Some time ago, Harbin was popular all over the Internet, and the northern country under the cold wind became the most lively place for a while. And we drove the Audi Q7 all the way north this time, but we didn't come to join in the fun. **Although the main street and Sophia Cathedral are beautiful, the purpose of this trip is to pick up the ice at the Songhua River at -30 °C. Here, we will drive the Audi Q7 to the extreme ice pulling challenge. With the Audi Q7 as the tractor, it weighs about 8 on the ice8 tons of ice traveled 100 meters. See how Audi's proud quattro all-wheel drive system can perform under such a tough test.
The frozen north of the country, with a low temperature of almost -30 °C, makes the city of Harbin unique. The three-foot deep Songhua River, facing the bright sun, reflects the city's vista. Every breath of air exhaled condenses into frost and mist, embellishing a fantasy mood. And in the midst of this wonderful scene, the Audi Q7 is ready for battle. Driving on ice is undoubtedly a difficult thing for a family car. Basic physics knowledge tells us that the ultra-low coefficient of friction on the ice surface will inevitably have a huge reduction in the release of kinetic energy from the wheels. In the process of driving, if you are not careful, it is even more likely to slip. And 88 tons of ice, equivalent to the weight of 100 adult males. If you want to drag it for 100 meters under such conditions, you can't do it by relying on "recklessness" alone. It can be said that even engineering vehicles with excellent load capacity may not be able to complete this challenge.
As a concrete masterpiece of the Audi brand spirit, the Audi Q7 is not only a mid-to-large SUV that emphasizes comfort, but also an industrial artwork that skillfully integrates sportiness, functionality, high-tech and luxury quality, and is a model of new luxury. The Audi Q7 dares to face such an extreme ice pulling challenge that goes beyond the ordinary driving situation. Its confidence is the accumulation of Audi's century-old technological innovation and its insistence on quality. The Audi Q7 is a load-bearing body structure equipped with 3The 0T turbocharged engine, mated to an 8AT gearbox, accelerates from 0 to 100 km h in just 5 hours9s。Its appearance, power, luxury equipment and excellent handling are its obvious excellence. What's more, the quattro all-wheel drive system is the ultimate in this challenge.
At the end of the orderly on-site preparation, huge ice cubes were stacked and placed in place. In the low temperature environment, the ice will freeze after a short period of contact with the ice surface above the river, which will make the challenge more difficult again. Vehicle inspections, towing device inspections, ice inspections, everything is ready to go. The Audi Q7 is ready to go, with huge blocks of ice behind it, and it's hard to imagine what it takes to drag it 100 meters. The initial stage of the whole challenge process is undoubtedly the most difficult part. The ability to exert initial momentum on the huge ice pile is the key to success or failure.
The Audi Q7 starts to exert force, and in order to drive smoothly to prevent skidding, the initial speed of the Audi Q7 is not fast. The wheels rolled slowly, the tow rope belt straightened, and the challenge scene became a tug-of-war. The ice piles are in place, and the Audi Q7 silently exerts force forward, and in the momentary static confrontation, the huge wrestling attracts everyone's minds. One second, two seconds, three seconds, in fact, it didn't take too long, someone shouted - "moved". The wheels of the Audi Q7 undergo a slight swing and roll forward at a slight angle. The huge pile of ice finally let go of its hold and began to slide forward with the car at a slight rate. This result is undoubtedly due to the Audi Q7's powerful quattro all-wheel drive system, a purely mechanical** differential, which provides the body with a real-time super grip.
In the blink of an eye, the Audi Q7 was driving too fast, and its powerful power performance was perfectly unleashed, dragging the ice pile to maintain a steady speed, and driving forward in a steady attitude. To know that dragging 88 tons of heavy ice driving on the ice, stability is definitely the first appeal. If there is a slippage, or if there is a shift in direction, you can imagine the catastrophic consequences of the inertia created by the huge ice pile. It's obviously freezing ice, but it has a feeling of walking on thin ice. As the finish line finally approached, the Audi Q7 dragged the ice piles and continued to drive forward with perfect steady, and finally successfully completed the challenge.
Audi with advanced and complete technical system, to create the Audi Q7 such a powerful kinetic warrior, the whole system is equipped with pure mechanical Torsen ** differential quattro full-time four-wheel drive system, providing real-time super grip, in the ice and snow such a low adhesion road environment, when the system detects wheel slip, it will zero delay the vehicle front and rear axle power ratio between 70:30 and 15:85 free allocation. The advantage of the Torsen differential is that it simply relies on the complex mechanical gear set meshing for power distribution, which can automatically sense the speed difference and carry out limited slip feedback, and the response is very timely. In addition, the Audi Q7 includes seven driving modes, which can be switched to snow and ice mode, and can also be used to bring more active real-time grip through the electronic limited slip system. And the car is equipped with 3.The 0T engine bursts out with 250kW and 500N·m strong power, which is also the basic guarantee for its comprehensive dynamic performance.
The outstanding performance of the Audi Q7 is the result of Audi's excellent tradition of vehicle dynamics. It seems that the Audi brand has an inherently strong sporty DNA. Whether it's the quattro technology being so powerful that it was banned from touring car racing by the FIA, or the 13 podium finishes at Le Mans 18 times, or the Dakar Rally victory with the Audi e-tron just in January this year, it's enough to demonstrate the power of the Audi brand. High performance and controllability are in the DNA of every Audi car.
When it comes to sporty performance, how can you bypass Audi's famous quattro all-wheel drive technology? The quattro first made its debut at the Geneva Motor Show in 1980. In 1986, Audi AG replaced the first generation of artificially locked** differentials with a Torsen differential. In 2005, Audi developed a rotating gear that distributes the basic dynamic forces in an asymmetrical way. What's more, Audi has been pushing the boundaries of quattro technology. More than 8 million Audi vehicles have been equipped with quattro technology, which is one of the cornerstones of the company's development and is even more viable with new technologies.
An extreme ice pull challenge in the frozen snow country has made the Audi Q7 once again the uncrowned king of power performance. Based on Audi's brand spirit of continuous exploration of technological innovation, the Audi Q7 has undoubtedly a strong product vitality. The challenge of pulling ice, just 100 meters but like a hundred years of steps, shines with the technological innovation and accumulation of Audi's 100 years of development. Audi's enterprising spirit of innovation and daring to challenge is also perfectly inherited by the Audi Q7 and leads this era.
