Yiche original 2000 km, this number is the ceiling of the recent breakthrough of China's hybrid cars.
Not long ago, several major media, including Yiche, launched an extreme endurance challenge from Kunming, Yunnan to Wuhan, Hubei for the Dongfeng Fengshen L7.
Under full fuel and full power, Dongfeng Fengshen L7 has been measured to a comprehensive range of 2000km, compared with the official calibration of 1500km comprehensive range, it has actually achieved a reverse virtual standard, and the pure electric range record has exceeded 320km, and the range achievement rate is up to 156%.
Such an achievement is placed in such a volume of the hybrid market, which can be described as amazing, how is the Dongfeng Fengshen L7 completed? What technical code is hidden in it? Then look down, you will know.
The technical password of the reverse false standard
In the current hybrid power technology route, the pioneers generally adopt two schemes:
The first is the power diversion represented by Toyota, the advantage is that the urban road section is fuel-efficient, but when it comes to high-speed driving, fuel consumption will soar; the second is the current mainstream choice of series-parallel mode, which is mainly electric drive at low speed, and the driving pleasure is comparable to that of the tram, but the disadvantage is that the utilization rate of the engine in the efficient range is low.
Is there a technology that can avoid the shortcomings and take into account the advantages of both? Yes, this is the technical code of Dongfeng Fengshen L7 - Mach electric hybrid PHREV.
To put it simply, Mach electric hybrid PHREV is a model that integrates four-speed DHT series-parallel + power shunt, which can realize diversified use scenarios such as extended range, plug-in hybrid, and pure electric, and Dongfeng Fengshen L7 is the first model of Mach electric hybrid PHREV technology.
The entire powertrain integrates 7 hybrid energy management modes:
Including parking power generation, pure electric drive, energy recovery, series drive, multi-gear direct drive, multi-gear parallel, as well as a unique dual-mode power shunt mode, the power shunt is used to switch between different gears, making the gear shift smoother and the power output more stable.
Of course, it is not enough to look at the structural theory alone, the key is to rely on the power of the engine, electronic control, battery and other key components, and how to match and integrate, which can support the comprehensive endurance of 2000km.
First of all, the Dongfeng Fengshen L7 is equipped with a 1.5T hybrid engine, with a comprehensive power of up to 265kW and a torque of up to 615N·m under the combination of the motor.
The thermal efficiency of the engine is a key indicator of hybrid technology. In order to maximize the power efficiency, Dongfeng Fengshen improves thermal efficiency by applying variable section turbocharging technology and breaking through the pulse bandwidth.
Compared with the traditional technology, the variable section turbocharging technology has increased the pressure end efficiency and vortex end efficiency of the turbocharger by 7%, which is equivalent to using only one turbocharger to achieve the effect of multiple turbochargers.
Under various innovative technologies, the thermal efficiency of this engine has reached 45.18%, which is higher than that of BYD, a friend next door. Moreover, it also has higher technical reserves, which will exceed 47% in the near future, which will once again refresh the industry level.
In addition, this system is also equipped with i-Control, which can automatically implement the optimal control strategy according to each user's driving habits and travel road condition prediction, and can automatically improve energy consumption performance without manually switching between different modes of EV, REV, and PHEV.
Finally, let's take a look at the battery, in addition to the entry-level version, other versions are equipped with 30.3kWh energy density Mach batteries as standard, and the quality has reached the "military vehicle level".
This battery also uses AI self-healing algorithm, which makes the battery cycle life reach more than 2,000 times, making users feel more at ease.
The whole power structure is very ingenious and precise, giving Dongfeng Fengshen L7 a fuel consumption performance and endurance that surpasses its predecessors. According to the official data, the fuel consumption of Dongfeng Fengshen L is only 3.8 liters per 100 kilometers, which is much lower than that of competing products in the same level, indicating that it not only runs far, but also very economical.
