In the face of the reform of the new energy structure, Chinese consumers' awareness of new energy hybrid vehicles is increasing day by day, in order to promote the acceleration of China's SUV market into the hybrid era, haval brand with lemon hybrid DHT as the core technology route for product layout, to compete with joint venture brands.
With the listing of Haval Red Rabbit and Haval H6S two models equipped with lemon hybrid DHT technology, the Mythical Beast Lemon Hybrid DHT version will also be listed in the near future, and the future will gradually achieve full coverage of the main models equipped with lemon hybrid DHT technology.
A few days ago, auto-first test drove the first hybrid version of the Great Wall Haval model Red Rabbit DHT hybrid version, let's see if this car can have the "king" strength of the compact SUV market.
Lemon DHT hybrid technology PK "two fields"
From the perspective of hybrid technology, in the view of automotive Auto-First, there are four categories of hybrid systems on the market, namely 48V light hybrid, extender, plug-in hybrid and oil-electric hybrid system.
48V light hybrid system in short, is to add a set of 48V batteries on the basis of 12V batteries, to meet more on-board electrical power consumption, the traditional fuel engine changes are small, the brand to Mercedes-Benz, BMW as the representative.
The extender system is to convert the drive mode into an electric drive, the engine is responsible for converting kinetic energy into electrical energy, the advantage is that the low-speed electric drive saves fuel, and the fuel consumption will be high due to energy efficiency problems at high speed.
Plug-in hybrid (PHEV) is similar to oil-electric hybrid, which does not use an external power supply and relies on the engine to charge it, while plug-in hybrids require additional power supply to charge in order to meet the endurance of short-range 0 fuel consumption.
The more common oil-electric hybrid system is Toyota's THS and Honda's i-MMD hybrid system, both of which make the engine fuel efficient and the motor adjust to achieve low fuel consumption. The Great Wall Motor Lemon DHT hybrid system adds an original two-speed reducer to seek differences in technical solutions and achieve a wider range of road adaptation capabilities. By combining the high-efficiency hybrid engine and the dual-motor hybrid, it can be compared with the hybrid technology of the two fields, and further optimization in terms of NVH and smoothness.
Thanks to this, the Haval Red Rabbit DHT Hybrid Edition is equipped with a power combination of 1.5L + DHT codenamed 4G15H, which has a good performance. From the data point of view, its maximum power can reach 140kW, the comprehensive torque is 370N·m, the acceleration time of 0-60km is 3.9 seconds, the power performance is outstanding, and the response time is far beyond the conventional performance of the same level of 1.5L engines. According to the data, the fuel saving rate can reach 35 to 50% under urban conditions, its cruising range can exceed 1000km, and the comprehensive fuel consumption is 4.7L/100km.
Experience the pleasure of speed at all times
The Haval Chitu DHT Hybrid model consists of a 1.5-liter naturally aspirated engine, a 2-speed DHT hybrid transmission (interior GM and TM motors) and a 1.69kwh ternary lithium battery with a total power of 140kW and a combined torque of 370N.m.
In the test drive process, in the case of sufficient batteries, during the low-speed driving process, stepping on the accelerator pedal motor will quickly intervene in the work, the intervention time is relatively fast, making people feel that the response is fast, and the moment of starting, you can feel the obvious acceleration performance, and there is a feeling similar to driving a pure electric vehicle.
The vibration and noise control of the engine start moment is also very in place, in the parking process or waiting for the traffic light, the battery is sufficient, the engine will turn off, similar to the start-stop function, at this time you can feel that the vehicle has a very good quietness, but the moment of releasing the brake pedal, not only the power response is rapid, and can be timely feedback, so that people have a desire to experience the performance of the car.
After starting, if you want to speed up quickly, after stepping on the pedal deeply, the engine and motor will intervene at the same time, the power connection is relatively compact, and the linear power output will not have the slightest delay, which is an advantage that traditional fuel vehicles do not have.
DHT hybrid transmission adopts two-speed reducer setting, with the engine in low speed and high speed two working conditions of operation, when the need for strong power, can obviously feel the explosive force of the motor instantaneous transmission, to make up for the 1.5L engine in the low speed of the weak power of the short board, and then with the engine together to drive, bring a good sense of acceleration.
Haval Red Rabbit DHT hybrid version of the model uses a relatively smooth shift logic, D gear and R gear switching stroke is shorter, in the electronic gear, the tactile feedback effect of the switching process is not ideal, always let people have a feeling of switching unreal.
In the drive mode, the vehicle speed will adopt a series mode when the speed is 0~50km/h, the engine + GM generator provides power, and the TM drive motor drives the wheels separately; 50 ~ 65km/ h at the speed of the power direct drive mode, 65km / h above the use of economic direct drive mode, the engine through the DHT small speed ratio gear set directly drive the wheel, TM drive motor dynamically adjust the engine working point, to ensure the best working range of the engine. During acceleration, the engine and the motor output power at the same time.
