3rd Gen: Audi S6 (C6 & C6.5) 2005-2011

Starting in 2003, something remarkable happened in the world of German luxury cars. BMW, Mercedes-Benz, and Audi all went a bit crazy in a friendly competition to create the fastest and sportiest vehicles. Let's dive into this exciting era.

Mercedes-Benz made headlines by introducing the world's fastest sedan, the E55, which packed a supercharged V8 engine. Meanwhile, BMW took a different approach with their E60 M5, opting for a naturally aspirated engine that sounded like a Formula 1 car.

Audi, on the other hand, made a fascinating move. They had recently acquired Lamborghini, and while it didn't make sense to put a diesel engine in a Lamborghini, it made perfect sense to drop a Lamborghini V10 engine into a regular A6 and call it the S6. But it wasn't just about the engine; the S6 received upgrades inside and out, including sportier seats and distinctive exterior features with quad exhaust tips.

This period marked an intense competition among these German automakers, each striving to create the ultimate sports sedan. It was during this time as well that Audi fitted a naturally aspirated V8 on a coupe, and thats how the S5 was born.

To handle all that power, Audi paired it with a specially designed 6-speed Tiptronic automatic gearbox. While it wasn't a fancy double-clutch system, it was optimized for high performance.

The Audi S6 wasn't your typical sedan; it featured Audi's famous quattro all-wheel-drive system with an electronic Torsen center differential. Plus, there was a limited-slip differential in the rear to ensure that power was distributed effectively to all four wheels, giving you outstanding traction and control.

Now, let's talk about performance. Audi, Mercedes-Benz, and BMW had an informal agreement to limit their cars to a top speed of 250 kilometers per hour (155 miles per hour) for safety reasons. Even with this limitation, the S6's power and handling capabilities provided an exhilarating driving experience that thrilled enthusiasts worldwide.

BMW, Mercedes-Benz, and Audi have all come to realize that consumers are now placing a greater emphasis on luxury and refinement rather than just pure performance.

Audi, known for its precision engineering but also for potentially high maintenance costs due to its pursuit of maximum performance, has moved forward with its C7 lineup. In our opinion, the C7 S6 stands out as the best S6 model money can buy. It not only boasts improved reliability compared to its predecessors but also features a luxurious interior and a striking exterior design.

The C7 Audi S6, produced from 2012 to 2019, is a remarkable blend of power, luxury, and modern technology. Under the hood, it packs a robust 4.0-liter TFSI V8 engine that delivers an impressive 450 horsepower and 406 lb-ft of torque. This engine is mated to a responsive 7-speed automated manual transmission for quick gear shifts. Audi's Quattro all-wheel-drive system ensures excellent traction and stability, even in challenging driving conditions.

The S6 features a sport-tuned air suspension that allows drivers to customize the ride quality.

The inclusion of a sport differential enhances its cornering capabilities. Additional amenities include a sunroof, front and rear parking sensors, and luxurious diamond-stitched leather seats with heating and power adjustments.

The driver enjoys memory settings, a user-friendly 6-inch display, a rearview camera, and a comprehensive infotainment system with navigation and Bluetooth connectivity. Optional packages and standalone features, such as 20-inch wheels, LED headlights, rear side airbags, and a premium 15-speaker Bang & Olufsen sound system, provide further customization options.

5th Gen: AUDI S6 (C8) 2019 - Present

In the latest generation of the Audi S6, known as the C8, Audi has introduced a unique twist by offering a diesel version for Europe and a gasoline version for the U.S. market. This decision may seem unusual, but it has resulted in a car that's quite impressive.

The S6 is spacious inside and boasts a bold exterior design. It's designed to excel on the autobahn, the German highway, where it can comfortably cruise at speeds of up to 155 MPH (250 kph) with adaptive cruise control engaged.

Under the hood of the European version, you'll find a 3.0-liter V6 diesel engine equipped with both an electric supercharger and a turbocharger. This setup provides ample torque starting from as low as 2,500 rpm, peaking at 3,100 rpm. While this might seem like a modest torque range for a gasoline engine, it's more than sufficient for a diesel.

The engine produces a consistent 700 Nm (516.3 lb-ft) of torque, enabling the S6 to accelerate from 0 to 62 mph (100 kph) in just 5 seconds. The electric supercharger, which spins at around 70,000 rpm, effectively eliminates turbo-lag for instant power delivery.

To further enhance performance and handling, Audi has equipped the S6 with the Quattro all-wheel-drive system, all-wheel steering, electronic adaptive suspension, and an optional sport differential for the rear axle.

For markets outside Europe, the S6 offers a twin-turbo V6 gasoline engine generating 450 HP and 600 Nm (442.5 lb-ft) of torque. This version also features the electric supercharger (EPC) for an exhilarating driving experience.
