The HSV GTSR W1 - History In The Making

As a final, explosive swan-song for Holden Special Vehicles (HSV) and its final iterations of specialist performance packages, the most powerful HSV’s ever will be launched from their Clayton base. Enter the GTSR and GTSR W1. Many will be familiar with the GTSR badge, which last made an appearance on the eye-catching yellow and somewhat polarising VS GTSR in 1996. After 30 years working with Holden it seems only fitting that HSV have revived the GTSR moniker turning up the wick to modify these jaw-dropping GTSR creations, culminating in what is Australia’s most powerful Aussie production car ever, the W1. No stone has been left unturned in the process of transforming the car into a modern, mechanical work of art. At the heart of the W1 is a heaving beast in the form of the hand built, 6.2L, supercharged LS9, Gen IV alloy V8. Originally the powerplant for Corvette in the U.S, HSV had to widen the track and front guards to shoehorn the V8 into the Holden. And we are glad they did! To protect the strengthened internals and suit the demands the engine will be placed under, a nine plate air-to-water cooled dry sump lubrication system is employed, which is normally a feature reserved for racing machinery and supercars. To suit Australian conditions, a beefed up cooling system was included, as was a larger supercharger intercooler and hi-flow water pump. The GTSR W1 displaces a massive total of 474kw/+815Nm of tyre destroying power. HSV claim the W1 will hit 0-100km/h in 4.2 seconds and reel off the quarter mile time in an impressive 12.1 seconds, making it the fastest production car ever produced in Australia, adding another title to its long list. If you are keen, for the record, you can also hit 98.5km/h in first gear. In what some would say true ‘purist’ spirit, the new GTSR range is only offered in 6 speed close ratio manual format. Although no automatic option may put a few potential buyers off, HSV’s philosophy of building a road registered race car aligns with their choice to favour a manual. And with manual transmissions becoming rarer each year, and the car’s potential as an investment platform in the future, going manual is another smart decision by HSV on this front we believe. The bespoke list of modifications is truly incredible, many only produced with the W1. There is an OTR carbon fibre cold air intake, custom gearbox input shaft and gearset, single piece forged flywheel, AP racing six piston calipers, specially designed rotors for cooling, 20” wheels that maximise cooling to the brakes and wheels are wrapped in Pirelli P Zero Trofeo semi-slicks. With handling such a critical component of connecting the driver to the road, HSV’s ultimate creation has an all-new Supashock suspension system, modelled off Walkinshaw Racing’s Supercars. Combined with the HSV enhanced Driver Interface (EDI) a full range of electronic based drive characteristics can be optimised to your preference, including torque vectoring, stability settings, launch control, bi-modal exhaust and electrical steering weight. The end result of all of these individual changes is a package that is more than the sum of its parts and something HSV and the Australian automotive market should be proud of. It represents what can be accomplished from Australian based manufacturers, providing a ray of sunshine in what is otherwise a somewhat glum period for Australian manufacturing and automotive market.   Keen to get your hands on this piece of Aussie automotive history in the making? Unfortunately you are already too late. Once word got around of the impending launch of this incredible machine and the fact only 300 W1’s are ever being produced, orders flooded in, resulting in the car being sold out before it even hit the showroom floor. In fact, more than 500 additional orders were unable to be fulfilled, leaving many potential owners disappointed they would miss out. Of course all this performance, exclusivity will come at a cost. How much? Well you won’t get any change out of $170,000. That may seem like a hell of a lot of money, but given its status as the most powerful HSV ever, the fastest production car ever built in Australia, the most technologically advanced HSV, and the final Holden HSV to ever be built, there are more than a few reasons to join history. Will the HSV GTSR W1 become the next GTHO Phase III in the future, or is it overpriced for what it is? Let us know on the Rare Spares Facebook page.

Roaring Heart – The Aussie Powered Alfa

In 1986 Paul Helstead and Formula 1 engineer Barry Lock set about building one of Australia’s first supercars; a rear-wheel drive Alfa Romeo Sprint. The initial plan was to pair the Sprint body with a mid-mounted 2.5 litre Alfa Romeo V6, coupled with a ZF 5-speed transmission and Brembo brakes. This hot coupe was to be named ‘Giocattolo’, which translates in Italian to ‘toy’. Shortly after testing began, the Giocattolo team was to face issues in guaranteeing a steady supply of engines from Alfa Romeo, thus the search began for a replacement power source. Halstead and Lock were to eventually decide on the Holden Walkinshaw 5.0 litre V8 Group A engine as the new power plant. Producing 220Kw/500Nm, the new engine package was a rocket, capable of powering the Giocattolo to 0-100kph in just 5.4 seconds, whilst having an electronically limited top speed of 250kph. As a result of the upgraded tires, brakes, transmission and a high tech Formula 1 style rear suspension setup, the Giocatollo possessed handling characteristics not dissimilar to a road registered go-kart on steroids. The interior of the Sprint was also modified in the Giocattollo build process. The standard seats were replaced with leather Recaro’s, a Momo steering wheel was added and the dash was modified to fit the extra gauges. Other interesting features were the new centre console with integrated handbrake lever, power windows, air conditioning and even central locking. As a result of the $80,000AU price tag, the Giocattolo did not sell particularly well, with only 15 of the Italian-Australian supercars were built, including 3 prototypes. In 1989 the Giocattollo closed its doors after 3 years of production, finding that it was not the right time for such a car in the Australian market. Of the 15 built, car number 007 was destroyed in an accident in 2001, whilst one other is unaccounted for. Car number 007 was originally owned by the Brisbane Bears Australian Rules Football Club and was painted in the club’s colours; with a gold exterior and maroon interior. Car number 011 is also believed to have been owned by Lindsay Fox at one point in time, whilst the Queensland Police were even considering using Giocattolo as their pursuit car! All known remaining cars are reported to be in great condition and have been known to change hands for well over the original $80,000 price tag. What is your favourite uniquely Australian car?
