Watch: Is This the PHEV C8? by Evan Williams August 29, 2019 Share Comments Are there new versions of the C8 Corvette out for testing already? The TFLcar YouTube team went exploring in the mountains of Colorado looking for prototypes and they seem to have found some C8s. But look more closely and these camo’d C8s have electrical plugs sticking out of the hoods. And the shielding on them looks to be bright orange. Which means high voltage power. So are these upcoming C8 PHEV prototypes? Maybe. That’s a pretty strange electrical connector if they want to charge the cars anywhere. In any case, watch the clip and get a good look. At least the one car is hiding what could be a new headlight design too.
