While I have not read Dave's book I did read ACAR several times and also the GM C6 book that was putout around SOP. Autoweek is a secondary source and should always be questioned. Look at how many times a partial quote has been expanded to mean something 100% different, the Zeta on hold thing for example. The C4 represented the greatest threat to Corvette in its history. The car was old, outdated and ran WAY to long. Many higher ups wanted GM to be FWD unibody cars and Trucks/SUVs. If not for the dedication of the Corvette team and creative accounting the C5 would never have happened. That being said GM never thought to kill it seriously.
Also being on hold pending financial approval is not even close to being canceled. Almost every program is put on hold at some point. It is the time at which the bean counters examine the business case and decide if it will be profitable enough to do or if the business case needs to be redone.
You gotta link to this or are you going from memory. Without seeing the exact quote I can't speculate on what it said but I doubt seriously that Corvette was ever in jeopardy.
Sure the Corvette guys didn't want to share their platform, the original idea for XLR to ride on a modified Sigma didn't pan out, and so the suits said this is how it is going to be. But you know what the extra funds that the XLR program provided to the C6 development benefited Corvette. XLR didn't take away funds it added funds. The C6 business case would have been made on its own without XLR if need be.
The Kappa cars have a completely different business case. The LOW cost $19,999 base Solstice was going to be unprofitable based on its projected volume so the Saturn version (shared w/ Opel et al) was added to spread the costs out to make the cheap base Solstices at least doable if not profitable.
But Corvette isn't a low volume car at a cheap price. It is a low volume car at a high price. There is not much materials cost difference b/t the Kappa and Y body chassis. The powertrain adds cost and so do options but overall the price increase is justified by the performance of the Corvette vs the Kappa cars.
I never saw said V6 concept and I doubt it had a brand name or model name attatched to it. The car if it existed was likely nothing more than an engineering mule.
What is the name of the book? I may have to add it to my collection. But as for reading it now, not enough time. Barely enough time to get on C&G at all 32 credit hours this semester will do that to yah!
