Audi's large-car A8 series -- cast on a unitized aluminum structure, then fitted with sophisticated mechanical systems and extravagant luxuries -- comes in two lengths. A8L rides on a stretched wheelbase with generous legroom for riders in the rear quarters. A8 also appears with wheelbase pared slightly and five inches trimmed from the overall length.

Both A8 and A8L stock Audi's aluminum 4.2-liter V8 pumping 335 hp through a ZF six-speed electronic automatic transmission with Tiptronic manual shift mode. Both also contain Audi's Quattro AWD equipment plus computerized anti-lock brake system (ABS) and electronic stabilization program (ESP).

Then there's the A8L 6.0, Audi's top car, with a W-shaped 12-cylinder engine displacing 6.0 liters and producing 450 hp through a six-speed Tiptronic automatic.

New equipment on all A8 cars in 2006 ranges from adaptive front headlamps to Rainsensor and the Audi Parking System with a graphic display.
