Sebring 2008The raised nose has become a common feature (if somewhat aesthetically controversial) among contemporary LMPs.  Doing so frees up additional splitter area and improves airflow over the top of the diffuser.  The small duct in the nose presumably helps draw cooling air into the footwell and the mechanical components located there. 
WDWT, Sebring 2008The 908's front diffuser shows a rather aggressive center section with only two longitudinal strakes (one either side).  The yellow highlights show the height difference between the top of the splitter and the bottom edge of the diffuser.  That they don't come to a common trailing edge is worthy of noting and is a primary difference between this solution and the Audi R10's. 
Sebring 2008The entire nose/diffuser quick-releases off in seconds allowing for very rapid replacement and access to the front suspension.
Sebring 2008The shutter panels are for regulations compliance and cover the suspension and underfloor from view brining the bodywork in that area up to at least 200 mm in height from the reference plane (the height bumps up to 400 mm once past the cockpit opening).
Sebring 2008Within the valley between the front fender and the monocoque is a turning vane that is attached to the inner fender.
Sebring 2008At Sebring twin sets of dive planes with outboard gurney "endplates" were utilized.
Sebring 2008A full set of front fender louvers also augmented the need for more front grip in the face of higher total downforce levels being used at Sebring.
