The one-off Ferrari F12 TRS has been photographed once again, this time by WCF collaborator and friend Marchettino.

You are looking at what could be the most expensive Ferrari in the company's history as the F12 TRS is believed to have a staggering price tag of 4.2M USD, making it a lot pricier than the rumored 2.8M USD LaFerrari Spider. It's essentially a targa conversion of the F12 Berlinetta but it wears a considerably different body that provides a more aggressive appearance.

Aside from the obvious styling changes, the F12 TRS is rumored to pack a KERS system which means the V12 6.2-liter naturally-aspirated engine works with an electric motor to provide an output beyond the 740 PS (544 kW) and 690 Nm (509 lb-ft) available in the standard F12. Chances are the KERS system is derived from the LaFerrari where it develops 163 PS (120 kW) and 270 Nm (199 lb-ft).

Additional details and images will be available this weekend as the F12 TRS will be seen in action at Ferrari Cavalcade in Sicily.
