Recently, with the changes in the international situation, the domestic gasoline price has risen repeatedly, even the price of 92 # gasoline per liter is approaching the 9 yuan mark, people's car costs have increased sharply, in the past, a tank of oil was filled for 300 yuan, and now 400 pieces are more than that.
As a result, consumers are paying more and more attention to fuel economy when choosing a car. Changan Automobile, which has always been known for its fuel savings, also did a second-generation CS75PLUS "man-machine duel" fuel saving race at this special node, and both the process and the result are very interesting.
▍Fuel consumption per 100 kilometers is only 6.8L
The biggest highlight of this game is the use of the form of "real-time PK of man-machine fuel consumption", that is, the PK fuel consumption of people and machines, through the actual road driving to see who consumes less gasoline and lower fuel consumption.
The specific operation is to drive the second-generation CS75PLUS in the "same road conditions" environment through the "indoor roller test field" machine group and the "outdoor road test field" personnel vehicle group for real-time PK.
Of course, in order to make the indoor and outdoor road conditions as consistent as possible, Changan Automobile specially used a "vehicle treadmill" to simulate the actual road environment during the race, and moved the chassis dynamometer into the indoor roller test field.
This machine can not only simulate the actual road conditions, such as speed, torque or on-board control mode, but also provide wind resistance through the built-in motor and wind tunnel, and restore the outdoor driving conditions as much as 1:1 indoors, so that the "man-machine duel" conditions are as fair and just as possible.
The outdoor road has selected a challenging route of "Chongqing Downtown - Qijiang Gujian Mountain - Chongqing Downtown", covering a total of 170 kilometers, covering the common road conditions in the daily driving of cities, highways, mountainous areas and other users, in order to fully demonstrate the technical level of the participants and the fuel saving and performance strength of the second-generation CS75PLUS.
Finally, after a day of competition, in this man-machine PK race, the "09" car group in the second-generation CS75PLUS outdoor pavement 9-vehicle group measured the lowest average fuel consumption of 100 kilometers, only 6.8L, and the automatic driving robot handed over the average fuel consumption of 7L per 100 kilometers.
It has to be said that relying on the Blue Whale power system, Changan Automobile's performance in fuel consumption is indeed very "low-key", and it has taken a "fuel-saving" reassurance pill for users who intend to buy a car.
▍"1.5T Blue Whale Engine + Aisin 8AT" is the key to victory
Technological breakthroughs, reflected in the application level, are often to benefit users. Through analysis, we know that the reason why the second-generation CS75PLUS is so fuel-efficient is mainly because it is equipped with a "1.5T Blue Whale Engine + Aisin 8AT" powertrain.
First look at this Aisin 8-speed manual transmission ——
We know that BMW, Volvo, and Lexus also use the Aisin 8AT, but different car brands have their own different names; on the other hand, they are slightly different in technology, including hydraulic torque converters, friction pad materials and quantities, but the core internal structure of the transmission is basically the same.
Of course, the Aisin 8AT equipped with the second-generation CS75PLUS is on the same platform as the same series of transmissions of luxury brands, with strong reliability, excellent smoothness, smooth and comfortable multi-gear switching, and through fast and accurate oil pressure control, the overall response to shifting can be increased by 40%, and the response to downshifting is faster when overtaking.
The control ability of power transmission is also an important indicator of a gearbox, this Aisin 8AT has a fast, accurate and intelligent control capability, can match a variety of driving modes, as well as idle start-stop control, idle neutral gear intelligent control, dynamic torque control, slip control, intelligent uphill and downhill control, etc., well adapted to the second generation of CS75PLUS a variety of driving conditions.
More importantly, with the help of this transmission, the fuel economy of the second-generation CS75PLUS has been improved, and the balance of strong power and low fuel consumption has been achieved, which is very top-notch in its class.
Look at this 1.5T Blue Whale engine -
It can be said that Changan Automobile Blue Whale series engine is a performance benchmark and technical business card in the field of automobile power in China, and the advantages are very obvious. Since its release in June 2019, it has received recognition and affirmation from many users.
