Drag coefficient

I was compairing different car's and their Cd. From reading about boat tails and the streamlining template on this forum i expected that most cars that have a clean body with a small angle taper at the back will have a better Cd than cars that are hatchbacks.

The following cars/truck have a suprisingly low Cd.

2008 Chevrolet Tahoe Hybrid Cd. .34
2010 Ford Escape Cd. .29
2005 Honda Odyssey Cd. .30

How can such a huge vehicle that has the opposite of a boat tail be better than most small, fuel efficient cars with a Cd. of about .35? If they can lower the drag on these big SUV's without a boattail, then what's making them better than sports cars from the 90's?
