This is like saying if you go back 10 years, computers still had RAM, hard drives, CPUs, and GPUs so they're basically the same as today while neglecting the fact that there have been significant improvements in all of those and a modern computer would run circles around one from 2009.

There aren't many noticeable improvements in cars from one year to the next, but over the span of a full model change, you usually get fairly significant improvements in safety, fuel efficiency per horsepower, and in-cabin features.

Also note that we haven't reached maximum ICE performance yet, either. For example, Mazda is soon to release their Skyactiv-X engine, which is a sort of hybrid spark and compression ignition system with a large fuel efficiency increase over traditional engines.
