Song PLUS DM-i super hybrid SUV is launched, the terminator of fuel vehicles opens a new era of "fast, economical, quiet, smooth and green"

91che once summarized the "impossible triangle" of hybrid vehicles, that is, a hybrid vehicle cannot have the three characteristics of "high performance", "low fuel consumption" and "low cost" at the same time. Basically, if one of them can be achieved, it can pass the product demonstration and be put on the market. If two of them can be achieved, it can be said to be an excellent hybrid vehicle design.

However, 91che now has to announce with mixed feelings that this theory no longer applies to BYD.

On March 25, the world's first wide-body super hybrid SUV - BYD Song PLUS DM-i was officially launched. With the support of the new super hybrid technology, the subversive engine and electric motor collaboration mechanism has brought the five advantages of "fast, economical, quiet, smooth and green" to this new model. It not only has the characteristics of high performance, low fuel consumption and low cost, but also makes up for many common shortcomings of hybrid vehicles in the past in the price range of 140,000 to 170,000 yuan. With its outstanding driving quality, it has become the most powerful disruptor in the field of hybrid vehicles.

How did BYD Song PLUS DM-i do it?

Low cost and low fuel consumption, Xiaoyun engine has its advantages

At the Guangzhou Auto Show not long ago, BYD unexpectedly released an engine - Xiaoyun 1.5L - during the launch of its major new energy technologies.

Some friends must be asking, Volkswagen has directly announced that it will no longer develop new fuel engines, and the former industry leader has directly announced GG. Why is BYD, which has already made a name for itself in the field of pure electric vehicles, still promoting fuel engines?

The reason is simple and straightforward - because this Xiaoyun engine is an engine specially designed for electrification and is the core of BYD's DM-i super hybrid technology. In the transition from fuel to electric evolution, hybrid technology still has a bright future.

Hybrid technology was recognized by consumers earlier than pure electric vehicles, and its complexity is much higher than that of pure electric vehicles. Pure electric vehicles are flourishing, but previously only two Japanese companies, Toyota and Honda, have produced hybrid technology.

Under the current general trend, pure electric vehicles will indeed be more popular with capital and policies, although they currently show a situation of long strengths and short weaknesses. Previously, Toyota and Toyota's hybrid vehicles, with excellent design and tuning, can take into account some of the advantages of fuel vehicles and pure electric vehicles.

The intervention of the motor in the starting stage greatly improves the acceleration of the hybrid vehicle. In the low-speed and high SOC stage, the car is an electric car driven by a motor.

At low speed and low SOC, the engine can be used as a range extender to charge the battery, ensuring that the internal combustion engine operates in the optimal fuel efficiency range. At high speed, the engine also participates in the driving work through the clutch, ensuring power while also ensuring that the engine operates in a high efficiency range.

Through this flexible adjustment strategy of series-parallel connection of the engine and the motor, hybrid vehicles can have the characteristics of electric vehicles' agile and smooth power and low operating costs, without suffering from the range anxiety of pure electric vehicles.

The disadvantages are of course obvious. First, the design and adjustment are extremely difficult. Second, the coexistence of the engine, motor and battery also pushes up the manufacturing cost of the entire vehicle.

To be honest, the THS II and IMMD technologies of Toyota and Toyota are indeed time-tested. However, compared with the fuel vehicle version, the high price of the hybrid version makes it seem not worth it - users have to drive a million miles before they can make up for the high price they paid before from the low fuel consumption.

In other words, in the face of high costs, the low fuel consumption advantage advocated by the two Toyota hybrids is actually of little significance.

From cocoon to butterfly, BYD's super hybrid technology finally takes off

Because the overall costs of the two Toyotas are high, BYD's DM-i technology has an opportunity to completely subvert the industry.

As 91che said before, because its super hybrid technology breaks the "impossible triangle", it provides high performance while taking into account low fuel consumption and low cost.

