2004.5 S40 T5 / 114k Miles / No Mods

Ran straight off an 8 inch curb, hit the bottom of my car, kept driving. Seemed just fine. Drove the 200 miles back home, got terrible gas mileage the whole way after running of the curb.

Filled tank up halfway, screen read "310 Miles to Empty Tank".

65 miles of driving later, screen reads "145 Miles to Empty Tank".

Gas amount drops by 10 miles (165 miles down to 155 miles to empty) every time I really get the engine moving, (e.g. Taking off from a red light, 45mph-65mph passing on the highway, and 20mph-40mph jumps in town). Driving slowly, gas amount stays constant.

What the heck did I damage and how do I fix it guys?

Alignment, pinched exhaust, flat tire........ If the CEL is on, O2 sensor.

Tires are fine. No CEL. Is a pinched exhaust when it is dented, or what? I'll check out alignment.

Maybe damage to the top of the gas tank causing it to seep out but not really leak. Can you smell gas?

I would put it on some ramps and take a look
+1 Why ask? Take a look. ;)
If this is a guessing game I'm going with smashed/pinched/dented exhaust. This is classic in MN. People back into a frozen snow bank & kink the tailpipe.

Step 1 - find pinch in exhaust
Step 2 - replace pinched portion with new, unpinched pipe
Step 3 - drive and enjoy :)

Before you go around asking you really should check it out yourself, or if you're inexperienced or have no idea, take it to a shop. It's hard for us to guess when we can't see. Good luck!!
