Introduced in 1978. It was fitted with a turbocharged version of the 2-litre engine. The body was originally a 3-door combi coupé version but later in 1979-80 the company produced a two-door model, which was a limited homologation exercise to enable the production of a rally car. It was available in Cardinal red, Sterling silver, Anthracite grey, and Black; the two-door was available in metallic green. The Turbo S was a special model with factory-mounted water injection, giving an extra 15–20 PS. In 1978 there was a very limited edition of a little over 100 five-door 99 Turbos. They were only available in Cardinal red.
