Remember, it's not just Cd that counts. Cd times A (A=frontal area) is the thing if you want to compare apples to apples.
The GM likely has higher A than the Toyota. So all else being equal (which it's not - the Previa has a 4-cyl and is lighter) ... but just hypothetically, even with the same Cd, the Toyota would have less drag because of its smaller A.
