in early 2000s GT racing, if you wanted to race you had to build a road version of your race car. this meant cars such as the ferrari 360 N-GT, porsche 911 GT3-R, and BMW M3 GTR all had a hotted up homologation special road car version.

these three cars were raced across the world. ferrari and porsche dominated the FIA GT championship, while the M3 GTR showed the american’s how it’s done in the american le mans series, taking the championship before going on to conquer the nurburgring 24 hour.
these three cars also raced here in australia, in our nations cup championship. they faced stiff competition from viper GTS-Rs, mosler MT900s, and lamborghini diablo GTRs, but their toughest foe was one the world hadn’t yet seen, one that hadn’t left the confines of the island it was born upon - the holden monaro 427C.
holden monaro HRT427 / holden monaro 427C
this monster was powered by a massive 7.0 litre, 427ci, V8. taken directly out of the corvette C5.R race car and producing upwards of 550hp. it was developed by a small group of people at garry rogers motorsport, a team who was competing in the V8 supercars series at the time.
it was a force to be reckoned with in the nations cup championship, but it’s biggest successes were at the bathurst 24 hour races in 2002 and 2003. it dominated both races, beating the worlds best GT cars with simple ease. ferrari, porsche, BMW, lamborghini, and mosler didn’t stand a chance against australias weapon of choice.
the problem was, the road-going version, the monaro HRT427, never made it to showroom floors. they planned to build 50 cars, and they were able to fill out 80 orders, but it became apparent that ensuring the car was legal for australian road rules was far too expensive of a job for holden.
despite the car being rigorously tested, and the project in it’s latter stages, the plug was pulled and only two road cars were ever made. one was kept by holden, and the other was sold to a private collector. had these cars been made and sold, the monaro would have become eligible to race worldwide, like it’s compatriots.
the vision of the 427C racing down the mulsanne straight at le mans is one that will never leave an aussie motorsport fans head, and that’s why australia needs this car in the new forza motorsport.
