Ok, we've no idea how to call this one, but there's some discussion going on over at GMInsideNews as well as Automochatter about whether or not that picture you see above is a powertrain mule for the new Chevy Camaro. The photo shows what looks to be a Holden Commodore with some bolted on fender flares that's lost a couple of inches from the wheelbase. And since, as one commenter on Automochatter claims:
"The Camaro will lose 2.xx inches in wheelbase compared to the Commodore. The mods made to the C-pillar and rear doors look about right to accommodate that to me."
