Yes. The Ford Flex could be equipped with Ford's twin-turbo EcoBoost V6 in certain years and trims, but many early models used a naturally aspirated V6.
Overview of the engine lineup
Understanding which engines powered the Flex helps explain when a twin-turbo setup was available and why some buyers remember the EcoBoost option more than others.
- 3.5L Ti-VCT V6 (non-turbo): The original engine for early Flex models, delivering solid daily performance without turbocharging.
- 3.5L EcoBoost V6 (twin-turbo): An optional upgrade on later model years and higher trims, offering significantly more power and torque. Output is commonly cited around the mid-300s horsepower with ample torque, and all-wheel drive availability depended on the drivetrain package.
The EcoBoost option represents a meaningful performance boost compared with the naturally aspirated V6, but availability depended on year, trim, and market.
Availability by year and trim
Which Flex you could order with EcoBoost varied over the model run. The twin-turbo option appeared primarily in mid-to-late production years and on higher-end trims.
- 2013–2014: EcoBoost V6 was offered on select trims (typically SEL and Limited) with possible all-wheel drive combinations.
- 2015–2019: EcoBoost remained available on higher trims and as part of optional packages; drivetrain choices often included AWD.
When shopping used, verify the exact engine with the window sticker or VIN, since configurations changed by year and market.
Performance vs. fuel economy considerations
Choosing the EcoBoost twin-turbo engine affects acceleration, towing capability, and fuel economy. The turbocharged setup delivers stronger off-the-line power and highway passing capability, but it can come with reduced real-world fuel efficiency compared with the non-turbo V6, especially in city driving. Maintenance considerations for turbocharged engines are also worth noting.
- Pros: Improved acceleration and highway capability; potential for better towing support in a larger crossover.
- Cons: Slightly lower fuel economy in typical driving, higher complexity and potential maintenance costs compared with the non-turbo V6.
As with any used vehicle, condition and maintenance history heavily influence real-world performance and reliability.
Bottom line
The Ford Flex did offer a twin-turbo EcoBoost V6 option in several model years, but it was not universal across all trims or years. If you’re considering a Flex, check the engine type on the window sticker or via the VIN to confirm whether the EcoBoost twin-turbo engine is installed.
Summary
In short: Yes, the Ford Flex could be equipped with a twin-turbo EcoBoost V6 in certain years and trims, providing a notable power boost over the base engine. However, not every Flex had this option, and production ceased in 2019. Always verify the exact engine configuration before purchasing.
