Not long ago, BYD Han officially started pre-sales. The hybrid DM version is very eye-catching. The front face is slightly different from the EV version. After all, there is an engine that needs air intake, and a closed grille design cannot be used.
The maximum horsepower of the system reaches 436 horses, the peak torque is as high as 650Nm, and the acceleration time from 0 to 100 kilometers is 4.7 seconds. Several core power parameters are basically top-notch plug-in hybrids. Of course, the price of 230,000 is also a domestic hybrid. ceiling.
As the top new energy manufacturer in China, how is BYD’s hybrid different from Toyota and Honda? Is there any advantage in pitting the Han DM against the Accord Hybrid and Camry Twin Engine?
1. Camry hybrid, mainly oil, the most extreme thermal efficiency
Toyota is one of the earliest car companies to research hybrid technology, starting from the launch of the first-generation Prius in 1997 , the architecture of Toyota's THS hybrid system has been basically established, and the rest is to tinker with this architecture.
Toyota’s architecture construction logic is very simple. Why do we want to build a hybrid in the first place? In that era, the first priority was definitely to save fuel, because there were no strict regulations or exaggerated subsidies as now. Emissions and points were secondary.
First of all, consumers must have enough reasons to accept it, and fuel efficiency is one of the easiest reasons for consumers to accept it. They also choose a small car like the Prius because consumers of this level are interested in it. Fuel consumption is more sensitive.
The core of Toyota's system is the E-CVT structure composed of two electric motors. Although it is also called a CVT, it is actually the same as the CVT transmission commonly used in Japan with a steel belt moving between two cone wheels. There is no direct relationship. Toyota probably named it this because it means continuously variable transmission.
Both of these motors can be used as generators or electric motors. Motor 1 is responsible for starting the engine and then charging the power battery. Motor 2 is responsible for engine driving under some working conditions and energy recovery. Of course, they can also work together under some working conditions.
Generally speaking, the logic of Toyota's system is that in areas where the engine's operating efficiency is not high, such as starting, reversing, stop-and-go at low speeds, the motor intervenes.
With the blessing of the motor, the engine is also liberated to be as efficient as possible, but some concessions can be made in terms of performance. It is also a 2.5L engine, and the hybrid engine uses the Atkinson cycle. .
The 2.5L Dynamic Force Engine hybrid engine used in the Camry Dual Engine has a thermal efficiency of up to 41. As a medium-sized sedan, the overall fuel consumption is only 4.1L/100km.
And whoever drives the hybrid car really knows. It is driven by an electric motor in the initial stage, which not only makes the start faster and less abrupt, but also has better NVH performance. The new generation system does not have a strong sense of engine intervention when accelerating, bringing a strong and smooth power output experience.
The most important thing is that traveling in urban areas can bring people a greater sense of satisfaction. When other cars face congestion and fuel consumption rises, Camry dual-engine owners can remain calm, and the motor-driven Frequent starts and stops are easier.
The significance that hybrid brings to users, in addition to saving "gas money" for a long enough period of time, the greater significance is to enjoy the pleasure of new technology and improve the driving experience.
2. Accord hybrid, mainly electric, enjoy the speed and speed
Honda has no choice but to engage in hybrid. After all, its "old neighbor" Toyota is really not easy to mess with, and the two compete with each other. For more than 60 years, I have already known the basics.
Honda must follow up on whatever Toyota does. After all, Toyota can cooperate with Volkswagen and sell the Aisin 6AT gearbox to Aisin, but it will never be so polite to Honda.
Toyota laid a lot of patent traps when developing the THS system to prevent Honda from taking a piece of the hybrid cake.
As a brand born on the track, what Honda is best at is constantly honing its technology under extreme conditions. Since Toyota has blocked the oil-based route, it might as well develop its own hybrid system.
Honda's system is actually similar to the current extended-range hybrid system. The engine-generator-battery-inverter-motor-rear axle are connected in series. That is, the main function of the engine is to drive the generator to the battery. Charging, the motor drives the vehicle to run.
