Audi's A8 is big, fast and exceptionally comfortable. It rides like a luxury car, yet handles like a sports sedan. It's a rock at high speeds, extremely stable.
Those things can be said for most, if not all, cars in the $60,000-plus price range. Buyers in this class expect the best of everything, and they should. The A8, however, differs from its competitors in two key ways. All-aluminum construction yields lighter weight and increased crash protection; and quattro all-wheel drive provides a measure of security and outright grip that is only available with that four-circle badge.
