A report from Wired describes some of the geeky features of the 2004 Audio A8 sedan.

Audi's flagship vehicle will contain 2 LCD displays and a potpourri of various toys and gadgets, including: solar-powered air conditioning that acts while you are away from the car, heated door locks (to keep them from freezing), adaptive cruise control, acoustic parking system, variable ground height, tire pressure monitoring, and OnStar services.
