i.e. should have read like this:
"Chevrolet unveils to the world the Chevrolet Corvette Z06
, Convertible
, and its new Monte Carlo coupe."
However, why would the C6 convertible be unveiled at the 2005 auto show when the vert is already out in the public (Car and Driver tested a C6 coupe and a C6 Convertible a couple months ago)??? Hmmm... perhaps there is something to the original statement! Here's a hypothesis, bear with me as I'm conjouring this as I write.
The "Blue Devil" is rumored at 500HP, the Blue Devil is NOT the next Z06. The current (C5) Z06 is 405HP, the base C6 is 400HP. Z06 would then have to fall between C6 and "Blue Devil". How do you make the Z06 a "better" car without out gunning a 6-digit super Corvette? Answer, you add 50 ponies and a drop top option, preferably with a retractible hard top to maintain rigidity and safety on the track, and an obvious and distinct look from a standard Corvette on the streat. The equation gives a slightly higher performance car than the base Corvette, broadens the market for the Z06 to people like me who want absolute performance but also enjoy top down cruising but can only afford one Corvette, while at the same time leaving the niche market for the "Blue Devil" open for people who want something truly unique that is the absolute top end performance car (previously Z06) from Corvette.
Just my random thoughts... but it's a crazy world, and you just never know!
