MUST QUALIFY FOR LOYALTY OR CONQUEST, DEAL ENDS 02/01/13, , ALL WEATHER MATS, COLD WEATHER PACKAGE, CAMERA ASSIST, LED HEADLIGHTS, COMFORT PACKAGE , , As with previous Audi A8s, the current model offers a near-perfect blend of luxury, performance, amenities and style, and is one of our favorite full-size luxury sedans. The A8 is available in standard and long-wheelbase (A8 L) forms, with the latter version laying claim to being the biggest luxury sedan., , Yet the A8 still weighs less than most of its rivals thanks to its unique aluminum construction. The 4.2-liter direct-injected V8 makes 372 horsepower and 328 pound-feet of torque and sends its power to all four wheels via an eight-speed automatic transmission. It's plenty capable for the vast majority of drivers. For more power-hungry pilots, there's also a 6.3-liter W12 that produces 500 hp and 463 lb-ft. The all-wheel-drive system has a rear-biased power split, which helps to provide the more sporting feel of a rear-drive performance sedan. For even more athleticism, a torque-vectoring limited-slip differential is available., , Of course the A8 comes loaded with all the latest high-tech features. Highlights include a dynamic steering system that can intervene with automatic countersteering in a slide, adaptive cruise control with stop-and-go capability, automatic emergency braking, and night vision with thermal imaging and pedestrian detection. Audi's MMI electronics interface is still in use but now features an additional touchpad interface that reads fingertip gestures as letters and commands. Google Earth mapping for the navigation system is another A8 exclusive., , Beyond the sumptuous cabin and all the luxury features, you're bound to be impressed by the big sedan's ride and handling characteristics. The suspension provides a comfortable ride without excessive float over bumps, and when pressed on a curvy road it proves surprisingly agile, with nicely weighted steering. Both trims boast generous standard features, including amenities like a navigation system and heated front and rear seats. Rear seat room is ample in the regular-wheelbase model, while the A8 L provides more than enough legroom for a pair of 6-footers., , The A8 undoubtedly lacks the snob appeal of its fellow Germans, but don't let that stop you. With its roomy, best-in-class cabin and excellent driving dynamics, this sedan shines as one of the strongest picks in its segment.
