At the beginning of January this year, BYD's efforts to build the Yangwang U8 were officially unveiled, but there is still a lot of information that has not yet been revealed, such as interior design, power system, assisted driving capabilities, etc.
On February 6, Li Xiang, CEO of Ideal Auto, asked online: Looking up to the power structure of the U8 is a parallel PHEV? Or a tandem REV? Can an expert in power systems interpret it?
The so-called parallel PHEV is plug-in hybrid, and series REV is extended range hybrid, Li Xiang asked this question, maybe he really wanted to find out, maybe to prove the correctness and precursor of the ideal choice of range extension route, but regardless of the purpose, his problem did attract widespread attention.
In the comment area, many netizens also started a discussion, and some car bloggers revealed that the U8 adopts a four-motor extended-range hybrid system.
Some netizens added that it seems that because U8 is a hard off-road vehicle with a girder, the front two motors are staggered emissions, if it is direct drive, the structure will be very complicated, and it is really unnecessary, so the range extension has become the optimal solution.
In the comment area, many ideal fans said that even BYD uses extended-range hybrids, and those who say that this technology is "taking off your pants and farting", probably their faces are swollen; But some netizens said that the highlight of looking up to U8 is not in the range extension or mixing, but in the "Easy Sifang" technology platform, Li Xiang This kind of question is a smoke bomb, making people turn their attention to the discussion of range extension or mixing.
It is understood that the Yi Sifang technology platform of looking up to U8 has a four-wheel side motor, which can control the torque of each wheel separately, compared with the traditional mechanical full-time four-wheel drive system, the electronically controlled four-wheel drive system responds 100 times faster, and the adjustment range reaches 20 times, so that it can complete a variety of driving states, including turning around in place.
In addition, the car also has a variety of "black technologies" such as 120km/h flat tire stability control, straying into deep water and floating to get out of trouble.
