Audi RS6 2009 Review

As a high-performance wagon, the Audi RS6 has long been a representative of “hiding power under a low profile,” and the 2009 RS6 (C6 generation) takes this contrast to the extreme. In the Malaysian market, the audience for high-performance wagons is niche, but for enthusiasts who demand both everyday practicality and track-level power, the 2009 RS6 remains an indispensable choice to this day. This time, we got our hands on a well-maintained 2009 RS6 Avant. The core purpose is to verify whether, 15 years later, it can still meet the demands of performance car enthusiasts—after all, its legendary 5.0-liter V10 twin-turbocharged engine is still a topic of passionate discussion among car fans.

The exterior of the 2009 RS6 retains the understated style of the Audi family at that time, with an overall silhouette not much different from the standard A6 Avant, but its identity as a performance car is hidden in the details. The front end features the RS series' exclusive honeycomb grille, surrounded by glossy black trim. The headlights on either side are iconic xenon projectors from that era. Below, the bumper has larger air intakes to cool the twin-turbos and braking system. The lines on the sides of the body are smooth, and the standard wagon profile ensures practicality, while the 20-inch five-spoke Y-shaped alloy wheels paired with red brake calipers clearly reveal its performance attributes. The wheel arches are slightly flared, and the side skirts come with small diffusers, creating a visually lower stance. The rear design is relatively restrained, with the only performance hints being the dual oval exhaust pipes on one side and the small spoiler on the trunk lid—a "subtle yet sharp-edge" design approach that was a hallmark of the RS series at the time and highly appealing to enthusiasts.

Opening the door, the interior layout is largely the same as the standard A6 Avant, but there’s a noticeable upgrade in materials and features. The dashboard is covered with a large area of Alcantara fabric, and the steering wheel is a special three-spoke RS version. It’s thick and comes with paddle shifters, and the buttons on the left side can directly control the driving modes. Although the center display screen isn’t very large, it supports navigation and Bluetooth connectivity, and the physical buttons below are neatly organized for easy and intuitive operation. The seats are sporty bucket seats with excellent bolstering; the lumbar and thigh supports can be manually adjusted. The leather upholstery is stitched with the RS logo, and sitting in them provides a noticeable difference compared to regular family cars. In terms of space, the 2009 RS6 Avant has a wheelbase of 2,849 mm, and when the front seats are adjusted to a suitable position, there’s still about two fists' worth of legroom in the rear, with ample headroom as well. The trunk offers a standard volume of 565 liters, which can be expanded to 1,660 liters by folding down the rear seats—perfectly suitable for daily errands or long road trips. Notably, the rear also includes independent air conditioning vents and power outlets, offering practicality on par with family cars.

The highlight of the 2009 RS6 lies in its powertrain. It is equipped with a 5.0-liter V10 twin-turbocharged engine delivering a maximum power output of 580 horsepower and a peak torque of 650 Nm, paired with a 6-speed Tiptronic automatic transmission. During actual driving, the power output in normal mode is relatively mild. The throttle response isn’t overly aggressive, and the gear shifts are smooth enough that one may even forget it’s a performance car while commuting daily. However, switch to sport mode, and the car's character transforms instantly—the throttle becomes exceptionally sensitive, and even a light touch unleashes a significant push-back sensation. The whistle of the turbo spooling is distinctly audible, and the 0-100 km/h acceleration takes just 4.6 seconds (official figure), which ranked among the top-level performance cars of its time. The transmission also performs intelligently; in sport mode, shifts are noticeably quicker, with almost no delay in paddle responses, and downshifts come with automatic rev-matching for an exhilarating driving experience. In terms of handling, the RS6 features adaptive air suspension. In normal mode, the suspension is soft enough to absorb most road imperfections, while in sport mode, the suspension stiffens, effectively reducing body roll and providing excellent support when cornering, giving the driver great confidence. The steering wheel precision is excellent, with minimal slack, and it clearly conveys road information. However, due to the nearly 2-ton weight of the vehicle, some inertia can be felt during quick lane changes—after all, it is still fundamentally a wagon.

We specifically tested its fuel consumption performance. In urban road congestion conditions, the fuel consumption is about 18-20 liters per 100 kilometers; during highway cruising, it can drop to around 12 liters. For a 5.0-liter V10 twin-turbo engine, this result is within expectations. As for noise control, the wind and tire noise at high speeds are not particularly significant, but the engine's roar remains constantly perceptible — for performance car enthusiasts, this is actually a kind of enjoyment. The comfort of the seats is also worth mentioning. Although they are sports bucket seats, long drives do not feel tiring, and the lumbar support effectively alleviates fatigue.

In summary, the biggest advantage of the 2009 RS6 Avant lies in its "all-roundedness": it not only offers ultimate performance brought by 580 horsepower but also provides the practicality of a station wagon, balancing daily commuting and track fun. Compared to its contemporaneous competitors, such as the BMW M5 Touring, the RS6 holds an edge in power figures, and Audi's quattro all-wheel-drive system gives it better stability on slippery roads. However, its weaknesses are also obvious, such as high fuel consumption and significantly more expensive maintenance costs compared to regular family cars.

The 2009 RS6 is ideal for those who need a practical station wagon for daily commutes and carrying luggage while also pursuing extreme power — individuals who are not satisfied with the blandness of ordinary family cars and are unwilling to sacrifice practicality. For this group of people, the combination of "low-profile performance + practical space" offered by the 2009 RS6 Avant is still an irreplaceable choice.

Overall, the 2009 Audi RS6 Avant is an "all-rounder" performance car. It doesn't have an overly flashy appearance but hides a V10 engine that can ignite your passion, while also meeting all the needs of a family car. Fifteen years later, it may no longer be the most cutting-edge performance car, but its "wolf in sheep's clothing" charm can still captivate those who truly understand cars.
