RAV 4 is not a big car.
There's many different ways you could think of something as being "big", but in this context I believe either volume, mass or even drag coefficient is what is most relevant to the thread.
RAV4: Cx ~ 0.32, weight ~ 1700 kg
Ford F-150: Cx ~ 0.56, weight: 1900-2500 kg
It's a small car for Americans, and a medium-sized car for Europeans.
