A 2015 Ford Mustang GT with a factory-standard engine produces 300 horsepower. The car is also available with a turbocharged engine that produces 310 horsepower or an upgraded V8 engine capable of 425 horsepower.
The horsepower produced by the 2015 Mustang is down slightly from the 2014 model, which was capable of 305 horsepower. This is in the name of creating an engine that runs more efficiently and is more ecologically sound. The mid-range turbocharged EcoBoost engine is the first turbo Mustang produced by Ford since 1986. All engine options for the 2015 Mustang GT are available with a choice of automatic or manual transmission.
