Funked I've seen similar 4WD cars like that Geo Tracker humiliating bigger "real" 4WD cars like Chevy Blazer, Dodge Ram, and Jeep Cherokee in OffRoad races.
They're small, can drive slalom between the trees, they're light so they don't sink in to the swamp so easily.
In some cases slightly modified small Suzuki 4wd is really better option than some larger, heavier offroad machine.

With better 4WD you just find yourself from deeper swamp.
