Its going to be difficult for the domestic car makers (or any car manufacturer selling cars in the US) to maintain any number of engines that go against the upcoming fleet average of 35 mpg. For the cars that do not meet the requirement, a company will have to buffer them with the majority of the fleet that can meet or exceed the 35mpg benchmark. This fact will dictate that all engine offerings will need to be more fuel efficient, and as the mpg requirement becomes more stringent (by the next decade), IMO it is almost a certainty that the engines will have to be smaller and more fuel efficient. In a nutshell......the future v8s that are left may be smaller than what's being offered now.
