Audi S5: Does It Feature Four-Wheel Drive?

When considering a performance car that blends luxury, power, and sophisticated engineering, the Audi S5 frequently emerges as a top contender. With its sleek lines, potent engine options, and a reputation for refined dynamics, it's a vehicle that excites many a petrolhead. However, a common question that often arises, especially for those navigating the varied British weather, is about its drivetrain: does the Audi S5 have four-wheel drive?

The simple and resounding answer is yes, almost every Audi S5 model produced has been equipped with Audi's highly acclaimed Quattro permanent four-wheel drive system. This isn't just a minor feature; it's a fundamental pillar of the S5's identity and a core component of what makes it such a compelling driver's car. Quattro is far more than just a system for adverse weather; it’s a sophisticated piece of engineering designed to enhance performance, stability, and safety in virtually all driving scenarios.

Understanding Audi's Quattro System

Audi pioneered the permanent four-wheel drive system in passenger cars with the original Quattro in the early 1980s. Since then, it has become synonymous with the brand's performance and safety credentials. For the Audi S5, Quattro means that power is continuously distributed to all four wheels, rather than just two. This proactive distribution of torque significantly improves traction, grip, and stability, especially during acceleration, cornering, and in low-grip conditions such as rain, snow, or gravel.

The heart of the Quattro system in most S5 models is a mechanical self-locking centre differential. This ingenious component can instantly and seamlessly vary the torque distribution between the front and rear axles. Under normal driving conditions, the system typically maintains a slight rear-bias, often around 40:60 (front:rear) for a more engaging and balanced driving feel. However, if one axle begins to lose traction, the differential can rapidly redirect a much larger proportion of the power to the axle with more grip. For example, it can send up to 70% of the torque to the front wheels or up to 85% to the rear wheels, all within milliseconds and without the driver even noticing.

Later iterations and specific S5 models, particularly in the B9 generation, also feature the 'Quattro with ultra technology' on some engines. This system is designed to be more fuel-efficient. While it can operate as a permanent all-wheel-drive system, it can also decouple the rear axle when not needed, allowing the car to run in front-wheel drive for improved efficiency. However, it can re-engage the rear axle within a fraction of a second when more traction or dynamic performance is required, making the transition imperceptible to the driver. This intelligent system continually monitors driving dynamics, road surface conditions, and driver input to predict when four-wheel drive will be beneficial.

Why Quattro is More Than Just a Winter Feature

While Quattro excels in challenging weather, its benefits extend far beyond just getting you home safely in a blizzard. On dry tarmac, it contributes significantly to the S5's dynamic capabilities:

• Enhanced Traction: During hard acceleration, the ability to distribute power across four wheels dramatically reduces wheel spin, allowing the S5 to launch with incredible efficiency and grip. This translates to blistering 0-60 mph times.
• Superior Handling: Quattro helps the S5 to corner with impressive precision and stability. By intelligently distributing torque, it minimises understeer and oversteer, allowing the car to hug the road and maintain its line through bends, even at higher speeds.
• Increased Safety: The improved grip and stability provide a greater margin of safety, especially when unexpected road conditions arise or when evasive manoeuvres are necessary. The car feels more planted and predictable.
• Confident Driving: Knowing that the car is constantly optimising its grip instils a sense of confidence in the driver, allowing them to exploit the S5's performance potential more readily and safely.

Audi S5 Generations and Quattro Availability

Across its various generations, the Audi S5 has consistently relied on Quattro as a cornerstone of its performance package. Whether you're looking at a coupe, Sportback, or convertible, the presence of four-wheel drive is a defining characteristic.

B8/B8.5 Generation (2007-2016)

The original Audi S5 (B8 chassis) and its facelifted B8.5 counterpart prominently featured the Quattro system. The early V8-powered S5 Coupes, as well as the later V6 supercharged S5 models (including the Sportback and Cabriolet), all came with permanent Quattro as standard. This generation predominantly used the Torsen-based centre differential, known for its robust and purely mechanical operation.

B9 Generation (2017-Present)

With the introduction of the B9 generation, the S5 continued its commitment to four-wheel drive. These models, powered by a turbocharged V6 engine, also feature Quattro as standard. Depending on the specific engine and market, these S5s might utilise the self-locking centre differential or, in some cases, the 'Quattro with ultra technology' system, offering a blend of performance and enhanced efficiency.

It is exceptionally rare, if not non-existent, to find an S5 model sold new without Quattro in the UK market. The S5 is designed as a performance model, and Audi deems four-wheel drive essential to deliver the expected levels of grip, handling, and safety that S-badged cars demand.

Quattro AWD vs. Other Drivetrain Systems

To truly appreciate the advantages of Quattro, it's useful to compare it with other common drivetrain configurations:

As the table highlights, Quattro AWD in the S5 strikes an excellent balance, offering superior traction and handling without the significant compromises often associated with FWD or the potential for instability of RWD, especially for drivers who aren't seeking a purely track-focused experience.

Maintaining Your Quattro System

While the Quattro system is renowned for its robustness and reliability, like any sophisticated mechanical component, it benefits from proper maintenance. Owners of an Audi S5 should be aware of a few key considerations:

• Differential Fluid Changes: The various differentials (centre, front, and rear) contain lubricating fluid that can degrade over time and mileage. While not always specified as a frequent service item, changing these fluids periodically can contribute to the longevity and smooth operation of the Quattro system. Consult your owner's manual or an Audi specialist for recommended intervals.
• Tyre Management: It is crucial that all four tyres on a Quattro-equipped vehicle are of the same size, type, and, ideally, have very similar tread depths. Significant differences in tyre diameter can put undue stress on the differentials, leading to premature wear or even damage. This is why tyre rotations are also important for even wear.
• Professional Servicing: Any unusual noises, vibrations, or changes in handling characteristics should be investigated by a qualified Audi technician. They have the specialist tools and knowledge to diagnose and rectify any potential issues with the Quattro system.

Frequently Asked Questions About Audi S5 Quattro

Is Quattro always active in the S5?

For most Audi S5 models, particularly those with the self-locking centre differential, Quattro is a permanent system, meaning power is always being sent to all four wheels.
