On April 6, the well-known car blogger "Brother Tiger" carried out a pure electric endurance challenge in Yunnan - driving the Dongfeng Fengshen L7, a "long-range intelligent hybrid SUV" with a pure electric range of 205km, from Kunming Airport to Maitreya, and the whole process was broadcast live for two and a half hours, just to test the most real pure electric range of the vehicle. In the case of almost full load, full air conditioning, and high-speed driving of 90-100km/h most of the time, Fengshen L7 has 23km of mileage left in the battery after running the official calibration of 205km, and the cumulative range can reach 228km.
It can use electricity without oil, and urban cars are easy to use
Different from the endurance test of "traveling as light as possible in order to achieve good results", the pure electric test of Fengshen L7 in this event is to restore the user's real car use scene. The vehicle is not only loaded with a variety of large photography and video equipment, but also invited two "heavyweight" guests to accompany them, among them, Dr. Chen Gen of the Mach Power R&D team revealed a lot of Dongfeng Fengshen L7 "power-saving secrets" for users during the test.
From Kunming Airport to Maitreya, the test drive includes urban paved roads, urban expressways, high-speeds, ultra-long tunnels, national highways, etc., covering most of the user's car scenarios. As we all know, high-speed roads are more power-intensive than urban road conditions, so even if only according to the official 205km pure electric range, in most cases, the pure electric mileage of Fengshen L7 can basically support urban car owners for about a week of commuting.
The cruising range of the "reverse false standard" depends on the industry-leading Mach power battery. "While the highest plug-in hybrid SUV in the same class is generally at the 18 kWh power level, Fengshen L7 uses a 30.2 kWh Mach power battery, which achieves an ultra-long pure electric range with nearly twice the power. Chen Gen said.
Most of the time, users who buy a hybrid want the economy of an all-electric model, but they don't want to have range anxiety. Therefore, the "electricity-based, oil-emergency" model is what they really need. The Fengshen L7 is far ahead of the official 205km pure electric range of the same level, which can be used as a pure electric car in daily life, and then refueled for long distances to fully meet the needs of users.
Powerful, smooth, and non-motion sickness The Mach hybrid PHREV has a killer feature
"Just like us at work, the hybrid engine must work in the most comfortable place for high efficiency and fuel saving. Chen Gen explained in simple terms why Fengshen L7 is "very sensible": Mach electric hybrid PHREV has integrated and innovated the two major hybrid technology schools of power shunt and series-parallel connection, and realized the integration of a variety of new energy drive modes and advantages with a simple structure.
Therefore, when it is necessary to speed up, this "smart and sensible" system will switch to the strongest parallel drive mode, at this time, the power output of the engine and the motor is very fast, but because the system controls the engine efficiency zone more accurately, the engine can play the greatest energy efficiency in the best speed range, that is, the "most comfortable place", so that the power, smoothness, and energy consumption can achieve the best balance.
Because of this, it is usually impossible to "eat less" and "run well" on the body, but the Fengshen L7, which has a fuel consumption of 3.8L per 100 kilometers, has a good power experience. It has a maximum power of 265kW and a peak torque of 615Nm, and also has a 6-second 000 acceleration level, which is rare in its class.
"The acceleration is really fast, and the acceleration is linear. "The strong and smooth that Brother Tiger praised in the live broadcast is also the power of Dongfeng Fengshen L7's first technology - Mach electric hybrid PHREV.
"It's like a team, if you want to do well, you need not only good players, but also good coaches, good assistant coaches, and good tactics. Brother Tiger used an easy-to-understand metaphor to let everyone intuitively understand the "strongest brain" of Mach electric hybrid PHREV - the industry-leading i-Control intelligent electronic control system, its AI predictive energy management system, according to real-time road conditions and the user's driving habits, with self-learning function, can automatically match the optimal driving mode for the user, so that everyone can drive Fengshen L7 to achieve or even exceed the pure electric range record of 228km in this test.
"Many users don't like trams because they are prone to motion sickness, how can this be solved?" On the test road, Brother Hu sent a "torture" to Chen Gan. In fact, motion sickness caused by fast acceleration and rapid acceleration of the tram has plagued many users. In this regard, Dongfeng Fengshen L7 innovatively uses power shunt for gear shifting, so that the power output of the gear shift process is stable, and at the same time, the engine speed can be controlled more smoothly, so as to achieve CVT-like silky shift and ultimate energy saving, and achieve real "linear acceleration".
It is understood that in the future, more professional media will participate in the 205km pure electric range challenge of Dongfeng Fengshen L7.
