Ford may have given Australia the Falcon XR GT in 1967. But you could argue Australia’s first true muscle car didn’t sprout until a year later.

Before you burn your MOTOR collection, Ford fans, we’re not rallying the eviction of the ’67 Bathurst trophy. But if you lined up the XR against everything considered ‘muscly’ over in the States during the 60s, it’d look like a cougar trying to blend in with lions.

Ford’s Mustang, Pontiac’s GTO, Dodge’s Challenger, AMC’s Machine were the pin-ups and while these car’s weren’t defined by specifics, things like a big American V8, sloping roof, and two doors were the main markers. The latter criteria’s lost on the XR.

Holden’s answer to the Falcon XR GT wasn’t something ‘Mustang-bred’. It was a thoroughbred, applying the muscle maxim to its looks, performance, and spirit. Its pillar-less body was just as stiff as the sedan’s, a littler broader too, while its lines were softer and timeless compared to American counterparts.

The fact it was revealed months before the race that stops a nation was not at all a coincidence. Both Ford and Holden were very well established in Australia by then and while they knew building Aussie cars, in Australia, for Aussie people, was good for business, they also realised winning races was, too.

That didn’t matter because sucking through a Rorchester covered four-barrel carbie, and blowing out a freer exhaust, it made a still-respectable-today 184kW at 4800rpm and 443Nm at 3200rpm. Holden could have dropped in the 327 and dusted its hands on a job well done, but Bathurst beckoned.

So a standard Opel-sourced four-speed was ditched for a Corvette unit, complete with close-ratio gears and short-shift throw. The floating rear-end was pinched from Camaro-Chevelle, which housed an LSD which could be specified with a wide-range of final drives. All the way from 3.08 to 4.88.

Priced $3790 in ’68, it would cost circa $50K in today’s money after inflation. Unleashed at Mount Panorama, it caught Ford with its pants down, taking first, second, third, and fifth outright. At one point it bettered the XR GT’s best laptime from the year before by 5.7 seconds – and at the race’s end left the highest-placed Ford Falcon in seventh place.

It was a crushing defeat and a defiant way to step into the ring. Australia had its first ‘muscle’ car. And Holden had its first Bathurst victory. As we’ll see with our next three legends, these milestones would change the brand and local motorsport forever.
