Joining the A8 model line, the high-power S8 sets itself apart from the competition. Encompassing a V8 engine with mild hybrid technology, the high-performance powertrain in the Audi S8 offers not only maximum smoothness, but with an output of 563 horsepower, 590lb-ft of torque and two turbochargers. The result is ample power available for nearly any situation. Top track speed is electronically limited to 155 mph. Iron-lined cylinder barrels in the aluminum crankcase can reduce friction for exceptionally smooth running. Automatically actuated flaps in the exhaust system underscore the impressive sound.
Sports car-level emotion and performance are paired with comfort and efficiency. The mild hybrid system (MHEV) works continuously to help increase fuel efficiency. Its 48-volt belt alternator starter and the additional lithium-ion battery enable fast restart and an extended start-stop range. The cylinder on demand system, which deactivates individual cylinders in low-load operating situations, provides for additional efficiency. The vehicle’s sound system features active noise cancellation to eliminate intrusive cabin noise for the ultimate in comfort.
The unique combination of innovative suspension components enables the flagship to cover the entire range from the smooth cruising of a luxury sedan to the dynamically performance-oriented handling of a sports car, all depending on the driver’s preference. The new S8 comes standard with the predictive active suspension. The high-tech system, which works in combination with the adaptive air suspension, can lift or push down each wheel separately via electromechanical actuators. It is therefore possible for the first time to actively control the body in certain driving situations and helps reduce pitch or roll during acceleration or braking. The front camera, which detects larger road surface irregularities, enables this to be done predictively. The Audi drive select system offers unique profiles from which to customize the drive experience. Through the comfort setting, even cornering can be a comfortable experience: The body leans into curves by as much as 3 degrees to help reduce the lateral acceleration acting on the occupants. In “dynamic” mode the S8 turns in tightly. The maximum roll angle during fast cornering is just roughly 2.5 degrees compared with around 5 degrees with the standard suspension. The active suspension enables another new function. The body is quickly raised by as much as 52.0 in when the door handle is actuated for an even more comfortable entry and exit.
The Audi S8 is redefining vehicle dexterity and maneuverability thanks to the dynamic all-wheel steering. This allows the independent adjustment of the steering angles at the front and rear axles. It therefore combines direct, agile steering response at low and medium speeds with supreme stability on the highway and a tight turning circle, thus resolving a frequent conflicting handling objective. The sport differential actively transfers torque between the rear wheels during fast cornering. When turning into or accelerating in a curve, most is directed to the outside wheel. This literally pushes the car into the curve and helps reduce understeer. In the case of oversteer, the sport differential on the rear axle transfers the drive torque to the inside wheel to help stabilize the S8. Dynamic all-wheel steering, the sport differential and the predictive active suspension are all standard equipment. The interplay of these systems is unique and helps ensure composed and performance handling. Customers can choose the optional high-performance carbon-fiber ceramic brake discs with a diameter of 16.5 inches at the front axle and 14.6 inches at the rear axle. The ceramic brakes are internally ventilated, low-wearing and including the calipers are 21.2 lb lighter than cast iron discs.
