The Ford Coyote 5-liter engine is a V8 dual-overhead cam engine that produces 435 horsepower and 400 foot-pounds of peak torque in its 2015 Mustang GT version. A torque-biased version is used in Ford's 2015 F150 pickup that produces 385 horsepower and 387 foot-pounds of torque.
The 2015 version of the Coyote engine is an evolution of Ford's Modular V8 design. Despite popular misconceptions about the name, the Modular engine series is not specially designed to be swappable into multiple car models. The engines are actually named after the modular manufacturing process used to quickly retool the production factory to produce new variants of the engine.
The Coyote was designed primarily to serve as the engine for the 2011 Ford Mustang GT. It was necessary to keep the size of the engine similar to the 4.6-liter V8 that powered the Mustang GT in previous model years, so the Coyote shares the same 100-millimeter bore spacing and 150.7-millimeter connecting rod. The engine's increased displacement comes from larger 92.1-millimeter cylinder bores and a longer 92.7 millimeter stroke length. The Coyote also features a new four valve per-cylinder design to increase airflow to the engine. To accommodate the space restrictions in the Mustang GT engine bay, Ford engineers moved the alternator from its traditional position to the side of the engine block.
