After initial rumors and reports that Ferrari->ke252 would unveil the highly anticipated flagship at the 2013 North American International Auto Show (NAIAS), now, according to Autoblog.com, reports suggest that Ferrari hasn't finalized the plans for a worldwide launch. So, Ferrari enthusiasts who have penned down the date on their calendar will sadly have to strike them off.

On the other hand, the Prancing Horse might consider a private launch, separate from all the big car shows, so that they can grab more attention and more people to drool over it. A likely reason for its change of plans is because of the unveiling of the sister brand's - Maserati - next generation Quattroporte->ke336. If debuted at the same show, the F70 would've drawn the entire Detroit population towards its stand leaving the Maserati stand deserted.

According to previous reports and a spy shot of the engine bay, the Ferrari F70 is expected to get a V12 engine with an F1-inspired KERS system that will pump out a combined output of 920 hp (686 kW). The supercar could have a curb weight of only 1134 kg (2500 lbs) thanks to a 20 percent lighter chassis made from carbon fibre. The carbon tub that underpins the F70 was shown off at the Paris Motor Show which was enough to increase the excitement and anticipation of its launch.
