Vauxhall Magnum

The Vauxhall Magnum is a car which was manufactured by Vauxhall from 1973 to 1978. First seen at the London Motor Show in October 1973, the Magnum was an HC Viva with a larger engine, more luxurious interior, higher trim level and four rather than two headlights. It shared its suspension and drive train with the larger-engined variants of the Vauxhall Viva and Firenza.
The smaller-engined version used the 1800 cc Slant-Four engine, and a twin-dial instrument panel, while the more powerful version used the 2279 cc Slant-Four and had a seven-dial instrument panel. Both were available in 2- and 4-door versions, a 3-door fastback estate and a coupé. All had "Rostyle" wheels. Confusingly, it was also possible to buy certain Viva models with the larger engines, but with vinyl interior trim. The continuing lack of coherency of the model range during that period was one of Vauxhall's main marketing problems. Late in the model's life there was a mild "upgrade" which saw the 2300 switch from twin to single carb with a drop of 2 hp to 108 hp, although the 1800 jumped from 77 hp to 88 hp which cut the 0–60 mph time by 3s to 12. 5s, and raised the top speed to 100 mph from 93 mph previously....
