[car home] Professional evaluation] After experiencing UNI-V at the venue in February this year, not long ago, we got the commercial version of the car with the road formalities, and conducted a comprehensive AH-100 test again.
(|) With its excellent face value performance, the market performance is indeed very hot, but the improvement of product strength is also one of the reasons for its concern. existThe change in design has won the recognition of more young consumers. Not only that, but also great progress has been made in driving texture. of course，In today’s test session, we also found some problems. Please read on for the detailed report.
Power system
The test vehicle is equipped with a 1.5T turbocharged engine with a maximum power of 188 HP (138kW)/5,500rpm and a maximum torque of 300 Nm/1,500-4,000rpm.The transmission part is matched with a 7-speed wet dual-clutch gearbox. It can be seen from the pictures that the layout design in the engine room is very regular, and the front tower top is equipped with a balance tie rod.
Dynamic experience, this time our test vehicle has legal procedures on the road, so we will focus on talking about the feelings of driving on the road. First of all, the power reserve is really sufficient, in the general highway.Driving, there is no feeling of output procrastination at all, and the dynamic response in the middle and front sections is very positive. When the turbine stepped in, it was still a little abrupt and unfamiliar.The feeling of pushing back is fierce, and the outbreak of torque is very sudden.
There is no problem with the power continuity in the middle and rear sections. We have traveled more than 200km on mountain roads, and the engine can provide excellent power output performance in the full speed range. In addition, although our machineThe test car has no variable exhaust valve system, but it still has good exhaust sound in the original factory state, which makes the driving atmosphere more passionate.
There are not too many problems in the overall performance of the gearbox. The response under daily driving conditions belongs to a category of comparative sports, and the ride comfort performance is worthy of recognition.The timing of shifting paddles is relatively fast, but the speed of shifting gears in manual mode is somewhat slow, which is not as refreshing as that in automatic mode.
When it comes to daily driving, the gearbox shows a very smart side in terms of overall logic, which can provide positive even in normal mode.Up-and-down gear feedback makes driving feel more brisk.In addition, this gearbox has ejection mode, specific use tutorial and operation mode, and detailed function introduction is given in the central control big screen.
◇ There is a setback in accelerating the test.
Due to the vehicle test process, the problem of power interruption occurs repeatedly, and the performance fluctuates greatly, so it is impossible to complete 10 accelerated tests continuously.UNI-V didn’t get effective test results in the end.To this end, we went to find another new car to verify whether it was a case. However, after the actual measurement, it was found that this problem also appeared in the new car. (Please see the video for details)

Changan UNI-V 1.5T DCTThe gearbox has ejection mode, which will help to speed up the test results, but problems also follow.According to the operation mode of the manual, make sure that the water temperature and oil temperature of the vehicle are in working condition, close the ESC body stability system and start the ejection mode.
Step on the brake and throttle to the end, and control the speed at 1900rpm. Release the brake and start to accelerate, and the front wheel instantly breaks through the grip. With the rapid increase of the rotating speed, the power of the gearbox will suddenly be interrupted after the first gear is upgraded to the second gear (see the video for details). The specific performance has a feeling similar to clutch slipping.(In the case of power interruption, test continuously for 10 times, and accelerate the performance at 0-100km/h, and stabilize it at about 9-10 seconds.)
After communicating with the manufacturer’s engineer, it is known that the gearbox of Changan UNI-V 1.5T DCT has a set of protection program called (No Shift), which will start to intervene when it is detected that the wheel is seriously slipping, and limit the continuous release of power, thus leading to the situation of no acceleration.
In any case, such a setting did have a significant impact on accelerated testing, and the official explanation also acknowledged the existence of this problem, only explaining that it was due to the protection mechanism. For consumers, when it is necessary to turn off the ESC stability control system and have a performance experience, I am afraid that there will be a very bad experience if the power is interrupted. However, we still hope to correct this problem and give a better experience of acceleration performance.

Test around piles
According to the test around the pile, the suspension shows a relatively balanced side in the face of rapid center of gravity transfer, and the integrity of the chassis is very good.Can provide relatively sharp dynamic feedback. However, the initial reaction speed of the steering system is not direct enough, which will give the driver a large central virtual position.Operation feeling. However, the following performance of the rear of the car is a positive category, and the overall performance in the pile-winding link is worthy of recognition.

Fuel consumption test
Fuel consumption test, turn on the air conditioning system, the mileage is 107km, the average speed is 31km/h, the fuel consumption is 7.68 liters, and finally the result is 7.2L/100km.
In terms of economic evaluation, the advantages of warranty and selling price are obvious, and the final score exceeds the average. The score of environmental protection is also close to the average score, and the final score is 8.4.
