Unconsciously, 2021 is nearing the end, and the Year of the Tiger 2022 is coming. In the face of carbon neutrality goals, independent car companies began to rivet enough to carry out the electrification of passenger cars, especially in the SUV market, all kinds of blue-brand, green-brand hybrid vehicles will also follow, NEDC test conditions The minimum fuel consumption is only 0.9L/100km, which will further consolidate and expand the influence and share of domestic vehicles in the field of 130,000-200,000 segments.
●BYD Song MAX DM-i
As the leader of hybrid vehicles, one car and three SUV models of the BYD DM-i series have a very good market performance and user reputation. In 2022, BYD will also fully expand the product lineup of DM-i green hybrids, and the first thing to meet with you is this Song MAX DM-i model.
At present, BYD has officially released the official map of this Song MAX DM-i, and added a new "upgraded roof" model, which is expected to be officially released in the first quarter of 2022. According to the declaration information of the Ministry of Industry and Information Technology, the comprehensive fuel consumption of the car NEDC test is 0.9L/100km (the battery is fully charged). You know, this car is six/seven-seat like Tang DM-i, the practicality is full, and the price is expected to be controlled within 150,000.
In addition, next year, BYD will also launch the Han DM-i model, after replacing the same hybrid system of Tang DM-i, this plug-in hybrid car will have better fuel economy than the active Han DM, and the price is also expected to further explore.
●Chery Tiggo 8 PLUS Kunpeng E+
Since the first half of this year, the relevant information about Tiggo 8 PLUS Kunpeng E+ has always been the focus of media and consumer attention, the biggest difference between the car compared to the active Tiggo 8 series is the replacement of Chery's newly developed Kunpeng E+ plug-in hybrid system, which is another domestic hybrid system representative after BYD DM-i and Great Wall DHT.
Unfortunately, this green card plug-in mixed car has been "difficult to produce", once said that it was listed in October, and later said that it was listed at the Guangzhou Auto Show in November, and now it seems that "Dove" will not be able to officially meet with the majority of consumers until 2022.
From the hardware point of view, Chery's Kunpeng hybrid DHT is actually similar to the BYD DM-i, Great Wall DHT, are electrified engines, plus the front axle dual motor drive, the difference is that Chery in the engine output end of the use of three-stage gear transmission mechanism, while ensuring economy will further strengthen the high-speed explosive force, with P4 bridge (rear axle motor, electric four-wheel drive), in the power output and fuel economy to achieve a better balance.
According to official data, the 1.5T engine and three motors of the Tiggo 8 PLUS Kunpeng E+ can achieve a comprehensive power of 341kW, a comprehensive torque of 735Nm, a 0-100km/h time of 4.9 seconds, and a comprehensive working condition fuel consumption as low as 1.0L/100km. Of course, this is only the data when the battery power is high, if it is not charged at all, the performance and fuel consumption will be discounted, and it is expected that the power loss and fuel consumption are similar to Tang DM-i, at about 6.0L/100km.
● Geely Hoshikoshi L Hi-X
Like several peers, Geely Automobile also sees great potential in the field of hybrid vehicles, and for the first time in the second half of this year, a new generation of Thor power architecture was released, the most core of which was this Thor Hi-X hybrid system, which will be served on the Star-Etsu L for the first time, and officially opened reservations on December 25 this year.
In fact, geely active many models have plug-in hybrid version, but are based on 1.5T + 7DCT magic changes, such as Lynk & Co 01 PHEV, Geely Binyue PHEV, plug-in single motor in the charging conditions can indeed maintain a relatively good fuel economy, but without charging conditions then fuel consumption will rise significantly, which is actually the biggest gap between the German hybrid idea and the Japanese hybrid idea.
Therefore, in theory, the hybrid system of The Star-Over L Raytheon Hi-X should be regarded as the second generation of products, and its engine part is still the 1.5TD inline three-cylinder engine, but after the electrification transformation, the book data has been weakened to 150 hp / 22 Nm, with the increase in compression ratio, the thermal efficiency has increased to 43.32%, which is already a special engine for hybrid vehicles.
