Cameras located in the vehicle's grille capture data used to feed a Head-Up Display, effectively creating a 'see-through' view of the terrain through the bonnet and engine bay, breaking new ground in visual driver assistance.
There's a film on their website showing the device in action, and a short animated-GIF here: http://i.imgur.com/izwI6Fl.gifv (not sure how long the gif will be available).
Basically the device gives you a view through the engine compartment when you are driving through rough terrain. I can see this being really handy for navigating off-road.
