The 911 Turbo (or 930 as it is sometimes known) bought the already 12 year old 911 firmly into the supercar league. Following on from their racing development, Porsche became the first manufacturer to put a Turbo charger in a mainstream production car, enabling the 911 to accelerate from 0-60mph in just over 5 seconds. This performance was not at the cost of reliability as Porsche offered 12,000 mile service intervals and a 6 year anti-corrosion warranty - back in 1975!
The 'whale tailed' Turbo underwent welcome improvements in 1978 with the engine enlarged to 3.3 litres and cross drilled, ventilated disc brakes offering exceptional stopping power - always a 911's forte, just don't mention the on the limit handling! Ultra expensive 'flat-nose' Turbo was available from 1983.
