Background
The Sunbeam ‘Arrow’ Rapier Fastback coupé broke cover in 1967. A radical departure from the more rounded cars that had gone before, the two-door, four-seat coupé is based on the Hillman Hunter’s chassis.
Despite its humble roots (d’ya see what I did there?) the body panels were all new bar the rear valence – and what a gorgeous shape they created.
Fitted with the 1,725cc four-cylinder engine, its 88bhp was channelled to the rear axle via a four-speed manual gearbox, although a Borg-Warner automatic ‘box was available as an extra-cost option. Performance is adequate rather than startling, with 60mph arriving after 12.8 seconds on its way to a V-max of 103mph.
A high-performance H120 version was offered from October 1968. With a boot-lid spoiler, Rostyle wheels, a matt black radiator grille, polished sill trims, and unique badging, its mechanical upgrades include a close-ratio gearbox, a heavy-duty overdrive, and a high-ratio rear axle.
Plus a Holbay-tuned engine under the bonnet. Fitted with a modified cylinder head, a high-lift camshaft, tuned four-branch exhaust manifold and a different distributor, these upgrades conspired with twin Weber carburettors (fitted in place of the standard cars Strombergs) to lift the Rapier’s power to 110bhp, enough to propel it to 60mph in 11.1 seconds and go on to a top speed of 106mph.
