There is no contradiction between youthfulness and energy saving, but complement each other. For young consumers, the lower the energy consumption of a vehicle, the lower the cost of use, which is undoubtedly a happy thing to see. So, how to reduce the energy consumption of a car?
From the source, there are two ways: 1. Electric vehicles, which is also a major trend at present; 2. Reduce engine energy consumption, which is a major problem at present . In this regard, we might as well introduce a term-thermal efficiency. In the engine field, this is undoubtedly an important indicator to measure its economic performance, because the higher the thermal efficiency, the higher the heat conversion rate. At one time, Toyota's Dynamic Force series 2.5L engine led the field of fuel vehicles with a thermal efficiency of 40%. However, Changan Automobile caught up. The 1.4T Blue Whale engine born under the Blue Whale NE power platform has reached 40% thermal efficiency, keeping pace with Toyota!
At present, this Blue Whale 1.4T will be mounted on the Changan CS35 PLUS and Yidong models. But we also need to know that thermal efficiency is certainly an important indicator to measure the fuel economy of an engine, but whether a car is fuel-efficient or not needs to be determined based on the overall performance of a car. At the same time, whether the increase in thermal efficiency will affect the other performance of the engine, which will make the dynamic performance of the vehicle worse, is also a key. So, Bing Ge came to Changan Yidong's test drive with such questions.
The test drive of Yidong Blue Whale Edition is mainly divided into two parts, the field test drive and the actual road test drive. In the morning test drive, we can fully feel the changes in the power of this car
The cash 1.6L engine has a maximum power of 94kW, a peak torque of 161N·m, and a maximum torque speed of 4000-5000 revolutions. The 1.4T engine under the Blue Whale NE platform has a peak power of 116kW and a peak torque of 260N·m. The maximum torque can be burst at 1400 rpm. The difference between the front and back is not only reflected in the power and torque, but more importantly, the difference in the maximum torque speed! The transition of
from 4000-5000 to 1400 rpm means that the Yado Blue Whale version can reach the maximum torque output by almost stepping on the accelerator. Therefore, the moment I stepped on the accelerator pedal, the vehicle rushed forward very lightly, and I could feel a hint of pushing back during acceleration.
From the perspective of power performance, although the Yidong Blue Whale version is not comparable to some of the main sports models of the same level, it is already very good for the same price. Especially for young consumers, the dynamic performance of Yidong Blue Whale Edition is enough to let you find a trace of passion in the boring car life, which is actually enough.
control is very homely
Although the dynamic performance of the Yidong Blue Whale version is good, it seems almost meaningless in terms of handling. Combining the field test drive in the morning and the mountain road test drive in the afternoon, the handling performance of the Yidong Blue Whale version is actually average, which is mainly for the intense driving conditions.
As far as the dynamic feeling is concerned, the steering wheel adjustment of the Yidong Blue Whale version is light, even in high-speed road conditions. At the same time, when passing some relatively large bumpy roads, the vibration feedback from the chassis will be relatively large, but the filtering of some finely broken roads is still relatively thorough. In the state of high-speed cornering, the suspension support is soft and the body's roll will be larger, but the vehicle will still firmly grasp the ground, so there will be no lack of confidence.
Overall, in terms of dynamic performance, Yidong is still a main home model. Its handling adjustments are biased to provide passengers with a relaxing and comfortable driving experience, while the improvement of power is more to improve In order to improve the dynamic response of the vehicle, the driver can be more relaxed and confident in starting and overtaking actions.
Fuel consumption is not high, configuration is not low
During the test drive in the afternoon, we cleared the data of the vehicle before departure and turned off the air conditioner. After passing through different road conditions such as provincial roads and mountain roads, we finally got a display of 5.0L/100km Fuel consumption data. It should be noted that this is achieved without turning on the air conditioner, so combined with actual usage, it is estimated that its fuel consumption performance should be adjusted upwards by about 1L/100km.
But even so, we can also see the excellent fuel economy of this engine. In order to get this fuel consumption level, it is impossible to achieve only 40% thermal efficiency. The 35MPa high-pressure direct injection system, VDOP full variable displacement oil pump technology and the support of dual-outlet IEM technology, coupled with the efficient transmission efficiency of the dual-clutch gearbox, can achieve this result.
In addition, the Yidong Blue Whale version also has a pretty good configuration level. Such as ACC adaptive cruise system, right blind spot monitoring system, early warning auxiliary braking system and voice control system, are all very practical and can effectively improve safety configuration. In actual use, the voice control system’s recognition of voice and the system’s response speed are quite good, but the catch is that the camera’s resolution is low, which is slightly blurred when reversing the vehicle and turning on the right blind spot monitoring. It would be perfect to improve it a little bit.