More importantly, in the "transmission" section, the Thor Hi-X does not have a separate transmission mechanism, but integrates a three-stage planetary gear transmission mechanism into two coaxial drive motors, thus taking into account power shunting and electromechanical coupling. Official data show that the 0-100km/h acceleration time of the Hoshigoku L Thor Hi-X is 7.9 seconds, and the maximum endurance is 1300km when full of fuel. Unlike the Tiggo 8 PLUS Kunpeng E+, this car should have a small battery and a blue card.
●SAIC Roewe Totoro
SAIC Passenger Car also has an active plug-in hybrid system and serves on roewe eRX5, MG 6 PHEV and other models, but this Totoro is different in terms of product positioning and power system. The declaration information shows that this car is not only the size of a small SUV, the length, width and height are 4440/1810/1634mm, the wheelbase is 2625mm, and it is a blue card, the estimated price is 100,000-120,000, which may be the cheapest hybrid car in 2022.
In the power part, roewe totoro is equipped with a 1.5L self-priming engine with a model of 15S4C, its maximum power is 88kW (120Ps), and the same model of engine is also used on the current Roewe i5, and the power data is the same, which itself is an Atkinson cycle, and then do an electrification transformation, cancel the pulley train can be transferred to the hybrid.
And in the electric drive module, the second-generation EDU mechatronic coupling system in service has already realized the mechatronic design, but that. Compared with the first generation of the ISG motor that canceled the engine end, and at the same time electromechanical coupling and power shunting for the engine and TM motor through the three parallel shaft gearbox (the above several are dual motors, or even three motors), the result of hardware simplification is that there are higher requirements for the gear switching logic, otherwise it is difficult to ensure the smoothness and fuel economy when not charging.
●Changan UNI-K iDD
In September this year, Changan UNI-K also launched the first green card plug-in mix, named UNI-K iDD, this car is the first model equipped with blue whale IDD hybrid system, with a large-capacity battery pack, on the green card, the official revealed that its pure electric mileage reached 130km, competitors pointed to Tang DM-i.
In fact, as early as Changan Automobile on the UNI-T first display of the Blue Whale NE powertrain, the official revealed that this 1.5T engine has a hybrid special version (model JL473ZQ6), first the wheel train cancels the belt, and then through the precision VVT technology of the intake and exhaust to achieve the full-scene Miller cycle, with exhaust gas recirculation, electronic thermostat and the simplification of the pulley train. Officials say its book figures have been compressed to 170 hp/260 Nm, but the maximum thermal efficiency can reach 45%.
However, unlike BYD DM-i, Great Wall DHT, geely Hi-X, The Changan iDD hybrid system does not use the electromechanical coupling module of multi-axis dual motors, but integrates a drive motor in the front end of a six-speed three-clutch transmission, which belongs to a more typical P2 layout, and is often used in German cars such as BMW 535Le, Passat PEHV, audi A3 and so on.
From the structural point of view, this hybrid system mainly relies on large-capacity batteries to reduce comprehensive fuel consumption, and if there is no charging condition, the economy is not as good as the RAV4 dual engine E+, Tang DM-i and Macchiato DHT-PHEV of the Japanese "peak shaving and valley filling" idea. Objectively speaking, compared with this UNI-K iDD, the new CS75PLUS (1.5T+8AT) and UNI-V (four-door coupe) launched by Changan in 2022 are more worth looking forward to.
●Summary:
There is no doubt that various HEV and PHEV models are replacing pure fuel vehicles as the mainstream choice for a long time in the future, and specific to the subdivision field, compared with the P2 hybrid of the german single motor, consumers still have a higher recognition of the Japanese style of dual-motor hybrid. The reason is also very simple, because the design idea of electric drive and cancellation of the transmission can emphasize the high efficiency of the electric drive to the greatest extent, so that the engine is always in a stable speed / complex working condition, the tube is not blocked, the tube blue brand green card, even if it is not charged, the fuel consumption is far lower than that of pure fuel vehicles, but also take into account the practicality of fuel vehicles, which is the core competitiveness of BYD DM-i, Great Wall DHT, Toyota THS, Honda i-MMD, and also the core competitiveness of hybrid compared to pure electricity / fuel.
