Ford Releases Horsepower Ratings for 2015 Mustang
After first revealing the 2015 Mustang late last year, Ford has put out final horsepower ratings on the new model. The standard 3.7-liter V-6 actually loses 5 horsepower, coming in at a total of 300 horses and around 280 lb-ft of torque. An all-new 2.3-liter EcoBoost four-cylinder engine pumps out 310 horsepower and 320 lb-ft of torque while achieving top fuel economy. Meanwhile, the top 5.0-liter V-8 engine gains 15 horsepower and 10 lb-ft of torque, coming in at 435 horses and 400 lb-ft of torque for the new model year. Expanding the Mustang's reach, the new EcoBoost engine is Ford's first vehicle to use a low-inertia twin-scroll turbocharger for quicker response time and increased efficiency. The new EcoBoost also includes direct-injection, twin independent variable camshaft timing, and separated exhaust ports that reduces pumping loss. Ford's classic 5.0-liter V-8 model also receives a number of upgrades to warrant the increased horsepower ratings. Larger intake and exhaust valves, revised camshafts, and new cylinder head casting were a large part of the equation. Overall, the changes were inspired by the 2012 Boss 302. Along with revised engines, Ford has also made tweaks to its transmissions. The manual promises easier engagement and a more precise drive thanks to a new shift linkage design. The automatic gets a redesigned case with cast-in ribs, reducing weight. The clutches have also been designed to reduce friction. And thanks to a new ball bearing that supports the output shaft, the top Mustang GT can now reach a top speed of 155 mph. Source: Ford
