I don't have a clue how to take photos and post them but, our 2020 Rav 4 XLE with 27,342
miles on it is averaging 33 - 34 mpg on the highway. Not sure about in town driving though.
 
My 2014 Mazda 3 has about 48k miles on it. The best I can do driving carefully in stop and go traffic around town (worst case conditions) is 29 mpg. On the freeway under best case conditions I get 40 mpg if I take the bike rack off the roof and keep it under 75 mph. Just having the bike rack on the roof, without any bikes on it, drops freeway mileage significantly down to around 33 and worse if there's a bike on it.
This matches the factory quoted EPA mileage.
Note: the Racing Beat tuned exhaust I installed a few months ago adds a small marginal boost to torque, power and efficiency. More on that here.
Also, using 92 octane gas (which the car does not require) seems to provide a small marginal increase in efficiency. Smaller than the difference in fuel price, so not worth it.
