More MPG Per HP – 2011 Ford Mustang

By Kevin Gordon

Once, a soon-to-be-dead older man told Tobey Maguire “with great power comes great responsibility.” It appears as if the engineers at Ford took this statement to heart. The American muscle car wars have always been about numbers. Most of the time the numbers were focused on how fast to 60, or horsepower and torque. Now, Ford gear heads can stand around their local car show and brag about their miles per gallon.

I remember hearing on launch of the new Corvette ZR1 that it was the most fuel efficient 600 HP car ever built (it gets 20 MPG highway) and I thought to myself, what a useless statistic. Well, I guess that muscle car MPG deserves more respect than I had given it. Ford’s recently announced EPA mileage numbers for the 2011 Mustang V6 and V8 have captured the media’s attention.

The new 3.7 liter V6 that replaces the box-of-rocks 4.0 manages 305 horsepower while attaining 19 MPG city, and a very impressive, 31 MPG on the highway. That rating is when you order your Mustang with the new six-speed slushbox, if you opt for the manual you lose a single MPG to still impressive 30 MPG. This outpaces the new Camaro by 2 MPG and makes the 2011 Mustang V6 the first 300 HP car to make 30 MPG. Think to yourself; if someone had asked you if there was a 300 HP 30 MPG car, would you have answered no? Now, imagine what Ford will be able to do with this motor in a car that doesn’t have the coefficient of drag of a lunchbox. Zinger! And I kid, because despite a first look, Ford did do extensive work on the aero package for this car.

The new 5.0 liter V8, despite having ~100 more HP than the outgoing 4.6 liter V8 manages 17 MPG city and 26 MPG on the highway. In contrast to the V6 you get your best MPG on the highway with the manual. When equipped with the automatic you gain one MPG to 18 in the city and lose one to 25 on the highway. Again, these numbers beat the new Camaro. (Notice the intentional lack of mention about anything from Dodge?)

So it does appear that Ford is being more responsible with its power and ultimately that is great news for the auto enthusiast. Press releases follow.

Release for the V6:

  • New 2011 Ford Mustang V-6 final fuel economy certified by EPA this week at 31 mpg on the highway and 19 mpg in the city
  • On sale this spring, Mustang with new 3.7-liter V-6 achieves 305 hp with available six-speed automatic transmission; first car ever to achieve 300-plus horsepower and 30-plus mpg
  • New Mustang already has more than 11,000 orders, half for the new V-6

DEARBORN, Mich., March 4, 2010 – The 2011 Ford Mustang today breaks new ground, cracking the record books as not only the most fuel-efficient Mustang ever, but also the first production car in history to produce more than 300 horsepower and more than 30 mpg highway.The Mustang’s official EPA ratings – completed this week – certify that models equipped with the 305-hp 3.7-liter V-6 and available six-speed automatic transmission achieve 31 mpg on the highway and 19 mpg in the city. The standard six-speed manual transmission is rated at 30 mpg on the highway and 19 mpg in the city.

Mustang is powered by a lightweight, all-aluminum 3.7-liter dual-overhead-cam (DOHC) V-6 engine that uses advanced engineering to deliver its combination of power and economy. Twin Independent Variable Camshaft Timing (Ti-VCT) adjusts the valvetrain in microseconds depending on driver inputs, further contributing to the engine’s overall efficiency.

The fact that Mustang achieves its top fuel economy rating with the convenience of an automatic transmission also marks a shift in conventional wisdom. Ford engineered a modern six-speed automatic transmission with carefully calibrated gear ratios and shift programs to maximize economy, while still delivering high-horsepower driving fun.

“Advanced powertrains like our Ti-VCT V-6 and six-speed automatic really speak to the future of Mustang,” says Barb Samardzich, Ford vice president of Global Powertrain Engineering. “We’ve proven that, using technology, Ford can deliver both power and fuel economy.”

In addition to engine improvements, upgrades to Mustang’s body, powertrain and chassis design contribute to the higher fuel economy numbers for 2011. Examples include:

  • New Electric Power Assist Steering (EPAS) system eliminates the drag of an engine-operated hydraulic power steering pump
  • Six-speed manual and automatic transmissions allow lower cruising revs without sacrificing off-the-line performance
  • Aerodynamic changes include improvements like a new front fascia, tire spats on the rear wheels, modified underbody shields, a taller air dam and an added rear decklid seal

The new 2011 Mustang already has more than 11,000 orders. Half of all the nationwide orders are for the car’s fuel-efficient 3.7-liter V-6 engine. The 2011 Mustangs are also being equipped with record levels of technology, giving customers the option of choosing navigation, high-intensity discharge (HID) headlamps and rearview cameras.The new 2011 Mustang goes on sale this spring and will be built at the AutoAlliance International Plant in Flat Rock, Mich.

Release for the V8:


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 25 highway.

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.”
