Speaking of F1, ordinary people may feel out of reach with themselves. After all, there are only 10 or 20 people who can participate in F1 competitions every year, so we can hear and see F1 competitions, basically on TV.
However, although we cannot drive the racing car of F1, we can enjoy the civilian version of the technology that uses F1 racing and then goes down. For example, the GAC Honda model e:HEV car is equipped with the fourth-generation i-MMD hybrid system that Honda has matured in the F1 field and is now widely used in mass production models.
Many people may be confused when they come here, that is, can the hybrid system equipped with GAC Honda model e: HEV really be called the "F1 hybrid civil version"? If so, then what is the strength of this hybrid system of GAC Honda model e: HEV? With these questions in mind, let’s analyze them comprehensively.
First of all, if you trace back to history, then the Honda Hybrid was officially launched as early as 1997. Now after 25 years of technological accumulation and four generations of innovation, Honda Hybrid has attracted more than 4 million fans around the world, making it a complete "big salesperson" of hybrid models. Since 2015, Honda has been continuously collecting hybrid data from the F1 arena, and has continuously polished and iterated its own mass-produced hybrid system.
In the 2021 World F1 Grand Prix, the 23-year-old Verstappen drove the RB16B car of the Red Bull Racing team and won the F1 driver's annual driver's championship. The strongest hybrid system in history that drove him to be the RA621H hybrid engine developed by Honda. It was also after this that Honda's fourth-generation i-MMD hybrid system was officially born. Since then, the e:HEV model equipped with the fourth-generation i-MMD hybrid system has been given the title of "F1 hybrid civilian version" by car fans.
In fact, the RA620H hybrid system equipped on the F1 racing car of Red Bull has the same principles and characteristics as that of Honda i-MMD. They are all motors that can replenish energy and increase torque for the engine, and while avoiding the low-efficiency range of the engine, it reduces turbine hysteresis, and cooperates with braking force recovery and exhaust gas turbines to maximize the overall efficiency of the power system. Therefore, it is not unreasonable to compare the e:HEV model equipped with the fourth-generation i-MMD hybrid system to the "F1 hybrid civilian version".
After understanding that GAC Honda model e:HEV does have the characteristics of "F1 hybrid civil version", let's take a look at what is the strength of the fourth-generation i-MMD hybrid system equipped with GAC Honda model e:HEV?
1. The newly developed 2.0L engine
If a car is called a "good car", the engine must be the key. In terms of the model e:HEV model, GAC Honda also used it with a newly developed 2.0L direct injection engine. You should know that this 2.0L engine is equipped with 350Bar high-pressure injection and up to four-stage injection technologies. At the same time, its thermal efficiency has been increased to 41% of the world's top, which will also give the vehicle better power performance.
In addition, the engine's air-fuel ratio torque has been increased by 30%. Combined with the newly developed high-rigid crankshaft and the new 2-time balancer , it can greatly improve performance while further improving fuel consumption and silentness. For consumers, this change may not be able to be perceived by the naked eye, but if we have the opportunity to conduct in-depth test drives, we will definitely be able to understand the strength of this engine, and this is precisely the most intuitive embodiment of Honda as a "technical home".
2. Further optimization of the electric drive hybrid mode
Speaking of Honda's electric drive mode, it was actually the first hybrid power source of F1 racing cars. At that time, they developed with the goal of the best power output and the best fuel efficiency , and this is also the source of Honda's concept of building an i-MMD dual-motor hybrid system.In the end, they focus on three types: EV pure electric mode, HYBRID hybrid mode and engine direct drive mode, and at the same time, they use the motor direct drive priority to play to their strengths and avoid their weaknesses, so that the power and energy consumption efficiency of the entire hybrid system can always be maintained at the optimal level.
It is also under the influence of the F1 racing hybrid concept that the optimization of the fourth generation i-MMD hybrid system is mainly to expand the coverage of the electric drive mode, allowing the three driving modes to be switched flexibly and quickly. The purpose is to allow the motor to participate more in the drive, and to quickly improve the acceleration performance of the vehicle, especially at low speeds, through the flexible use of battery power and the early intervention of engine power generation.
Just recently, we were lucky enough to test drive this model e:HEV model. When we actually drove it, the moment we pressed the accelerator pedal, the power response of the whole car to you is indeed much stronger than that of previous hybrid models and fuel versions. It is no exaggeration to say that at that time I even felt that I was driving a car with a displacement of more than 3.0L, which shows how powerful the power performance of the model e:HEV is.
3. Strong comprehensive upgrade of PCU/IPU/E-CVT
When it comes to the comprehensive upgrade of PCU/IPU/E-CVT and other components, you may not understand what they are. Simply put, the so-called comprehensive upgrade is to further integrate and miniaturize to achieve the purpose of improving performance and improving fuel consumption.
In addition, the battery is optimized by increasing the power of inverter , lightweight aluminum high-voltage cables, and optimized capacity expansion. Finally, Honda has also upgraded the E-CVT and optimized the shock absorber structure to achieve and improve the vehicle's low torque range performance.
In short, this upgrade basically plays an optimization role, which has helped greatly improve vehicle performance and fuel economy, and also reflects the "craftsman spirit" that Honda continues to deepen its efforts in the field of hybrid technology.
Finally, in addition to having a powerful and new fourth-generation i-MMD hybrid system, the new Honda Architecture new architecture is also its highlight.
First of all, this new architecture will pay more attention to the safety of road traffic participants, including pedestrians, and enrich the active safety configuration. For example, the model e:HEV model is equipped with 10 airbags, pedestrian protection system and Honda SENSING safety super sensor system. These are rare among models of the same level and price.
Secondly, the model e:HEV has also greatly improved the body rigidity, and is upgraded for strength, lightweight and structural strengthening. For example, the entire vehicle uses high-rigid thermoformed steel, accounting for 10.6% of the body, and the twisted and rigidity of the rear body of the model e:HEV is 10% higher than that of the gasoline version, which naturally allows the model e:HEV to better ensure safety while having excellent performance.
Finally, this new architecture also gives the model e:HEV the sports car level 1415mm ultra-low body. When the vehicle is driven, this ultra-low center of gravity and low sitting posture will give the driver a more "fighting" driving desire. Therefore, in essence, Honda is still very sporty in its bones, and this is the real reason why so many people are willing to choose to buy a Honda car.
is written at the end:
In short, through GAC Honda model e:HEV's excellent product strength, we can see that in the current 200,000-level joint venture hybrid model market, Honda hybrid can indeed be regarded as the best solution for buying a car at the moment. After all, whether it is the halo of the "F1 hybrid civilian version" or the visible product advantages of the model itself, the model e:HEV is telling the world that I am the new "value benchmark" in the compact family sedan market. So in the face of such a comprehensive and cost-effective GAC Honda model e:HEV model, do you still miss it? Leave a message in the comment area and let’s talk about it together.
