In the context of the electrification transformation of the automobile market, hybrid models have gradually become one of the popular choices of consumers, because they can combine the advantages of traditional fuel vehicles and pure electric vehicles, which can not only meet the needs of daily travel, but also reduce fuel consumption and emissions, hybrid technology has attracted the attention of major car companies and consumers. However, the low temperature environment in winter has always been the performance killer of electric drive models, especially for the northeast of China, the performance and energy consumption of daily commuting vehicles have always been a concern for consumers.
Honda in the field of hybrid can be said to be a relatively early brand, since the nineties of the twentieth century, Honda has begun related technology research and development and launch, from the initial IMA single-motor hybrid technology, to today's first-class i-MMD dual-motor hybrid system, Honda has created and led the "electric drive-based" hybrid technology route. So, as the core model of Dongfeng Honda, the CR-V, and also equipped with the ***i-MMD dual-motor hybrid system of the strong electric intelligent hybrid version (e:PHEV &e:HEV), how does the car perform in winter?
In order to dispel the doubts and worries of consumers, not long ago, at the test site of the Extreme Inspection Center of the China Automotive Center in Yakeshi, the new generation CR-V E:HEV and CR-V E:PHEV were tested for the user's daily car use in winter, where the average temperature in winter is lower than -20 and the lowest temperature is lower than -40, which is undoubtedly a severe challenge for the performance and energy consumption of the vehicle.
The test challenge simulation restores the problems that consumers are pressing about in winter, especially the problems of daily commuting in severe cold weather, such as the energy consumption level of the vehicle, the heating efficiency of air conditioning, the handling and safety of winter ice and snow road travel, and other common problems. In the end, Dongfeng Honda's CR-V e:HEV and CR-V E:PHEV demonstrated the technical value of Dongfeng Honda's strong electric intelligent hybrid technology brand of "understanding energy saving and performance" with excellent performance of the first-class i-MMD high-efficiency dual-motor hybrid system, chassis and body, and successfully passed the challenge with excellent results.
Challenging vehicle energy consumption in extreme cold Low energy consumption leads to better economy.
The energy consumption of winter hybrid vehicles has always been a major concern for us, and this time, the new generation CR-V E:HEV and CR-V E:PHEV have been tested for energy consumption. The PHEV feed fuel consumption and HEV comprehensive fuel consumption test simulated the road conditions of cities, national highways and mountainous areas in low temperature environments. In order to ensure that the test data is closer to life, the air conditioning of the test vehicle during driving is set to 26, the wind speed is the maximum, the wind direction is horizontal, and the external circulation.
It is said that the energy consumption of the vehicle in cold areas will be consumed quickly, and it is seriously discounted compared to normal temperatures, but what people did not expect is that the fuel consumption data of the new generation CR-V E:PHEV in the feeding state is 501L 100km (WLTC official standard feed fuel consumption 5.)81L 100km), which is 14% lower than the official WLTC data. The all-new CR-V e:HEV has a combined fuel consumption figure of 669L 100km (WLTC official standard comprehensive fuel consumption 6..)44L 100km), compared with the WLTC official standard data is only more than 39%。Such a surprising energy consumption data can be regarded as the leading level in the same class, which can save users more expenses on a daily basis.
Such good economic performance is due to the fact that this car is a hybrid car, and its motor adopts a parallel-shaft dual-motor structure, and the optimization of the structure brings about a further strengthening of the torque of the motorAnd it can realize the direct connection of the engine in two gears, and the power and economy are very good, which can improve the fuel economy while meeting the power.
At the same time, in order to further improve power and fuel economy, Honda upgraded the manifold injection system used to provide fuel to a 35MPa direct injection system in the engine of the high-efficiency two-motor hybrid system. The in-cylinder direct injection system atomizes the fuel to finer particles, and can achieve 4 injections of fuel in a single cycle, which can make the gas mixture in the cylinder more uniform, and the fuel particles are not easy to adhere to the cylinder wall, and the combustion speed is faster, through combustion optimization. Not only does it reduce fuel consumption, but it also reduces the amount of polluting gases emitted.
The vehicle is fully controlled in the snow and ice.
As we all know, the vehicle is very prone to loss of control and traffic accidents on such low-adhesion roads with ice and snow adhesion, so the handling performance of the vehicle is very important for the user. In this challenge, the new generation CR-V E:HEV and CR-V E:PHEV demonstrated excellent handling performance in the face of demanding conditions.
In the face of the increasingly complex vehicle environment, in view of the two working conditions of pedestrian crossing with the highest accident rate and electric two-wheeled vehicle crossing, the "Emergency Avoidance Challenge in Extremely Cold Scenarios" was created this time to test the handling and safety avoidance strength of the vehicle in extremely cold scenarios. During the test, we saw that the CR-V E:PHEV was able to travel at 45km h on snow and ice, and was able to cross at 42Evasion smoothly at a speed of 8kmh;When driving at a speed of 35 km h, when an electric two-wheeler crosses, it can travel at 29The speed of 7km h is smoothly evaded.
