The 2010 model year Fusion (as well as the Milan) gains from a new engine lineup that includes Ford's brand-new Duratec 2.5-liter 4-cylinder unit that delivers an output of 175HP and 172 lb.-ft. of torque, 14HP more and 16 more lb.-ft. of torque than the preceding year's 2.3-liter unit. The 3.0-liter V6 engine has been reworked producing 19HP more and 23 more lb.-ft. of torque than before for a total of 240HP and 228 lb.-ft. of torque while for 2010, there's also a new 263HP 3.5-liter V6 engine.
What's even more important is that all three engine are paired with Ford's new six-speed automatic transmission. While Ford has yet to release any specific figures, the company supports that paired with the 6-speed auto, the 2.5-liter Fusion delivers a 10 percent improvement in fuel efficiency while the V6 configurations gain a 4- to 6-percent efficiency.
In 2009 Ford will also introduce the Fusion and Milan Hybrids equipped with a next-generation hybrid propulsion system. Te hybrid sedans can operate up to 47 mph in pure electric mode while Ford claims that the city driving range on a single city tank of gas is expected to be more than 700 miles. Furthermore, the company said that both the Milan and Fusion hyrbids are expected to achieve class-leading fuel economy, besting the Toyota Camry hybrid by at least 5 mpg.
