Ferrari has begun testing the replacement for the 599 GTB Fiorano. See the video inside

With Ferrari set to introduce five new models by 2013, it's no surprise the company has begun testing a replacement for the 599 internally known as F152.

Caught at the Fiorano circuit in Italy, the mule is apparently based on the 599 GTO and features LED-infused headlights, modified bumpers, and a revised four-tailpipe exhaust system.

Little else is known, but the car is expected to be launched in 2012. All-wheel drive could be offered, but nothing is official as of yet. Furthermore, a hybrid variant is a possibility but details are slim.
