Audi’s Executive Performance S8 Renewed at Frankfurt
Away from its regular role as a commuter for diplomats and other dignitaries, Audi’s largest sedan has been given the change to venture into super sedan territory since 1994. Available in the United States since 1999, the Audi S8 became a high-powered extension of the Germany premium car brand’s biggest four-door. Success of the first generation model brought forth the second generation S8 in 2006 utilizing the Audi’s quattro drive amongst many performance tweaks for an all-out battle with BMW M and Mercedes-Benz AMG competitors.
With the base A8 receiving a modernization during the 2011 model year, Audi left observers waiting a year until presenting the third and latest generation of the S8 sedan. Worth the wait, the Audi S8 debuts at the 2011 Frankfurt Motor Show ahead of its upcoming release.
Designed on the refreshed lines of the Audi A8, the S8 sports sedan is shaped with an abundance of aluminum. The look of aluminum is accented within the Audi S8’s front grille, mirrors and along the vehicle’s bumper. Apart from the look of aluminum surfaces, the Audi S8 comes in 13 exterior colour tones including Daytona Gray and Prizm Silver (two colours not available on the A8 model). A diffuser insert is found on the backside of Audi S8 with twin oval exhaust pipes presented on the rear corners.

A 360 degree parking camera, Audi’s MMI with navigation, adaptive cruise control and a 19-speaker Bang & Olufsen Advanced Sound System are all standard S8 equipment.
The heart and soul of the newest Audi S8 is the return to a V-8 engine. Debuting with a 340 horsepower, 4.2 liter V-8 powerplant in the S8‘s first generation, the Audi sedan performance upgrade added a larger, more powerful engine the second generation. Competing in a German battle of high cylinder count with the previous generation BMW M5 and Mercedes-Benz S63 rivals, the Audi S8 upgraded from a V-8 to a 5.2 liter V-10 powerplant in the 2006 model year. Propelled by 450 horsepower, the past V-10 variation of the Audi S8 delivered unhindered performance and fair fuel economy through FSI gasoline direct injection rated at almost 18 miles per gallon average by the auto company.
For the third-generation Audi S8, the newly developed V-8 engine features the highest horsepower-per-liter ratio of any incarnation of the German luxury car brand’s top four-door. A 520 horsepower engine using twin-turbochargers, the 4.0 TFSI powerplant of the Audi S8 engine accounts for 130 horsepower per single liter of engine displacement. Pounding out 70 horsepower more than its replacement engine, the 4.0 TFSI also delivers over 479 pounds-feet of torque through the A8’s quattro drivetrain. A high output engine combining the multiple turbochargers with gasoline direct injection for dynamite performance, the Audi S8’s 4.0 TFSI layout contributes to more efficient power creation. Cylinder deactivation and start-stop systems assure the new S8 muscular performance is available at just the right time. For the rest of the driving journey, the Audi S8 sedan accomplishes vastly improved fuel economy compared to its predecessor. Rated in consuming 23 percent less fuel than the 2010 model Audi S8, 4.0 TFSI V-8 engine of the latest S8 moves the 4,354-pound super sedan an average of 23 miles per gallon.
Channelling the 520 horsepower through an eight-speed tiptronic gearbox, the Audi S8 supplies the driver with a sensation of sport driving while also respecting luxury car smoothness. The all-wheel drive quattro system is supported by two differentials including the added sport differential added to the rear axle of the S8 for ideal wheel movement.
