What does Quattro mean?

Quattro

It is full-time four-wheel drive, which can effectively distribute the engine's power to the four wheels at all times. A Torsen mechanical center differential ensures road grip from all four tires. Under normal driving conditions, the quattro system will distribute power to the front and rear wheels in a 50:50 ratio. In bad road conditions, the system can automatically adjust to 25:75 or 75:25. When the left and right wheels are in contact with different road conditions, EDL can prevent the wheel from slipping. One wheel is braked and excess power is transmitted to the other tire.

What does Audi quattro mean?

Quattro is Audi’s registered trademark for four-wheel drive technology.

Quattro is the focus of Audi's publicity, and it has outstanding performance. It is worth noting that the core technology of the four-wheel drive system cannot be completely and absolutely represented by the words Quattro and 4motion. Because Audi and Volkswagen brands, both owned by Volkswagen, share technology, the core technologies of the four-wheel drive systems of two different brands on some models may be the same.

Advantages and disadvantages of the Quattro system:

Quattro equipped with the Torsen differential system is characterized by excellent passability, road performance, active safety and response speed. Because it is a pure It distributes power mechanically, so it also has excellent stability that other systems cannot achieve.

Its disadvantages are that it has a larger mass and higher cost, and it can only be used in longitudinal engine models. Except for most Audi models, Audi's A3, TT, etc. use transverse engines, so they use the same differential system as most 4MOTION.

What does Audi’s quattro mean? What's the use? The benefits are there.

Audi's quattro means full-time four-wheel drive system.

Audi's quattro means full-time four-wheel drive system. quattro is a permanent four-wheel drive mode that maintains four-wheel drive under any circumstances. When cornering, the Torsen differential allows a certain speed difference between the front and rear axles, thereby avoiding the traditional four-wheel drive system. interference phenomenon.

Audi Quattro is a full-time four-wheel drive that takes into account both road performance and passing performance. It does not rely on any electronic equipment, and at the same time achieves these performance requirements through exquisite purely mechanical design, so Audi Quattro has extremely high response speed, which brings great benefits to highway driving.

Notes on Audi quattro:

Audi Quattro not only represents Audi’s full-time four-wheel drive technology, but also represents one of Audi’s cars, in which the lowercase “q” stands for full-time four-wheel drive. Wheel drive technology, the capital "Q" stands for Audi Quattro cars.

Audi Quattro is the first car equipped with quattro four-wheel drive system, so it is named after Quattro. Audi Quattro is developed on the basis of the RS5 model. The power system uses Audi's 2.5L 5-cylinder supercharged engine, which can output 408 horsepower and 480N.m.

What does Audi quattro mean?

Audi quattro refers to Audi's full-time four-wheel drive technology. Its core four-wheel drive technology is the Torsen center differential. This differential is a worm planetary gear structure and uses a purely mechanical working method without the need for Electronic systems intervene. Compared with other differentials, the Torsen center differential can adjust the torque distribution between the front and rear axles of the car in a more timely manner, allowing power to be output from the planetary gears to drive the front and rear axles.

The quattro full-time four-wheel drive technology can effectively prevent the car from skidding. When the car exits corners or skids quickly, the adhesion of the rear wheels will increase, and the quattro full-time four-wheel drive system will increase the speed of the car. More torque is distributed to the rear wheels, allowing the car to get out of trouble.

Advantages of full-time four-wheel drive

Full-time four-wheel drive is the transmission mode with the highest cornering limit on the road. It can allocate the best power to each wheel when the vehicle corners at high speed. driving force. Therefore, this technology is adopted by a large number of large-displacement cars that emphasize handling performance, and the main purpose of assembling them is to improve the effective driving force and cornering limit.

The structure of full-time four-wheel drive is relatively complex, the cost is high, and it takes up a relatively large space, so it is not suitable for assembly on lower-positioned or smaller models. At the same time, full-time four-wheel drive consumes power, and its transmission efficiency is lower than that of two-wheel drive. For models that value economy and have small engine power, full-time four-wheel drive is not suitable for assembly.

Under normal circumstances, the power ratio of the front and rear wheels of the full-time four-wheel drive system is 50:50. When encountering roads with different adhesion, the central differential will distribute the power in a certain proportion. After redistribution, since the system always maintains four-wheel drive and there is no step to switch to two-wheel drive, the full-time four-wheel drive model has better performance in terms of evasion and active safety performance.

What does quattro mean?

It means full-time four-wheel drive system. quattro is a full-time four-wheel drive mode that maintains four-wheel drive under any circumstances. When cornering, the Torsen differential allows a certain speed difference between the front and rear axles, thereby avoiding the traditional four-wheel drive system. interference phenomenon.

The working principle of quattro is as follows: Once there is a speed difference between the front and rear axles caused by external conditions, Torsen will automatically transfer most of the energy to the capable drive axle without loss. , automatically optimizing and distributing power to the four wheels. Thanks to the balanced distribution of axle loads, the driver has greater control over steering precision and agility without the need for torque steer assistance.

Four brakes ensure better braking effect, and the four drive wheels also achieve better acceleration and higher cornering stability.

Audi quattro full-time four-wheel drive is a systematic application of this basic physical principle. However, that's not all: depending on the driving situation and road surface, quattro permanent all-wheel drive also distributes drive power continuously between the front and rear axles. Especially on slippery roads, this means better traction and a safer ride, even when both drive wheels lose grip.

What does Audi’s quattro mean?

Refers to Audi's full-time four-wheel drive system.

Audi quattro refers to Audi's full-time four-wheel drive technology. Its core four-wheel drive technology is the Torsen center differential. This differential is a worm planetary gear structure and uses a purely mechanical working method without the need for Electronic systems intervene. Compared with other differentials, the Torsen center differential can adjust the torque distribution between the front and rear axles of the car in a more timely manner, allowing power to be output from the planetary gears to drive the front and rear axles.

The quattro full-time four-wheel drive technology can effectively prevent the car from skidding. When the car exits corners quickly or slips, the adhesion of the rear wheels will increase, and the quattro full-time four-wheel drive system will increase the speed of the car. More torque is distributed to the rear wheels, allowing the car to get out of trouble.

The Audi Quattro is manufactured based on the RS5 model, with length, width and height of 4.28m, 1.86m and 1.33m respectively, and a wheelbase of 2.6m. The power system comes from Audi's 2.5L five-cylinder supercharged engine, with output increased to 408 horsepower and 480N·m. The quattro concept car weighs 1,300kg, accelerates to 100 kilometers in 3.9 seconds, and has the advantage of ultra-low fuel consumption of 8.5 liters.

The Audi Quattro concept car uses an upgraded version of the quattro mechanical four-wheel drive system. The new differential has two new differential gears, and the power distribution can be wider. The ordinary front and rear power distribution is 40: 60. In extreme cases, a torque distribution of 15:85 or 70:30 can be achieved; since the rear wheel serves as the driving wheel, with the new limited-slip differential lock technology, all power can even be output to one side. on the tires.

Advantages and disadvantages of the Quattro system:

Quattro equipped with the Torsen differential system is characterized by excellent passability, road performance, active safety and response speed. Because it is a pure It distributes power mechanically, so it also has excellent stability that other systems cannot achieve.

Its disadvantages are that it has a larger mass and higher cost, and it can only be used in longitudinal engine models. Except for most Audi models, Audi's A3, TT, etc. use transverse engines, so they use the same differential system as most 4MOTION.
