The new Audi S8 has 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.
The new Audi 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 saloon or a truly dynamic sports car – it’s entirely up to the driver.
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.
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.
The new Audi S8 offers a progressive technology experience with new digital services and state-of-the-art connectivity. The MMI touch response operating concept is fully digital. The driver controls nearly all functions via two large displays. The driver can also use natural speech control, which offers virtually unlimited freedom when formulating questions and commands. The answers are provided either from information stored on board or from the cloud. Alexa, Amazon’s cloud-based voice assistant, is also available as an option. All driving-relevant displays appear in the Audi virtual cockpit, which can be switched between two views. While the tachometer and speedometer are displayed as large dial-type gages in driving mode, the map is the center of attention in infotainment mode. Both views have S-specific red graphical details. A special S-performance layout for the Audi virtual cockpit where the central focus is the tachometer, displayed as a square graph, and the output and torque are shown as percentages can also be selected in the MMI. The optional head-up display can display important information on the windshield.
MMI navigation plus serves as the infotainment and media centre in the new Audi S8. Besides the integration of the Amazon Alexa voice assistant, the extensive Audi connect range includes numerous car-to-X services that draw on the swarm intelligence of the Audi fleet. Traffic light information is a new feature that Audi is adding successively in selected European cities. Thanks to the interconnection with the city’s infrastructure, the vehicle receives information from the central traffic light computer via a server, which allows the driver to select a speed to match the next green-light phase. The Audi virtual cockpit displays an individual speed recommendation as well as the remaining time until the next green-light phase if the driver is already waiting at a red light. The system thus contributes to a predictive and efficient driving style and facilitates a steady flow of traffic.
Online traffic sign information, hazard alerts and on‑street parking round out the range of car-to-X services. The myAudi app connects the car to the customer’s smartphone so that they can easily send destinations to the car from their sofa. The Audi smartphone interface brings Android Auto and wirelessly Apple Car Play on board. High-end components such as the Bang & Olufsen 3D Advanced Sound System and the Audi phone box round out the infotainment lineup in the new Audi S8.
