The Ford Mustang EcoBoost normally produces 310 horsepower and 320 lb. ft. of torque- not bad for a 2.3 liter in-line four cylinder engine. However, we’ve just learned that, in order to harness those numbers, it’s going to cost you more at the pump.
According to Ford training materials and Ford engineers, the 2015 Mustang EcoBoost is perfectly capable of running on 87 octane fuel and can run it “all day long” without any problems, but it will come at a cost- a cost of 35 horsepower and 20 lb. ft. of torque.
The total losses equate to an 11.3% loss in horsepower and a 6.3% loss in torque. While that’s’ not too obscene, it certainly is a significant margin, especially on the horsepower front. Consider this before taking your 2015 Mustang EcoBoost to the track.
