A report from the car gourd circle
What is hidden , This time , I've got a taste of ！
Mairuibao from SAIC GM Chevrolet XL（2.0T）, Recently 1′54″168 One lap performance , Refreshed “ Zhejiang tournament ”20 The fastest lap speed of mass-produced models within 10000 .
How fast is this ？ There is no comparison , No harm ！
This achievement not only surpasses “ app ” Led the g 03+ And golf MK7 GTI, And with the million class high-performance car BMW M3 The gap is only 1 In seconds . As for Toyota 86、 subaru BRZ、 Juliet 280...... Left far behind by it .
a 20 10000 class joint venture medium-sized vehicles , There was such an amazing performance on the track , Michael sharp treasure XL Enough for people to call “ I X”. But there are rational people who are skeptical , After all, in the eyes of everyone , Michael sharp treasure XL The size of the 、 power , It doesn't look like a sharp tool on the track , So he asserted ： It must have been passive .
Go further , Michael sharp treasure XL You have to take
Undeniable? , Many manufacturers , In order to get a good result on the track , Will more or less get hands on the test vehicle . Especially when there are “ Green hell ” The new North track , Many vehicles with brush circles have been specially adjusted according to the characteristics of new North track .
however , Test vehicles in the official lap speed list of Zhejiang International Circuit , They are all in the original state , That is what we commonly call a vegetarian car , Without special modification and adjustment . otherwise , The test vehicle will not be published on the list , This is also to reflect fair competition .
Mairuibao in this test XL（2.0T）, There is no doubt that it is also in the original state , you are here 4S What does the store see , This mairuibao participating in the test XL That is, what kind of .
In order to reflect fair competition , Another key factor is people , That is, the drivers involved in the test .
The official circle speed list published by Zhejiang race , The test drivers are relatively fixed , Mainly by Zhang Zhendong 、 Ye Hongli 、 Three drivers from rocaro Cairo served as . And this time mairuibao XL Test of , It was driven by roccairo . so to speak , Relatively fixed test drivers , It must also reflect the fairness of the test as much as possible .
But one element is equally important , That's the weather , But this is clearly uncertain .
generally speaking , A temperature of more than ten degrees can make the vehicle in a better working condition . however , Michael sharp treasure XL Test day , The temperature has reached 33℃. Hot weather for vehicles , It will not only reduce engine efficiency , For braking systems 、 Cooling system 、 Tire grip will have a great impact .
Michael sharp treasure XL Under the premise of adverse weather conditions , Force a crowd of small steel guns and performance cars , Can achieve such excellent results , It has to be admirable .
It seems impossible , Michael sharp treasure XL How to do it ？
near 5 Meters of conductor 、 only 2.0T The engine of , Michael sharp treasure XL Won the Zhejiang race 20 The fastest mass production car in wannei is honored , It's incredible . But how did it do it ？ We might as well look at the essence through the phenomenon , Maybe you can find the answer .
in fact , In terms of absolute dynamic performance , Michael sharp treasure XL In fact, it has inherent advantages .
Cash mairuibao XL Replaced a large-scale train from the general system LSY 2.0T Variable cylinder engine , Whether in Buick Regal GS、 Lacrosse , Still in Cadillac CT5、CT6 On , You can see the trace of this engine .
In terms of Technology , The machine LSY 2.0T The engine uses such as an integrated exhaust manifold 、 Electronic turbine waste relief valve 、 Double vortex single tube and other technologies . The use of these technologies , Mainly to improve efficiency , In addition, the engine also has intelligent cylinder changing technology , This is obviously for energy conservation .
But fortunately, , This engine still has more advantages than other joint ventures 2.0T Dynamic parameters of the engine ,237 The maximum horsepower and 350Nm Maximum torque of . This also makes mairuibao XL Whether in the initial stage , Or in the middle of the acceleration phase , Can bring strong explosive force .
However , near C Dimensions of administrative vehicles , It's Mai Ruibao XL Must face the reality .
But fortunately , Michael sharp treasure XL The engineer , Seems to have found a way to overcome this “ be congenitally deficient ” Methods , That's lightweight . After all , There is a saying in the car circle ,“ Ma Lizheng 10 horse , It's better to reduce the vehicle weight 10 Jin ”. therefore , Lighter body under the same power , It will inevitably bring a greater thrust weight ratio .
Michael sharp treasure XL 2.0T The vehicle weight of this model is 1525kg, This is compared to the previous generation of smaller models （ Michael sharp treasure ）, It's lighter . More power , With a lighter body , Michael sharp treasure XL Not only the power comes more directly , And the fuel consumption performance is better than that of the previous generation .
