We can see some of you scratching your heads over this choice, because the C8.R isn't a production car. It's what you can't see under the bodywork, however, that grabs our attention here. Only one other model in Corvette history brandished a DOHC V8 – the epic C4 ZR-1 that went away in 1995 – but the high-revving mill returns with a vengeance for the C8 and the C8.R dishes up a delectable flat-plane-crank preview of what's to come for production models. We still don't know for sure just how deep the DOHC rabbit hole goes, but from what we've heard thus far, we can't wait to tumble into the void and get lost in ear-shrieking V8 wonderland.
