The 2027 Ford F-150 drops automatic start-stop on select configurations and cylinder deactivation on the 5.0-liter V8. Ford has also confirmed a gasoline particulate filter for the 3.5-liter engine for 2027.
These changes give shoppers a reason to look beyond the engine badge. Even among trucks powered by the 3.5-liter EcoBoost, whether start-stop stays or goes depends on the drivetrain.
1. Which 2027 Ford F-150 models lose start-stop?
Ford is removing automatic start-stop from several F-150 configurations for 2027, including every model equipped with the 5.0-liter V8. However, the feature remains on others.
“Start-stop is off 3.5L 4×2, all 5.0L and Raptor. It’s still on the 3.0L, 3.5L 4×4,” Ford truck communications spokesman Daniel Peake said in an email.
Here is the breakdown provided by Ford:
- 3.0-liter EcoBoost: Start-stop stays.
- 3.5-liter EcoBoost 4×2: Start-stop goes.
- 3.5-liter EcoBoost 4×4: Start-stop stays.
- 5.0-liter V8: Start-stop goes across all configurations.
- Raptor: Start-stop goes.
The distinction between two-wheel-drive and four-wheel-drive 3.5-liter trucks matters for anyone ordering specifically to avoid the engine shutting off at a stoplight. Choosing the engine alone does not settle the question. Ford did not explain the reason for that configuration split in its email.
2. The 5.0-liter V8 drops cylinder deactivation
The 2027 F-150’s 5.0-liter V8 also loses cylinder deactivation, giving V8 shoppers another change beyond the removal of automatic start-stop.
These are separate systems. Automatic start-stop temporarily shuts the engine off when the truck stops. Cylinder deactivation stops combustion in selected cylinders under certain operating conditions while the engine continues running.
We reported on Ford adding cylinder deactivation to the 2021 F-150’s V8. For 2027, the engine moves away from that feature.
Ford is also expanding V8 availability. The 5.0-liter returns to King Ranch and Platinum for the first time since 2023, with output listed at 400 horsepower and 410 pound-feet of torque in Ford’s 2027 announcement.
That gives shoppers more opportunities to pair a naturally aspirated V8 with a higher-trim truck. Removing these systems alone, however, does not establish how real-world fuel economy or long-term reliability will compare with previous models.
3. Ford confirms a gasoline particulate filter for the 3.5-liter
Ford has confirmed that the 3.5-liter engine has a gasoline particulate filter for the 2027 model year.
“Yes, 3.5 has the particulate filter,” Peake said in an email.
A gasoline particulate filter captures particles in the exhaust. Ford’s explanation of the technology describes a regeneration process that clears accumulated particles, with operation depending on driving conditions.
The email does not specify whether fitment varies by emissions certification or whether it covers every 3.5-liter application, including PowerBoost and the high-output Raptor engine.
We already reported on GPFs and lower horsepower ratings for the 2026 F-150. The 3.5-liter EcoBoost dropped from 400 to 382 horsepower, while the PowerBoost hybrid dropped from 430 to 420 horsepower. Those are reductions of 18 horsepower and 10 horsepower, respectively. Published peak torque stayed at 500 pound-feet for EcoBoost and 570 pound-feet for PowerBoost.
| F-150 engine | 2025 horsepower | 2026 horsepower | Change | 2025 / 2026 torque |
|---|---|---|---|---|
| 3.5L EcoBoost V6 | 400 hp | 382 hp | 18 hp lower | 500 / 500 lb-ft |
| 3.5L PowerBoost hybrid V6 | 430 hp | 420 hp | 10 hp lower | 570 / 570 lb-ft |
Ford’s 2026 towing guide confirms the lower horsepower figures and unchanged peak torque. Ford’s 2027 announcement also lists 500 pound-feet for the 3.5-liter EcoBoost and 570 pound-feet for PowerBoost. Peake’s email confirms the filter for 2027; it does not announce another output reduction or quantify how much of the earlier horsepower change came from the filter itself versus associated calibration changes.
4. What else is changing on the 2027 Ford F-150?
These engine updates are part of a broader refresh for the 2027 Ford F-150. Other announced changes include:
- New base engine: A 3.0-liter EcoBoost V6 replaces the 2.7-liter.
- More V8 choices: The 5.0-liter returns to King Ranch and Platinum.
- BlueCruise with Towing: Equipped trucks gain hands-free, eyes-on highway driving while pulling compatible trailers.
- Lower-priced off-road options: New entry-level Tremor and Raptor equipment groups retain core off-road hardware while reducing comfort and convenience features.
- Updated styling: XLT, Lariat, King Ranch and Platinum receive new grille and wheel designs.
- First F-150 Carhartt: A new package brings distinctive exterior details and workwear-inspired interior finishes to the XLT 4×4 SuperCrew.
The PowerBoost hybrid and available 7.2-kW Pro Power Onboard system also continue in the lineup.
