The 2015 Ford Coyote motor is a 5-liter V8 engine that produces 435 peak horsepower and 400 foot-pounds of torque in the 2015 Ford Mustang GT. The version of this engine used in the Ford F-150 produces 385 horsepower and 387 foot-pounds of torque.
The Ford Coyote V8 is an evolution of Ford's Modular engine line, based heavily on the 4.6-liter V8 used in the Mustang GT before 2011. It is a 32-valve dual-overhead cam design that shares the earlier 4.6-liter engine's 100-millimeter bore spacing and 105.7-millimeter connecting rods, but has an increased 92.3-millimeter bore diameter and 97.2-mm stroke length as compared to the older engine. The Coyote uses an indirect fuel injection system and has a compression ratio of 11:1. One of the unique features of the Coyote engine is its independent variable cam timing system, Ford's first version of such a system at the time of the engine's development.
The primary use for the Coyote is as the engine for the Mustang GT and as an engine option on Ford F-150 trucks, where the engine is tuned for low-end torque. While the maximum output of the engine is lower in the F-150, peak torque occurs at 3850 rpm rather than at 4250 rpm as in the Mustang. The Coyote is also the basis of the Voodoo engine, a 5.2-liter derivative used in the 2015 Ford GT350.
