Recently, a small electric detective found in the latest batch of "road motor vehicle manufacturers and products" of the Ministry of industry and information technology that SAIC Rongwei is about to launch a new NEDC with a endurance of 505km. The new car is a rear drive model, and the rear axle is equipped with two permanent magnet synchronous motors, and the power parameters are consistent with the current rear drive model. The size of the new car is basically the same as that of the current model, with the length, width and height of 4678 / 1919 / 1616mm, and the height of the new car is 2mm lower than that of the current model; the electric detective guessed that the wheelbase of the new car might also be 2800mm. In terms of power, the maximum power of left rear motor is 85KW, and the maximum torque is 255n · m; the maximum power of right rear motor is 52kw, and the maximum torque is 155n · M. In view of the constant motor parameters, the total power of the system should be the same as that of the current model, which is 137kw and 410n · m respectively. The biggest change of the new car should be the aspect. According to the Ministry of industry and information technology, the battery energy density of the new marvel X has reached 180.1wh/kg, and the NEDC has a endurance of 505km. Compared with the 403km of the current rear drive model, it has increased by 102km. In addition, the curb weight of the new car is 1840kg, while the current rear drive model is 1759kg. Part of the increased weight of the new and old models is undoubtedly the increase of the electric capacity, and the other part may be the weight of the liquid cooling temperature control system.
