Speaking of G8s...
GM-Holden have only just recently sealed a deal to
begin exports of the new Commodore (your G8), but marketed under the Chevrolet brand name in the next 18 months.
"... the company did not rule out exports of Chev-badged Holden Utes and Commodore Sportwagons to the US alongside the SS sedan at a later point, with Holden engineering executive director Greg Tyus telling journalists in a phone hook-up from Holden’s Melbourne headquarters: “We are discussing sedan at the current time.”
Here's the current car - the new one should be a lot more sleek. This design is quite elderly on our roads here.
El Camino, anyone?
Looks like they're going to call it "Chevrolet SS" and you'll most likely be able to choose from the LS2 or LS3 that they run around Australia with at the moment.
They'll probably be cheaper than dirt, too. Lots of weight reduction over the existing G8, with many vast improvements, I'm told. Should impact on existing GXP prices once these new VF-based cars start to arrive.
Last report says it will hit US showrooms as a 2014-model in Q3, 2013.
