As a V8 engine with mild hybrid technology, the high-performance powerplant in the Audi S8 offers not only maximum smoothness, but with an output of 420 kW (571 PS), 800 Nm (590.0 lb-ft) of torque and two turbochargers also the certainty that ample power is available for any situation. Top speed is electronically limited to 250 km/h (155.3 mph) it takes just 3.8 seconds to accelerate from zero to 100 km/h (62.1 mph). Iron-lined cylinder barrels in the aluminum crankcase 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 reduce fuel consumption. Its 48-volt belt alternator starter and the additional lithium-ion battery enable coasting with the engine switched off, fast restart and an extended start-stop range. Fuel savings of up to 0.8 liters per 100 kilometers are possible in everyday driving. 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 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 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 precisely. The maximum roll angle during fast cornering is just roughly 2.5 degrees. With the standard suspension, it is around 5 degrees. The situational distribution of roll moments enables self-steering that is neutral or minimally oversteering.