If you want to save more, users can also use it as a pure electric vehicle, with a pure electric range of up to 205 kilometers, and the daily urban commute only needs to be charged once or twice a week, and the fast charge is 30%~80%, and the duration is only 26 minutes, which is equivalent to a meal to restore power.
Dongfeng Fengshen L7 has achieved a long endurance of 2000km, 3.8L/100km feed fuel consumption, coupled with smooth and easy driving, from these characteristics, Fengshen L7 does have two brushes, obviously has the potential of the rookie volume king.
You must know that in the past, including BYD, Geely, Chery and other car companies have entered the plug-in hybrid technology, but it can reach a comprehensive range of more than 1000 kilometers is already at the head level, and now Dongfeng Fengshen L7 has broken the ceiling through technological breakthroughs, and achieved a reverse false standard, raising this number to 2000km, which is difficult for friends to surpass later.
N reasons to buy Dongfeng Fengshen L7
In addition to the core power technology password, Dongfeng Fengshen L7 also has highlights in terms of appearance, comfort, and configuration.
Dongfeng Fengshen L7 "Light Year Journey" design inspiration is very fashionable, the front face of the flying wing + the tail of the fighter to create a fashionable texture is very in line with today's mainstream trend, even the popular smart lights, rhythm atmosphere lights and other trend elements have not fallen, I have to say that the aesthetic level of domestic cars is now NEXT LEVEL.
The body size is 4670mm long, 1900mm wide, 1625mm high, and the wheelbase is 2775mm, and the overall size is above the same level.
The intelligent cockpit is also a major selling point of Dongfeng FengshenL7, the whole system is equipped with Qualcomm 8155 chip + 14.6-inch LCD screen, which can achieve 100% voice interaction in all scenes, and the response speed reaches the millisecond level, and 8 consecutive instructions can be completed in 10 seconds.
In addition, the level of autonomous driving assistance has reached Level 2, and there are all kinds of equipment such as lane merge assist, lane keeping assist system, road traffic sign recognition, and automatic lane change assistance (depending on the model version).
The 13-speaker 360-degree surround sound with independent amplifier makes people feel like they are in a small music theater, and the front and rear rows are equipped with segmented ergonomic sports seats, so you can sit for a long time without getting tired, and feel comfortable and self-reliant.
In order to further improve the dynamic quality, Dongfeng Fengshen L7 also introduces a full-scene adaptive noise control system, even under extreme conditions of rapid acceleration of feeding, the noise increment into the car can be controlled within 3 decibels, as a comparison, other competing products of the same level should reach about 8 decibels.
Dongfeng Fengshen L7 also introduces a neural network algorithm model, which can dynamically control acceleration and deceleration in real time, control the transient acceleration slope within 0.9g/s, and accurately control the acceleration time, thereby alleviating the pain point of passengers getting motion sickness when speeding up.
There is only one reason why a user refuses to buy a car, and it takes many reasons to really like a car and dig out their wallet for it. Obviously, Dongfeng Fengshen L7 belongs to the latter, low fuel consumption, long battery life, high configuration, Dongfeng "big factory" guarantee, these reasons are enough to make people plant.
Having said all this, in fact, the most important thing is that in addition to the price, it is still the price.
At the Guangzhou Auto Show that opened on April 25, Dongfeng Fengshen L7 officially opened pre-sale, with a price range of 128,900-156,900 yuan, and a low configuration of less than 130,000 yuan, which is a plug-in hybrid SUV with a pure electric range of more than 200km, which is rare in the same class, which shows how volatile the price is and how cost-effective.
summary
For Chinese consumers, who can buy a plug-in hybrid SUV with all aspects for more than 100,000 yuan, the Dongfeng Fengshen L7 is indeed a good choice. Mach electric hybrid PHREV is the technical password of Dongfeng Fengshen L7, and cost-effective and high quality are its background colors, as if it has the absolute potential of a 150,000-yuan SUV dark horse.
