"No need to slam on the brakes, no need to slow down, it's an all-oil bend!" Don't worry about the limits of the vehicle! "The coach sitting in the co-pilot was very dissatisfied with my subconscious oil collection action. He said, "Track driving, racing against the clock, stepping on the accelerator who will, the real thing about going down the track is the brakes, who steps well, steps less." ”
Under the coach's instructions, I drove faster and faster, a few laps down, and I was in full swing.
Not long ago, Changan UNI-T 2.0T held a test drive activity at the Xiamen International Circuit. A total of two experience links are set up, one is the pile array, and the other is the track.
Readers may find the pile array looking small, and the speed of the vehicle is not particularly fast, which is not as enjoyable as the track.
In fact, the pile array allows you to quickly find the logic of vehicle tuning within a limited range.
If the vehicle tuning is more mobile, the grip of the vehicle, the chassis in dynamics, the performance of the turn is better.
In addition, whether the engine tuning is biased towards low torque, whether the power release is sufficient at low speed, whether the gearbox is active or procrastinating, can be tested in the pile array.
Off the track, you can test the limits of a car's straight-line acceleration and cornering.
In addition, how responsive a car's power is, it can also be tested on the track.
I really enjoy this type of test drive.
In addition to test driving the vehicle, I also interviewed the Changan Automotive Performance Engineer with a small book and dug up some materials other than the press release.
UNI-T 2.0T is not only powerful, but also has a lower center of mass of the whole vehicle
For the average person, UNI-T 1.5T is fun enough. This SUV has a maximum output of 138 kW, 300 Nm, and accelerates from 0-100 km/h in 7.6 seconds. The maximum output of the UNI-T 2.0T is 171 kW, 390 Nm, and the acceleration of 0-100 km/h is 6.8 seconds, which is more powerful.
More than that, the engineer told me that compared to the UNI-T 1.5T, the UNI-T 2.0T vehicle centroid is reduced by 40mm!
"Compared with the second-generation CS55PLUS, the UNI-T 1.5T has lowered the center of mass by about 55mm to 640mm by lowering the chassis and getting on the car. The powertrain of the UNI-T 2.0T was changed from 1.5T+7DCT to 2.0T+8AT, which is inherently low in centroid. In addition, we upgraded the chassis on the basis of UNI-T 1.5T, pressed the suspension stroke down, and combined, the vehicle center of mass was reduced by 40mm, the height was reduced by 20mm, and the centrifugal force and cornering roll were reduced by 4.5%. ”
The benefit of a reduced centroid is increased stability, the same speed down cornering, and less roll.
Like F1 racing cars can enter the corner with a beautiful posture, first of all, low center of mass, wide wheelbase, and secondly, the body rigidity is high, and what has little to do with power. The acceleration after the corner depends on the response and power.
In addition to low center of mass, the wide-track, long-wheelbase body design leads to better stability (UNI-T front track 1600mm, rear track 1610mm, wheelbase 2710mm).
This setting is a bit like a go-kart, the go-kart is not fast, but it is very enjoyable to drive, because the go-kart has a low center of mass, and the four wheels expand outwards, the better the handling.
Coupled with the 20-inch German horse brand MaxContact MC6 tire, it has greatly improved the working conditions such as rapid acceleration and high-speed cornering.
Realistically, UNI-T is doing really well. I was on the Xiamen International Circuit, a fast Mercedes,
It seems to be integrated with the car, falling into a state of self-forgetfulness.
The same is the Blue Whale 2.0T engine, but the tuning is different
Engineers told me that although the UNI-T 2.0T and UNI-K are also equipped with Blue Whale's new generation D series 2.0T engine + Aisin 8-speed automatic transmission, the tuning of the two is not the same.
"UNI-T 2.0T is not the same as UNI-K positioning, and the adjustment logic is also different. UNI-K is a medium-sized SUV that pursues smoothness, and UNI-T 2.0T pursues responsiveness and acceleration on the basis of smoothness. Therefore, the UNI-T 2.0T is more aggressive to open, and the gear change speed is particularly fast. ”
The engineer added that comparing the 2.0T engine code-named K20C on honda Guandao, the UNI-T 2.0T engine is full of power.
The UNI-T 2.0T can output 350 Nm of torque at 1500r/min and peak torque at 1900r/min, giving people the feeling of being very aggressive and surging power on call.
The Guandao 2.0T only reached peak torque at 2250r/min, and the power came very gently, eloquently, but the speed range was long and the staying power was sufficient.
"Looking at the engine data is only one aspect, but also depends on the tuning idea, if you are very interested in power output, UNI-T 2.0T is absolutely suitable." The engineer said.
{ Write at last }
Since the birth of the automotive industry, extreme performance has been the industry's highest pursuit and has been driving the progress of this industry.
In the past few years, Chinese brands have made great progress, manufacturing thresholds, design thresholds, quality thresholds, and even technology research and development thresholds, have been crossed one by one, and the only thing left is the performance threshold.
Now that manufacturers have chartered the racing track, letting car owners and media test drive is the best way to test performance.
Behind this move, it reflects a kind of self-confidence.
The stylish look, the Blue Whale 2.0T engine, the 8AT gearbox, the 390 Nm torque, the ejection start, the 6.8 seconds to break the hundred, these hardcore data outline the UNI-T 2.0T.
The price of UNI-T 2.0T is also not high, and a total of 4 models have been launched, with a price range of 137,900-14.99 million yuan. It can be regarded as a rare performance car in the same class and price, and it can also be said to be the most cost-effective model.
