Qinhuangdao Shougang Racing Valley is the world's first street racing track that shuttles between metallurgical industrial plant and FIA2 A2 certified track. At the same time, it is also a seemingly simple but challenging thing. This 3.8-kilometer track is characterized by high-speed corners and right-angle corners, which especially tests the performance of vehicles and the courage and skills of drivers. The main running methods are running outside and running inside, with full throttle straight, and a few corners are mainly slow in and fast out. Because it is a street racing track reconstructed from an industrial zone, the buffer zone and shoulder are not ideal, and it may be dangerous if you are not careful. So safety is the top priority of this track experience. This activity is divided into four parts: track experience, linear acceleration experience, pile-winding experience and road test drive.
Friends who have seen Fast4Word know that Audi TTRS on a certain tone is not only a frequent visitor to the 0-400-meter acceleration race, but also has won many championships. Linear acceleration seems simple, but there are many skills and stresses in it. We are experiencing 0-200m acceleration this time. This project is mainly based on RS5Sportback and RS5? Mainly Coupe models. The powerful Quattro full-time four-wheel drive system and chassis adjustment provide a guarantee for the stability of the car body. Porsche Panamera also has the same 2.9T? V6 twin-turbo engine +8AT gearbox provides powerful power reserve for vehicles.
Turn on the RS mode, shift to the S gear and press ESP to turn it off. The left foot accelerator pedal and brake pedal are trampled to death. RS5? Coupe will immediately enter the ejection mode, and the hiss from the default ejection speed of 3-4 thousand rpm and the jitter of the pointer when ECU "violently suppresses" the speed will make your blood boil in hearing and vision.
At the moment when the brake is released, the torque of 600 Nm is further amplified by the 8AT gearbox, and is preferentially distributed to the front and rear axles by the mechanical central differential of the crown gear at a ratio of 40:60. Under the blessing of Quattro four-wheel drive, the wheels showed no signs of slipping. At this time, RS5 is like a runaway wild horse. This constant acceleration produced a strong feeling of pushing my back, which even made me dizzy 1-2 seconds. After crossing the 200-meter landmark, I can still feel that the power has not been fully squeezed, and there seems to be a lot of room. With the appearance of the blue pile bucket, I subconsciously braked again and saved myself. It's no joke to accelerate 100 kilometers by 3.9 seconds (conservative result).
The snake-shaped pile mainly tests the driver's mastery of the rhythm and stability of the vehicle during driving, which depends on your subtle control of the steering force, throttle and brake pedal opening. In the meantime, you should not only keep your eyes on the front, control your route in and out of the corner, but also maintain a uniform power output, so that the center of gravity of the vehicle is as consistent as possible before and after, so as to complete the fastest action around the pile.
The model we experienced in this meeting is Audi S4. Compared with the high-performance model of RS5, although the power is not so fierce, it can move around the pile more flexibly with its light body. In terms of power, 3.0T? V6 twin-turbo engine, 354 HP, 500 Nm. With the support of 8AT gearbox and quattro four-wheel drive system, S4 can keep continuous power output when winding piles. In the process of continuous pile winding, S4 locomotive has positive response and excellent controllability, which gives the driver some confidence. The independent suspension of the front and rear five links also provides good support when the vehicle turns continuously, so that the wheels can stick to the ground tightly.
In the corner experience and the whole track experience, RS5? When Coupe turns at a high speed, the vehicle is firmly confined to a safe range. Even if there is understeer, the electronic auxiliary system of the driving computer will save you instantly. Especially after the RS mode is turned on, its steering becomes more accurate. When turning continuously, as long as you follow the route of the red pile bucket and brake in time after passing the blue pile bucket, you can easily pass.
Quattro four-wheel drive system equipped with powerful RS5 adopts the basic power distribution of 40 before and 60 after. When the adhesion changes, the power distribution can be adjusted between 70: 30 and 15: 85. Shall we test drive RS5 this time? Coupe? The sports suspension system is also selected, which can minimize the roll and vibration of the vehicle, make great contributions to cornering and provide sufficient confidence for drivers.
There is a restless heart under the low-key appearance, road test RS4? radical
The road test is mainly to experience the comfort and versatility of Audi RS4 as a daily driving. The distance of about 46 kilometers includes urban roads, rural roads and mountain roads. Starting from Shougang Racing Valley, after passing through the congested urban area, driving in comfortable mode is not much different from ordinary cars. Specially adjusted suspension can be fully qualified for daily use, and excellent NVH can also appropriately alleviate driving fatigue. Soon after leaving the city, the motorcade began to drive into the mountainous area, where there were many detours and steep slopes. For this practical performance car, vehicle handling, suspension support, braking and acceleration performance can also be perfectly handled. With the deepening of the mountainous area, there are fewer and fewer vehicles on the road. Switching to dynamic mode, the whole chassis becomes more tough, and the four shock absorbers are adjusted in real time through DRC dynamic drive system, and the control is improved in essence. At the same time, the beast that cannot be made by force has been awakened, and the rich exhaust sound is still so sweet. The strong push-back feeling of stepping on the accelerator comes again, thanks to the powerful power combination of 2.9T+8AT (450 HP in 4.1s, 600 Nm, 0- 100km/h acceleration), which is the correct attitude to drive it.
When the vehicle speed drops below 60km/h, the vehicle switches to the comfort mode, and the beast seems to be smart at once, and the sound of sports exhaust disappears immediately. The engine speed is reduced from 8AT gearbox to 1900r/min, and the comprehensive fuel consumption per 100km is about 10L. Excellent fuel economy once again proves the extraordinary features of Audi's automotive technology.
This track experience trip made me interested in Audi RS5 car series, Audi RS? 4? Have a deeper understanding of Avant and Audi S4 products. They have both a low-key side and a flamboyant capital, and can also complete long-distance travel like a family car. The power combination of 2.9T+8AT, supplemented by Quattro full-time four-wheel drive and a large number of electronic auxiliary systems, makes driving easier and more interesting. I have to say, when Audi looked up, you really lost.
