Finally, under the hood, Ford will offer five all-new powertrains; two of which are quite exotic. On the bottom, the new Fusion will sport an all new 2.5 liter four-cylinder that will improve power and mileage over the current four-cylinder engine. The second engine will be the much coveted and much-clamored-for 3.5l V6 used in the Taurus and Edge – this engine is both more powerful and more economical than the current V6 offered in the Fusion. The third system offered will be a standard parallel full hybrid with a continuously variable transmission. This will be a brand new system dubbed “Gen II” – which is modeled after the Escape hybrid, but offers more US-sourced technology, better packaging flexibility, and better fuel efficiency. This system will debut with the Fusion and then spread across Ford’s lineup in the US and abroad.

The final two engines are the reason for excitement, however. Ford will offer two Twin Force engines, positioned as alternatives to both the four and the six cylinder engines while delivering excellent mileage. The smaller of the duo will deliver between 170-200 horsepower, and in preliminary testing, is approaching a fuel efficiency rating of 30 miles-per-gallon in the city and 40 miles-per-gallon on the highway. And while the final rating will likely be a bit shy of the nice numbers above, the Fusion with this engine will still deliver mileage in the compact-car territory. The displacement of this smaller Twin Force engine has not been revealed yet, but most likely will be a 1.6 or 1.8 liter. The larger of the Twin Force duo will be a version of the 2.5l four cylinder delivering over 260hp, and over 30 miles per gallon highway.
