Some spy video showing a taped-up 599 model recently hit the Interwebs and has left car fanatics wondering what exactly Ferrari is up to. It’s clear that the model is based on the 599 GTO, but it’s not clear exactly what it is.

With the 599 GTB update (codename: F152) on tap for 2012, it could very well be that model. It could also be a prototype of a hybrid 599, either based on the Geneva-launched Hy-Kers concept or a new version.

Whatever it is, it’s fun to watch. Jump the break and have a look. [via Jalopnik]
