STaSIS may not yet be a household name, but with more cars like these, that may change. Based on the Audi S5, the Signature Series S5 comes in two levels of trim called Touring or Challenge Edition.

The Touring Edition comes with Ohlins SL dampers, 20 inch STaSIS Monolite RS 147 forged wheels and a T-304 stainless steel exhaust while the Challenge Edition features a 370-mm Alcon Mono6 front brake upgrade, Torsen center differential, anti-roll bar package and an ECU upgrade estimated at an additional 15 hp/20 lbft. Also new Yokohama Advan Sport tires were added.

With the new improvements, the Signature Series S5 sprints from 0-60 mph in just 4.6 seconds—that’s half a second faster than the "standard” Audi S5. With these kind of numbers, the car is faster than the BMW 650i, Mercedes CLK 550 and the Lexus IS-F. All this performance comes at a price: $9,995 for the Touring Edition and $13,995 for the Challenge Edition - both with the security of a 4-year/50,000 mile warranty.
