All-New Ford Fusion Hybrid America's Most Fuel-Efficient Mid-Size Car

The all-new Ford Fusion Hybrid is now officially America's most fuel efficient mid-size car with a certified 41 mpg rating in the city and 36 mpg on the highway, topping the Toyota Camry hybrid by 8 mpg in the city and 2 mpg on the highway.
"The new Ford Fusion Hybrid not only significantly exceeds the competition but also embodies Ford's 100 percent commitment to fuel efficiency leadership, quality, innovation and advanced technology," said Derrick Kuzak, group vice president, Global Product Development. "The Ford team set the bar high -- to develop America's most fuel efficient mid-size sedan -- and that's what they delivered."

The 2010 Ford Fusion's final fuel economy certification was completed this week at Ford's testing laboratories in Allen Park, Mich., and the vehicle will carry an EPA label of 41 mpg for city driving and 36 mpg on the highway when it goes on sale this spring. The Fusion Hybrid, which beats even the much smaller Honda Civic hybrid by 1 mpg in city driving, can travel more than 700 miles on a single tank of gas.

To deliver the class leading fuel economy performance, Ford's engineers spent the past three years developing in-house the vehicle's next-generation hybrid propulsion system. It allows the Fusion and Mercury Milan hybrid to travel up to 47 miles per hour in pure electric mode, faster than the Toyota Camry and all other hybrids currently on the road. In addition, the system's Advanced Intake Variable Cam Timing allows the Fusion and Milan hybrids to more seamlessly transition from gas to electric mode and vice-versa.

"The Fusion Hybrid's ability to run at a much higher speed in electric mode allows drivers to maximize fuel efficiently in many driving situations," said Praveen Cherian, Fusion Hybrid program leader. "For example, this would allow drivers to travel around their subdivision and parking areas in all-electric mode."

Fusion's advanced hybrid system features:

-- Smaller, lighter nickel-metal hydride battery, which produces 20 percent more power than Ford's previous hybrid system. The battery's improved chemistry allows it to be run at a higher temperature and cooled using cabin air.

-- New 2.5-liter 4-cylinder engine (155 horsepower / 136 lb.-ft. of torque), which is mated to an electronically controlled continuously variable transmission.

-- Enhanced electronic throttle control, which reduces airflow on shutdowns, reducing fueling needs on restarts.

-- Smart climate control system, which monitors cabin temperature and only runs the gas engine as needed to heat the cabin. It also includes an electric air conditioning compressor to further minimize engine use.

-- Regenerative brake system, which captures the energy normally lost through friction in braking and stores it. Nearly 94 percent energy recovery is achieved by delivering full regenerative braking, which means only 6 percent of braking is through traditional friction brakes
