While it's essentially just a souped-up version of its maker's flagship A8 sedan, the 2007 Audi S8 is still pretty impressive in its own right. After all, it comes standard with a Lamborghini Gallardo 450hp 5.2L V-10 engine, and its six speed automatic transmission is equipped with the "Tiptronic" technology that allows you to manually shift gears, when necessary. Add to that the presence of overdrive and Audi's "Quattro" all-wheel drive system, and what you have is a seriously speedy sedan.

In fact, the S8 is as safe as it is swift, with a total of ten airbags protecting you and your passengers. The array includes the traditional dual-stage type in the front, as well as knee protection in the front, and side protection all the way around the car. In addition, there are anti-lock brakes and a traction control system.

Interior features of the S8 are quite cushy, including adjustable two-tone leather sport seats in front, and a three- spoke leather-trimmed steering wheel. The instrument panel has been specifically designed for this car, as well. As well, the side view mirrors are both heated and power-adjustable, and the sunroof is a standard feature.

As with the S6 and S4, the 2007 Audi S8 comes with a full appointment of entertainment options. A 6-disc CD player is standard, as is Bluetooth connectivity, but while the car is pre-wired for satellite radio, the actual component is an optional upgrade.

The MSRP of the 2007 Audi S8 is $92,000, but for a luxury sedan that can go from zero to 60mph in 4.66 seconds, that really doesn't seem exorbitant at all.
