The first Opel Ascona (Opel Ascona A) was launched in October 1970 in 2 and 4-door sedan and a 3-door station wagon. Originally, the Ascona was built as a replacement to the Kadett but during the development, Open decided to carry on with the model and make it as a smaller vehicle making the Ascona stand between the Opel Kadett and Opel Rekord. The car was offered with 3 petrol engine choices: 60 PS 1.2-litre OHV, 60-80 PS 1.6-litre CIH, and 88-90 PS 1.9-litre CIH straight-4s – all of the motors were coupled with a single barrel carburettor. The biggest engined model had a successful career in WRC. In 1974, the special version of the Ascona SR was developed featuring two single-barrel Solex carbs lifting the power to 125 PS.
