HSV is in final countdown to launch LPG versions of its hot Holden Commodores.
LPG HSVs will use the latest liquid injection systems to wring maximum performance from minimum fuel.
Maintaining power output similar to the petrol V8s is critical if the liquid gas is to succeed in the high-performance
models.
They'll be on sale early next year as part of the facelifted V8 E Series 2 range.
An LPG-powered car would give HSV an advantage over rival Ford Performance Vehicles (FPV), a spokesman for which has said there were no immediate plans to introduce a gas-powered version of either its turbocharged inline six-cylinder models or Boss V8 range.
Earlier, HSV chief engineer Joel Stoddart said LPG technology has moved well beyond the stigma of taxi fleets and funny smells.
We are seeing performance figures comparable to our 317kW LS3-powered range and it has certainly bought a smile to the face of the engineers testing the technology when they pull into a service station and can fill up for around A$20 ($24), he said.
Another advantage was a range of up to 1000km, due to dual-fuel capabilities.
HSV announced a year ago it was testing various alternative-fuel prototypes running LPG, E85 ethanol blend and diesel. However, it's now confirmed a diesel product programme will not proceed.
HSV is also working on developing a high-performance version of the forthcoming Australian-built Cruze as a replacement for the discontinued Opel-sourced Astra VXR.
It's likely to be powered by one of GM's new breed of small-displacement direct-injection turbocharged engines.
