Instead of just a chop-top treatment with a targa bar, this R8 gets fully reworked sheet metal from the A-pillars rearward. The signature side blades have been removed completely, as well as the pillar-mounted fuel-filler door. The engineers also have used a clever soft cover to give the appearance of a simpler setup at first glance.
Upon closer examination of the spy photos, it appears as though this R8 has a full convertible conversion similar to that of the Lamborghini Gallardo Spyder. The rear sail panels most likely lift and fold out of the way, while the engine cover flips rearward to make way for the folding roof. Once everything is stored, the engine cover flips back down over the folded top to give the R8 a clean, uncluttered appearance with the top down.
