Motor magazine (Australia), March 2008Since last summer, rumors have swirled in Australia regarding a potential "flagship" HSV GTSR. The original scuttlebutt had GM's Aussie performance division dropping the Corvette Z06's LS7 V8 into one of its fully-tricked, Commodore-based sedans. That never panned out. In the interim, we've seen the introduction of the blown, 620-horsepower, 6.2-liter LS9 V8 in the Corvette ZR1, as well as its less-caffeinated brother, the 550-horsepower LSA, in the Cadillac CTS-V. As such, the time is nigh to commence Round 2 of the HSV GTSR rumormongering. Australia's Motor magazine (no website? come on, guys) steps up to the plate with its March 2008 issue cover shot, a Photoshop of an HSV sedan sporting the ZR1's hood window, with a claim that the LS9 is headed Down Under. Whether the rumor's even remotely valid is anyone's guess, and it's likely to go on for months. You see, something like the mythical GTSR would be a pretty major reveal, worthy of a big stage like the Sydney Motor Show. That doesn't take place until October, so there's plenty of time for this one to get whipped into a frenzy. Thanks to Autoblog (and Motor mag) reader Zayed B. for the photo!

UPDATE: I'm reminded in the comments that the Melbourne Motor Show is less than three weeks away, so perhaps we'll get more word on whether there's a Super HSV in the works sooner rather than later.
