With the release of the seventh-generation S650 Ford Mustang, it was natural that the Mustang would get a revised, all-new version of the Coyote powertrain. This will mark the release of the 4th generation of the Coyote V8 engines with improved horsepower and durability over the 3rd generation of the Coyote. The highly sought-after Dark Horse also has the Coyote V8, but it features a slightly more powerful version due to its unique dual-throttle body intake design. In comparison, the 2.3L Ecoboost four-cylinder engines remain relatively unchanged from previous generations.
The 2.3-liter Ecoboost turbocharged four-cylinder engines have received a small bump in power. The I4 2.3L is now rated at 315 rear-wheel horsepower from the previous figure of 310. The 2.3L also makes a whopping 350 ft/lb torque figure. These power gains are primarily from redesigned tuning through the PCM. It also uses a new Bore to Stroke ratio, Port Fuel injection coupled with direct injection, variable cam timing, integrated Exhaust Gas Recirculation, and Twin Scroll turbocharging technologies to deliver added performance.
The standard 5.0-liter Coyote V8 in the Ford Mustang GT has jumped to 486 horsepower over 460 for the Gen 3. A revised four-into-one exhaust manifold helps promote improved airflow exiting the engine. Additional cooling modifications across the V8 are another area in which these engines have shown advancements. A steel oil pan is also an upgrade over the previously used composite design for added strength and rigidity.
The Dark Horse received a uniquely balanced crankshaft and forged-steel I-beam connecting rods from its older big brother 5.2L Predator Engine found in the 2020-2022 Mustang Shelby GT500s. This, paired with the upgrades found on the standard Coyote, makes it a potent force to be reckoned with.