On the second-generation CS75PLUS, the Aisin 8AT is a blue whale new generation NE1.5T high-pressure direct injection engine. Its maximum power is 188 hp, with a peak torque of 300 Nm, which is 10 hp higher than the previous model, and the peak torque is increased by 35 Nm. A steady stream of powerful power, is kept silky smoothly by Aisin 8AT.
Here is a technical point, a key pain point of the small displacement turbine engine is the hysteresis of the turbine, and the Blue Whale NE1.5T engine adopts advanced technologies such as dual outlet integrated exhaust manifold and double vortex electronic control turbocharging, which effectively reduces the turbo hysteresis, and can output peak torque at 1250rpm, low-end torque is super strong, even in many joint venture brands is also a first-line level.
In fact, the power system performance of Changan CS75PLUS has always been very good, and the data of the Blue Whale NE1.5T engine is already the top existence in the domestic camp. In actual driving, the initial acceleration of the vehicle is very brisk, the engine responds to the throttle in time, there is no delay in starting, the power output is also very smooth when accelerating in the middle section, and to what extent the foot is stepped on, the engine gives the corresponding degree of power, the body posture when entering the corner, and the power output when exiting the corner are relatively calm.
In addition, the suspension of the second-generation CS75PLUS 1.5T model is the front McPherson independent suspension, the rear multi-link independent suspension, which is consistent with the 2.0T model, the filter for road bumps is in place, the steering wheel is good, and the operation is light, even female drivers can be handy.
▍Technology is the highlight
Not only taking into account power and fuel consumption, but also in terms of the intelligent technology valued by users, the performance of the second-generation CS75PLUS can also be remarkable.
In fact, the second generation of CS75PLUS has buried intelligent technology in various scenes from the user's exit, after getting on the bus, driving, and getting off the car, and all the driver has to do is to feel this high-tech trip.
For example, when you are about to go out, the intelligent cloud control assistant on the second-generation CS75PLUS can turn on the air conditioner for the user through the mobile phone, adjust the temperature in the car, open the seat heating, make the seat warm and comfortable, start the air purification, the air in the car is renewed, and unlock the door in advance.
After getting on the car, when the user sits in the driver's seat, the Face ID face recognition function automatically identifies the owner's identity and learns the driving habits, so as to further adjust the steering wheel, seat position, and vehicle settings. Of course, you only need to lightly press the brakes and the vehicle can start. When the user focuses on driving, the intelligent W-HUD can capture the driver's gaze and display driving information in a comfortable position of view, which is more special.
When holding the steering wheel, Wutong Car Federation TINNOVE has become a highlight, under the command of intelligent voice, the vehicle can open the navigation, play music, control the sunroof, window opening and closing, etc., as well as the volcano car entertainment ecosystem, car vibrato, headlines, watermelon video, understand the car emperor and other rich entertainment APP to add color to the trip.
If you encounter congestion during commuting, after opening the IACC full-speed segment intelligent cruise function, you can realize intelligent car following, intelligent cruise driving in the lane, and sweep away the traffic jam and boredom. When the driver is tired and distracted, the fatigue monitoring and early warning will immediately remind the owner to concentrate and try to ensure safety through voice warning, music refreshment, call and other ways.
If the car is driven into a dead end, a dilemma, the practicality of the second-generation CS75PLUS on the trail reversing is reflected, the vehicle can be reversed according to the trajectory to solve the problem; narrow parking space, the car can go in, but people can not come out, how to do? With the APA5.0+ remote-controlled valet parking system, you can stand outside the car and remotely control the vehicle to park, go straight in and out. Of course, if the environment of the parking lot is too complicated, the high-definition 540 ° panoramic image system is also a great weapon, which can make the situation around the vehicle clear at a glance and avoid rubbing.
Write at the end:
At a time when Chinese people are becoming more and more culturally confident, China's first-line brands have also ushered in an explosive period. In the first month of listing, it won the champion of fuel SUV sales, and the second-generation CS75PLUS has become a star product in the market segment with multi-dimensional advantages such as "Blue Whale New Generation Engine + Whole Series Aisin 8AT" and excellent intelligent technology. With the increasing oil price today, the fuel economy advantage of the 1.5T Blue Whale engine is becoming increasingly prominent, becoming a representative of strong power and high energy saving, and the market potential is huge, which is also the future that the second generation CS75PLUS can expect.
