Background
Having no doubt seen how well the approach had worked for arch-rivals Ford, by 1976 Vauxhall's Chairman, Bob Price, had his heart set on the marque competing in international rallying.
Entry into Group 4 required the building of 400 'homologation specials' for general sale, the result of which was a fast, poised and satisfyingly loud machine with 135hp on tap.
When used in anger in forest stages and on dirt tracks, the works rally versions developed by Blydenstein Racing delivered impressive results in the hands of rally Hall-of-Famers such as Pentii Airikkala, Jimmy McRae and Tony Pond.
The car presented a serious challenge to the most successful rally car of the time, the Ford Escort, winning the British Open Rally Championship for Drivers in 1979 and for Manufacturers in 1981.
The road-going Chevette ‘homologation special’, or ‘HS’ as it was known, derived its formidable motive power from a 2.3-litre ‘slant four’ engine with a 16V cylinder head.
Opel’s Kadett C GT/E provided the blueprint for the suspension and rear axle, while the gearbox was a Getrag 5-speed unit.
Chevrolet Vega alloy wheels sat at each corner (and looked a lot like the Avon wheels used on the ‘Droop Snoot’ Firenza), and a GRP air dam was fitted up front.
The HS was available only in Starfire Silver, with red striped decals, and a red and black tartan interior.
