Another interesting thing I didn't notice before:
The engine before the A25A-FKS and the one after it look identical - just like the two V8s look identical. So if they're going to be derivatives of the same block/basic design, that leads me to believe the engine between the V35A-FTS and A25A-FKS will indeed be a four cylinder (which just confirms the rumors, basically).
Could it be that the engine between the 2.0L M20A-FKS and 2.5L A25A-FKS is a new 2.0L turbo I4, and the engine between the A25A-FKS and the V35A-FTS is a 2.5L turbo I4? Does anyone know how the arrangement on this chart is determined - is it by displacement or power? It seems to be displacement, which means that the rumored 2.4L turbo I4 could also be the engine between the A25A-FKS and M20A-FKS, which puts us back to wondering what the engine is between A25A-FKS and V35A-FTS.
My assumption is those two new engines are a new 2.0L turbo I4 (between M20A and A25A) and a new 2.5L turbo I4 (between A25A and V35A).
