Yes, the 2.0 six makes no sense over a four cylinder, 2.0 is an ideal capacity for a four banger. But then you can "brag" about having a six cylinder car, people will be fooled. Even more crazy is sub 2.0 sixes, both Ford, Mitsubishi and Mazda have had 1.8 V6 engines. It sounds cool, but in engine design any six under 2.5 capacity makes no sense.

Not to discount anything you said here, but there is also an element of ‘teaching for the test’. When agencies set to measure the mileage rating that ends up in advertising, they do it in a way that often diverges from how an actual human driver behaves. A smaller engine uses less fuel than a larger one when it’s left to its task of reaching a certain speed or RPM. Most drivers will not accept simply accelerating slower than the traffic around them, and will wring the smaller engine out past its peak efficiency.
