Find out more about the 2010 Ford Fusion and Fusion Hybrid in the 2008 Los Angeles Auto

The 2010 Ford Fusion brings big changes in the powertrain department, with more to come once Ford's much anticipated EcoBoost engines finally happen. A majority of Fusions will be equipped with an all-new 2.5L Duratec inline-four, cranking out 175 hp and 172 lb-ft of torque and allowing a 9.5-sec sprint from 0 to 60 mph.

Transmission options will include a six-speed manual or six-speed automatic. Next up the food chain is the midlevel Fusion with a 3.0L V-6 good for 240 hp (250 hp in E85 spec) and 228 lb-ft of torque that knocks 2.5 sec off the 0-to-60-mph run, dropping it to 7.0 sec flat. We don't have fuel-economy figures yet, but Ford is integrating an "aggressive" fuel shutoff program on deceleration as well as electric power steering, conserving engine power. The top-level 2010 Fusion Sport will feature a 3.5L V-6 (the same unit used in the Flex) that will offer 263 hp and 249 lb-ft of torque. Ford says all-wheel drive will be available with the 3.0L and 3.5L six-cylinder engine options. Ford will also be releasing a hybrid version of its 2010 Fusion that the automaker claims can operate in all-electric mode at a cruising speed of up to 47 mph. Ford also claims the Fusion Hybrid will be capable of an average fuel economy rating 5 mpg better than that of the Toyota Camry Hybrid, putting mileage at nearly 40 mpg. The Hybrid will be powered by a 2.5L Atkinson cycle four-cylinder engine paired to an electric motor of unspecified output. Ford did mention it has reduced battery size and weight, and has incorporated a simplified cooling system that does not require an extra air-conditioning system as in previous models.
