Der Manta B, der 1975 den Manta A ablöste, basierte technisch größtenteils auf dem Opel Ascona B. Sein Radstand war im Vergleich zum Vorgängermodell länger, außerdem hatte er eine gestrecktere, kantigere Form mit großen rechteckigen Scheinwerfern. Das Fahrzeug erhielt durch Opels Beibehaltung des klassischen Layouts mit Frontmotor und Hinterradantrieb agile Fahreigenschaften, was es bei Enthusiasten beliebt machte.
Im Laufe der 13 Jahre, in denen der Manta B produziert wurde, wurden verschiedene Anpassungen und Erweiterungen des Modells vorgenommen.
