C6-Renesis
I wonder if GM ever toyed with the thought of a Z06 with say a 2 liter or so Renesis engine to get a nice high HP- low weight Vette.
Yes I understand they'd have to buy the rights etc. But the weight saving is interesting.

Re: C6-Renesis (Springman)
What the...? 
The C5 was was already a lightweight compared to the best of the rest of the world. C5 owners always wanted Z06 power in a targa or convertible, and they're getting it in the C6. No reason to go wacky with a Wankel, you ******!

What weight savings? The LS-6 engine is 25lb lighter than the 13-B REW was. Assuming the Renesis is 75lb lighter than the 13B-REW (elimination of all the turbo plumbing), then you save 50lb. You also have only 250HP versus 400HP and 160 ft/lb torque versus 400ft/lb.
Why on earth would GM ruin the Corvette like that?

Plus, the LS2 is even lighter than the LS6 by 15 lbs., as I recall.

Re: C6-Renesis (Rogue Wave)
Nahhhh.
I did hear from a source that at one time it was considered. The source should know. He also told me that in the past they considered everything known to man and as usual common sense prevails.
No doubt in my mind that someone else is riding around it one- I'm told in fact that is true.

Re: C6-Renesis (Springman)
That would have to be a 3-rotor (a 20B Renesis). The 20B as used in the cosmo, weighs in at a whopping 489lb, due to the heavy center cast iron plate. Again not a practical solution either from a weight, packaging, or power output (400HP at best) standpoint. That is why it was never used in the FD (3rd Gen RX-7).
Mazda has done extensive research of larger 2-rotor displacements, and the largest practical size would be 1.4L. Beyond that, the odd shape of the combustion chamber created by a larger rotor would make that engine incapable of meeting fuel economy, emissions, or power goals, offsetting the effect of the larger displacement. The combustion chamber shape created by the 13B rotors is the optimal shape for the foregoing objectives. That is why it has been in use since 1971.
