I assume that the tunnel, which is situated in the middle of the rear floor is for the exhaust system?

It's a pity that the floor cannot be flat, and the exhaust pipes some how re routed.

I agree it would be great to have a flat rear floor but next time you are getting into your car take a quick look underneath to settle your curiosity.

The ix20 has a flat rear floor

The tunnel adds a large amount of strength to the floor pan.

Sorry for the late reply.  New member catching up on earlier threads.

I'd never noticed that their was a tunnel actually.  Have to have a look tomorrow.

the tunnel in the floor provides strength, and adds to the rigidity of the vehicle.   a flat floor will flex and bend far more easily than one with a curve in it.

Also, if you have a fragile bag that might slide around in the boot, the floor of one of the rear seats is a nice size to contain the item without it getting hurt.

The hatch has bag handles (one either side of the hatch space). 

I agree with what others have said, it is more about strengthening the floor pan by putting a "tunnel" in it, than a place to route the exhaust pipe.  Try it with a bit of paper (i.e. make it look like the floor plan with a tunnel, then try and bend it).

Corrugated cardboard and roofing work using the same principle.

Wow, I totally had not noticed those there before!  Nice little feature.
