The Holden Torana GTR-X was developed in the late 1960s by General Motors Australian branch. They were tasked with developing a sports car that could be inexpensive to produce and use existing components of the available models. The resulting concept was created using the serial car GTR-Xu, which was derived from the Vauxhall Vivas model.

Power to two-seater Torano GTX-R was a 3-liter six-cylinder engine that delivered 160 horsepower and 285 NM of torque. Power was sent to the rear wheels via a four-speed manual transmission. The top speed for the 2300-pound sports car was in the neighborhood of 210 km per hour. The car was relatively lightweight thanks, in part, to its fiberglass construction.

The car's interior featured gauges placed in a simple design aluminum panel, ergonomic seats with high backs, and a height-adjustable steering wheel.

For a while, the company considered putting the car into production. Several prototype models were constructed, and a promotional film was made. The project was halted due to concerns about the financial viability of the project.
