Americans would feel proud that they developed the most fuel efficient midsize sedan by their own. Since the 2010 Fusion Hybrid has already passed the fuel efficiency testing by the EPA, it win the Toyota Camry Hybrid on distance covering per gallon, by 2 mpg in the city and 8 miles to the gallon in the city.

The EPA is rated 41 mpg in the city, while Ford’s supposed to be 39 mpg. However, its highway rating of 36 mpg is worse than expected. The figure can be expected to be the same for the mercury Milan Hybrid. If true, the referred two cars could cover a remarkable distance of 700 miles on a single tank of gas.

Derrick Kuzak, team vice president, Global Product Development of Ford revealed, “The Ford team set the bar high - to develop America's most fuel efficient mid-size sedan - and that's what they delivered”.

As Ford told the public, the Fusion Hybrids and Milan can travel at a speed up to 48 mph in pure electric mode and that is a faster speed than that of all other hybrids available on the road. Ford represents that some auto journalists could exceed 50 mpg on an urban drive loop, due to the Hybrid's SmartGauge with EcoGuide.

The fuel economy midsize cars will be on sale in America before this summer arrives, costing $25,000 or so.
