Ford’s been quiet about the 2015 Ford Mustang’s official power ratings since launching the car at the Detroit auto show, but the company has now finally revealed power and torque numbers for all three of the new Mustang’s powertrains, including the 5.0-liter V-8, the 2.3-liter EcoBoost turbo four-cylinder, and the base 3.7-liter V-6.
Based on Ford’s initial ballpark figures of more than 305 hp for the EcoBoost and more than 420 hp for the V-8, the actual numbers aren’t too far off. The Mustang GT’s V-8 pumps out 435 hp and 400 lb-ft of torque, the EcoBoost four-cylinder makes 310 hp and 320 lb-ft of torque, and the V-6 makes 300 hp and 280 lb-ft of torque.
Compared with last year, the 2015 Ford Mustang's base V-6 has actually lost 5 hp, presumably in order to make more of a gap between the V-6 and the new EcoBoost four, which costs $1570 more than the V-6 coupe. The V-8’s power compares favorably to last year’s model, though, as hp is up by 15 and torque is up 10 lb-ft compared to the 2014 car thanks to larger intake and exhaust valves and an improved cylinder head.
There’s also been a lot of speculation about how much the new 2015 Ford Mustang weighs, and we now know that it won’t gain many pounds compared with the current car. The base 2015 Mustang V-6 coupe with the manual transmission weighs 3526 lbs, a 30 lb increase over last year; the EcoBoost manual coupe weighs 3532 lbs, just 6 lbs more than the V-6; and the V-8 manual coupe weighs 3705 lbs, an 87 lb increase over the 2014 Mustang GT.
All three engine choices pair with either a standard six-speed manual or an optional six-speed automatic, and neither transmission choice has any effect on the engines’ respective power outputs. Pricing for the 2015 Ford Mustang, which goes on sale later this fall, starts at $24,425 for the V-6 coupe, $25,995 for the EcoBoost coupe, and $32,925 for the V-8 Mustang GT coupe. The convertible model starts at $29,925 with the V-6, $35,495 for the EcoBoost Premium, and $42,425 for the GT Premium.
