1980s VH project The possibility briefly existed in the early 1980s for a revival of the Monaro badge based on a combination of the
Holden VH Commodore and the
Opel Monza. With serious exploration of the concept, a Monza was shipped to Australia by
Peter Brock but the project was shelved as Holden was more preoccupied, at the time, with engineering work to revamp the Statesman and Gemini range as well as with the launch of the
JB Camira.
1998 Coupé This concept car, codenamed "
Monica", emerged 20 years after the last Monaro coupé. Publicly displayed at the 1998
Sydney Motor Show, the two-door Coupé was based on the then existing
VT-series
Holden Commodore, which, in turn, was based on a modified platform of the European
Opel Omega B.
Journalists quickly christened it the Monaro and orders came flooding in, thus encouraging Holden to produce it. The production model the third generation Monaro, known as the V2 series was eventually launched in 2001, by then based on the
VX Commodore.
2002 HRT 427 Displayed at the 2002
Sydney Motor Show, the
HRT 427 based on a modified Monaro bodyshell. The
MacPherson strut front suspension was replaced by an aluminium
double A-arm setup with adjustable dampers and a weight reduction program including a carbon fibre bonnet and magnesium wheels brought the car's weight down to just 1575 kg (3472 lb). a (7.0-litre) V8 engine from the
Corvette C5-R (based on the GM
LS7 design), producing at 6,000 rpm. This powerplant was built by Melbourne-based John Sidney Racing, renowned for its success in the Australian
Sprintcar and
NASCAR series. The transmission used was a custom
Tremec T-56 M12 six-speed manual gearbox with a heavy-duty 900 N·m clutch, giving the car a time of 4.4 seconds and a top speed of . Other unique fittings included:
AP Racing six-piston racing brakes, ram air induction, Motec instrument panel, two
Sparco Pro 2000 seats and a half roll cage. As a result, the project was eventually cancelled and all customer deposits received were refunded. The only HRT 427s in existence are two road cars and four racing versions (the latter built by
Garry Rogers Motorsport for use in the short-lived
Bathurst 24 Hour race and
Australian Nations Cup Championship), each of which cost about A$500,000 to build. The road cars had a reported of power and of torque. One of these is not for sale and has remained within Holden's concept car collection. In April 2008, the other road car was sold to the Cairns car collector, Shawn Ryan. It has since been inaccurately stated in the media that he paid the record-breaking price of A$920,000, making it the most expensive Australian car ever sold. In reality, however, the quoted price tag was for both an HRT 427 and the first HSV VS GTS-R ever built. The portion of that figure attributable to the HRT 427 is $710,000, which was the amount the then owner received before commission to the sales agent. In June 2010, the concept car was re-sold at auction in Sydney to an anonymous Queensland buyer at the far lower price of A$350,000. The four racing cars have likewise made their way into collections, with their racing careers shortened by regulation changes. The interest in the HRT 427 was such that, in 2008, its spiritual production version became the
HSV W427 sedan built to celebrate HSV's 20th anniversary. In addition, in 2004, a more affordable racing coupé version reemerged in the form of the
HSV GTS-R.
2004 Convertible The Holden Monaro four-seater convertible, codenamed
Marilyn, was a fully operational one-off concept car, it was never intended to reach production. It was built in 2002 in
left hand drive by
TWR Engineering at a reported cost of A$2 million and shown at the 2004
Sydney Motor Show.
2004 HSV GTS-R The HSV GTS-R concept car, codenamed
P120, was unveiled at the 2004
Sydney Motor Show. Similarities could be drawn with the HRT 427, however, the GTS-R was never intended for road-use but for a one-make racing series. Its more aggressive appearance was achieved through the use of a large front airdam,
xenon headlights,
LED rear lights, active
carbon fiber rear spoiler and rear diffuser. The GTS-R was powered by a modified version of Chevrolet's LS2 V8 engine rated at . Other features included carbon ceramic disc brakes, rollcage, side-exiting exhausts and 19-inch ROH alloy wheels. The concept never reached production. but never reached production.
2013 VF project In 2013, the Australian media became aware of a "VF Monaro" digital rendering posted online by design firm, Dsine International, which also saw the input of Holden designers, Simon Gow and Peter Hughes. It remained only a rendering with no production prospects, thanks to the existence, at that time, of the larger volume selling fifth-generation
Chevrolet Camaro, which was based on the same
Zeta platform of the
VE-VF Commodore. == Motorsport ==
