They could give the base model Grandsport "like" styling minus the actual badges.
The question is will the ZR1 (the king) return in the C7?
Would they drop one out of the three (Z06, Grandsport or ZR1)? If you make the base model Grandsport like styling the marketing would be muddy. Maybe they would drop the Z06. It had a 8 plus year run.
C7 Base "Grandsport like styling minus badge" 5.5 litre HP about 430 HP
C7 Grandsport 505 hp. 5.5 litre supercharged
C7 Z06 505 HP LS7
C7 ZR1 638 HP LS9
I think the base model should be just that. Focus on maximum HP, performance, and handling, while keeping cost down with less creature comforts (other than some minimum level of computer that ALL modern cars will have), less GS-like styling, no wide body, etc. No need for more HP than the current C6, imo.
No more LS engines after MY 2013. On to the Gen V small block for the C7, with DI and a higher compression ratio. More bang for the buck. With my limited marketing mentality, I say Chevy should make it an attainable next step-up from the Camaro. Keep it under $50K, if possible.
Just for reference, here are the 2012 production numbers (
National Corvette Museum: 2012 Corvette Production Numbers Released):
24.2% base coupes
5.3% base convertibles
43.4% GS coupes
19.5% GS convertibles
4.1% Z06
3.5% ZRs

11,647 total
With these numbers in mind, next generation hype should be sufficient for high sales (maybe I should say "good" instead) of a base model coupe for MY 2014. The base model vert didn't seem overly popular for 2012, although the GS vert did quite well. So, who knows what Chevy's thinking will be regarding rolling out the convertible C7. It will be interesting to see the impact of the awesome 427 convertible on production and sales numbers, and how that affects Chevy's thinking going forward.
I don't see how Chevy could wait any longer than MY 2015 to introduce the GS and GS vert, which made up 62.9% of MY 2012 production. I don't think the GS needs additional HP to set it apart from the base model. As is the case with the C6, better styling (I love the "shark" vertical vents), badging, and of course, better handling & performance would keep GS buyers feeling they had purchased something special. And, a wider body will accomodate, well... wider bodies, perhaps making the GS the preferred package for Boomers and older Gen X types, while the smaller, more affordable, base model appeals to the younger crowd?
The ZR1, which would logically be the last C7 introduced, is the one that might seem at risk. But, Chevy needs the ZR1 brand for prestige, and in order to compete on the world stage. Although, the Z06 is certainly no slouch in that department. Maybe it's the Z06 that would go away? Barely more production numbers in 2012 than the ZR1. Did Chevy make enough money from the Z06? I want my next Corvette to be a Z06, so I hope it doesn't go away!
