Changan CS75 PLUS has always been the star model of Changan Automobile, and the second-generation CS75PLUS was also put on sale at the end of February this year, and launched three 1.5T and three 2.0T models, with the official guidance price range of 12.49-15.49 million yuan. In fact, before Tencent Automobile experienced the second-generation CS75PLUS 2.0T version of the model, and this time with the opportunity of the #Harsh Challenge #Man-Machine Showdown - The Second Generation CS75PLUS Super Fuel Saving Challenge, on the one hand, experience the power performance of the 1.5T model, on the other hand, witness the real fuel consumption of the car.
The #Harsh Challenge #Man-Machine Showdown - The second generation CS75PLUS Super Fuel Saving Challenge, which can be said to be Changan Automobile's innovative fuel saving competition, for the first time adopted the challenge form of "real-time PK between humans and robots", mainly through the "indoor roller test" VS "outdoor road test" two major fuel consumption test methods to carry out the duel.
Among them, the "indoor roller test" can be understood as the fuel consumption run by Changan Automobile Robot to drive the second-generation CS75PLUS 1.5T version of the model, while the "outdoor road test" is the real road fuel consumption run by the media /user driving the second-generation CS75PLUS 1.5T version of the model, both of which are completed under the same road conditions. In addition, the organizer Changan Automobile also transparently displayed the entire process of the entire challenge in the form of real-time public live broadcast of the whole network, ensuring the fairness and authenticity of the competition process and the results of the competition.
The "outdoor road test team" composed of media/users, after filling the second-generation CS75PLUS 1.5T version of the model with gasoline, will put a seal on the fuel cover, and after checking the vehicle and tire pressure, start the vehicle and switch to ECO economic driving mode, subtotal mileage clearance, air conditioning to 20 ° C and two airflows, and finally set the car machine navigation to the only departure.
The "Indoor Roller Test Team" is prepared in Changan Global R&D Center, and through the chassis dynamometer to simulate the competition route and actual road conditions of the "Outdoor Road Test Team" 1:1, as well as carry out synchronous fuel consumption test.
The competition route is the round-trip route of "Chongqing Downtown - Qijiang Gujian Mountain - Chongqing Downtown", along the way will pass through the city road, inner ring expressway, G75 Highway, Gujian Mountain Scenic Area Mountain Road, etc., with a total length of about 170km, it can be said that this is a full road route that fits the actual driving scene of the user.
The models in this test drive are all second-generation CS75PLUS 1.5T models, equipped with Changan Blue Whale's new generation NE1.5T four-cylinder turbocharged engine, and matched with Aisin's 8-speed manual transmission. The engine has a maximum power of 138 kW (188 Ps) and a peak torque of 300 Nm, which is 10 Ps and 30 Nm higher than the first generation model.
The engine also adopts dual outlet integrated exhaust manifold, double scroll electronically controlled turbocharging and other technologies, which can effectively reduce turbo hysteresis, and there is also an original "AGILE Agile" air diversion type efficient ultra-clean combustion system, which can further reduce fuel consumption when meeting the emission requirements of China 6b.
Because we have test-driven the second-generation CS75PLUS 2.0T version of the model before, the high explosion and smoothness of the whole set of power are still fresh in my memory, and the driving quality of the chassis is obviously better than that of the first generation model, but after we experienced the 1.5T version of the model, the mature power matching and chassis tuning also continued to this model. Even in the fuel-efficient ECO economy mode, the vehicle from stationary to start is still very brisk, switching to Sport mode does not have the performance of about to "jump" like the 2.0T model, and in the subsequent initial acceleration process, the power connection is very smooth, and the throttle is also very heeled.
In the urban area will often encounter stop-and-go situations, this 1.5T + 8AT combination in the low torque performance is also good, the transmission can always give priority to maintain the smoothness, so this also makes the second generation CS75PLUS 1.5T model in the city road with ease. Even if it is an occasional sharp acceleration and line or overtaking, the power output is very powerful, and the transmission can quickly downshift to actively cooperate, which is really well matched.
In the high-speed road conditions, the performance of this 1.5T engine in the middle and rear section acceleration is more general, and there is no 2.0T version of the model's feeling of sufficient power reserves, even after switching to the Sport mode, the power response will become more positive, but the continuous acceleration is still limited, after all, it is limited by displacement, and the appeal of the 1.5T version of the model is also fuel-efficient, so it will not have much impact on ordinary home users.
The second-generation CS75PLUS 1.5T version of the test drive is equipped with the IACC full-speed intelligent cruise system, which is a set of L2-level driver assistance system, which can be opened by only one button in the left middle of the steering wheel when the lane line is clear and other conditions allow, which is very simple and convenient to use. During the experience, although the system does not force the vehicle to be kept in the middle of the lane, it is not only the control of the distance with the car, or the performance of acceleration and deceleration, even when passing through a large curvature curve.
Thanks to the silent accessory belt system used in the 1.5T engine, the silent chain, the dual-stage small stiffness design of the dual-mass flywheel and the damping spring, etc., the car appears quieter during acceleration. Even at high speed, there is no obvious engine noise, on the contrary, only part of the wind noise will pass into the car, and the communication of passengers in the car will have basically no impact. It can be said that the performance of the vehicle NVH also has a slight advantage in the same level.
The steering wheel provides 3 kinds of steering force adjustable, but the difference in feeling is not very large, and the overall feeling is light, which is also more conducive to female car owners. At the same time, the steering wheel direction is relatively clear, combined with the good tracking of the rear of the car, it is easier and safer when running the mountain road.
The chassis suspension is also a front McPherson type + rear multi-link independent suspension system, the adjustment style is more comfortable, and the size vibration and bumps of the road surface can be handled more appropriately, which maximizes the comfort of passengers, but when cornering at a higher speed, the support for the body is still slightly insufficient.
Test drive summary: When the second-generation CS75PLUS 2.0T model was test-driven before, the power performance of the 2.0T+8AT set brought us a surprise, and the driving quality of the whole vehicle was also significantly improved, but I did not expect that these advantages were also continued in the second-generation CS75PLUS 1.5T model, especially the adjustment of the starting and initial acceleration was very smooth and linear. Make the 1.5T model more adaptable to complex urban road conditions, although the explosive force in the middle and rear section of high-speed driving is not as good as 2.0T, but the 1.5T has better fuel economy than the 100 km fuel consumption (the minimum fuel consumption of 100 kilometers in this challenge is 6.8L), which is more important for ordinary consumers at the moment when oil prices are soaring.
And the #Harsh Challenge #Man-Machine Showdown - the second generation CS75PLUS Super Fuel Saving Challenge, finally won by the No. 9 car in the "outdoor road test team", running out of the real fuel consumption of 6.8L per 100 kilometers, compared with the 7.0L fuel consumption of the "Indoor Roller Test" robot team, with a slight advantage of 0.2L, it can be said that this is also the most real demonstration of the "1.5T Blue Whale Engine + Aisin 8AT" powertrain fuel-saving strength. In addition, in Changan Automobile's many "indoor roller tests", the robot has also achieved a minimum fuel consumption performance of 6.5L.
