For the enthusiasts, the S6 is an executive sedan that can really move- Autotrader

The 2021 Audi S6 is powered by a 2.9L twin-turbocharged V6 that's assisted by a 48-volt hybrid system to power an electric supercharger for additional boost. The combined output from this mill is an impressive 444 hp and 429 lb-ft of torque. The engine is mated to an 8-speed automatic transmission that powers all 4 wheels of this sedan as the S6 gets Audi's Quattro AWD drivetrain as standard. 

To describe the driving dynamics of the 2021 S6, the words sublime and ethereal are perfect. The Quattro AWD system drives the front wheels unless the rear wheels are necessary due to weather conditions. Normally, 21-inch wheels wrapped around in 35 series performance tires would destroy a car's ride quality. But that's not the case with the S6. The steering is progressive and guides the vehicle perfectly. 

If you are looking for a quick 5-seater sedan then the S6 will not disappoint you.

The BMW M550i is the only vehicle here that gets a powerful V8 engine while all the others offer a 6-cylinder engine. Owing to its powerful engine, it acceleration is the quickest among its rivals. The Mercedes-AMG E 53  impresses with its performance despite producing just 429 horses and shares the second spot with the S6. The Maserati Ghibli S is the slowest contender in this competition.

The 2021 A6 hits most of the right notes for a luxury sedan - The Car Connection

The exterior styling of the 2021 Audi S6 is a typical sedan-like look with a long and broad silhouette, coming straight out of the A6. The front look is characterized by bold and aggressive styling, with angular and slim headlamps, looking you straight in the eyes. The 2021 S6 sits 4.6 inches above the ground, which is decent for a sedan. This much ground clearance is enough to escape the scraping of the underbelly. Its 115.3-inch wheelbase is comparatively smaller than its rivals meaning slightly less interior room.

  On the sides, bold, definite creases flow from the front towards the back, giving the otherwise bland side profile a much-needed character. A chrome strip defines the character of the sedan and holds the center point in its rear profile. Hugging them are the two slim LED tail lamps with indicators. Twin chrome double exhaust completes the folio with much precision and simplicity making the sedan look sporty and aggressive while keeping the Audi design language true to its name.

The BMW M550i's ground clearance is 0.6 inches higher than the S6. This helps it to absorb road shocks, therefore, improving ride comfort. The wheelbase of the Maserati Ghibli S is nearly 3 inches wider when compared to the S6. At higher speeds, it contributes to a more stable ride. The less curb weight of the Mercedes-AMG E 53 reflects in its on-road performance. Some of the most noteworthy exterior features of the 2021 Audi S6 are:

• Galvanized steel/aluminum body material
• Power-folding auto-dimming exterior mirrors
• Chrome exhaust tips
• Chrome metal-look grille
• Metal-look front bumper insert
• 21-inch alloy wheels
• Aluminum window trim
• LED headlamps, DRLs, and brake lights
