Well, yes the G8 is a sedan -- try to keep up here, this could get confusing -- and yes, the G8 sport truck concept could be, I suppose, referred to as a pseudo-El Camino.
I'm sure the truck willl do nicely in a straight line and probably OK in the Oval's but when it comes to a full road course I think it will have troubles keeping up. This is just a guess but with most of the weight forward it will negatively effect the handling and in the turns it will get passed by mostly everything.
So if you statement is it will handle well for a truck then I agree, if you say it will handle as well as say a stock first gen V I would tend to disagree.
Let's remember though, F-body cars of the past had a weight distribution pretty close to 60/40, and while they weren't shattering records in the handling department, they were more than competent. My guess is the truck should be in the 60/40 ballpark.
So you say that a WS6 Trans Am had a 60/40 weight distribution? That would be surprising. Hell, the old IROC cars handled fairly well too.
I think an updated El Camino would probably be great for it's utility but I doubt it would be great as any kind of sports car. Any rear suspension that would offer a reasonable degree of "utility" would not be very good as a road car as far as handling, and obviously the opposite is also true. Any setup that would produce good handling and road manners, probably wouldn't be too useful as a work truck. Hence why virtually every sport truck has a VERY limited load rating.
I had a Firebird that I thought handled pretty well after all of the suspension tweaks (New struts, Springs, Pan Hard rod, Upper and Lower control arms, sway bars, shocks...). Was a fun car for sure but it was a bit of a rough ride and with the solid axle it wasn't as good in the turns as the V. Good car for it's time though and it's been a while so I don't remember the ratio but it wasn't ideal. It was a good all around car but it is amazing how much better the suspension is on these newer cars. I drove the V and the comfort was far better then the Firebird and the handling was as well. I have done very little to it so far (sway bars) and wow what a ride.
If they put a little technology into the Pseudo El Camino it should handle fairly well and I wouldn't be surprised a bit if it out handled the old Firebird. Now it won't be much of a hauler if they do that but it should be a fun truck to drive.
F-bodies handled ok. Weight dist and suspension settings aside, it had a rubber chassis. You can tweak a car all you want, but you are only going to improve it so much. Handling begins with the chassis.
Changed mine out to urethene.
Lot a stamped sheet metal stuff you need to get rid of too (excess flex)
I dont like urethane. Sounds too much like urethra.
One works a little better on the suspesion then the other though...
Just to clarify my original comment, and speaking for my own service experiences, I don't find the Cadillac technicians any more or less skilled than the BMW technicians I've had for the prior 10 years. The major (obvious) problems get fixed, but consider yourself lucky if an intermittent problem or rattled gets fixed the first time. On the other hand, every service visit requiring a substantial wait has gotten me into a new Cadillac loaner, the waiting lounge has wi-fi access, flat screen TVs, comfy seats, etc, and the service advisors regularly inquire about my satisfaction.
Sounds like the experience varies greatly across dealers...but somehow the Pontiac experience gives me thoughts of being stuffed in a small room with 50 angry people and a 20year old out-of-order coffee machine... or worse yet, a 3yr old Sunbird or Aztec to drive as a loaner.
I apologize for the large picture, but I thought since we were on the topic, I'd share it. This is the Holden version of the G8 sport truck. The model at the top of the food chain is called an 'SS V'. Notice the similarity of the "V" badge on the tailgate:
