I think its Mirage. It was a blue indy car in the original, but it fits the modern bill, plus I think his hologram ability would be a cool effect. But I was hoping on a red ZR1 to be Hot Rod.
I like to see Barricade turn into a Challenger and think he he can take BB now witht he upgrade and then get his ass kicked again by BB and oil "pee" on too for good measure. You know..... stick it to Dodge too.
