1994 saw an aerodynamic facelift for the 911 (now called the 993). Improvements to the car's suspension, along with widened rear wheel arches, significantly improved cornering, reduced oversteer, and allowed for a quieter, more comfortable ride. The optional all-wheel-drive system was also revamped with a simpler, lighter mechanism, offering a notable improvement in handling.
The 993 Turbo—the first Porsche Turbo with all-wheel drive—was released in 1995. 1997 saw the brief release of a 993 Turbo S, which produced 424-hp in the US and 450-hp elsewhere. Just 183 were sold.
As the final air-cooled incarnation of the 911, 993s are valued by collectors for their place in history, as well as for their reliability and performance.
