What Is Audi Quattro and How Does It Work?

Audi is well known for its unique all-wheel drive technology, known as Quattro, which was initially utilised on rally vehicles before being introduced into mass production.

Audi’s Quattro all-wheel drive system, which was developed for rallying, is famous for its unmatched performance and cutting-edge engineering. It was groundbreaking when it debuted in the 1980s compared to competing products, transforming the vehicles that had it into road rally cars that were also great daily drivers.

The driver may confidently accelerate out of every bend because of Quattro’s amazing traction. To comprehend this, we’ll look at its history and several generations.

The History of Audi Quattro

Italian for “four,” Quattro was created in 1980 to offer Audi an advantage over rivals in rally racing. It was initially used to refer to Audi’s first all-wheel drive (AWD) rally car, but it is now used to refer to the AWD technology that is included in the majority of Audi cars.

Soon after its introduction, the moniker Audi Quattro became well-known as a result of the dominance of vehicles using this technology in rally competitions. Due of this, rally enthusiasts started referring to this period as “The Quattro Age.”

Audi’s cars weren’t as well-known when they were originally introduced as they are now. The business established a reputation as a premium automobile manufacturer that not only paid close attention to detail but also

All-Wheel Drive vs. Four-Wheel Drive

The words all-wheel drive (AWD) and four-wheel drive (4WD or 4×4) refer to two distinct methods of distributing a vehicle’s power to all four wheels, respectively.

The majority of the time, regular passenger cars have AWD, and sometimes you may choose it (you can toggle whether you want to have both axles driven or just one.)

With separate differential locks and occasionally a low-range transmission, 4WD is almost solely seen on trucks, SUVs, and heavy-duty vehicles, which makes them ideal off-road.

How Does Audi Quattro Operate?

The way Audi Quattro transfers power to the wheels plays a significant role in how it differs from many other AWD systems. It shifts power to the corners that require it most to enhance traction by using sensors to detect differences in wheel speed at each of the four corners.

While more recent Quattro cars that employ the CAN protocol rely on sensors and other technologies to do the same thing, early Quattro versions alone altered which wheel got torque via mechanical methods. Quattro makes use of a central differential, much like many other AWD systems.

In most driving situations, just one axle is motorised since most roads have adequate traction. Power will be distributed to the front and/or rear under more difficult circumstances. The traction control system in the automobile controls everything.

Variations in Audi Quattro

The first generation of Quattro, sometimes referred to as Gen 1, is regarded as the greatest among enthusiasts. The centre and rear differentials could be electrically locked in this generation, allowing power to be distributed equally to each wheel and giving the driver more control over how the automobile performed.

Quattro dominated the competition in the rally arena thanks to its outstanding performance, and in the years that followed, it was outlawed. All Audis were fitted with Gen 2 Quattro systems beginning in 1988, which included the Torsen centre differential. 80 percent of the engine’s power might now be transferred to either the front or rear axles rather than being divided 50/50.

The Torsen-based Quattro system’s central differential makes it simple to change which axle it delivers power to. The Haldex system, which is used in front-wheel drive Audi automobiles, can not function in this manner since it can typically only transfer up to 50% of the power to the rear axle. Although the Haldex system can perform the same fundamental tasks as the Torsen solution thanks to the addition of a rear differential, most fans do not believe it to be an authentic Audi Quattro.

Certain Quattro versions come with Sport differentials and other performance-improving accessories, enabling them to perform well on the track they were built for.

Quattro’s Legacy

From the ground up, Audi Quattro has shown that it has a place in both motorsport and on the road, where it enables driving fans to fulfil their aspirations of being a rally driver. Even other automakers have been influenced by it to design AWD vehicles with rally-inspired styling.

Audi will need to adjust as pollution laws get more strict, therefore it will be fascinating to watch how they do so. A series of all-electric vehicles from the firm have already started to be assembled. Even if cars like the Q8 E-Tron SUV have nothing technical in common with earlier gas-powered Quattro models, Quattro continues to play a significant role in Audi’s brand image.
