Porsche 911

This photographic history dissects the evolution of Posche's 911 engine, from its earliest stages of development to its unveiling at the Frankfurt Motor Show in 1963 and the introduction in 1997 of the 996 variant. In addition to stock powerplants, there is also coverage of race editions and the significant tweaks that Porsche implemented over the course of four decades, including numerous changes to the engine's displacement volume and the introduction of turbo models in Europe and the United States. A year-by-year spec chart is accompanied by a photo of a model representing each year.
