An all new model from Chrysler owned Hillman made its debut in 1970, the Hillman Avenger. The Avenger was a mid-size family saloon aimed directly at the Morris Marina, Ford Escort and Vauxhall Viva, all of which were relatively new models of a similar size. As well as the usual "standard" models of the Avenger range two sporting variants, the competition bred Tiger model and an even rarer BRM version were also made available in small numbers.
The Avenger-BRM was really a built-to-order special for rallying produced for homologation reasons. The Avenger had special 16 valve BRM engines fitted in a choice of capacities including 1598cc,1798cc and even a 2000cc version. Customers could choose their own specification which usually consisted of uprated suspension and a five-speed ZF gearbox. Production of the Avenger-BRM started in 1974 and finished in 1977.
