Original by Gou Ge, the power chapter of the new generation Tiggo 7 test drive report

There is a lot to talk about the new generation of Tiggo 7, so we will talk about it in different aspects. The first and most important thing to talk about is the power system and power performance, which will involve the gearbox. The following will The CVT25 gearbox used in Taiwan's new generation Tiggo 7 will be discussed separately.

The power system of the new generation Tiggo 7 is very talkative. It is divided into two series, 1.6T and 1.5T. Since the price of 1.6T is relatively high, it is estimated that the manufacturer has not much sales of the 1.6T Tiggo 7. It is hoped that consumers will mainly buy 1.5T due to price issues, so we also focus on the powertrain of 1.5T plus CVT25. ?I am really familiar with this 1.5T engine. ?I am the owner of a 2018 Tiggo 8. The engine of my car is actually the same engine as the one used in the Tiggo 7. ?This is a 1.5T electronic injection engine rather than direct injection in the cylinder, which is very important.

The 1.5T engine of the new Tiger VII is an improved version of the 1.5T EFI engine on the Tiger VIII. It has been upgraded from National V to National VI emissions, and the engine peak torque has been increased from 210 Nm to 230 Nm. Meter, to put it simply, it is more powerful. Others generally upgrade from National V to National VI and the power drops. Chery’s National V upgrade to National VI also increases the torque by 20%, which is awesome. ?Nowadays, the mainstream of engines is to pursue direct injection in the cylinder. It is true that direct injection in the cylinder is more powerful. However, relatively speaking, EFI also has its own advantages. EFI is more durable, can be rougher in maintenance, and slightly worse in use. The engine oil is fine, and the requirements for gasoline are also low. For my 1.5T Tiger Eight, I basically always add the cheapest 92 at a small gas station, and there is no problem. However, the engine with direct injection in the cylinder is definitely a bit more delicate. Under certain circumstances, if dirty gasoline is added, the engine may have a malfunction light. ?Another important premise is that Chery’s 1.5T electronic injection engine is actually very powerful and can be said to be sufficient. The Tiger Eight is larger and heavier than the Tiger VII. The 1.5T engine is already capable and even feels a little overpowered. The smaller and stronger Tiger VII has no problem. ?Therefore, if I were asked to choose, I would choose the 1.5T Tiger 7 instead of the 1.6T. ?The new generation Tiggo 7 test drive this time is a 1.5T plus CVT model. This is also expected. Obviously, Chery will focus on selling the 1.5TCVT model this time. ?Before the test drive, I had certain expectations about the power of this car, because this powertrain has been used in the Arrizo GX model before and has very good power performance.

When I first test drove the 1.5TCVT Arrizo GX, I was really amazed by the power performance of this car. The power was so powerful and the acceleration felt so good. . ?The start is clean and crisp, completely unlike a CVT model, there is no delay in power, and the throttle is very accurate and responsive. ?Accelerate with just a tap of the accelerator without any delay. ?As much as you step on the accelerator, you get as much power as you need. ?As soon as the oil on the big foot floor is removed, the power immediately surges, as shown in the figure of a wild horse running wild, and the power is hearty. ?It’s really a near-perfect power performance.

I once had a description of the power performance of the 1.5TCVT Arrizo GX. I thought it explained the problem very well, and it was also wonderful and proud. ?Driving a 1.5TCVT GX feels like wielding a bloody machete to kill people in the game, Three Kingdoms. You can step on it as you like with your right foot. A big foot on the accelerator will give you ferocious power, and a big foot on the brake will do the same. There is a good braking effect immediately, and it really feels like doing whatever you want.

In addition, there is a short story about this powered Arrizo GX, a true story. ?A Suzhou car enthusiast, who owns an Arrizo GX model with a 1.5TCVT, encountered an Audi A4 on the road to challenge him. He opened the window and raised his middle finger. The model was a 2.0T model with an unknown model year. The car owner couldn't stand his bad temper, so the two cars drove fast, reaching a maximum speed of 170. At each traffic light, the Audi stepped on the accelerator and jumped out first, and then the GX caught up. The same process was repeated at the next traffic light. Finally, the Audi gave up. . ?Therefore, I am quite looking forward to the combined power performance of this 1.5T plus CVT25 high-torque CVT gearbox. Of course, due to the high expectations, the actual test drive effect was a little disappointing.