Different from the extended-range hybrid, Honda has added a special clutch, and the engine can also directly drive the vehicle. Of course, it mainly runs at high speeds, solving the problem of low high-speed efficiency of the extended-range hybrid model. .
Since it is an extended-range structure, the requirements for motors and batteries are naturally higher. The dual-motor system used by the Accord Hybrid can drive the motor with a maximum torque of 315Nm and a maximum power of 135kW, while the combined power of the gasoline-electric hybrid can reach 158kW. This power output is already close to the Magotan/Passat's 2.0T? EA888 high-power engine. power.
Honda has also prepared large-capacity ternary lithium batteries to protect this system, which have a higher energy density than Toyota's nickel-metal hydride batteries.
The Accord Hybrid drives more like an electric car. After all, most working conditions are actually driven by electric power. It starts more quickly and picks up speed quickly in the middle. In addition, this generation of Accord has gone further. The seat position and heel position are lowered, making the overall control experience more prominent.
Judging from the market performance of the Accord Rui Hybrid, Honda's system has been a great success, and when the third-generation i-MMD was launched, its sales volume was already on par with the Camry's twin models.
Recently, Honda has also installed a new 1.5L hybrid system on the Lingpai. It seems that it is ambitious to challenge the big brother's status.
3. Han DM, gasoline and electricity coexist, and you can enjoy the blend of gasoline and electricity
Although Liangtian’s hybrid system is good, it has a fatal weakness, that is, it cannot be green-labeled. . Well, guess how much thought the research team that formulated the green card policy and subsidies put into excluding the HEVs in Liangtian through the subdivision rules.
So what should users who want to enjoy the fun of electric vehicles without suffering from range anxiety and want to use a green license do? The answer is plug-in hybrid models.
BYD Han DM is an outstanding representative of plug-in hybrid models. This is not surprising at all. After all, it is the world's second largest automobile manufacturer, and Tesla does not make hybrids.
And BYD has a long history of research and development of plug-in hybrids. In 2008, BYD mass-produced the world's first plug-in hybrid car, F3DM. Of course, this car is not very complete. , can only be regarded as a great attempt.
Now BYD's DM technology has developed to the third generation, and has broken away from the traditional plug-in hybrid concept. It no longer just provides users with a green card, just for use as a gas-powered vehicle, but Fully demonstrate the charm of the integration of oil and electricity.
Han DM is equipped with the latest DM-p technology. The newly added high-voltage BSG motor can directly start the engine and realize functions such as intelligent start and stop, auxiliary shifting, and sudden acceleration assist. These are all traditional fuel The "stubborn disease" of the car.
The intelligent start and stop of traditional fuel vehicles has been criticized, which greatly affects the driving experience. Han DM directly uses the motor to take over the start and stop functions, allowing the motor to be on call at any time, eliminating the trouble of starting and stopping traditional fuel vehicles. .
The addition of an electric motor also greatly alleviates the stalled shifting problem that traditional fuel vehicles are prone to, making the shifting process smoother. Needless to say, acceleration assist, after all, this is a mid-to-large flagship sedan that can accelerate from 100 kilometers to 100 kilometers in 4.7 seconds.
Han DM realizes the integration of three driving modes: fuel drive, EV, and HEV. It can be driven by pure fuel, pure electric drive, or hybrid electric drive like Liangtian, and HEV is strong The mixed mode can also switch between series and parallel, pushing the driving experience to the commanding heights.
4. Kung Fu Pai Case
Some people say that hybrid is destined to be just a transitional solution, but there is no doubt that before battery technology makes a big breakthrough, hybrid is also a pretty good solution. choose.
It is energy-saving and environmentally friendly, has an excellent driving experience, and does not have to worry about charging.
The Camry Dual Engine shows us what a fuel vehicle with extreme thermal efficiency looks like with the support of hybrid technology; the Accord Hybrid not only saves energy, but also has a good driving experience; as BYD, China's leader in new energy, brings users the experience of oil and electricity integration through Han DM.
All three have their own advantages. Of course, in terms of reliability, I still vote for Camry Dual Engine. After all, it has the largest installed capacity and the most mature technology.
Which one will you choose?
