2015 Mustang Engine Information – 302 cubic inch V-8 (5.0 L Coyote V8)
The 5L Coyote
The Coyote is a 5.0 liter, naturally aspirated V8 engine from Ford Motor used in the Ford Mustang and pickup trucks. Featuring a dual overhead cam (DOHC) design, in a V configuration, the Ford Coyote architecture has been part of the Ford Modular family since 2011.
With an increased push for engines that had more power and more economy, it was clear that that technology needed to improve dramatically, and that wasn’t going to be possible if Ford chose to stay with a traditional small-block engine. The modular engine had improved dramatically since the first iteration was used in a Lincoln Town Car back in 1990. Also, Ford had some exciting new technology that they couldn’t wait to add to the modular designs. 2010 was the first year that Ford added Twin Independent Variable Cam Timing to some of its engines.
The Coyote engine was designed to compete with the Charger Hemi and the Camaro’s LS3. Since 2011, a Coyote engine has been in all Mustang GTs and has been available as an option in upgraded F-150s.
Since 2011 this spectacular twin-cam 32-valve monster motor has been thrilling owners of Mustang GT’s with its colossal power and silky smooth operation and for 2015 Ford engineers made some revisions to make the 5.0-litre even better. There is a rebalanced forged steel crankshaft and sinter forged connecting rods that are lighter and more durable to support higher-rpm operation with less vibration. This revised crankshaft is need in order to withstand the riggers of the 7,000 rpm redline that is possible thanks to new cylinder heads, valvetrain and intake manifold that allows this stunning V-8 to breath more freely from idle all he way up t redline.
Straighter intake ports in the cylinder head improve air flow while larger intake and exhaust valves allow more air into and out of the cylinders for more power. To take advantage of the larger valves both the intake and exhaust camshafts were revised and stiffer valve springs added to ensure that the valves close completely at high rpm. The combustion chamber was also modified along with redesigned piston tops with deeper cutouts to accommodate the larger valves were also thrown in. Engineers also played with the variable camshaft timing on the intake side allowing a greater range of adjustment. This change optimizes valve timing over a greater range of rpm and primarily improves both emissions and fuel economy making the big bad V-8 a little more environmentally friendly; that is until of light up the tires for a smokey burnout.
The new intake manifold features charge motion control valve plates that partially close off port flow at lower engine speeds. When the ports are partially closed this causes the air charge to tumble and swirl allowing the fuel and air to better mix. This improved mixture burns more efficiently in the combustion chamber resulting in better idle stability, fuel economy and lower emissions; all good things.
All the modifications have conspired to boost power of the 5.0-litre up to 435-horsepower and 400 pound-feet of torque, just shy of the 444-horsepower produced by the epic 2012-2013 Boss 302!