?First try starting, the power and throttle feel are exactly as expected, the power response is very fast, the start is very light and fast, the throttle feels very good, especially the heel, the old CVT transmission There is a very obvious power delay in the engine. You have to start slowly and open it. Otherwise, if you step on the accelerator too much, it will not have strong power. Instead, the engine will roar and the speed will be too high, and the car will not move. ?Taking it all together, the power performance in the initial stage is exactly as expected, which is very good. ?Afterwards, I stopped and stopped on urban roads, and tested from starting to accelerating to a speed of about 60 kilometers per hour in normal driving conditions. The power performance basically met expectations. The speed increased very briskly, and the power was still available at any time, with the accelerator and foot.

Then enter the highway section. ?The first is to increase the speed with all the floor oil. At this time, the power of the new Tiger Seven does not have the hearty feeling of Arrizo GX. Although the speed is faster, it feels a little boring compared to the GX. The speed increase is not as good as mine As violent as expected. ?So if the default score of Arrizo GX’s speed-increasing ability is 90 points, I think the speed-increasing ability of the new Tiger 7 can be given a score of 80 points. This may be because my expectations are too high. ?Later I thought carefully about this issue. ?If the new Tiger Seven is compared with the GX, first of all, it will be slightly heavier. Therefore, with the same power, the speed will be slower. Secondly, the tire width of the GX is narrower than that of the new Tiger VII. Under the same power, the wider the tire width, the greater the friction, and the corresponding speed-increasing effect will be worse. In addition, the new Tiger Seven is an SUV, and its body height is much higher than that of a car like the GX. A taller body will cause greater wind resistance. The impact of this wind resistance should be more obvious when the vehicle speed exceeds 60. .

So under the premise that the power system is exactly the same, it is reasonable that the new Tiger 7, which has a taller body and greater wind resistance, wider tires and greater friction, and is heavier, is not as fast as the GX. of. ?At the same time, this also answers another question we have, why Chery has always insisted on matching the Tiggo 8 with a dual-clutch gearbox instead of a CVT gearbox. There is only one reason, and that is power performance. ?Judging from the power performance of the new Tiger 7, in order to obtain the ideal speed-up effect, the size and weight of the New Tiger 7 are the upper limit of this 1.5T plus CVT25 powertrain. If the larger and heavier Tiggo 8 matches With this set of power and power, there will be a certain gap from the ideal effect. So I personally think that there will be no Tiggo 8 with CVT25 in the future.

On the highway, apart from the fact that the speed-increasing effect of the floor oil from 0 to 100 is a little worse than expected, I am actually satisfied with the power performance of this new Tiger 7. The power is still available on demand without delay. Even if the vehicle speed exceeds 120, there is still good power response. ?In addition, this power system also shows another advantage, which is the innate advantage of the CVT gearbox, low speed. This gearbox is a CVT continuously variable transmission, simulating nine gears. Basically, this new Tiger 7 has the same gear. The engine speed in lower gear is the same as that of Arrizo GX. When the ninth gear is 120, the engine speed is around 2100 rpm. When cruising at a constant speed of 120, the engine is relatively quiet. After all, the lower the engine speed, the lower the engine noise. will be correspondingly lower.

There is also a small surprise, because it is a CVT gearbox. Normally, the steel belt may slip when the floor oil is accelerated, but I listened carefully to this new Tiger 7, and the floor There is no sound of the steel belt slipping when the oil is accelerated. ?Finally, I took the new Tiger Seven to the Haohan Slope, which I use most, to test its climbing power. There were two of me and a friend in the car. We started using the ECO mode and stopped at the bottom of the slope. Starting at 0 speed and climbing with oil on the floor, the power performance is strong and the climb is easy. Moreover, because there are some gravel on the road, halfway through the road, the tires slip and spin due to too much power and insufficient grip. However, the car is basically under control.

Theoretically, the ECO mode has such performance, and the sports mode is more relaxed and does not need to be tested, but I still tried the sports mode. ?In the same driving style, the new Tiger Seven behaves more violently in the sports mode, and the car's tire grip is not enough to cause slipping throughout the entire process. Because of the lack of grip, the climbing performance is not much different from that in the ECO mode. ?To summarize, the new Tiger Seven has a very good climbing effect, and the ECO mode can basically handle all common slopes.

Finally summarize the whole article.

?The start is easy, pleasant and light, there is no delay in power, and the throttle and foot are easy to open. ?The power in urban transportation is very satisfactory, and there is basically no difference between it and Arrizo GX. ?Under high-speed acceleration with full floor oil, the power performance is slightly lower than my expectation, which can be rated as good. It is a little far behind Chery's excellent speed-increasing models. I think it is caused by the tire width, vehicle weight and wind resistance. However, at the same time, It still has top-notch speed-increasing capabilities among SUVs in this class.
