[car home Original Test Drive] Looking back a year ago, when the second generation of Changan (|) was officially listed, the stunning appearance made you stunned. I have to say that such an exaggerated and bold design really conforms to the public’s aesthetics, and Changan has made its own style. After a year, Yi Dong Blue Whale Edition came to us again. Although it didn’t surprise us in appearance this time, it quietly changed inside.
Changan Yidong Blue Whale Edition’s 1.4T engine this time comes from Changan Blue Whale NE power platform, and it has more backbone in the face of competing products. First of all, let’s talk about Changan Blue Whale NE power platform, which is positioned as a medium and small displacement engine. Under the effect of modular concept, it can be compatible with engines with displacement between 1.0L and 1.8L. If necessary, it can also be equipped with front-end technologies such as 48V, PHEV and ethanol fuel, and it also meets the increasingly stringent national VI emission standards.
● Power system/test drive experience
The 1.4T engine of Changan Yidong Blue Whale Edition has a slight improvement in parameters compared with its own 1.5T(156 HP /225 Nm), and has certain advantages compared with competing products, even better than the engine book data of some joint venture brands. In terms of transmission, it is equipped with a 7-speed wet dual-clutch gearbox.

The book data of the engine is excellent. What is the actual performance? Theoretically, the maximum torque of 260N?m starts to break out at 1500rpm, and the low torque should be good, but the engine is more willing to pull the speed above 2000rpm, and it is the stage of its force after intuitively feeling 2000rpm. Earlier torque burst can make up for the lack of low torque of small-displacement engines and create a lighter driving experience. At the same time, the accelerator pedal is light and sensitive at the beginning, and it is easy to follow cars on urban roads, and basically the second half of the accelerator is not needed.
This 7-speed wet dual-clutch gearbox has good ride comfort during daily driving, and there is basically nothing wrong with daily driving except a little setback in frequent switching between the first and second gears. Although the power connection of the dual-clutch gearbox is not as smooth as that of the AT gearbox at the beginning, according to the performance of most dual-clutches in the market at present, the gearbox mounted on Yidong is indeed slower than the common dual-clutch gearbox.
At the intersection of traffic lights, the green light lights up to release the brake, and the power connection of the gearbox is a little slow. At this time, you have to give a foot of oil, and it will start slowly and leisurely. If the throttle is given too much, it will run forward again. Especially when turning around, frequently switching between D and R gears, the gearbox always feels a beat slow. When accelerating rapidly, the first gear rises to the second gear and even has a power vacuum period of about 1 second, which wastes a lot of acceleration time.
After speeding up, the gearbox seems to have changed its personality, judging the driver’s intention more accurately, and being able to shuttle through the city with a 158-horsepower engine. After engaging in the S gear, the throttle response is more sensitive, and the engine is willing to stay at a high speed and wait for your instructions, but there is a process of power transmission to the wheel.
Yidong chassis has a good thick feeling and solid feedback. In contrast, the adjustment of the suspension is mainly based on comfort. The small bumps on the daily road surface can be well resolved, and it can be easily dealt with in the face of speed bumps. However, when passing at a faster speed, the longer suspension stroke will still have some redundant jumps. In addition, the lateral support force of suspension is not its strong point, and the body roll is more obvious in fast doubling and cornering.
The steering wheel is moderate in size, full in grip and light in steering, which is suitable for female drivers. However, the strength of the steering wheel will not sink with the increase of the vehicle speed, and it will not sink after being engaged in the S gear. You need to hold the steering wheel tightly when driving at high speed.
In terms of noise, it has a certain improvement compared with the old models. When driving at a speed of 80km/h in the city, wind noise and tire noise can be controlled within a good range. When driving at a high speed of 120km/h, the engine speed is high (2600rpm), and the engine noise has certain influence on the front passengers.
The new 1.4T+7-speed dual-clutch powertrain with Yidong Blue Whale version is still biased towards urban households, so it is difficult for you to find sports characteristics in it. In fact, the manufacturer knows the positioning of this car very well. It is just a family car. Treat it gently. It serves you proudly. If you drive hard, its performance may not make you so satisfied.
