Well known for its Regal and Robin three-wheel cars, Reliant also built four wheel sports cars. In 1964 the Sabre was replaced by a new GT car, designed by Ogle. The Scimitar GT was a glass–fibre bodied 2+2 coupé, with a Ford straight six. By the end of the 'Sixties, Reliant were experimenting with the sports estate.

The Scimitar GTE of 1968 was a sports touring estate car for four adults and their luggage. Like the GT, the GTE used a steel chassis with a glass-fibre body. The engine was now Ford's V6 3 litre. In 1971 the GTE was revised with an upgraded interior and increased power and a new, larger model, was launched in 1976.
