What is the horsepower rating of the 3.5 L EcoBoost V6 engine on XL Stx and XLT Expedition?
The 3.5 L EcoBoost V6 engine powering Expedition XL, STX and XLT trims generally delivers 375 horsepower in newer model years, with earlier versions rated at 365 horsepower. This article breaks down the numbers and what they mean for these specific trims.
The Expedition’s lower-to-mid trims share the same EcoBoost heart, but Ford’s tuning has evolved over time. Below is a concise look at how horsepower has trended across model years for these trims, along with practical notes for buyers.
Engine horsepower by model year
To understand what you might expect in terms of power, review the typical numbers tied to the 3.5L EcoBoost in Expeditions within these broad windows.
- 2015–2016 Expedition: 365 horsepower (with about 420 lb-ft of torque)
- 2017–present Expedition (including XL, STX and XLT): 375 horsepower (with about 470 lb-ft of torque)
These figures reflect Ford’s published ratings for North American Expeditions and can vary slightly by market, calibration, or special editions. Always check the window sticker for the exact specification on a specific vehicle.
Model-year caveats and regional variations
The numbers above cover the typical configurations you’ll encounter in the XL, STX and XLT trims. If you’re comparing a used model or regional editions, verify the exact horsepower on the sticker, since a late-2010s Expedition might list 365 hp while newer units list 375 hp.
Practical impacts for buyers
XL, STX and XLT are the entry-to-mid level trims in the Expedition lineup. Their power output aligns with Ford’s broader EcoBoost tuning rather than with special-performance variants. For most buyers, the 375 hp rating (2017 onward) provides ample acceleration for a three-row family SUV, while the earlier 365 hp configuration still delivers solid capability for daily driving and payloads.
Summary
Across the Expedition’s XL, STX and XLT trims, the 3.5L EcoBoost V6 has shifted from 365 horsepower in the mid-2010s to 375 horsepower in more recent years, with torque rising from about 420 to 470 lb-ft. For shoppers and current owners, the model year is the key determinant of the exact horsepower figure, not the trim level itself.
