When it was first announced that the 5.0-liter engine was making a return to the 2011 Ford Mustang, none of us here at Autoblog were really that concerned with the fuel economy. We were all about the horsepower, and at 412 ponies underneath the hood, the 5.0 doesn't disappoint. Ford, however, was thinking about appearances and earth-hugging as well, and managed to make the 2011 Mustang even more efficient than the 2010 model despite all that extra extra power. According to the numbers released today, the new Mustang GT gets 17 miles-per-gallon city and 26 mpg highway with the six-speed manual and 18/25 mpg with the six-speed automatic.
These numbers are not only a huge improvement from the 2010 Mustang with the 4.6-liter V8 (15/23 mpg w/manual, 15/22 mpg w/automatic), but they also best the figures achieved by the Chevrolet Camaro SS - 16/24 mpg when equipped with a manual and 16/25 mpg with the automatic. As reported earlier, the 2011 Mustang V6 claims top honors against its Camaro counterpart as well with an impressive 19/31 mpg in six-speed automatic form.
So what accounts for the improved fuel economy despite the increase in displacement and horsepower? According to Ford, having an extra gear in the car's transmissions play a large role in addition to the Twin Independent Variable Camshaft Timing (Ti-VCT) that can quickly adjust the intake and exhaust valves.

2011 FORD MUSTANG GT LEADS CLASS WITH 26 MPG HIGHWAY, 412 HORSEPOWER
DEARBORN, Mich., March 16, 2010 – The 2011 Ford Mustang GT, powered by a new 412-hp 5.0-liter V-8 engine, adds yet another notch to its belt: an EPA rating of 26 mpg highway when equipped with the six-speed manual transmission, giving it the best fuel economy in its class.
"The 2011 Mustang continues to exceed expectations in every category, and these fuel economy numbers are another chapter in an incredible story," said Derrick Kuzak, Ford's group vice president, Global Product Development. "To offer this kind of horsepower and class-leading fuel economy in a comfortable, beautiful, tech-savvy and affordable package – it's really unprecedented."
With the six-speed manual transmission, Mustang GT coupe is rated at 17 mpg city and
26 highway, while models with the available six-speed automatic achieve 18 mpg city and
The GT's best in class fuel numbers come on the heels of the Mustang V-6, which just last week cracked the record books as not only the most fuel-efficient Mustang ever, but also the first production car in history to produce 305 horsepower and 31 mpg highway.
Mustang GT is powered by an all-new 5.0-liter double-overhead-camshaft (DOHC) V-8 with a host of advanced features to deliver the combination of power and class-leading fuel economy.
Twin Independent Variable Camshaft Timing (Ti-VCT) adjusts the valvetrain in microseconds depending on driver inputs. A carefully tuned intake and exhaust system ensures free breathing at all engine speeds. And all-aluminum construction results in a lightweight yet durable powerplant.
A pair of new transmissions, both with six forward ratios, also play a large part in making the 2011 Mustang a breakthrough car. Regardless of whether drivers want to shift for themselves or let the car shift for them, they're treated to carefully chosen gear ratios to maximize fuel economy while still delivering high-horsepower performance
"Mustang powertrain development has reached a point where customers don't have to choose between fuel efficiency and performance," says Barb Samardzich, Ford vice president of Global Powertrain Engineering. "Thanks to technologies like Ti-VCT and our six-speed gearboxes, a Mustang driver has the best of both worlds."
