Holden Torana LC GTR XU-1
The introduction of the Torana GTR was a controversial move by General Motors Australia. This was because the car broke the muscle car mold. It was somewhat smaller and lighter than the Monaro. It also featured a six-cylinder engine instead of a V8. Under the hood was the tuned version of a common 3.3-liter inline six paired with triple Stromberg carburetors.
The combo was good for 200 HP. With its small weight, the Torana GTR delivered good performance. The car was also successful in racing but mostly on rally stages and events (via Motor Classica). Holden’s racing team experimented with the V8-powered Torana. But this model never went out of the prototype stage. That was a shame since a V8 engine in a small car would be extremely interesting.
