With its avant-garde styling, rich configuration and excellent power system, each product can attract the attention of many users, and last month's UNI series models achieved excellent results of sales of more than 10,000.
Not long ago, Changan once again released a big move to launch the first UNI-K iDD equipped with blue whale plug-in hybrid model, we preemptively shared the test drive, and the colleagues in front of the test drive also praised the blue whale hybrid system.

What are the highlights of this blue whale hybrid system, and is Changan's first blue whale hybrid model UNI-K iDD really as good as colleagues say? Don't worry, this will let me answer them all for you.
First of all, let's first understand the technical characteristics of the Changan Blue Whale plug-in hybrid system, which is composed of four major units: the Blue Whale NE1.5T hybrid special engine, the Blue Whale three-clutch electric drive transmission, the large-capacity power battery and the Blue Whale iDD electronic control system.
Among them, the high-performance blue whale engine dedicated to 1.5T hybrid uses a series of new technologies such as Agile agile combustion system, intelligent thermal management system, Miller circulation, intelligent lubrication system, etc., which can achieve a maximum power of 125kW and a peak torque of 260Nm.
The drive motor, which works in tandem with the engine, also has technologies such as IGBT double-sided cooling and S-winding winding (to improve the efficiency of the motor system), with a maximum power of 85 kW and a maximum torque of 330 Nm, and a total torque of up to 590 Nm for the entire powertrain.
In the gearbox part, this blue whale electric drive transmission can achieve a maximum transmission of 98.5% and a comprehensive transmission efficiency of 90% through a series of black technology applications such as highly integrated wet three-clutch module, high-efficiency high-pressure hydraulic system and intelligent electronic dual-pump technology coupling.
Compared with the ordinary double clutch, this electric transmission realizes the engine, pure electric and hybrid modes by integrating the P2 motor module, and the motor module also adds a set of clutches in order to realize the switching of different hybrid modes of P2/P4, which is the origin of Changan Automobile's use of "three clutches". With it, to a certain extent, it solves some of the pain points in the current dual-clutch experience: such as the durability, stability and setbacks of the transmission.
When it comes to PHEV models, then its pure electric endurance is also an important parameter that cannot be ignored, Changan UNI-K iDD is equipped with a large-capacity battery with a capacity of up to 30.7kwh, and the pure electric mileage can reach 130km.
It is worth mentioning that this battery system not only supports AC and DC dual fast charging at the same time, but also considers many practical application scenarios, and can achieve a maximum of 3.3kW external discharge to meet the user's outdoor electricity demand.
Finally, in the electronic control system part, the Blue Whale iDD electronic control system can ensure that the engine, electric drive transmission and battery work together in the optimal efficiency range under the vast majority of working conditions through the application of multi-core parallel operation architecture, A-ECMS energy management algorithm and other technologies, and at the same time, the customization of power attributes can be realized, allowing users to intelligently combine driving styles by adjusting power parameters.
It is also the joint cooperation of these four major systems that makes Changan UNI-K iDD have a power transmission efficiency of up to 97%, and a comprehensive long cruising range of more than 1100km.
Here I also listed the parameters of the current four mainstream independent brands of their respective plug-in hybrid systems, and it can be seen that the Changan Blue Whale iDD hybrid system not only has advantages in the gearbox, but also has different degrees of leadership over other competitors in terms of the comprehensive power of the power system, power battery capacity, and pure electric mileage that are closely related to the car.
From a technical point of view, Changan Blue Whale iDD hybrid technology has indeed armed itself to the teeth, to actually experience this Changan's first blue whale hybrid model UNI-K iDD is still outstanding?
Thanks to the addition of the electric motor, what impressed me the most when driving the UNI-K iDD was the quietness of the ignition and starting, almost as quiet as a pure tram, and with the existence of a three-speed clutch, the smoothness at starting and low speed was very good.
The UNI-K iDD has three driving modes to choose from, namely EV, HEV and i-X modes, EV and PHEV are well understood, that is, pure electric and hybrid modes.
In the EV mode, UNI-K iDD has a pure electric mileage of 130km, which can fully meet the needs of a day's transportation in the city, and almost achieve the same tranquility as pure electric vehicles, with the characteristics of electric motor power output, you can hardly feel that you are driving a 2-ton car.
In heV mode, I recommend using it in long-distance or high-speed states, in HEV mode, UNI-K iDD can achieve a full fuel and full power range of 1100km, and in the state of power loss can still achieve 5L/100km fuel consumption. (At first I didn't quite believe that a 2-ton can have such excellent fuel economy, so there's a power-loss fuel consumption test waiting for it!) ）
Finally, the i-X mode, this mode can be simply understood as a user-defined mode, in the menu bar there are three preset options of surging power, long endurance, camping, in addition to this also support up to three custom modes, you can set the power style, kinetic energy recovery intensity, battery level and other parameters to adjust to meet the needs of different users.
The chassis tuning of the UNI-K iDD maintains the comfortable style of the fuel model, and its suspension can filter small bumps well for uneven test drives. If you encounter a large pothole, you can also feel that the suspension is actually able to pull the body, and it will not produce unnecessary shaking, and the riding comfort is very good.
Finally, the fuel consumption test was conducted, in which we selected 50% of the roads in the urban expressway and 50% of the congested sections to simulate the fuel consumption of UNI-K iDD in the daily car state under the state of power loss.
During the test, the air conditioner was adjusted to 24 °C air volume AUTO, it took a total of 3 hours to drive 100.5km, the average speed was about 33km/h, we measured UNI-K iDD comprehensive fuel consumption of 5.26L/100km, the driving computer showed 6.4L/100km, a model of more than 2 tons can achieve such a loss of power and fuel consumption, it is indeed very outstanding.
summary
As Changan's first Blue Whale hybrid model, UNI-K iDD has indeed achieved excellent experience in both technical armament and actual driving experience, it not only continues the avant-garde shape of Changan UNI series models, rich configuration, and the blessing of the hybrid system is also a result of 5.26L/100km in terms of fuel economy.
It can be said that with the blessing of the Changan Blue Whale Hybrid System, Changan UNI-K iDD has truly achieved an all-round player who can take into account both appearance, power, configuration and fuel consumption.
However, the last important factor that can affect the user's choice is the price, at present, Changan UNI-K iDD has officially begun pre-sale, its pre-sale price is 17.69-19.29 million yuan, just the pre-price can feel the full sincerity of Changan Automobile, expect changan automobile to give us a more surprising price when the follow-up listing, but also look forward to Changan UNI-K iDD follow-up can have a good market performance.
