Ferrari has started work on the successor to its lovely 599 GTB Fiorano. Our spies caught the beast, codenamed the F152, during some warm-weather testing, and although these shots confirm the car's development, they don't really give any useful clues as to what it will look like. Test mules – gotta love 'em.
The bodywork you see here was stuck together from forms for the 599 GTO, and is only there to cover the new car's chassis. The new Prancing Horse is slated to break cover sporting a 700-plus-horsepower 6.3-liter V12 backed by a seven-speed dual-clutch gearbox. Rumor has it that the new Ferrari will also carry direct injection (not surprising). Stay tuned for more, but for now, see the 599 successor mule in our attached high-res image gallery.
