Here are some key facts about Ford Flex and EcoBoost

  • The 3.5-liter EcoBoost engine delivers an impressive 355 horsepower and a responsive 350 lb.-ft. of torque across a broad rpm range, simultaneously giving Ford Flex the power of a normally aspirated 4.6-liter V-8 while enjoying V-6 fuel efficiency.
  • The twin-turbocharged 3.5-liter EcoBoost V-6 engine requires all-wheel drive and will be available on well-equipped SEL and Limited models of the 2010 Flex, packaged with several high-demand customer features.
  • The 3.5-liter EcoBoost V-6 is the first in a wave of EcoBoost engines coming from Ford as part of a strategy to bring major fuel-efficiency improvements to millions.
  • The key to the EcoBoost system is the harmony between the twin turbochargers and the direct injection fuel system. The turbochargers recover energy from the exhaust that otherwise would’ve been wasted and put it back in the engine to gain efficiency.
  • By 2013, more than 90 percent of Ford’s North American lineup will be available with EcoBoost.

Quotes

“We are committed to delivering fuel economy leadership in every new vehicle. We do this with affordable technology that can be applied to the widest number of vehicles. EcoBoost is an important component of that goal. The beauty of EcoBoost is that it enables us to downsize for fuel efficiency, yet boost for power. We’re able to decrease the size of the available engine – such as installing a V-6 versus a V-8 – yet boost the power using turbocharging to deliver similar power and torque of that larger engine.”
- Derrick Kuzak, Ford’s Group President of Global Product Development

“We know that there are customers who are looking for the power and performance of a traditional V-8 but are not willing to sacrifice this for fuel economy.
