Does the Ford Flex have an EcoBoost engine?

Yes, the Ford Flex does offer an available EcoBoost engine option. The EcoBoost engine is a turbocharged and direct-injected engine that provides increased power and efficiency compared to a traditional naturally-aspirated engine.


Detailed Overview of the Ford Flex EcoBoost Engine


The Ford Flex is a full-size crossover SUV that has been in production since 2008. While the base model Flex comes equipped with a naturally-aspirated 3.5-liter V6 engine, Ford also offers an optional EcoBoost engine for the Flex.


The EcoBoost engine in the Ford Flex is a 3.5-liter twin-turbocharged V6 that produces 365 horsepower and 350 lb-ft of torque. This represents a significant increase in power compared to the standard 3.5-liter V6, which generates 287 horsepower and 254 lb-ft of torque.


In addition to the power boost, the EcoBoost engine also provides improved fuel efficiency. The EcoBoost-equipped Flex is rated at 16 mpg city and 22 mpg highway, compared to 17 mpg city and 24 mpg highway for the standard V6 model.


Advantages of the EcoBoost Engine



  • Increased Power: The twin-turbocharged EcoBoost V6 engine delivers significantly more horsepower and torque than the base V6, providing a more responsive and powerful driving experience.

  • Improved Fuel Efficiency: Despite the power increase, the EcoBoost engine maintains relatively good fuel economy, with ratings only slightly lower than the standard V6.

  • Towing Capacity: The additional torque from the EcoBoost engine allows the Ford Flex to tow up to 5,000 pounds, compared to 4,500 pounds for the standard V6 model.


Overall, the available EcoBoost engine is a compelling option for Ford Flex buyers who want a more powerful and efficient driving experience from their full-size crossover SUV.
