Compared with the domestic disputes, the actions of foreign manufacturers have given the answer – it is undoubtedly the most valuable new energy development direction at this stage. After entering 2015, the domestic hybrid car market has also undergone significant changes. It is no longer a plight of the Prius. At the beginning of the year, the BMW 530Le went on sale, and later the Volvo S60L E drive, BYD's Tang, plus the previous Zunrui, Qin, and foreseeable new cars, such as BYD's Song / Yuan, Corolla / Ralink mixed version, etc. . The domestic hybrid car market has gradually become a climate.
Conventionally, the value of mixing is of course energy saving and emission reduction, which is also the root cause of mixed disputes - it is always difficult to stand on this basis. Here, we might as well look at the angle to see the meaning of the "performance value" of the hybrid.
What are the advantages of fuel-efficient and hybrid models?
Usually we think that hybrids can save fuel, but the high price makes their low-cost cost advantage not outstanding. Manufacturers of hybrid models are more like playing concepts and "scam subsidies," but we ignore its performance! And this is just another highlight of the hybrid model.
Before we say the value of the hybrid performance, we must pay special attention to the performance characteristics of the motor. The motor and engine are diametrically opposed in some respects. For example, the motor can obtain peak torque at rest, and it can't be done by any engine in the world. Moreover, the torque of the motor can be easily made very large, and there is no need to add too much cost for this. This kind of characteristic can greatly compensate for the lack of power of the engine at low speed, and form a complementary effect, thereby achieving an improvement in overall performance.
Hybrid performance value one: initial performance improvement
There are many cases in this area, including Toyota that does not advertise performance. Many people may not feel "enough" when driving a Prius, Camry Zunru or Lexus ES300h. This is mainly based on Toyota's design philosophy, which puts the design core on energy saving rather than performance. For example, they are equipped with Atkinson engines that are not good at power. They look at 1.8L or 2.5L, but they are not big enough. Even so, the performance of these cars can still significantly exceed the same displacement of gasoline vehicles. For example, in PWR mode, the Prius's mid-to-low speed performance is not inferior to the 2.4L class, and the Lexus ES300h can provide enough confidence to the driver when accelerating at normal speed.
Hybrid performance value two: can easily achieve the ultimate performance improvement
Another feature of the motor is that it is easy to get "high performance". To put it bluntly, it is not enough to spend a minute to kill a petrol car. This is also the core reason why Tesla is such a "after the car", which can eliminate some "global high-performance cars" in performance. This feature is also applicable to hybrid vehicles, which can significantly improve the dynamic characteristics of the vehicle.
A more practical representative is the Accord Hybrid. Those who have tested the car have their power performance recognition (especially the low-to-medium speed), but it is only equipped with a 2.0L engine. The driving force feedback for most driving conditions is actually the performance of the motor rather than the engine.
A more gimmick example is naturally BYD's "history of the past." With dual motors and a 2.0T, BYD can boost Tang's acceleration performance to the level of the BMW X5M. Is BYD's technology surpassing BMW? Of course impossible, the mystery is that the performance advantage of the motor is far from comparable to the engine. On the other hand, with motor assistance, the design of the engine can also be “reinventedâ€. Designers do not have to consider the need for low-speed conditions to maximize their performance. Typical examples are the BMW i8. Why did a 1.5T three-cylinder car dare to run super? In addition to the motor, the 1.5T engine does not have to take care of the low speed, so that the power can be calibrated to a terrible 231 horsepower. Such an engine can have a very bad daily driving experience without motor assistance.
Hybrid performance value three: making the four-wheel drive easier and smarter
The traditional four-wheel drive is very cumbersome and must have a differential and a drive shaft. Then there are many specialties in the design of the differential, such as power distribution, limited slip control and so on. With the hybrid, the four-wheel drive can be easily realized by matching the previous driven shaft to the motor. The motor is small and can be placed above the driven shaft without the need for a drive shaft or a transfer case. The distribution of power can be realized by the ECU issuing commands to the motor. As long as the control program is properly designed, in theory it can obtain the most perfect power distribution characteristics.
Such an example would first think of BYD's Tang, which has proved the value of the hybrid four-wheel drive with practical actions. What is even more horrifying and more ideal is the legendary "six-engine four-wheel drive" - ​​each wheel is independently controlled by a motor to achieve the most perfect driving effect in theory. If you still feel that BYD is playing the concept, similar practices are becoming more common in global brands. The earliest Lexus RX450h does not have to say that the BMW i8 actually belongs to this category. The newly-launched Volvo S60L E-drive hybrid is actually a four-wheel drive in this way, and the performance card is dominated by a combination of enhanced performance (accelerated 5.6S + four-wheel drive).
Energy recovery boosts motor usage
Some people may ask, when the battery is running out of power, the hybrid system will increase the weight and reduce the performance. The reality is that even in the absence of charging the battery, most of the conditions of a car often use only a small part of the engine's "potential". At this point, the surplus energy generated by the engine can be used to charge the battery through the energy management system, so that the battery maintains a minimum reserve energy. When it is really necessary to use the start to speed up or overtake, the battery's reserve energy is enough to cope.
After this kind of working condition is over, the vehicle will enter the condition of constant speed, slow speed increase or deceleration, and the battery can obtain charging opportunities. This reciprocating, to ensure that the "performance advantage" of the hybrid can be played.
After all, is the hybrid model worth buying?
According to this theoretical analysis, it seems that the performance advantage of mixing is very valuable, but why people's feelings are not obvious? Personally think this is because it involves a problem with a model match. Since the mixing is still far from the popularization stage, the cost and capacity are not yet in place, and the manufacturer will naturally use it as high-end or high-class as possible. For example, the BMW 530Le, priced at 690,600 yuan, but the price after the subsidy is not much higher than the 528Li top with the same configuration and performance. Combined with the energy consumption advantage, the 530Le's cost performance has actually surpassed the 528Li top.
By the same token, Camry Zunrui feels that it is not cheap. For a car like Camry, it is meaningless to have more powerful power than 2.5L, so you don't think it is worth the extra money. But if the Camry Zunrui is equipped with the Prius hybrid, and then the selling price is not higher than the Camry 2.5L, is the price/performance ratio immediately available? In fact, the Ralink mixed version is like this kind of attempt, so it is likely to become the first hybrid car that really wins and costs.
in conclusion:
Having said that, we are definitely not denying the mixed energy saving and emission reduction advantages, which is still the soul of the hybrid. Here we emphasize the performance value of the hybrid, which is another easy-to-ignore aspect of the hint. This advantage is not obvious enough on Toyota's hybrid models, but in the new generation of hybrid cars, especially plug-in hybrid cars, the advantages are more and more prominent. In the next stage of the competition, it is entirely possible to become an important bargaining chip for the spread of popularity.
