We're far far from the end of the performance car. What we're coming to the end of is the days of the naturally aspirated manual transmission performance car. Ten or fifteen years form now there will probably be a 1LE Camaro. And it might be hella fast, making 600hp in the "base" SS model. But, it won't have a non-pressurized V-8. It might have a turbo four with a hybrid system that gives it a torque curve that is unreal and so on, and it might log ten second quarters all day long, but it won't be the same as the jumbo V-8 with a three pedal footwell.
Look at Mercedes. People like to think of BMW as the German performance maker, but MB has been making big V-8 machines forever. The 300SEL 6.3 and 450SEL 6.9 practically invented the "muscle sedan." Other makes have gone back and forth with sixes and eights and so on, but Mercedes has consistently given us giant V-8 engines. Today, we can still get eights from them, but they're all turbo engines, and I bet the days of the turbo eight are waning and we'll see smaller ICEs combined with electrics from them as well.
The writing is all over the wall.
