On the evening of February 4, 2022, brilliant fireworks scattered over the "Bird's Nest", and Beijing, as the "City of The Two Olympics", once again became the focus of the world's attention; with ice and snow as the medium, China is destined to make the world stunning again. At the opening feast, did you ever recall the crowds and grandeur of the opening ceremony of the 2008 Olympic Games? Furthermore, it was found that the number of performers in this opening was greatly reduced, but the shock was not reduced that year.
Yes, in 2008, the motherland showed the world the power of humanity; this time, the motherland showed the world the "hard-core" scientific and technological power. In the future, technology is the king, and in the context of this scientific and technological rejuvenation, the "era of national ice and snow sports". The huge car circle, I am afraid that only Audi dares to float out a sentence, "This is my home of ice and snow."
In 1977, Audi engineers discovered that the four-wheel drive system had amazing handling performance on ice and snow roads, and then devolved the technology to the civilian field, and Audi quattro technology was born in ice and snow. This time, I pulled Li Xiang up and returned to their ice and snow home with two different personalities, trying to explore the limits of Audi's quattro technology.
Quattro technology is more than "stable"
In the process of this in-depth experience, Li Xiang, as a new generation of professional racers, said a particularly interesting sentence: "The 'sex' word of performance cars should actually have two explanations, one is performance, and the other is personality."
Yes, any performance car has a soul, and the protagonist of this time, the Audi RS5, is a 'violent gentleman', it will not ask you too much, nor will it irritate you with its not so good temper, RS is more willing to impress you with a more balanced, more stable feature.
The new Audi RS5 is equipped with a 2.9TFSI V6 twin-turbo engine with a maximum power of 331 kW and a peak torque of up to 600 N.m, which is generally very difficult to control in vehicles with this power parameter. But the RS5 is equipped with the pinnacle of Audi quattro technology development - the quattro full-time four-wheel drive system with a mechanical central differential, the system distributes the driving force to the front and rear axles according to the default ratio of 40:60 when the vehicle is running normally, but when the vehicle skids, more driving torque is automatically distributed to the axle with better traction, and the distribution range is between 70:30 and 15:85. In other words, Audi quattro technology will ensure that the vehicle's dynamic response is at its best at all times. It is precisely because of the blessing of quattro technology that this car still has a fairly stable curve performance in low temperature and low adhesion ice and snow fields.
Vehicle dynamic driving, "stable" is an advantage, but as a performance car, accurate handling is the basis. Audi quattro technology, which enables zero delay distribution of torque, transfers the vehicle's torque from the skidding axle to the adhesion side. The additional four-wheel steering system also further enhances the vehicle's flexibility and stability in corners. When we try to turn or accelerate on corners, most of the vehicle's torque is transmitted to the outer wheels, pushing the car into corners. When drifting or pendulum in the bends of ice and snow pavement, quattro technology can effectively prevent oversteering or understeering, and maximize the control of "shadow".
Play to the fun, Li Xiang with my ring drift, pendulum 8 words, quattro technology support, the vehicle's steady and accurate control performance made him praise, he sighed: "The track race mainly relies on the driver's technology, and audi RS5 has a quattro technology full-time four-wheel drive system, itself is like a battle-hardened professional driver, driving it can make ordinary people can also find the feeling of being a driver." ”
Quattro technology is more than just "quasi"
The reason why Audi quattro technology can last for a long time, in addition to the technology is "hard", its strong compatibility and malleability are indispensable, quattro technology is stable and accurate in the performance car, and in the SUV model, it reflects a completely different personality.
The new Audi Q7 55 TFSI is equipped with a powertrain composed of a 3.0T V6 engine and a 48V light hybrid system, with a maximum power of 340PS, and as a medium and large SUV, it accelerates from 0 to 100km/h in only 5.9 seconds. During my deep test drive, the power of the vehicle was hardly hystered, and in addition to the powerful engine power and the help of the light mix system, the mechanical differential of the Audi quattro contributed to it. Otherwise, in this kind of slippery ice and snow field, even if there is a lot of horsepower and abundant torque, if you can't release the power to the ground to the maximum extent, isn't it still "a punch in the air"? The Audi quattro technology can quickly capture the grip of the vehicle's individual wheelsets, and seamlessly distribute intelligently, always releasing the vehicle's power to the maximum extent to the attachment point, and avoiding the vehicle slipping or loss of control to the greatest extent.
Secondly, the quattro technology also infinitely amplifies the passability and certain ability to get out of the SUV model, the Audi Q7 front and rear axle wheels are open differentials, and the inter-wheel limited slip relies on electronic assistance. In the test drive process, whether it is a shell crater or a unilateral bridge, the vehicle's quattro technology four-wheel drive system can cope with it freely, the moment the vehicle enters the pit, the quattro system detects that the wheelset has lost power, and the "0 delay" distributes the power to the end of the wheelset with grip, so as to quickly get out of trouble. Although the difficulty of the venue is not large, under the cover of ice and snow, the calm "energy" of Q7 when it is out of trouble cannot be imitated by the general model.
On the whole, the Q7 gives me a very special feeling, because although the Q7 is large, it is more like a sports car with a relatively high sitting posture, without the rigidity of the traditional medium and large SUV, and the vehicle also has a good ability to pass. I'm also the first to use words like "smart and direct" to describe a medium-sized SUV.
Steady and precise, swift and fierce, this is the impression that Audi quattro technology has left us in the snow and ice. Being able to further amplify and sublimate the characteristics of different models, so that they have two personalities under one technology, this is the essence of quattro technology.
Audi quattro technology has undergone more than 40 years and three generations of change, changing the understanding of current consumer needs, and what has not changed is the obsession and belief in vehicles to get out of difficulties and improve handling performance under extreme road conditions. Whether it is the traditional mechanical quattro technology, or the quattro ultra, or the e-quattro, the four-wheel drive system can only be divided into two categories, quattro and others. And in the era when technology is king in the future, quattro technology will also accompany Audi models and continue to gallop in the home of the ice and snow it has created!
