Vauxhall Magnum

The Magnum was a car manufactured by Vauxhall Motors from 1974 to 1978. It was an HC Viva with larger engines, more luxurious interior, higher trim level and twin headlights. It shared the same suspension and drive train of the Viva.

The smaller engined version used the 1800cc Slant Four engine, and a twin-dial instrument panel, while the larger engined variant used the 2300cc Slant Four and had a 7-dial instrument panel. Both were available in 2 and 4 door versions, and had "Rostyle" wheels. Confusingly, it was also possible to buy Viva models with these same engine options, but with vinyl interior trim. The lack of coherency of the model range during that period was one of Vauxhall's main marketing problems.

The Magnum badge also superseded the Firenza badge used on the 2-door coupé model, which name was then used exclusively for the HPF "droopsnoot" model (see Firenza). The model range continued until 1978, when it was rebadged as the Viva GLS, in a bid to shore up the increasingly poor sales of the model. The Viva range was finally discontinued in 1979.

A special variant of the Magnum estate, known as the Sportshatch, was produced in limited numbers (197) in 1976. This model used the "droopsnoot" nosecone, 2.3 engine and running gear from the HPF Firenza, alloy wheels and a distinctive paint job ("Extra Dark Wine" with bright red striping and highlights). This model was always rare and is now highly collectable.

Performance was quite brisk, but fuel economy was never the Magnum's strong point.
