The fuel economy of the 2.4L Chrysler 200 with 6 speed auto is 20 city and 31 hwy. the 3.6L Chrysler 200 with same transmission is 19 city and 29 hwy. why such a small difference?

Because if the size and weight of the car, the little 4 cylinder has to work harder to move it. RPMs = fuel consumption. The 6 has more power and
runs at lower RPMs so they almost balance out. With that difference I don't know why anyone would buy the 4. Not worth it to save $10 on the one or two spark plug changes over the life of it.
Small engine doesn't always mean better mpg. It's about a balance of gearing and power, and how they relate to NORMAL driving. Not what the EPA thinks is normal.
The 200 you might just cruise up on the highway going no higher then 3k rpms.
Same car smaller engine you may have to rev out to 5500 to get the same acceleration.
That's revs per minute. So 3,000 x 6 cylinders equals 18k times the injectors fired, and they fired at a lower fueling schedule not hitting peak power.
Now 5500 x 4 cylinders equals 22,000 times the injectors fired. Also they fire at peak or near peak performance so potentially using more fuel.
It's about a good balance in a car. Did you ever see the top gear video where a 300+ BMW M3 got better fuel mileage then a Prius.
I personally in a 2001 Corvette got low to mid 30s mpg on the highway. Reason being low drag coefficient, the gearing had me at like 700 rpm at about 70ish. That is almost idling. The Corvette has enough low end torque to move all of this easily.

I'm detecting a little exaggeration on this part of your post or miss typing.
Is it a heavier engine? It may be the same engine with different pistons.

ON THE OTHER TOPIC:
In my 1995 Camaro Z28 I get around 26-27 highway. That is because it has an extremely high overdrive gear ratio. In the City I get anywhere from 8-15 depending on how I drive. It is a huge difference.
I can see the corvette doing better, it is much lighter and more aerodynamic.

I'm thinking it was a typo. I know for a fact a manual trans, non-performance rear ratio Corvette with standard tire sizes of that vintage is turning around 1,700 RPM at 70mph.

No... 6-speed ls1 on the highway. Look around on the web wouldn't be the only one.
Same car ran 13.2 with like a 2.4 or something 60 ft. It was my dad's trip was from Orlando to ft. Lauderdale. My dad told me it did that on the highway of you take ot easy on the highway. I didn't believe him.
Don't worry in the city around 20 mpg, and when you romped on it, much worse.
His 07 isn't as good on the mileage.
