Audi Quattro: Complete Guide on the 4WD System
The Audi quattro system is a unique all-wheel-drive technology that delivers remarkable traction and high performance in challenging conditions, not to mention the safety and peace of mind it provides.
The Italian word “quattro,” which translates as “four” in English, refers to the four driven wheels (4WD). But how does it actually work and what makes it so renowned? Below you will find detailed information on its technologies, its evolution over the years, and why it remains a favourite among drivers who demand the best in every condition, including winter driving under the harsh Quebec climate.
In summary
- The quattro system is an iconic Audi technology, delivering phenomenal grip and stability in every season.
- The quattro ultra optimizes energy efficiency with on-demand activation, without compromising traction.
- The e-quattro adapts this technology for electric models to provide an almost instantaneous response and enhanced performance.
- While cornering or on slippery roads, the quattro transmission offers superior control and an unmatched driving experience.
- Perfect for Quebec, it remains a benchmark for winter driving and safety on snow and ice.
What is the Audi Quattro System?
You probably already know that the Audi quattro system is an integral part of Audi’s DNA, having revolutionized performance levels with vehicles that provide drivers with outstanding grip even in challenging road conditions—such as those we experience during our harsh winters. But what exactly makes this system unique?
The story dates back nearly 50 years to 1977, when an Audi chassis engineer, Jörg Bensinger, observed a military all-terrain vehicle (specifically the German military Iltis) operating in difficult conditions. Suddenly, an idea struck him: what if a sedan could be equipped with a similar all-wheel drive system? After discussing it with his technical director, they decided to study this technology on a prototype, the Audi 80, the following year. Then, in 1980, the now-iconic quattro system made its debut at the Geneva Motor Show.
Here are some of the key factors responsible for its long-lasting and resounding success:
Variable Torque Distribution
To deliver power precisely where it is needed, torque is distributed variably between the front and rear wheels. In other words, the axle with the highest level of grip receives extra traction to maximize vehicle stability.
Torque Vectoring
With the Audi quattro system, torque is intelligently managed. When engaging in a turn, the torque acts by applying the brakes on the inside wheel, proactively redistributing power to the outside wheel. This not only facilitates easier cornering but also enhances manoeuvrability.
Rear Sports Differential
With the optional rear sports differential, power is also sent to the outer rear wheel during turns, similar to torque vectoring. This enables that wheel to rotate faster, allowing for maximum performance.
Differences Between the Quattro and Quattro Ultra Systems
Introduced for the first time on an Audi Q5 in 2018, the Audi quattro ultra system is an evolution of the standard quattro. It is, of course, also an all-wheel drive system, but with a significant advantage.
While the standard quattro system operates continuously, the quattro ultra operates on demand. This means that when full traction is not required, the quattro ultra uses its dual-clutch system to disengage the rear wheels, effectively operating as a two-wheel-drive system.
The result? You get the same exceptional traction in challenging conditions while maximizing energy efficiency when the system is not needed. Below are the details presented in table format:
Audi E-Quattro: The Quattro System for Electric Vehicles
The Audi quattro has also been adapted for the brand’s electric models. This Audi e-quattro system distributes the electric motors’ torque to the wheels in approximately 30 milliseconds. A true feat that provides you with remarkable control!
For certain performance models, such as the Audi e-tron S and e-tron GT, torque management—known as “e-torque vectoring”—allocates power from the rear axle to the wheel that needs it most, resulting in phenomenal and instantaneous traction, while also maximizing energy efficiency and, consequently, your vehicle’s range.
The Quattro System and Concrete Results in Quebec Weather Conditions
As you can see, the Audi all-wheel-drive system is extremely sophisticated and effective. If you would like to test it, do not hesitate to get in touch with your Audi West Island dealership in Montreal, near Pointe-Claire, Beaconsfield, and Sainte-Dorothée.
Audi Quattro Performance on Snow and Ice
The Audi quattro system performs well in every season, but it truly shines in winter. Every driver who has faced snowstorms or icy roads will confirm its effectiveness.
Maintenance Cost and Reliability of the Quattro Transmission
The reliability of the Audi all-wheel-drive system is proven. It is a durable system built on nearly 50 years of experience and has been refined over time. While maintenance can sometimes be perceived as expensive, it is important to remember that the manufacturer produces luxury vehicles. When compared to its direct competitors, these costs remain more than reasonable.
