I spy.....?

Okay this has been annoying me.

On one of the release photos of the CAT SX you can see under the car (just), in a reflection. It's a light coloured part on the underside. What on earth is this? So far I can think:

1. Simply a plastic under-tray reflecting the white of the surface?
2. A prototype plastic part. (proto parts can be white, before dye is used in production)
3. Photoshopped part like the rest of the photos, reflections been removed?
4. A metallic component? (Schumacher already said the chassis is CF.)
5. Very shiny CF just caught at the right angle to reflect loads of light?

-- What are your thoughts? --

Maybe I'm being impatient and should just wait until next week for the under-the-body photos!
