The Sunbeam Rapier is an automobile produced by Rootes Group from 1955 until 1976, in two different generations, the "Series" cars (which underwent several revisions) and the later (1967–76) fastback shape, part of the "Arrow" range.
The first generation Rapier was the first of the "Audax" range of light cars produced by the Rootes Group, in this instance as part of their Sunbeam marque. Announced at the London Motor Show in October 1955, it preceded its Hillman Minx and Singer Gazelle counterparts which were not introduced until 1956.
A four-seat, two-door hardtop coupé – designated Series I with the introduction of the Series II in 1958 – it was different from the Sunbeam Mark III, the car it would eventually replace. Although designed "in house" by the Rootes Group, it was inspired, via the Raymond Loewy design organisation, by the new-generation Studebaker coupés of 1953.
