G8 GT...
Got to play with a G8 GT this morning... results were not exactly as expected.
I was headed down a two lane highway when I noticed a black car flying up on me. As I checked the rearview I noticed the hood and knew it was a G8... wasn't sure what model yet but I was able to tell shortly after.
Seconds after flying up the G8 jumped out and passed... as it rolled past I could hear the exhaust and saw the GT badge on the rear deck. Wasn't really sure what to expect from these as they have 360ish HP but are a bit heavier than I am. From highway speeds I figured it would be interesting so I followed close just to see what was going to happen. Soon enough a car slowed to turn off the highway and left me and the G8 all alone from a slow roll to feel each other out. I saw a quick puff of black and the rear slightly drop on the G8 and I quickly went WOT behind. We went from a casual 25mph to 80mph and by that time I had pulled right up on it's bumper and let off.. the G8 stayed in it a bit longer and put some distance between us before slowing down.
After the next small town the 2 lane jumps to a 4 lane highway and I was eagerly awaiting the event. I caught back up and hung close behind the G8 as we made our way to the split. We were sitting in a 45mph zone moving along and when the speed limit went up and lanes split sure enough I see another puff of black and a squat. I quickly dropped to 2nd and signaled for the left lane, after the previous squirmish I had an idea of what was going to happen next. By the top of 2nd I had pulled nearly even and with a nice solid bark into 3rd I started walking right on past pulling quickly ahead and putting some space (maybe a car length) between us before letting off again.
I know the GXP runs similar times (~109traps) and the GTs are not pulling near the same numbers but I was expecting a little more fight from that much power. It was definately fun... I tried to grab a quick video on the Iphone but it proved to be too tricky to coordinate that and shift.
I can't wait to get to the rentals next month and see how the car does... certainly feeling strong.

Our local performance shop just got one of these. Bone stock it ran 13.5 @102. With a CAI and in house tune, it ran 13 flat @105, and picked up nearly 30 rwhp from these 2 mods alone.
Not too bad for a 3800 lb. 4 door family car!

And such is life with GM programming, it's pretty damn restrictive (mostly in the TM department...). I like the G8 GXPs, and honestly if it had been out a couple years earlier one of those would be in my driveway instead of the SRT8 (love my SRT8, but I love the heavy aftermarket for the LS motors better)

nice kill man. after some debate on another forum, i took one for a test drive and was unimpressed. of course i was using the *** brand accelerometer and it didn't seem to pull as hard as i had expected. without actually runing it for times and with the accelerometer out of calibration i can't really say for sure.

I took one of thess G8 GTs on back in april (we were even.. back then my 02 GT was stock). Agreed on the lots of power but bad tune.. plus I think the automatic is kinda crappy. A manual would be lots of fun on the G8 GT... they probably didn't do it because it would be closer to the GXP.
