The Avenger was manufactured under the Hillman marque by the Rootes Group from 1970 until 1976.

Named to evoke memories of the Sunbeam Tiger, the Avenger Tiger concept began as a publicity exercise before the Tiger model itself was launched in 1972.

Modifications included the 1500 GT engine with an improved cylinder head with enlarged valves, twin Weber carburettors and uprated suspension.

A distinctive yellow colour scheme with a bonnet bulge, rear spoiler and side stripes was standard, set off with "Avenger Tiger" lettering on the rear quarters.
