I disagree.
1. GM would never allow a Cadillac to out perform all Corvettes. With 750 HP, this will be a beast that will leave most Euro Exotics in the dust.
2. Maintenance issues. For a while now, GM has required that sellers of Covettes must have GM trained Corvette Mechanics. GM has been designing the C8, unlike the new Ford GT that was partially mechanically designed and manufactured by a third party. Although I have no specific knowledge as to why the Ford GT requires such expensive maintenance, I'm guessing it was this manufacturer, without the mass production knowledge that keeps some focus on service and maintenance, that incorporated the expensive maintenance designs.
3. The new Cadillac Division head has been asked several times about the most important models that need to be added to Cadillac. His political response was that at some point Cad might want to add a two seat sports car to the lineup, but right now there is much greater need for several other models that would be much higher volume than a two seat sports car.
4. Model Positioning. There have been several rumors about how the Corvette model line will use the C8 rear mid. It's anyone's guess at this point.
A. The C7 will continue to be sold side by side in the showroom with the C8 and the market will decide if another front mid will be offered.
B. The C7 will continue to be sold side by side in the showroom with the C8 for a year or two at most. Then other drive trains / engines will begin to be offered (likely at a much lower price than the Exotic Killer opening model.
C. The C7 will die immediately upon release of the C8 rear mid. This scenario would require an "entry" level C8 with something less than the 750HP engine would have ot be offered from day one.
"C." is the most recent rumor, but GM has VAST experience in disseminating mis-information and watching us for reactions.
5. Cost / Pricing assuming it replaces the C7 at introduction: I've stated this before, but lets figure out why a rear mid "must be significantly more expensive" than the front mid.
A. Corvette's current business model has been successful for three generations. Early years of a new Gen sell in the mid 30 thousands and begin to taper down at a rate that dictates when a new gen must be released.
B. Other than the engine block, some transmissions, infotainment and HAVC parts, almost all the parts in today's front mid are unique to Corvette = not shared with any higher volume GM models and most are made of "exotic" light weight materials (Aluminum, Magnesium, composite, and a little carbon fiber)
C. Would a rear mid design require...
1. ...more parts that for some reason would have a costlier design.
2. ...the same number of parts that would cost the same.
3. ...fewer parts that would cost less or mor
One of the points of a rear mid (in addition to Physics) is to reduce weight by reducing the number of parts. If this is achieved and if A. and B. are true - and they are - the only variable from the C5, C6 & C7 might be the volume. If the C8 buisness model assumes it will attain the same level of sales as its predecessors AND if it stays with the mostly composite body (not more costly Carbon Fiber), there is no justification for a significant increase in cost/pricing for the "base" model.
