In 1966 the HA Viva was replaced by the 1159cc-engined HB, originally only in 2-door form. A 3-door estate was added in 1967 and a 4-door saloon in 1968. The'coke bottle' styling came from Leo Pruneau at General Motors after they had comprehensively rejected the design sent by David Jones in Luton. The story goes that Pruneau was given just 3 hours to sketch something after the meeting had thrown out the British ideas. Management jumped at his proposal and told him to pack his bags for Vauxhall to ensure that his design was made the way it should be. At the time Pruneau had been around people who were designing the soon to be launched Chevrolet Camaro, and in essence the Viva HB was a small Camaro.A '90' option was offered to buyers giving a tuned engine and disc brakes supposedly enabling the Viva to do 90mph. In 1967 a Brabham version was offered giving even greater performance, and in June 1967 the Viva estate joined the range. In March 1968 the Viva GT was announced carrying the 2-litre slant four engine from the Vauxhall Victor FD. The 1599cc version of the slant four engine was given as an option from June 1968, but was not officially called the 'Viva 1600'. Four door Vivas were brought out in September 1968. Production ended in summer 1970.
