The Sunbeam Alpine is a sporty two-seat open car from Rootes Group's Sunbeam car marque. The original was launched in 1953 as the first vehicle from Sunbeam-Talbot to bear the Sunbeam name alone since the 1935 takeover of Sunbeam and Talbot by the Rootes Group.
The car has a four-cylinder 2267 cc engine from the saloon, but with a raised compression ratio. However, since it was developed from the saloon platform, it suffered from rigidity compromises despite extra side members in the chassis. The gearbox ratios were changed, and from 1954 an overdrive unit became standard. The gearchange lever was column-mounted.
The Alpine Mark I and Mark III (no Mark II was made) were hand-built – as was the 90 drophead coupé – at Thrupp & Maberly coachbuilders from 1953 to 1955, and remained in production for only two years. Of the 1582 automobiles produced, 961 were exported to the USA and Canada, 445 stayed in the UK, and 175 went to other world markets. It has been estimated that perhaps as few as 200 have survived.
A sapphire blue Alpine featured prominently in the 1955 Alfred Hitchcock film To Catch a Thief starring Cary Grant and Grace Kelly
