Why do they do that? Somebody please tell GM management that there are other letters in the alphabet!

It's capitalising on their heritage. Nobody is complaining about the ZR1 moniker being used three times. :thumb:
I'm just gald that:
1. GM didn't scrap the Corvette when they were bailed out by the US Government, particularly with Obozo's love of "green" energy.
2. It still has good sized 8 cylinder when other manufacturers are going with fewer cylinders, less displacement and turbos.
3. It doesn't have any hybrid technology.

Two different things entirely. ZR1 is a model variant describing a package of performance options, sort of like GT. This is a new engine and IMO deserves a new unique RPO. :thumb:
