The test drive Weilang do in Yantai, Shandong, is not a common test drive city car manufacturers to choose here, but here is very story.
Here I Shandong sea intestines, birds shellfish, fish and so on seafood with a wonderful story.
Closer to home, although the speed of laboratory before we have a test drive this car, but I still want to simply say that, because this car has given me a deeper impression.
this time I drive a RONNIE 1.3T + CVT powertrain, because of the job, and I Buick models have had relatively deep contact Buick for a new car can be considered more familiar with, but sets of 1.3T Weilang actually I kind of feel both familiar and unfamiliar, feel like old friends not seen for a long time after a new boyfriend, the people are a little bit different look.
familiar is its texture chassis, new chassis, as always, let Weilang people impeccable, leapfrog is not too much to say, I was driving in the car most of the city will go to intentionally or unintentionally, to avoid bad roads and manhole covers, driving Weilang, then I can safely pressure in the past, I do not know it give me and my passengers to bring too much discomfort.
and strange it is its new powertrain, this 1.3T + CVT powertrain is first mounted on Weilang.
Although the powertrain Weilang change from the previous four-cylinder 1.5T + DCT now this has become a three-cylinder 1.3T plus CVT,Such a view, not only reducing the emissions RONNIE also reduced the number of cylinders, which could not help worrying: Will power as before? First, take a look at the performance data of the new car.
From the data point of view, this new powertrain compared to the old 1.5T set of difference is not significant.
[123 ] then the actual driving performance in how it?
First, Let me talk about it NVH performance three-cylinder, three-cylinder should in fact we are most concerned first this. The triplex can say is currently on the market with a better level of performance three-cylinder models, though turn around in 2000 when there will be some slight jitter transfer to the steering wheel, but these are so small jitter does not affect driving experience, will not be felt by the passengers to get on board. This new car’s NVH and I used to open the GL6 compared to a lot better, it can be said Weilang the overall performance of this triplex is very “four-cylinder”,
[ 123]
Another point is commendable, new Weilang been greatly improved in smoothness of power output, the turbine involved very smooth, not there’s a sudden power increase, so does not give the driver a vehicle to flee feeling very good control, we can say that the accelerator pedal learning cost is very low, it also allows RONNIE does not become an everyday driving tired of the car.
The most important thing is, this CVT will not give me the feeling before CVT open when the accelerator when the light kind of deep listening to a sound, watching the tachometer pointer shot up, but the situation is that the car does not go, this CVT will simulate the shift, but also in the case of rapid accelerationThere are more direct power output, compared to the control power delay most CVT is much better.
# [ 123] matches
in the power unit, the power good output performance of the engine and gearbox not only need to look at each product itself is not good enough, how about also very important match between the engine and gearbox, it’s like two very good people, if there is no good understanding between them that their cooperation will be less effective.
and this is the new RONNIE This new powertrain highlights.
In order to solve the problem of power matching, this new 1.3T Weilang of + CVT the beginning of the development of the power unit from the vehicle, the engine and transmission of the synchronous development proceeds, the output of the engine to the transmission characteristics of key parameters team, the team then performed gear transmission, and a shift ratio in accordance with these characteristics curve optimal design to ensure vehicle performance while meeting the needs of always allow the engine to work at optimal efficiency region to form the best power output, bringing smooth and efficient driving experience.
[123 ] then the power units should match well what does?
we can see in the official data,By developing positively synchronized, this means holding the torque power output of the engine and gearbox can be consistent under different conditions:
When the engine more focus adjustment the accuracy of the output torque to meet the higher demand for transmission control, to achieve most of the conditions, the output torque 100Nm, the positive and negative error value is only 5Nm; output torque 100Nm above, positive and negative control error values 5 percentage in order to achieve industry-leading standards.
is also considered at high altitude and high temperature environment impact engine performance and transmission control, the engine output torque is calculated and the actual output torque of the transmission to match.

[ 123] engine description:

[ 123] the CVT gearbox introduced: and with this 1.3T engine synchronization, forward the development of CVT gearbox equipped with general Motors the world’s leading innovation-driven technology, the reason for this CVT can have a very good dynamic response, using a steel chain transmission system has a very big help, it also the first use of the transverse structural steel chain precursor of formula CVT transmission.
chain double rotation section rotates the compact, the chain bending, rotation form rolling friction between the compact, power loss and wear reduced to a minimum, with the chain of smaller working radius, to achieve class-leading range greater ratio 7.01. While its maximum speed ratio is 2.623, so the car better start acceleration; minimum ratio 0.374, to achieve better fuel economy. 
The CVT while still using the three long-stroke damper, smart bis acting pump, stacked heat exchangers, active oil level management to achieve better power performance, fuel economy and comfort. 
this power
of the new WeilangUnit through a very rigorous durability testing, while SAIC-GM (Dongyue) powertrain manufacturing base of high-level BIQ Level4 certified to ensure eight years, 160,000 km long warranty manufacturers promise, but also to ensure that the the vehicle can have a more reliable guarantee of product quality and consistency.
The new RONNIE not only inherited Buick has always been excellent ride texture, in terms of fuel consumption has also been a lot of progress, the Ministry hundred kilometers only 5.5 liters, if fuel consumption is the only reason you do not choose American car, then you should not refuse this new Weilang.
