The Opel Ascona is a large family car produced in Germany in between 1970 and 1988. It was sold in three separate generations (A, B, C), starting with rear-wheel drive and ending with front-wheel drive. It was replaced by the Opel Vectra.

The Opel Ascona B was introduced in August 1975 at the Frankfurt Motor Show. It was produced in from 1975 to 1981 and was available as a 2/4-door sedan. The car retained the same range of engines as its predecessor. It was rear-wheel drive and engines were located in the front. Seven engines were available, from the 1.2-litre I4 to the 2.4-litre I4. In 1979 the car received a minor facelift, including plastic bumpers and a grey front grille. In total, more than 1.2 million examples of the Ascona B were produced.
