1.8L vs 5.7L

Pretty sure part of it is due to lower idle RPM. Want to say these trucks idle at 5-600rpm, Prius engine idles at 1000rpm. My Insight burns about 0.2 gph with its 3 cylinder, which needs to idle at 900rpm minimum to not rattle your teeth out - and without the hybrid system smoothing out it's still a very rough idle.
Twice the cylinders and marginally larger cylinders, but half the RPM, still twice the fuel consumption.
