Although they are all in the high-growth new energy vehicle market, there is no doubt that electric hybrid technology is definitely more favored by the market than pure electric vehicles. In the electric hybrid technology, there are two technical routes, namely plug-in hybrid and extended range technology, compared with traditional fuel vehicles, these two power technologies are undoubtedly more fuel-efficient, but they also have their own shortcomings. The former is slightly less smooth to drive, especially at slow speeds, while the latter is less dynamic, especially at high speeds.
However, now, under the technical research of large central enterprises, a power technology that intelligently switches between plug-in hybrid and extended range according to different usage scenarios has been born, which further solves the problem of these two electric hybrid models and breaks through the bottleneck of application.
It is the Mach electric hybrid PHREV developed by Dongfeng Motor.
But just talking about technology without experience, how can we feel the charm of Mach electric hybrid PHREV? A few days ago, Cheshi Classic was invited to participate in the test drive experience of Dongfeng Fengshen L7 in Yunnan. This car is the first model equipped with Mach electric hybrid PHREV under Dongfeng's own subsidiary, according to Dongfeng Fengshen insiders, this is a new beginning after the Fengshen brand takes power technology as a watershed.
Since it is a watershed in terms of power technology, the driving experience of the Dongfeng Fengshen L7 is crucial. In urban areas, the first start is quiet, highlighting the advantages of the all-electric mode, but the acceleration is quite linear, not as aggressive as many previous all-electric models, and smoother than plug-in hybrids.
However, in hybrid mode, the sound of the range extender intervention is barely noticeable, and I can only say that the engine compartment sound insulation of this car is really good. At high speeds, the engine is sometimes in direct-drive mode, and the acceleration and deceleration are always very smooth and smooth, which is better than the general electric drive model.
Of course, the coach in the same car said that if you choose the sports mode, whether it is a normal city road or a high speed, you will have a more aggressive experience.
And it also depends on the engine on the Dongfeng Fengshen L7. It is understood that this engine is specially configured by Dongfeng for PHREV, the 1.5T engine has a maximum power of 265kW, a maximum torque of 615N·m, and the engine thermal efficiency of the engine has reached the absolute leading 45.18% in the industry.
In addition to this engine, the most important thing about this PHREV hybrid system is that it adopts the industry's first fusion configuration, which integrates power shunt ECVT and 4-speed DHT series and parallel structure, with 7 major energy management modes and 26 subdivision working modes, with a system efficiency of 93% and a high-efficiency zone utilization rate of 95%.
Supporting such a complex working mode is the strongest "brain", i-Control intelligent electronic control system, which can automatically match the optimal driving mode for users according to real-time road conditions and users' driving habits, pure electric, extended range, plug-in, without manual switching, and automatically improve the use of energy consumption and performance in actual scenarios.
In short, after a relatively long period of driving, the author feels that this car can completely control a series of adjustments such as throttle, braking, and corner control through the understanding of the owner's driving habits and the recognition of the scene, so it can achieve zero hundred acceleration 6s level, NEDC feed fuel consumption of 3.8L/100km, and WLTC comprehensive fuel consumption of 0.56L/100km.
It is precisely because of such technical support that although Dongfeng Fengshen L7 is only equipped with a 30.2kW·h lithium iron phosphate battery, it has a 205km pure electric range and a 1500km comprehensive range (due to the time arrangement, the author did not test the battery life, and will experience it again in the next long test), and the power from 30% to 80% only takes 26 minutes, and the owner does not need to worry about mileage and energy replenishment.
Power technology is of course the biggest selling point of Dongfeng Fengshen L7, but the rest of the car is also worth mentioning, after all, it is a new beginning of Fengshen brand new energy, and the appearance of the new car has also been completely redesigned.
It is understood that the design of the new car is inspired by the "light-year journey", with the "physical change of light" to carve the body lines, with the concept of "long-term companionship" to bring warmth to the design. The front face uses edges and corners and LED light groups to outline a pair of dynamic wings, "Little Tiger Teeth" type smart lights, digital light wing curved LED welcome lights, and photon ripples through the front light group, and the aesthetics of science and technology are vividly displayed.
The side of the body is a hidden door handle design, the body attitude is low and smooth, and the lower drag coefficient can also obtain better energy consumption.
In terms of dimensions, the new car has a length, width and height of 4685mm/1905mm/1625 mm, and a wheelbase of 2775mm, which makes this compact SUV have better space performance.
What is reflected in the car is the "smart" part of this intelligent hybrid SUV. Dongfeng Fengshen L7 is equipped with WindLink OS 3.0 intelligent cockpit, the whole system is equipped with Qualcomm 8155 chip + 14.6-inch LCD screen + 10.25-inch LCD instrument screen, human-computer interaction can achieve 8 continuous instructions in 10 seconds, and can also recognize Mandarin, Cantonese and Sichuan.
In addition, the new car also supports L2 autonomous driving assistance functions and FOTA upgrade functions, making driving easier, more convenient and more common for owners.
Of course, although the test drive of Dongfeng Fengshen L7 is still an engineering version, the orange and black double-spell interior is still very attractive (I wonder if there will be more color options after the production version), plus the pocket design, floating island central control design, integrated sports seats, these are all young elements in line with the current trend.
Write at the end:
PHREV, this plug-in, extended-range, and pure electric power technology, not only allows Dongfeng's independent sector to take the lead in the competition of new energy, but also allows its product - Dongfeng Fengshen L7 to occupy the technical commanding heights of intelligent hybrid SUV, coupled with the integration of new energy and innovative intelligent cockpit and intelligent driving configuration, I believe that this new car can start the first shot of the brand's new start for Fengshen, and now it is only waiting for its pricing.
