Ford's New V-8

The 6.2 is the engine the Raptor was always meant to have--the decision to launch with a tuned 5.4-liter Triton under the hood was made when the two development programs got slightly out of phase.

Built at Ford's Romeo engine plant, the new 6.2 is a conventional iron-block, aluminum-head V-8 with single overhead camshafts, variable camshaft timing, and two valves -- and two spark plugs -- per cylinder. The crank is secured by four bolt main bearing caps, cross-bolted for extra durability. Forged steel connecting rods are standard, as are lightweight magnesium cam covers and a composite intake manifold.

The base engine will debut in the 2011 Super Duty with 385 horsepower and 405 pound-feet of torque. A unique cam profile means the engine will pump out 411 horsepower at 5500 rpm and 434 pound-feet at 4500 rpm in Raptor trim.

The oversquare configuration (bore is 4.02 inchdes and stroke 3.74 inches) means the 6.2 revs harder than the long stroke Triton. Both power and torque peaks occur further up the rev band in the bigger engine. The 6.2 sounds different too -- leaner and meaner thanks, in part, to its different firing order.
