2011 Ferrari 612 Scaglietti test mule exercising its vocal chords

Diehard supercar enthusiast Marchettino has caught the 2012 Ferrari 612 Scaglitetti test mule performing maneuvers at Ferrari's Fiorano test circuit in Maranello, Italy.  As seen before in previous spy photos, the prototype is still wearing the body of the current 612, but the car itself is not the main attraction of the video.  It's the sound!

Latest rumors place the media reveal in Geneva 2011 followed by a market launch in early 2012.

According to various reports, power will likely come from a V12 engine with at least 397 kW (533 hp / 540 PS) and 588 Nm (434 lb-ft) of torque. Backed up by a seven-speed dual-clutch transmission, the 612 should accelerate from 0-62 mph (0-100 km/h) in less than four seconds, before topping at 200+ mph (322+ km/h). Unlike today's model, the 612 replacement could offer an all-wheel drive system.

Also on deck, the new 612 will come with a hybrid powertrain. As previewed by the HY-KERS concept, which debuted at this year's Geneva Motor Show, the hybrid would probably feature a three-phase electric motor and a lithium-ion battery pack.

Since the car is expected to be launched in 2012, look for Ferrari to start testing full-body prototypes later this year.
