Australian enthusiast magazine Street Commodores believes HSV is developing a new version of the GTS-R, and has suggested there may be a supercharged engine sitting under the bonnet.
The reports say a development vehicle has been spotted around Clayton in Melbourne.
The magazine says performance suppliers have confirmed the existence of the vehicle, which reportedly features carbon inserts and the brand’s Hazard Yellow paint.
The magazine has no confirmation of the rumoured GTS-R’s powerplant, but says the engine sounds supercharged and could potentially be version of the high performance LS9 V8 used in the Chevrolet Corvette.
The rumours should be taken with a grain of salt, however, with incorrect reports of an E-Series GTS-R been circulating for years.
Last year, HSV managing director, Phil Harding, described one report on the GTS-R as “pure fantasy”.
Speaking with CarAdvice today, HSV spokesman Tim Jackson refused to be drawn on the potential of a new GTS-R, enforcing the company’s policy of not talking about future products.
On the topic of whether there would be a surprise in HSV’s line-up at the Australian International Motor Show in Melbourne in July, Mr Jackson was similarly tight-lipped.
“I wouldn’t tell you if there was or wasn’t,” Mr Jackson said.
“We’d prefer to keep the surprise for then.”
Whether the rumours are just those, or whether there is a little more substance behind the claims of a supercharged HSV GTS-R halo car, only time will tell. We’ll keep you posted if and when we hear more.
