The unique combination of innovative suspension components enables the flagship to cover the entire range from the velvety cruising of a luxury sedan to the dynamically taut handing of a sports car. 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 trim of the body in any driving situation and thus greatly reduce pitch or roll during acceleration or braking. The front camera, which detects larger road surface irregularities, enables this to be done predictively.
The new Audi S8 can be a highly comfortable luxury sedan or a truly dynamic sports car - it's entirely up to the driver. The Audi drive select system offers five profiles from which to choose. "Comfort +" mode is a new profile. It makes even cornering a comfortable experience: The body leans into curves by as much as 3 degrees to reduce the lateral acceleration acting on the occupants. In "dynamic" mode the S8 turns in tautly. The maximum roll angle during fast cornering is just roughly 2.5 degrees compared with around 5 degrees with the standard suspension. The situational distribution of roll moments enables self-steering that is neutral or minimally oversteering. The active suspension enables another new function. The body is quickly raised by as much as 50 mm (2.0 in) when the door handle is actuated for an even more comfortable entry and exit.
The Audi S8 is redefining the limits of physical possibility 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, sporty steering response at low and medium speeds with supreme stability on the highway and a tight turning circle, thus resolving a long-standing conflict of objectives. 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 nips any hint of understeer in the bud. In the case of oversteer, the sport differential on the rear axle transfers the drive torque to the inside wheel to 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 in its class and ensures composed and sporty handling in all situations. Customers can choose the optional high-performance carbon-fiber ceramic brake discs with a diameter of 420 millimeters (16.5 in) at the front axle and 370 millimeters (14.6 in) at the rear axle. The ceramic brakes are internally ventilated, low-wearing and including the calipers are 9.6 kilograms (21.2 lb) lighter than cast iron discs. Each of the front calipers has ten pistons.
Precise expression of sporty elegance: the design
The progressive, elegantly flowing exterior design of the model series gets some new accents with the new Audi S8. Bold interior and exterior design elements finely hone the sporty character. Wheels up to 21 inches in diameter are available for the 5.17 meter (17.0 ft) long sports sedan. Details on the front bumper, side sills and the exterior mirror housings as well as the two S-typical twin exhaust tailpipes emphasize the car's sporty and progressive character. The black styling package is also available as an option. Customers can choose from nine sophisticated color and design worlds, including the Audi design selection pastel silver, for the spacious interior, which conveys the relaxed atmosphere of a luxurious lounge.
Here the upper inlay - new and available exclusively in the Audi S8 - is made of Carbon Vector with a special 3D depth effect. Directly below that is an inlay of dark, brushed matt aluminum. Lighting options range up to HD matrix LED headlights with Audi laser light and OLED rear lights. In the major markets China, USA, Canada and South Korea, the Audi S8 will be available for the first time and exclusively with an extended wheelbase. The increased vehicle length and height means a significant increase in comfort for the occupants thanks to greater head and leg room.
