How much horsepower does a 3.5 Ford Flex have?
The Ford Flex's 3.5-liter engine lineup comprises two power levels: 287 hp for the base 3.5L Ti-VCT V6 and 365 hp for the 3.5L EcoBoost turbo variant.
In this article, we explain how horsepower varies by engine and model year, and how to identify which engine your Flex has. The model range from 2009 to 2019 saw several updates, with the EcoBoost option appearing in later years.
Engine options and horsepower
The following summarizes the two 3.5-liter engine options you could find in the Ford Flex, along with their horsepower ratings.
- 3.5L Ti-VCT V6 (naturally aspirated) — 287 horsepower
- 3.5L EcoBoost V6 (turbocharged) — 365 horsepower
These numbers reflect typical ratings for the respective engines; exact horsepower can vary with trim, drivetrain (FWD vs AWD), emission equipment, and testing standards used for different model years.
In short, your Flex's horsepower depends on which 3.5-liter engine it uses: 287 hp for the standard V6, or 365 hp with EcoBoost.
Year-by-year availability and notes
Overview of when each engine was offered and what to expect in terms of performance across model years.
Non-turbo 3.5L V6 Ti-VCT
This engine powered early Ford Flex models (roughly 2009–2012/2013). It delivers about 287 hp and 254 lb-ft of torque and is typically paired with a conventional automatic transmission, without turbocharging.
EcoBoost 3.5L V6 turbo
Introduced in later model years, the EcoBoost option provides a substantial horsepower boost to around 365 hp and about 350 lb-ft of torque. It was available on higher trims and some all-wheel-drive configurations, with variations depending on year and equipment.
What you should verify when shopping
To ensure the horsepower figure matches the exact vehicle, check the window sticker (Monroney label), the VIN-based build sheet, or Ford’s official documentation for that model year. Options and calibrations can yield slight differences in output.
Summary: The Ford Flex offered two 3.5-liter engine options — a standard Ti-VCT V6 at 287 horsepower and an EcoBoost turbo version at 365 horsepower. The precise figure depends on the model year, trim level, and drivetrain; verify the specific vehicle’s specifications for an exact number.
Is the Ford 3.5 L V6 a good engine?
Yes, the Ford 3.5L V6 is generally considered a good engine, known for its strong performance, high torque, and efficiency, especially the EcoBoost twin-turbocharged versions. However, older models (1st generation) had some common issues like carbon buildup and cam phaser problems, which were significantly improved in later generations. Proper maintenance is key to ensuring its longevity, especially regarding regular oil changes and coolant flushes.
Pros
- Powerful and efficient: The EcoBoost versions offer high horsepower and torque, with much of the peak torque available at low RPMs. This makes them great for towing and performance.
- Broad torque band: The engine has a wide and flat torque band, meaning there's power available across a wide range of engine speeds.
- Smooth performance: It provides a smooth driving experience, with the 10-speed transmission working well to keep the engine in its optimal powerband.
- Longevity: With proper maintenance, the engine can last a long time, with some owners reporting them reaching 300,000 miles.
Cons
- Maintenance is crucial: The engine requires diligent maintenance, such as regular oil changes and coolant flushes, to last a long time.
- Older generation issues: The first generation of the 3.5L EcoBoost was more prone to carbon buildup on the intake valves and some cam phaser issues.
- Potential for leaks: Some users have reported oil pan and coolant hose leaks, along with potential exhaust manifold leaks.
What to know before buying
- Maintenance history: When buying a used model, check the maintenance history. A well-maintained engine will likely provide better performance and longevity.
- Model year: Newer generations of the engine (like the second generation of the 3.5L EcoBoost) have fewer common problems than the first generation.
- Engine noise: The engine can be a bit noisy compared to a naturally aspirated engine, although some find the sound enjoyable.
