9. 1976 Leyland Force 7V
Even though the Force 7 was a stillborn project that never made it to the market, it was a true Australian muscle car. Australian Leyland, a subsidiary of British Leyland, built the Force 7. They designed it as a coupe version in the Leyland P76 model range. They presented the P76 saloon model in 1973. It received a good initial reception by the Australian buyers, so Leyland started thinking about a coupe version that could battle the Ford and Holden muscle models.
They called it the Force 7 and it was a coupe version that included a number of interesting features. They gave it an all-alloy 4.4-liter V8 engine based on the Rover 3.5-liter unit. Unfortunately, the styling and quality weren’t exactly good, so after less than 60 pre-production examples, Leyland canceled the project, scrapping most of the cars. Today, only 10 Force 7s exists, making it one of the rarest Australian muscle cars.
