The 19th session has already begun. At this auto show, wey brand brings two PHEV models, wey vv7 PHEV and wey vv7 GT PHEV, which are the other two models after the first appearance of plug-in hybrid technology. (site of wey press conference) at the same time, a year ago, the appearance of wey P8 marked that wey, a sub brand of great wall, officially entered the field of PHEV. The wey vv7 PHEV and wey vv7 GT PHEV, which appear on the market in Guangzhou auto show, are also the "decentralization" of wey brand plug-in hybrid technology. The principle of P0 + P4 architecture (wey brand pi4 platform) has been deeply analyzed in "graphic hybrid" (full name here, with hyperlink). In short, it is composed of a BSG (integrated motor for starting and generating) located at the belt end of the engine and a drive motor located at the rear wheelbase. (P4 architecture diagram) in addition, there is no physical connection between the front and rear axles for the four-wheel drive function realized by P4 architecture, so theoretically, the front and rear axles have faster power distribution speed and higher efficiency. In the hybrid mode, the output of the whole power assembly is equal to the engine + motor, and the power performance improvement is very significant. (wey vv7 PHEV / vv7 GT PHEV) wey vv7 / GT PHEV is equipped with 2.0T, the maximum power is 167kw, the maximum torque is 387n · m, and it is matched with 7-speed double clutch gearbox. The maximum power of the rear axle motor is 85KW, and the peak torque is 195n · M. Although the manufacturer has not published the comprehensive maximum output of the whole system, it can be simply understood as the sum of the two in terms of power architecture. The acceleration time of 0-100km / h is 5.9s. In addition to the power performance, as the name implies, P4 motor matches two gear deceleration, which can theoretically improve the acceleration performance and the electric drive efficiency at high speed cruise. At present, the main new energy vehicles on the market use fixed gear ratio single speed reducer, and the speed ratio is generally between 8-10. The electric drive system with two speed reducers means that higher cruising speed can be achieved in pure electric mode, and the problem of high power consumption and low efficiency can be solved to a certain extent when driving at high speed in pure electric mode. Both PHEV models are based on the fuel version, and the vehicle design is basically the same as the fuel version. The front face is still the family "leopard bionics" element of wey, with geometric array air intake grille, the visual impact is still very shocking, which fully meets the current young people's pursuit of sports style. (wey vv7 PHEV) in addition to adding PHEV logo to the rear part, it is still consistent with the fuel version. In particular, the exposed two-sided exhaust pipes with four outlets at the rear of the car are still very bluffing. In particular, the 5.9s acceleration time of the hybrid makes the four exhaust vehicles have corresponding strength. (wey vv7 GT PHEV) wey vv7 GT made its debut as early as 2019 at Frankfurt Motor Show. Based on the vv7 model, the sliding back modeling design was added and positioned at the car running crossover suv. PHEV version also keeps the design of the fuel version. There is no difference except for the PHEV logo added at the rear of the car. The interior parts of the two vehicles are basically the same as the fuel version, but the corresponding driving mode selection is added based on the PHEV model. Also at Guangzhou auto show, wey brand also brought new wey-x concept car. The concept car is based on a pure electric exclusive expandable platform. According to the manufacturer, (wey-x concept car) in addition, the wey-x concept car will also have a layout in the future of automatic driving technology. According to the manufacturer, the concept car will be directly equipped with L5 level automatic driving function in the future. In addition to the appearance of the new concept car, the wey brand also said on the spot: as the first wey brand model to be launched in 2017, the vv7 also achieved a monthly sales performance of 10000 at the beginning of its launch. But the good times are not long. With the passage of time and the fermentation of the terminal market, the sales volume of wey vv7 shows a continuous downward trend. Therefore, the wey brand needs not only a product that can help sales, but also a model that can help the wey brand make a voice in the new energy market.
