The 1989/90 change of model year saw the launch of the Porsche 911, 964 series onto the market. This 911 model was initially available as a Coupe Targa and Convertible. From model year 1991 onwards Porsche also introduced its top-of-the-line model – the Turbo – into this series.
In spite of bearing a major similarity in terms of look to the naturally-aspirated model, the extended wings remained. This meant that the new Porsche could retain its turbo look. — Porsche
