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.

“The Mustang engineering team aimed high and, through hard work, achieved fuel economy numbers that elevate Mustang into a class by itself,” said Derrick Kuzak, Ford group vice president, Global Product Development.

“At no other time in Mustang’s history – for that matter, in automotive history – have we been able to talk about 305 horsepower and 31 miles per gallon. The Mustang truly is a no-compromises sports car,” said Kuzak.

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.
