This time, the professor got a performance version of M5 2022 four-wheel drive and gave everyone a comprehensive experience.
In order to present the performance of Wen Jie more objectively and truly, the professor chose the pure electric SUV-Weilai ES6 and Li ONE, who also used the extended-range hybrid, and compared it with Wen Jie to see how Wen Jie performed as a latecomer.
This comparative professor will come straight to the point, focusing on the power system, power experience and intelligent performance that consumers are most concerned about.
Let's start with the power system and chassis structure. M5 adopts extended range mixing scheme. Four-cylinder turbocharged engine with extended range of 1.5T, ultra-high compression ratio of 15: 1. Moreover, this engine, as a range extender, adopts an integrated EGR system and has done a lot of "slimming", eliminating the mechanical water pump, mechanical air conditioning compressor and other burdens. Coupled with the ultra-high compression ratio, its thermal efficiency is 465,438+0% and the maximum power generation efficiency is 3.2 kW h/L.
The four-wheel drive performance version is equipped with front and rear dual motors. The front motor is AC/asynchronous, with maximum power 165kW and peak torque of 420N·m, and the rear motor is permanent magnet/synchronous, with maximum power 150kW and peak torque of 300 N m. The comprehensive power of the system reaches 3 15kW, with total torque of 720 N m.
Weilai ES6 has two options in terms of power. The maximum power of the front and rear motors on the two sports versions is 160kW, and the total power is 320kW. The official 100-kilometer acceleration score is 5.6s；; Other versions are equipped with a rear axle motor with a maximum power of 240 kW. The total power of the system is 400kW, the total torque is 725n·m, and the acceleration time of 0- 100km/h is 4.7s s..
Li's power "formula" is the simplest, and the whole system is a power. The range extender is a 1.2T three-cylinder turbocharged engine from Dong 'an, with the maximum power of 96kW and the corresponding power generation efficiency of 2.76kWh/L, which is lower than that of a 1.5T four-cylinder engine from Wu Jie M5. In terms of motors, Li ONE also adopts the layout of front and rear dual motors, with a total power of 245kW and a total torque of 455n·m, and the acceleration of 0- 100 km/h is 6.5s s. ..
As for the suspension, both Weilai ES6 and Weilai ES6 adopt the combination of front double wishbone and rear multi-link, while Li one is the former McPherson and rear multi-link. From the suspension form, Wu Jie M5 and Weilai ES6 have higher specifications.
In addition, in terms of materials, Wu Jie M5 and Weilai ES6 are "stacked". No matter the front suspension or the rear suspension, the upper control arm, the lower control arm, the subframe and the steering knuckle of the two kinds of automobile suspensions are all made of aluminum. The advantage of this kind of stacking is naturally that it also brings lighter unsprung weight after meeting the strength and reliability.
As far as power reserve is concerned, the acceleration level of Wu Jie M5 performance version is better than that of sports version Weilai ES6, which is basically at the same level as ES6 performance version. Moreover, there is a flagship version with stronger acceleration ability, and the acceleration ability of both cars is obviously better than that of Li ONE. In terms of chassis suspension, Wu Jie M5 and Weilai ES6 have high specifications and are among the best in their respective market segments. However, the specific performance depends on the following dynamic comparison. After all, suspension is not only a hardware problem, but also a "tuning" problem.
In addition, it should not be overlooked that both Li ONE and Li One have adopted extended-range hybrid, and they can refuel in addition to pure electric vehicles, so there is no "endurance anxiety". Even Weilai said that "charging is more convenient than refueling", and the endurance performance and energy supplement experience of extended-range hybrid are better than pure electric vehicles.
And Li Yi are both extended-range hybrid vehicles. Although they can refuel, the engine will not directly participate in the output, and the motor will be responsible for driving. Therefore, in terms of power output characteristics, these three cars can be said to be consistent, with fast dynamic response and no transmission system such as gearbox, and the ride comfort of the three cars is impeccable.
Open the custom driving mode of M5, which has four power output modes: soft, standard, strong and ejection. Want to experience the most surging output, naturally choose ejection mode.
Step on the accelerator and brake at the same time, and then bounce off the brake pedal. The direct high torque of the motor is generated instantaneously. Thanks to the precise torque control of electric four-wheel drive, the four P-zero tires equipped by the original factory did not slip and the vehicle popped up instantly.
Therefore, we have no doubt about the acceleration ability and power reserve of M5, which is completely overflowing for daily road conditions. However, I would like to remind everyone here that in order to maximize the output power, the power of the power battery pack should not be in a low state, otherwise the output will be greatly reduced, which is the same as that of Li one, and it is also a mixed program.
Professor Wen Jie's M5 power reserve can be praised completely, but there is also a defect that needs to be pointed out, that is, when the range extender works and the vehicle speed is low, holding the steering wheel with both hands will feel weak vibration, which reduces its texture.
