Well the 2025 target is very achievable considering that Toyota beat that 2025 goal way back in 2011 with the Prius C.
The economic side is trickier. When the rules are set engineers look at it with logic. (Technology to increase fuel economy by X amount costs Y) What they can't factor in is changing consumer tastes and fades 10 years into the future.
Why do Americans buy cars by the pound and believe cost should be related to size?
