The Ferrari 599 Gran Turismo Omologato - or something that everyone has given that moniker to - has been snapped in varicolored glory outside the Ferrari factory in Maranello. Taking turns in red-and-black, blue and black the car is disguised in the same way as the previous surreptitiously-caught 599 that everyone wants to be a GTO.

A keen spotter on Teamspeed even pointed out the fact that the tape over the rear bumper appears to be hiding vents as on the original GTO. Otherwise, save for the black roof and diffuser, things don’t look like they’ll change much if this is anything close to the final version.

Ferrari is reportedly currently working on the three V12 cars that will replace its comparable current offerings: the 612 Scaglietti, 599 GTB, and Enzo. The 612’s follow-on will be the first one to arrive, likely in early 2012, and another mule has been spotted out and about. It still sports the hood scoop (bigger engine with more power, anyone?) and California-style stacked tailpipes, and it looks like it might have a longer wheelbase to boot.

Rumor has it that the new direct-injected V12 will be 40 percent less polluting and get 40 percent better gas mileage than the 5.7-liter V12 presently in use, even as it’s expected to get a slight 7-horsepower bump to 540. The fuel economy increase would provide a very respectable 16 MPG - not bad for a car that ought to hustle to 60 MPH in about 4.5 seconds. Check out a host of new spy photos in our gallery below. In case you’re curious, the sticker on the steering wheel boss which reads “Betrieb nur mit geschlossener Motorhaube” is an instruction telling drivers that the engine should only be started with the hood closed.
