The S8, which Audi offers with the standard wheelbase, is the most powerful and sportiest model in the new A8 lineup. The 4.0 TFSI produces 382 kW (520 hp) and develops 650 Nm (479.42 lb-ft) of torque between 1,700 and 5,500 rpm. The sprint from 0 to 100 km/h (62.14 mph) only takes 4.1 seconds; its acceleration ends at a top speed of 250 km/h (155.34 mph). The V8 biturbo, whose sound is now even more sonorous, consumes on average 9.6 liters of fuel per 100 kilometers (24.50 US mpg), a CO2 equivalent of 225 grams per kilometer (362.10 g/mile).
Behind these top figures is the entire range of Audi’s technological expertise, from the layout of the cylinder heads with the hot side on the inside to the twin-scroll turbochargers to the cylinder on demand (COD) system, which shuts down four of the eight cylinders when operating under part load. The Active Noise Cancellation (ANC) system and the active engine mounts suppress undesired noise components and vibrations during these phases by producing precise antiphase vibrations.
The eight-speed tiptronic in the S8 also unites sportiness and efficiency. That keeps engine speed low, yet kicks down quickly and comfortably when prompted by the driver. The tiptronic delivers the power to a quattro drivetrain supplemented with the sport differential at the rear axle. Among the chassis highlights are the adaptive air suspension sport and dynamic steering. The differential, air suspension and dynamic steering receive S-specific tuning.
The standard wheels of the new Audi S8 measure 9 J x 20 and are shod with size 265/40 tires. Options extend up to exclusive 21-inch wheels with size 275/35 tires. The internally vented disc brakes have a diameter of 400 millimeters (15.75 in) up front and 365 (14.37 in) in the back.
S8 logos adorn the black, six-piston calipers up front. Audi also mounts optional carbon fiber ceramic discs with anthracite gray brake calipers.
Distinctive design details visualize the sporty character of the Audi S8. Its Singleframe grille is painted platinum gray and the horizontal double bars are finished in chrome. The three air inlets are separate from one another. The two large inlets on the outside are filled with honeycomb grilles and structured with thick chrome bars. The lower section of the front apron is a splitter shifted to the front.
On the flanks, body color trim strips on the sills and polished aluminum-look mirror housings catch the eye. The diffuser insert at the back is platinum gray and includes a two-layer blade in an aluminum-look finish. The exhaust system ends in twin oval tailpipes on each side of the car. S8 or V8 T badges can be found in the front, on the back and on the sides. The finish Daytona gray, pearl effect is reserved exclusively for the sporty top-of-the-line model.
Interior: Fine materials for sporty elegance
S-model interiors are characterized by the gray dials of the analog clock and the dial instruments with white needles. The inlays are Carbon Atlas and brushed aluminum, the door trim panels in Alcantara and the selector lever for the tiptronic is in carbon. The pedals and footrest shine in an aluminum-look finish. A red ring adorns the start-stop button; an S8 badge the steering wheel. There is a choice of four colors for the interior and ten colors for the upholstery. The standard comfort sport seats are covered in perforated Valcona leather and feature diamond-quilted center sections.
The sportiest model of the A8 family offers a very generous list of standard equipment, including LED headlights, ambient lighting, convenience key, four-zone automatic air conditioning, Bose surround sound system and MMI navigation plus with S8-specific welcome screen. An exclusive option for the S8 is the Audi design selection black/Vermont brown. The inlays here are called Carbon twill copper – a copper thread matching the color of the seat coverings runs through the carbon fabric.
