Audi's flagship sedan is the A8. The A8 stands apart from other large luxury sedans with its all-aluminum construction and standard all-wheel-drive. The A8 is offered in two lengths. At 202 inches in length, the standard A8 is no small car, but the longer A8L adds another 5 inches of wheelbase and length. This greatly increases legroom in the second row of seats. The A8 is loaded with standard features and amenities, but still offers a healthy list of options and packages to allow owners to customize it as far as their budgets will allow. Notable options include a panoramic sunroof, four-zone climate control, power-closing doors and a 19-speaker Bang & Olufsen sound system. Most A8 models equip a powerful V8 engine, but the W12 includes a decidedly unique engine configuration.

What Changed:

The S8 rejoins the A8 lineup. A twin-turbo 4.0l V8 produces 520-bhp and 479 lb-ft of torque. An eight-speed automatic transmission and quattro all-wheel-drive complete the driveline.
