It’s Official: Ford Releases 2015 Mustang Horsepower Ratings

2015 Mustang BurnoutThe GT gets a boost in horsepower and torque, EcoBoost comes in north of 300HP and like we reported previously and the V6 makes less power than it did in 2014.

2015 Mustang Horsepower and Torque Ratings

GT: The wait is finally over. The 2015 Mustang GT will come from the factory with 435 horsepower and 400 torque at the crank–a slight increase of 15HP/10TQ over the 2014 Mustang GT. Compression ratio comes in at 11:1.

According to multiple sources at Ford and elsewhere, that’s good enough to beat the 2012-2013 Boss 302 Laguna Seca.

EcoBoost: The 2015 Mustang’s 2.3L EcoBoost (EB) motor draws in at 310 horsepower and 320 foot-lbs of torque. For comparisons sake, that’s 110 horsepower and 80 foot-lbs of torque more than the 1986 SVO. It’s also worth noting the new turbo 4 cylinder is tuned for 93 octane fuel with a compression ratio of 10.5:1 and is the first in Ford’s lineup with a twin-scroll turbocharger.

That’s good for about 135 horsepower per liter and 139 lb.-ft. of torque per liter, “the best-ever power density from a production Mustang engine” according to Ford.

V6: Here’s where things get dicey–it appears Ford, likely in an effort to better establish the EcoBoost as a premium upgrade over the V6, actually dialed back the base model car’s previous 305 horsepower rating to an even 300 horsepower. Torque remains at the previous 280 ft-lb mark and the car retains its 10.5:1 compression ratio.

The drop in horsepower for the V6 is probably not what some Mustang enthusiasts would want to hear. However, if the previous generation V6 Mustang wasn’t throaty or aggressive enough, Ford has said that the “3.7-liter V6 engine now has a more refined growl that communicates the performance a driver can expect from 300 horsepower underhood.”

2015 Mustang Burnout - 435 HorsepowerWhile we’ve been busy mulling over horsepower number for the GT, EB and V6, Ford has been busy as well. Just yesterday we received track footage of the new GT350 Mustang that, by all indications, is set to come with a naturally aspirated flat plane crank V8–a spin-off from the current Coyote engine. Power figures for SVT’s newest project are likely still a ways off, but you can bet on the GT350 being a solid competitor of Chevy’s new Z/28 Camaro.


    1. I’m sorry but when I hear a mustang there is no sound like a v8 and there is no point to any other engine in a car that is suposed to be a muscle car


    1. Actually, it was both a slight increase in power and weight. I’m guessing the power increase is more marketing and less improvements.
