Why it matters

The Chevette HS was Vauxhall's first true homologation special. A minimum run of 400 cars was required so that Dealer Team Vauxhall could take on the Mk2 Escort in rallying. Its 16-valve twin-cam slant-four made it a strong performer, although Vauxhall struggled to sell the road cars.

History

Early competition cars used Lotus heads and ZF gearboxes, but the road cars have the in-house 2.3-litre slant-four from the Magnum with a special 16-valve twin-cam head and a Getrag gearbox. The axle, brakes and suspension came from the Kadett C GT/E and the alloy wheels from the Chevy Vega.

Vauxhall found the HS hard to sell. A limited dealer special, the HS-X, was resprayed in black and added 1,400 pounds to the 5,107 pound list price; only 10 were built. The last batch of 33 HS cars evolved into the HSR for 1980.

Identification guide

How to tell an original from a replica or later conversion.

Road cars carry the 2.3-litre 16-valve twin-cam head and Getrag gearbox, with a deeper airdam, spoilers and silver paint recalling the Droopsnoot. Kadett C GT/E running gear and Chevy Vega alloy wheels distinguish it from standard Chevettes. The black HS-X dealer special is a separate 10-car variant.
