The Porsche 964, internally known as the 911/964, is a significant milestone in the evolution of the iconic Porsche 911. Introduced in 1989, the 964 marked the first major redesign of the 911 since its inception in 1963, introducing a plethora of advancements and refinements that cemented its position as a true technological powerhouse. The 964's design incorporated a wider track, increased wheelbase, and a more aerodynamically efficient body, resulting in a car that was not only more visually striking but also significantly more stable and capable on the road. The 964 also benefited from a new, multi-link suspension system that delivered both improved handling and a more comfortable ride.

Beyond its cosmetic and chassis enhancements, the 964 was equipped with a host of innovative features, including the first generation Tiptronic automatic transmission, a revolutionary technology that offered the convenience of an automatic transmission without sacrificing the performance that Porsche drivers demanded. This combination of advanced technology and classic 911 styling made the 964 a highly sought-after and desirable sports car, leaving an indelible mark on automotive history. The 964 was available in both two-wheel drive (Carrera 2) and all-wheel drive (Carrera 4) configurations, catering to a wide range of driving preferences and performance needs. The 964's legacy is one of both refinement and innovation, solidifying its position as a true icon of the automotive world.
