A chart tracking the output of the Ford pony car for the past 50 years shows that from 2009 to 2014, the Mustang has been gaining power. Aside from a slight dip from 2013 to 2014, the power numbers hover well beyond the 400-horsepower mark, as highlighted in a Mustang News report . The Ford Mustang comes standard with a 2.3-liter EcoBoost turbocharged four-cylinder engine that produces 310 horsepower and 350 pound-feet of torque. An optional performance package raises horsepower output to 330. The Mustang GT has a 5.0-liter V8 engine that puts out 460 horsepower and 420 pound-feet of torque. The Fox-body Mustang, in many ways, is the perfect entry point to classic muscle ownership without having to pay the Boomer tax that's afflicted 1960s and '70s offerings. A driver-quality, final-year GT can be had for less than $7500, and you'll be looking at around $20,000 for the best concours-quality Fox-body you can find. .
