This is not a political statement, though I will mention government policies.
With respect to everyone else's comments and opinions.
Seems to me the current US administration and most of Europe have a policy of ICEs are going away in favor of EVs. So the manufacturers will have to weigh the potential profits during the next decade +. Plenty of time to revive a V8.
However, it would probably be smaller displacement and turbo'd to get efficiency and fuel economy. That will work. Afterall, there have been a number of successful, small displacement V8s prouced in the past. The GM 215 V8 fell to the "bigger is better" race of the 1960s, but stayed alive at Rover for decades.
Supercars/boutique cars are a whole different matter. They're going to get manufactured in relatively small numbers unless blatantly outlawed.