Here we talk about BYD's Xiaoyun 1.5L engine designed specifically for hybrid power. Because it has abandoned the fuel platform, the Atkinson cycle gives it a compression ratio of up to 15.5 by increasing the expansion ratio.

Why can't other manufacturers' engines do this? Because they are not hybrid-specific platforms and have to use the traditional Otto cycle for performance.

With the support of the motor, the entire vehicle power system can focus on improving thermal efficiency. Finally, the thermal efficiency of BYD Song PLUS DM-i's Xiaoyun 1.5L engine reached a world-leading 43%. This car, which consumes only 4.4L of fuel per 100 kilometers, can accelerate from 0 to 100 in just 7.9 seconds, and its power performance is not inferior to that of a 2.0 T fuel car.

In addition, as a dedicated hybrid engine, the Xiaoyun 1.5L simply eliminates all front-end wheel system accessories and leaves all work other than the engine to BYD's three-electric system, which is its specialty. While further increasing the thermal efficiency of the engine, it greatly reduces the amount of detailed development of the engine, reduces the overall cost, and makes the overall power system more stable.

This is also the reason why BYD dares to provide Song PLUS DM-i with a 6-year, 150,000-kilometer three-electric lifetime warranty service for the first non-operating owner.

In fact, 91che believes that it is no accident that BYD has become a dark horse in the field of hybrid technology. As the only car company in the world that has insisted on walking on two legs of fuel vehicles and electric vehicles for more than ten years, it has also conducted in-depth research on engines and three-electric systems, and finally created the Xiaoyun engine that dominates hybrid vehicles.

Judging from the core configuration performance alone, BYD Song PLUS DM-i, as a wide-body SUV, is already a model with unparalleled product strength in the 140,000-170,000 yuan price range. Of course, with BYD's consistent ethics, it will not deliberately hold back on driving quality just because of the price.

Fast, economical, quiet, smooth and green, DM-i super hybrid leads the new trend of electrification

The entire series is standardly equipped with a 12.8-inch 8-core adaptive rotating floating Pad, a 12.3-inch LCD display, mobile phone NFC car key, Dirac 9-speaker smart music cockpit, OTA remote upgrade, tire pressure digital display, 360° high-definition holographic transparent image, double-layer sound and heat insulation glass for the front row and front windshield, 6 airbags in the front and rear rows, electric adjustment of the driver's seat, electric tailgate, VTOL 220V power output, mobile power station function, etc. None of these mainstream configurations of the BYD series are missing, and all that can be given is given. We have seen similar configurations that enhance the sense of luxury and intelligence on models such as BYD Han.

In addition to these conspicuous configurations, BYD Song PLUS DM-i is also attentive in invisible places. As a high-quality super car, Song PLUS DM-i has excellent NVH tuning, and the whole series is equipped with double-layer sound insulation and heat insulation glass for the front row and front windshield, acoustic package, etc., which brings a super quiet driving experience.

The Song PLUS DM-i flagship version uses an 18.3kWh large-capacity lithium iron phosphate blade battery, with a pure electric range of 110km, and supports DC fast charging at public charging piles. If it is only for daily short-distance commuting, you can use it as an electric car; when the battery is low, the fuel consumption of the Song PLUS DM-i is only 4.4L/100km, and the cost of less than 0.3 yuan per kilometer is not much more expensive than electric vehicles.

All Song PLUS DM-i models can be issued green license plates and enjoy preferential policies such as purchase tax and no traffic restrictions. 91che believes that considering its cost-effectiveness and low fuel consumption, Song PLUS DM-i should be popular even in areas without license plate restrictions.

To sum up, 91che believes that Song PLUS DM-i is an excellent low-fuel-consumption model with a smooth and quiet driving experience like an electric car, and it has no range anxiety at all. In the price range of 140,000 to 170,000 yuan, it completely balances the cost of using the car, selling price, driving experience and quality. In this sense, it can indeed be said to be invincible.