Haval Red Rabbit DHT Hybrid Edition is also equipped with a kinetic energy recovery system, divided into mild, standard and strength three gears, in the actual driving process, the difference between the three kinetic energy recovery is not large, kinetic energy recovery will be enabled after the release of the accelerator pedal, through the dashboard power output renderings can also be real-time feedback, which is similar to electric vehicles.
In addition to the power performance of the Red Rabbit DHT Hybrid Edition, the test drive also experienced the L2 level driver assistance system, which has a 0-150Km/h full-speed ACC adaptive cruise capability, which can automatically take acceleration, deceleration, braking, etc. according to road conditions, which can be well adapted to complex urban roads.
After passing the short-distance test driving experience, it was found that after the new car was turned on the L2 level auxiliary driving function, the steering wheel steering could be adjusted in real time according to the road conditions, and during the entire driving assistance process, if the road conditions were good, there would be a good driving experience, but in the case of complex road conditions, there is still room for improvement in the recognition effect of this automatic driving assistance system.
As a 100,000-level home SUV, driving comfortable and fuel-saving is fundamental, the comprehensive fuel consumption of NEDC given by the Red Rabbit DHT Hybrid Edition is 4.7 liters, and after a short period of urban road conditions and high-speed road conditions alternate driving experience, the vehicle's fuel consumption meter is 5.2 liters, basically in line with expectations.
Create a youthful "explosive" potential
Haval Red Rabbit DHT Hybrid Edition and Fuel Edition model in the design of the basic no difference, the overall style is biased towards youthful, in the front surround, side skirt and rear bar are decorated with red trim strips, improve the sporty performance, more eye-catching. The design of the chrome-plated vertical grille improves the recognizability.
The sharp headlight group shape, with the circular fog lights on both sides and the vertical LED daytime driving, make the front face more visually impactful. The large area of chrome trim and red decoration undoubtedly increased the value.
In terms of body size, the length, width and height of the Red Rabbit DHT hybrid version are 4470/1898/1625mm, and the wheelbase size is 2700mm, which is consistent with traditional fuel vehicles. The "DHT" logo on the side of the body indicates its identity. The side of the car also features black door handles and decorative kits to enhance the youthful and sporty atmosphere.
The rearview mirror also has a side warning function, which can effectively avoid the visual blind spot on the side of the car during safe driving, and is very practical for young novice drivers.
The Red Rabbit DHT Hybrid Edition features 18-inch two-tone multi-spoke wheels with red brake calipers for a sporty feel, and the tires are matched by Kumho 225/55 R18-inch tires.
The rear of the body, the hollow spoiler and the red lower guard plate decoration strip make the tail shape add the characteristics of the performance car, and the through-type taillights also stretch the lateral vision of the tail, and the hidden exhaust design makes the whole more unified.
In order to cater to younger consumers, the interior of the vehicle is embellished with fluorescent green trim strips and stitching processes. With the suspension of the central control screen and the air conditioning outlet design through, the decorative board of piano paint, etc., the interior adds a sense of refinement.
The three-frame steering wheel style is relatively novel, using fluorescent color stitching process leather wrapping, delicate touch, multi-functional button layout is relatively clear, but during the experience, it was found that the degree of use of various functions requires a certain amount of time to be familiar.
The overall performance of the 7-inch LCD display instrument and the 12.3-inch central control screen is also excellent, especially the screen definition is very good, and the reaction speed is relatively smooth, but during the use of the vehicle, it is found that when the vehicle is hung into the reversing gear, the central control screen is switched from the main interface to the image interface, and the system will be slightly delayed.
The new seats are wrapped in a mix of imitation leather and fur materials, and the seat filling is relatively soft, and the comfort of the ride is not bad. The one-piece seat design, the sports style is more easily accepted by young consumers, and in terms of seat function, the main driver provides electric adjustment, seat heating and memory functions, while the co-pilot only provides manual adjustment, and the difference is more obvious.
The storage space and details are also in place, and the front drain cup holder can also be folded according to the needs. In terms of function, the new car will also provide mobile phone wireless charging function, more noteworthy is the driver monitoring function, with distraction monitoring, fatigue monitoring and expression recognition function, in the actual experience process, compared with the previous monitoring and recognition effect, there does not seem to be any upgrade in technology, from a functional point of view, practicality is general.
The design of the new gear handlebars is stylish and innovative, and the embellishment of the hollow and starry sky elements looks more textured. In the shift zone, it can also be seen that the vehicle will also be equipped with an automatic parking system, and a USB interface and charging interface are also provided under the hollowed out central handrail area to meet daily needs.
Looking at the overall style of the exterior and interior, people have to have more expectations for this car, the exquisite appearance kit, undoubtedly enhances the eye-catching effect, suspension system, the combination of front McPherson independent suspension + rear multi-link independent suspension, hard chassis tuning, making this compact SUV more playable.
Vapor potential view: a little bit of lemon flavor
