Technically, the third-generation Coyote V8 in the refreshed, 2018 Ford Mustang GT is the first factory Coyote engine to actually displace 5.0 liters (slightly more than 5.0, actually). The engine’s new plasma transferred wire arc spray-in cylinder liners, borrowed from the cutting-edge 5.2-liter VooDoo V8 in the Shelby GT350, allow it to have thinner, lighter cylinder liners that increase the bore slightly, from 92.2 mm to 93 mm. The 92.7-mm stroke has been kept the same, resulting in 5.038 liters (307 cubic inches) of displacement instead of the old 4.951 liters (302 cubic inches).
That’s one of the many fascinating things we learned from Jason Fenske of Engineering Explained when he decided to provide an in-depth look at Ford’s new, third-generation Coyote V8. His latest video is to be the first in a series entitled “The Best Engines”, in which he takes a look at award-winning production engines currently available in the US market. The new Coyote won a “10 Best Engines” award from WardsAuto for 2018, thanks to its intoxicating potency and surprising efficiency.
Granted, an even bigger deal than its spray-in cylinder liners is the latest Coyote’s new dual-fuel-injection system, which couples direct- and port-injection to leverage the best qualities of each. This, Jason says, is “great from a carbon-buildup standpoint, but it also allows for better fuel control at high-load, high-rpm scenarios.” (Direct-injected engines are often faulted for their propensity for carbon-buildup on the intake valves, as unlike with port-injection, fuel is being sprayed directly into the combustion chamber rather than constantly “washing” the backs of the valves.)
Ford’s series of DOHC Coyote V8 engines represent an entirely different approach to making power than the pushrod V8s found in the Chevrolet Camaro and Dodge Challenger, and for 2018, Mustang buyers stand to gain even more from it. The power-dense aluminum engine pumps out up to 460 horsepower – 25 more than the second-generation Coyote in the 2017 Mustang GT – and revs to an impressive 7,500 rpm.
