A new supercar is in the works but have no fear, this time it won’t just be another fiberglass body draped over a makeshift chassis and force-fed LS engine. This new supercar will serve as the replacement for the awesome Ferrari 599 GTB Fiorano, and it’s expected to go on sale late next year as a 2013 model, possibly with a showing at the 2012 Geneva Motor Show in March.



These are the first spy shots of a test-mule for the new Ferrari supercar (note, a video of the test-mule already exists), revealing a makeshift 599 body wrapped around what’s believed to a brand new chassis, though some commonality with the 2012 Ferrari FF will be present.



We can clearly see the modified bumpers and temporary Ferrari California headlights but look a little closer and you’ll notice that the bonnet has actually been modified slightly, especially near the front, while at the rear the exhaust tips look to be sitting higher than on the 599.



Despite talk about twin-turbo V-8s and HY-KERS hybrid systems, Ferrari’s popular grand-tourer is expected to feature a more potent version of the direct injected 6.3-liter V-12 engine found in the FF, possibly with as much as 700 horsepower on tap.



And you won’t have to worry about a complicated all-wheel drive system weighing you down like in the FF as the 599 successor is expected to remain rear-wheel drive, though it will likely get Ferrari's latest seven-speed dual clutch gearbox.



Aluminum will also remain largely in its construction as full carbon fiber has been ruled out due to economic constraints. There will still be plenty of innovative lightweight construction techniques and you can bet some carbon fiber will be used for many of the car’s components.



One major difference is that the 599 is now grouped under Ferrari’s sports car portfolio (458, 599 and Enzo replacement) and not the automaker’s grand tourer group (California and FF), so expect its replacement to be much more performance-focused.

Stay tuned as we’ll keep you updated as information on the 2013 Ferrari 599 replacement breaks.
