The Viva Brabham was a half-hearted effort at injecting some vigour into the HB range but the same couldn’t be said of the 1968 Viva GT. For this was a storming machine that gave the Viva a heady degree of sportiness absent before. To achieve this, Vauxhall dropped in the 1975cc engine from the Victor, adorned with twin carburettors and mated with a close ratio gearbox. This unleashed 104 horses on the small car, giving 100mph. The suspension was uprated, while bonnet scoops, a black grille, black bonnet and contrasting white body made it look the part. Vauxhall’s equivalent of the Lotus Cortina.
