Which Ford Flex is twin turbo?
The twin-turbo Ford Flex is the EcoBoost-powered version—the 3.5-liter EcoBoost V6 engine—found on Flex models built from about 2013 through 2019. Non-turbo Flexes use the naturally aspirated 3.5L V6.
What makes a Flex twin-turbo
The term twin-turbo refers to Ford's EcoBoost technology: two small turbochargers that boost air intake for the V6, delivering more horsepower and torque without a large penalty in fuel economy. In the Flex, this means sharper acceleration, stronger towing capability for a family crossover, and higher output than the base V6.
Engine details
The 3.5-liter EcoBoost V6 in the Flex is typically paired with all-wheel drive and produces approximately 360 to 365 horsepower and around 350 pound-feet of torque, depending on model year and configuration. The engine uses direct injection, twin turbochargers, and an intercooler to maintain performance across a range of speeds. This powertrain replaced the earlier naturally aspirated 3.5-liter V6 in the lineup.
Model years and trims
Reviewing the Flex lineup reveals the EcoBoost option appeared on models spanning the mid-2010s. Use this guide to identify which model years commonly carried the twin-turbo EcoBoost V6 in the Flex lineup.
- 2013 model year — introduction of the EcoBoost V6 option on eligible trims
- 2014 model year — continued availability of EcoBoost V6
- 2015 model year — EcoBoost V6 carried on select trims
- 2016 model year — EcoBoost V6 offered in higher trims
- 2017 model year — EcoBoost V6 retained in SEL/Limited lines
- 2018 model year — continued EcoBoost availability
- 2019 model year — final year of EcoBoost availability before the model was discontinued
Models ranged in availability by trim and drivetrain; higher trims with features like AWD were more likely to include the EcoBoost engine, while base configurations often used the naturally aspirated V6. For certainty, consult the window sticker or a VIN-decoding tool for the exact build.
How to verify if a specific Flex has EcoBoost
If you are shopping for a used Ford Flex and want to confirm the twin-turbo EcoBoost configuration, use these verification steps. They help ensure you’re not confusing the naturally aspirated V6 with the EcoBoost version.
- Look for the EcoBoost badge on the exterior or engine cover, which signals the turbocharged engine
- Check the engine displacement and type on the engine bay label or under-hood stamping to confirm a 3.5L EcoBoost V6
- Review the window sticker and dealer documentation for “3.5L EcoBoost V6” or “EcoBoost” designation
- Ask the seller or dealer for the build sheet or VIN-based build confirmation, which will specify the EcoBoost option
- Take note of performance cues in test drives (torque-rich acceleration and turbo spooling sound) and ensure the vehicle is delivering power smoothly
These steps help confirm you are looking at the twin-turbo EcoBoost Flex rather than the naturally aspirated model.
Summary
The Ford Flex with twin-turbo capability is the EcoBoost-powered variant, specifically the 3.5-liter EcoBoost V6, offered from around 2013 through 2019. If you want the quick answer: look for EcoBoost badges, the 3.5L EcoBoost V6 engine, and documentation showing EcoBoost on the window sticker or build sheet. This engine delivered higher horsepower and torque for a more capable, albeit heavier, family SUV within Ford's Flex lineup.
