The New Audi S8 for Model Year 2013

The New Audi S8 for Model Year 2013

• The most powerful sedan in Audi of America’s history features an all-new 4.0 liter twin-turbo engine generating 520 hp

• Innovative efficiency technologies though active Audi cylinder on demand ™
• Audi S8 signifies the next chapter of our engine downsizing strategy yielding more power and efficiency

The new Audi S8 elevates the level of refined performance in the flagship Audi A8 lineup, while advancing the Audi S8 lineage into its third generation. Building on the already agile A8, which utilizes Audi ASF® aluminum space frame technology to achieve a lightweight vehicle chassis, the S8 delivers more performance through its new 4.0 liter twin-turbo engine, responsive sport air suspension, high performance brake system and performance-inspired design elements.

Performance

The all-new 4.0 TFSI® brings the engine downsizing strategy already seen in other Audi vehicle segments to the high-performance class. Twin turbo-charging gives the V8 outstanding power at 520 hp and 479 lb-ft of torque to propel the S8 from 0 to 60 mph in an impressive 3.9 seconds and a governed top speed of 155 mph. The innovative cylinder head design packages the turbochargers and intercooler between the V-bank to provide shorter exhaust paths to the twin scroll turbochargers for impressive engine response. Compared to the previous S8 V10 engine, the new S8 delivers 16 percent more power — yet consumes 27 percent less fuel. Mated to the eight-speed automatic Tiptronic® transmission that delivers responsive shifts and two overdrive top gears, the S8 powertrain provides effortless acceleration and efficiency.

New fuel efficiency measures include Audi cylinder on demand technology that deactivates four of the eight cylinders at lower loads, reducing fuel consumption by up to 10 percent at moderate highway speeds. When the V8 engine switches to V4 mode, the active noise cancellation system negates undesirable changes in engine/exhaust sound. Active engine mounts further dampen vibrations at lower frequencies to make the Audi cylinder on demand technology transition imperceptible to the vehicle’s occupants. Combined with drive by wire throttle and modern engine design, these collective technical innovations demonstrate the Audi philosophy of delivering impressive performance and improved efficiency.

In order to complement the power of the S8, the chassis comes standard with a sport-tuned adaptive air suspension adjustable to three levels. These work in conjunction with dynamic steering to deliver enhanced handling and steering response with the refined ride comfort drivers expect in a premium sedan.
