Pondering Motor Vehicle Engines

So, being an engineer, with some mechanical aptitude (not necessarily as in a car mechanic, just for building things) I have been tinkering with the motor vehicles that are available to me lately.
The car that I'm driving here in West Virginia is a 2000 Chrysler Voyager. Not a bad car, though being 6" longer would help quite a bit sometimes. This car has a three liter (3.0l) one hundred forty horse power (140hp) engine. OK, so what, right? Well, the other car that I have is a 1995 Eagle Vision TSI. This car has a three point six liter (3.6l) two hundred fifteen horse power engine (215hp). This means that for a 20% increase in engine displacement (3.0l * 120% = 3.6l) the engine achieves more than a 50% increase (140hp * 150% = 210hp) in output horse power. Clearly the relationship here is vastly non-linear. Should it be? I don't know. All I'm sure of is that the Vision is a lot more fun to drive, and gets the same or better gas mileage than the Voyager.
