sorry holdenguy, we use the kaplow system, not the bang system like the rest of the world...

You make valid points and is hard to disagree with you. I guess it doesn't matter to me because if I go for a high performance 4 door car from GM, it will likely be a 09'
CTS-V. I would also be really happy with the 08 CTS.

I think it's something folks on here can appreciate, but on a mass-marketing scale wouldn't happen. I think we might see it more likely in a Buick moniker than a Pontiac.
 
CTS-V is a great car, I just can't justify the cost as a street car and don't have deep enough pockets to justify the cost as a road-race car. I'm still running about a $4000 total investment road race car that's 12 years old.

You guys get fuel so cheap there, I would always be using the maximum bang juice available.

Hmm, well interestingly unless your car is tuned for higher octane, you actually get WORSE performance from a higher octane fuel. The higher the octane the less actual power you get from each explosion.

Where did you hear such a thing like that ???? Not with Delphi's fuel injectors that are in GM vehicles. If you car is set to run on regular it might not be best to run premium all the time in it. Some GM, cars are set up to run on premium but regular is okay but they might not achieve max hp.

Right, if you car is set to run on Premium you should run it, although running on regular will have the ECU dial back your timing and dial back performance, but likely won't injure the car. If your car is set to run on regular you are wasting your money and probably seeing worse milage and performance from higher octane fuel.

Did I miss this... by wale_bate1

in here: G8 production may come here based on demand.
 
"It is highly likely that as we move to higher volumes for the global rear-drive architecture, we will begin to produce" in North America, said GM Vice Chairman Bob Lutz. "Importing from Australia at this point is a transitional phase. It permitted us to get the car quickly and for a minimum of investment."
 
I hope they hit the demand.
 
What I like:
The G8 is 2.1 inches shorter than the Grand Prix, but its wheelbase is 4.3 inches longer, and the vehicle is 3.2 inches wider.
 
So, no more ridiculous overhangs and a car that may actually have as much working space as the exterior implies? All good in my book, and a heck of a step forward for the General!
 
Know what I hate?
 
Waiting...

Well dad said run premium every 10 fill ups to flush the injectors out. My uncle runs 89 mid grade in his pick-ups that require 87. He says he's able to gain about 1 mpg extra. GM's engines you are correct won't gain much power if it's set up to run on regular 87' octane. I however always ran premium in my 02' Cadillac Seville STS and it was fine to run on 87' octane.