The CR-V e:HEV also performs well, driving at 45 km h on snow and ice, and being able to cross at 43 km/hSmooth dodge at a speed of 2kmh;Traveling at a speed of 35kmh and being able to cross at 30 when encountering an electric two-wheelerSmooth dodge at a speed of 2kmh;And the whole driving process is smooth and smooth, and there is no contact with the dummy or two-wheeled vehicle in the whole process, showing perfect handling performance. The vehicle can achieve such a sensitive and stable response, which can greatly reduce the occurrence of such safety accidents in daily life, and escort the safe travel of drivers and passengers.
In the low-attachment handling challenge, we can see that the new C-V E:HEV and CR-V E:PHEV still perform very well on the two-kilometre-long snow handling track.
The car demonstrated outstanding handling performance in successive curves such as U-shaped low-speed corners, high-speed corners and combination corners on the snow and ice control track, with fast response and strong power in a straight line acceleration. The braking before entering a corner allows the vehicle to brake efficiently and achieve an ideal cornering speed. The steering is equally sensitive, which allows the vehicle to respond quickly in successive corners and to tackle snow and ice with ease. When the vehicle oversteers, the electronic assistance system responds in time to help the driver find the best line to pass quickly.
The best lap time for the new CR-V e:PHEV is 1 minute 9 seconds, while the new generation CR-V e:HEV has a lap time of 1 minute 07.4 seconds. Judging from the strong power of the vehicle and the smooth performance when cornering, it can bring more driving peace of mind to users in the north in winter and users in the south who often drive on low-attachment slippery roads.
Finally, the new generation CR-V E:HEV also carried out the vehicle's climbing challenge, the CR-V e:HEV can start stably on a half-low adhesion ice surface with a slope of 20 degrees, and the vehicle also achieves rapid forward and braking response with the operation of the driver, and the climb is completed in only 6 seconds. With such excellent performance, I believe that in daily life, especially in the case of ice and snow in the basement in winter, the vehicle can also be able to climb the initial stage, bringing more driving confidence to users.
The performance of the all-new CR-V e:HEV and CR-V e:PHEV in this series of vehicle handling challenges is mainly due to the excellent power delivery of Honda's i-MMD hybrid system, the stability of the chassis suspension, and the excellent tuning of the overall body control. It achieves best-in-class fuel economy with fast acceleration and excellent sporty performance.
Vehicle Thermal Management Challenges The driving environment is fearless and cold.
During the cold winter months, users want a comfortable and warm driving environment. In the air-conditioning comfort test, the vehicle was first left for an overnight stay below -25 nights, and after one night of resting, the vehicle was covered in snow and the glass was frosted.
At this time, the first low-temperature cold start test was carried out in the early morning, and when the engineer pressed the start button, we found that the vehicle could respond instantly and start rapidly. At the same time, the air conditioning defrost test shows that the front windshield has changed significantly, and the visual area gradually increases, which is enough to indicate that the vehicle has good defrost performance.
In the air conditioning comfort test during simulated driving, after the vehicle is warmed up and the temperature inside the vehicle is -13In the case of 7, the engineer set the air conditioner to 26, the wind direction is horizontal, the wind speed is maximum, the external circulation, and the rear air conditioner is turned off. We found that the air conditioner of the new CR-V e:PHEV heats up quickly, reaching 26 degrees after 2 minutes and 50 seconds of turning on the air conditioner. This means that when users go to work in the morning, while sorting out their belongings, the temperature in the car can reach a comfortable state for the human body, improving commuting efficiency. At the same time, at the end of the 30-minute test, the temperature inside the car reached 436. This also shows us the extremely strong heating capacity of the vehicle.
It is worth mentioning that users can also remotely turn on the air conditioning function in advance through the mobile phone APP, which can be set to the appropriate temperature in advance, so that we can adjust the temperature in the car when we are ready to go, so as to ensure that there will be a comfortable environment and a safe driving vision when we get into the car.
Epilogue. The new generation of the CR-V E:HEV and CR-V E:PHEV in this challenge deliver excellent energy consumption and performance, while achieving data close to official calibration in extremely cold environments, compared to other brands, which often have false standards. It demonstrates Honda's technical maturity and reliability, as well as the stability of its performance in harsh environments. Dongfeng Honda CR-V E:HEV and CR-V E:PHEV have passed a series of tests, which not only dispelled the worries and doubts in the hearts of consumers, but also confirmed their excellent performance strength.
