Ford's Flex has a new heart this year, new motivation for both the vehicle and perhaps for those interested in buying it. It's Ford's Ecoboost technology, which includes the company's new twin turbo 3.5 liter V6 that Ford says delivers V8 power with V6 fuel economy. It's a peach of a system and it produces 355 horsepower, which Ford says is 35 percent more than that of the base Flex's V6, and 350 ft.-lb. of torque, up 41 percent.