Of course , Michael sharp treasure XL Lightweight , It's not what you think “ Simple match ”, But technological progress . This is mainly reflected in the engine 、 chassis 、 Lightweight of body structure .
First at the engine level , Michael sharp treasure XL Our engine uses many composite materials , At the same time, the integrated design also greatly reduces its weight . More Than This , Engine cylinder 、 cylinder head 、 The cam covers are made of aluminum alloy , This has also become the key to the overall lightweight of the engine .
Secondly, in terms of chassis , Michael sharp treasure XL Aluminum alloy parts are also widely used , For example, steering knuckle 、 Suspension control arm 、 Body support and hydraulic bushing, etc . in addition , front 、 The rear anti roll bar also adopts a hollow structural design . so to speak , Michael sharp treasure XL The lightweight of the chassis is the ultimate .
It plays an important role in vehicle lightweight , It's Mai Ruibao XL The car body is made of many high-strength steels , And applied to A/B/C column 、 Sill, floor beam, etc , Not only has it made a great contribution to lightweight , It also further improves the safety in collision .
With the decrease of the mass on and off the spring , The benefit is a leap in handling performance . Lighter overall mass , There will be no greater inertia , Michael sharp treasure XL It's like a sprinter who has left all kinds of baggage , Better dynamic response and better follow-up are brought about by light loading , Speak straight and white , That's more flexible .
such , Michael sharp treasure XL（2.0T） Get excellent results , It's a matter of course .
A good seedling , I'm afraid no one knows the goods ？
Michael sharp treasure XL Control of 、 power , Obviously, it's too good to say . With the excellent performance of the brush ring , Michael sharp treasure XL Also brushed a wave of sense of existence on the Internet .
however , Michael sharp treasure XL It seems to be a “ I recommend you buy it , Really, I don't buy ” The models , And the biggest obstacle , I'm afraid it's brand power . in fact , In the eyes of many people , Michael sharp treasure XL Our strength is obvious to all , In the elk test of a media not long ago , made 83.3km/h The result of passing .
What's the concept ？
BYD Han, which was similar in size before EV, In the elk test 80km/h The result of passing , And was praised by a crowd of melon eaters . so , The elk passed the test and was able to reach 80km/h It's already pretty good , But Mai Ruibao with better results XL, It doesn't seem to be known by more people , The reason is that the attention is not high .
Undeniable? , Consumer choice 20 10000 class medium-sized car , Often the brands concerned are in Japanese or German , The focus on the beauty department basically rests on the Buick brand . As the flagship car of SAIC GM Chevrolet , Michael sharp treasure XL It seems to be a forgotten model .
Now , Even Mai Ruibao XL There are considerable discounts at the terminal , It is only in the market 4000 Sales of more than one set , Compared with the sales of other mainstream joint venture medium-sized vehicles , It's still a long way from . Especially Toyota, which has almost no preferential terminal 、 Honda's midsize car sales , Also dump Mai Ruibao XL A large part .
in fact , On the comprehensive strength of products , Michael sharp treasure XL It's not the best in its class , But definitely not the worst . such as , Huge space 、 The shape of the sedan 、 Rich configuration , And the perfect mechanical quality we talked about , These are enough for Mai Ruibao XL Bonus points .
What's more? , The transmission that was once used to make complaints about the slot , Now it is also replaced with more reliable 、 Better ride 9AT. As for the quality of the engine , For now , There are no negative problems . What's more? , This one has a high probability of being installed in the three joint venture brands of SAIC GM LSY The engine , If problems continue , That's not lifting a brick and hitting yourself in the foot ！
In that case , Michael sharp treasure XL There is no fatal short board , Even the whole is quite balanced , But the sales volume is not satisfactory , The only explanation is , Lack of Chinese people's understanding of Chevrolet brand . But this high probability can be attributed to , Differences in domestic positioning between Chevrolet and Buick brands .
however , It doesn't hurt .
As a racing driver Louis Chevrolet Personally founded brand , The track gene always flows in the blood of Chevrolet brand . In the long years of more than 100 years , Chevrolet brand relies on the pursuit of speed , Won countless trophies 、 Won numerous awards .
Today, , Michael sharp treasure XL Use the brush ring again , It proves the original intention of Chevrolet brand that has never changed .
To borrow Dante's famous saying ,“ Go your own way , Let's go .”
Have a mairuibao XL, Let yourself enjoy it , Don't care about other people's views .
