With the 2010 model year, Ford is marking the start of its EcoBoost initiative, a plan that will dramatically effect the company's entire lineup in the coming years. By using turbocharging and direct injection with smaller-displacement engines, Ford says it can offer better performance and fuel economy. The company expects it will put 1.3 million EcoBoost engines on the road by 2013 and offer the technology in 90 percent of its models.
The Flex crossover is one of the first Fords to get EcoBoost. Using a 3.5-liter V-6, the Flex achieves V-8 performance with V-6 fuel economy. The Flex EcoBoost (which is only available with all-wheel drive) achieves the same fuel economy as the base all-wheel-drive Flex, which is rated at 16/22 mpg.

The technology in Ford's EcoBoost engines isn't revolutionary, but the company's plan for such widespread adoption is unique. In the 3.5-liter V-6, two turbochargers spin as fast as 170,000 rpm to force more air into the engine while fuel injectors spray gasoline into the cylinders at 2175 psi. Adding more air and fuel allows extra power to be squeezed out of each combustion event.
There are plenty of automakers that might detune a performance engine by 10 to 20 hp in the family crossover, but the Flex receives the same 355 hp that will move the Ford Taurus SHO, the Lincoln MKS, and the Lincoln MKT.... Read full article
