New Audi S8, combines progressive luxury with dynamic athleticism while honing its reputation as the benchmark for Vorsprung durch Technik with innovative suspension systems. Its 4.0 TFSI engine – a biturbo eight-cylinder unit – produces 420 kW (571 hp) and an opulent 800 Nm (590 lb-ft) of torque (combined fuel consumption in l/100 km: 11.3–11.4* (20.8–20.6 US mpg); combined CO2 emissions in g/km: 258–260* (415.2–418.4 g/mi)). It is combined with MHEV technology for the perfect symbiosis of efficiency and comfort with exhilarating performance. The predictive active suspension, dynamic-all-wheel steering and quattro drive with sport differential provide for outstanding vehicle dynamics straight from the factory. The new Audi S8** uses specific design elements to express the sporty elegance of the sophisticated luxury sedan with pinpoint precision.
Impressive performance: the drive system
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 (combined fuel consumption in l/100 km: 11.3–11.4* (20.8–20.6 US mpg); combined CO2 emissions in g/km: 258–260* (415.2–418.4 g/mi)) 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.
Progressive and state-of-the-art: the equipment
Every detail of the new Audi S8′ reflects its character as a sporty luxury model. One particular highlight are the standard comfort customized contour seats in sport look. They feature wide-ranging power adjustment, pneumatically adjustable side bolsters and separate three-stage heating for each seat. What is more, they are optionally available with ventilation and massage functions. Customers can choose between the top leather grades Valcona and Unikat. The rear seats also offer numerous features for outstanding comfort and provide for a first-class atmosphere in the Audi S8**.
The 38 driver assistance systems that Audi provides for the new S8, are divided into the City and Tour packages. Adaptive cruise assist – the central system in the “Tour” package – stands out among the comprehensive range of assist systems. It combines the functions of adaptive cruise control, traffic jam assist and lane tracking. In conjunction with predictive efficiency assist, adaptive cruise assist brakes and accelerates the Audi S8′ in anticipation of the conditions ahead. In the City assist package, Audi pre sense side joins the systems pre sense front and pre sense rear to create Audi pre sense 360°. If the system detects an impending side impact, it can operate together with the predictive active suspension to instantly raise the body by as much as 80 millimeters (3.1 in). This brings the sill into a better position to absorb the impact energy, mitigating the potential consequences of the accident for the occupants.
The brain behind the driver assistance systems in the new S8, is a high-performance processing unit, the central driver assistance controller (zFAS). It continuously computes a differentiated model of the vehicle’s surroundings based on the data provided by the sensors. Fully equipped, there are five radar sensors, six cameras, twelve ultrasound sensors and a laser scanner on board.
