Which is better, the MR481QA engine of the Liberty or the SQR477F engine of Chery's new Qiyun (launched on July 1, 08) with a displacement of 1.5?

Checked out and compiled the information as follows:

The parameters of the new Qiyun 1.5 are as follows:

Engine model SQR477F

Exhaust volume (l) 1.5

Power (Kw(ps)/rpm) 80(109)/6000

Maximum torque (N-m/rpm) 140/3000< /p>

Freelander 1.6 parameters:

Engine model MR481QA

Exhaust volume (l) 1.6

Power (Kw(ps)/ rpm) 78.7(107)/6000

Maximum torque (N-m/rpm) 137/5200

Working condition diagram:/che168/cardb/model_pic/1156930371_1630.jpg

From the above parameter, it can be seen that the 1.5 Chery SQR477F. Both in the maximum torque and maximum power are better than the 1.6 Geely MR481QA, because the data is not very informative so did not list the liter power and specific power, but I think the 1.5 Chery SQR477F liter power will be much greater than the 1.6 Geely MR481QA, the two cars are equal in weight, the same load under the power performance of the 1.5 Chery SQR477F will certainly be stronger than the Geely MR481QA.

From the working condition chart, we can see that the 1.5 Chery SQR477F is a double-peak chart, close to the maximum peak in the 2500 to 5000 rpm range, which ensures the acceleration of the dynamics, and at the same time is suitable for both driving and stopping in the city, and also suitable for running on the highway, the fuel consumption will be controlled relatively low; relatively speaking, the Geely MR481QA is only close to the peak after 4000 rpm, then the low fuel consumption will be controlled relatively low. In contrast, Geely MR481QA has to be close to the peak at 4000 rpm, so the low acceleration performance should not be pursued at all, and it will be more wasteful of fuel in the city, and it will be better to run on highway. So when it comes to fuel consumption, I personally feel that the 1.5 Chery SQR477F is about 1 to 1.5 fuel points less than the Geely MR481QA.

As for the quality of the vehicle, after all, the new Qiyun has not come out, there is no way to compare, but from the previous years Chery and Geely market sales, tend to Chery better.
