Ferrari 612 Scaglietti Engine

The 612 Scaglietti's front-mounted engine is a special development of the 575M Maranello's twelve cylinder motor. The 5,748 cc 65° V12 dual overhead cam per cylinder bank, four valves per cylinder powerplant of the four seat coupe is the pinnacle of Ferrari technology. Like the cars' structure, the engine block, cylinder heads and sump are all made from aluminum alloy. The dry sump lubrication system features an oil and water pump in one unit, with two scavenge and one delivery pump, two oil filters and a dedicated oil radiator.

Other features include steel cylinder liners, hydraulic tappets, and variable intake manifolds with an extra central plenum that improves fuel-air swirl. A massive 540bhp (DIN) at 7,250rpm and 434ft-lb at 5,250rpm belie the broad power and torque curves that allow the car to perform exceptionally well at low and medium engine speeds in every gear. The big V12 benefits from modifications that have optimized its performance and fluid dynamics.

The most important are intake tracts with separate ducts per cylinder bank from the radiator grille opening on the front bumper, and exhaust porting and system geometries and volumes that reduce back pressure. Electronic engine control is by a single Bosch Motronic ME7 CPU per cylinder bank which jointly control the PFI multiplex injection and drive-by-wire system. Four knock sensors are positioned in the engine block.
