Porsche 911

A rear-engined, air-cooled sports car launched in 1963 as a replacement for the 356, and never actually replaced since: every 911 built in the sixty years after it, water-cooled or not, has kept the same basic layout and the same name.^[1] Markey covers two of its eight generations: the original air-cooled car of 1964–1989, which established the shape, the flat-six layout and the Targa roof; and the current 992, the seventh distinct generation, still recognisably the same idea with a twin-turbo flat-six and, on some models, mild-hybrid assistance. The five generations between them (964, 993, 996, 997 and 991) are not yet catalogued here.
