The first generation of the Porsche 911 begins in late 1964 and goes through 1968. Often described as the early 911, these vehicles are highly desirable today given their rarity and significance within automotive history. During this period, Porsche would make continuous improvements and tweaks to the body, to its short wheelbase (SWB) chassis, and to its venerable 2.0 liter engine, making each model year distinct from each other. Model year 1968 would be the last for the early 911, a transition that would begin with the introduction of the higher output 911S in 1967, followed by the 911L and a new entry level 911T in 1968, and finally, the 911E in 1969.
