Reports suggest it will be based on the W427, which means it is very possible it could sport an all-new look when it arrives in the UK in September.
Engineered by Tom Walkinshaw Racing, it is expected to retain the W427 namesake and will carry a price tag of around AUD$117,000 or £55,000 in the local money.
A bespoke suspension setup is also anticipated to suit UK roads, which may include the Magnetic Ride Control system featured on the HSV Clubsport GTS which is currently unavailable in the UK with the VXR8.
With the LS7 V8 engine churning out 370kW and 640Nm, 0-100km/h performance is expected to drop to just 4.5 seconds.
With these figures, the W427 is well and truly a competitor for the Audi RS6, BMW M5 and Mercedes C63 AMG - although this time the price tag does match.
