The second generation Opel Ascona B was presented in the 1975 Frankfurt Motor Show. It was available as a two or four-door sedan. There were related two and three-door coupé models in the Opel Manta range. There was no estate body.

The 2.0 E model had a Bosch L-Jetronic electronic fuel injection, and a 2.0 L diesel motor was added to the Ascona B range in 1978. Engine range was larger than that of the Vauxhall Cavalier though not all engines were available in the UK.
