu intelligent cockpit
Silky, smooth, broad, luxurious 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, which matches the world-class chassis suppliers such as SKF, Weibak and GF, and the 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 various road conditions, Roewe D7 DMH greatly reduced the front and rear force from the road surface, and at the same time, with the blessing of comfortable braking function (CST), the brakes did 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 the super-long wheelbase of 2810mm, Roewe 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-based somatosensory seat with high-grade suede is widely used, the backrest is made of 9 layers of selected materials, and the soft foam with the first thickness of the same class is standard, and the U-shaped embracing design is adopted 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, collaborative mute technology actively suppresses noise from noise sources, and quietness adds more comfort to comfortable space.
Roewe D7 DMH is also equipped with a brand-new Zebra Intelligent Driving Machine System, which not only supports "one word with many meanings", 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, at the same time, it can meet the multiple needs of users and create 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. With the advantages of long battery life, ultra-low fuel consumption, excellent driving control and comfortable driving experience, the Roewe D7 DMH won the first prize in the extreme challenge of hybrid cars, demonstrating the quality and charm of super hybrid cloud car, further consolidating Roewe’s position as a pioneer in the field of hybrid technology.
