The original 911, built for twenty-five years without a full replacement (what changed underneath it was engine size, fuel injection and, from 1974, US-mandated impact bumpers, not the basic recipe of a flat-six hung out behind the rear axle).[1] It is also the generation that gave the 911 line its Targa roof, introduced in 1966 as an open-topped body that could still meet the US rollover rules a full convertible could not.
The two trims recorded here sit at opposite ends of the range. The base 2.0 of 1964 made 130 PS from an air-cooled 2.0-litre flat-six; weight and torque figures for that earliest car are not reliably sourced in the article body and are left blank rather than borrowed from a later, heavier model year. The 930 Turbo of 1978, sold in North America simply as the Porsche Turbo, added forced induction and an intercooler for 300 PS. It is a car remembered as much for its turbo lag and demanding handling as for being, at the time, the fastest production Porsche sold.
