Specs on this page are Ford's published “properly equipped” figures for the current F-150 as of October 31, 2026, or are marked as reported/approximate. Ford had not published full 2027 F-150 specs; we'll update when it does. Your exact truck's numbers are on its window sticker and door-jamb label.

3.5L EcoBoost vs 5.0L V8: which is better?

This is the most-searched F-150 question, and both answers are right for different people.

• 3.5L EcoBoost: twin turbos deliver 500 lb-ft low in the rev range, so it pulls a camper up a grade without winding out. It's the only gas engine that unlocks the top 13,500-lb conventional tow rating (with the Max Trailer Tow package and the right axle). Downside: more parts (turbos, intercooler plumbing), and fuel economy drops sharply under boost.
• 5.0L V8: 410 lb-ft, linear throttle, the sound buyers want, and fewer parts to service long-term. It tows plenty for most boats and mid-size travel trailers, but it makes its power higher in the rev range and won't reach the 3.5L's max rating.

Our rule of thumb: towing more than about 8,000 lb regularly, or living with a camper in summer → 3.5L. Mostly driving, occasional trailer, wants a V8 → 5.0L.

Is the 2.7L EcoBoost enough engine?

For commuting to Rice Lake, hauling mulch, pulling a fishing boat or a utility trailer, yes. The 2.7L makes 325 hp and 400 lb-ft — more torque than the V8 at lower rpm — and is usually the most efficient gas engine in the lineup. Step up only if you tow heavy often, want max payload, or plan to plow with a heavy setup. Tow ratings for 2.7L trucks are lower than 3.5L trucks; check the specific configuration in the towing guide.

How the 3.5L PowerBoost hybrid works — and is it worth it?

PowerBoost pairs the 3.5L EcoBoost with an electric motor sandwiched in the 10-speed automatic. Combined: 430 hp and 570 lb-ft, the most torque in the F-150 lineup. The battery recaptures energy when braking, helps launch the truck, and lets it creep in parking lots on electric power.

• Worth it if: you do a lot of stop-and-go driving, want quick acceleration while towing, or will use Pro Power Onboard — 2.4 kW standard and 7.2 kW optional on PowerBoost, enough to run job-site tools or back up essential home circuits in an outage (with a proper transfer switch installed by an electrician).
• Maybe not if: you mostly drive steady highway miles (the efficiency edge narrows) or need the highest payload — the hybrid hardware adds weight.

Can I still get a V8 in an F-150?

Yes. The 5.0L V8 remains available across core trims including XL, STX, XLT, Lariat and Tremor (availability by trim and model year varies — confirm with us before ordering).

Real-world fuel economy

EPA ratings are on every window sticker. In daily mixed driving, owners commonly report roughly 20–24 MPG from 2.7L EcoBoost and PowerBoost trucks; heavy towing, 4WD use and V8 high-speed cruising often pull that down to about 14–18 MPG. Those are owner-reported ranges, not Ford ratings — tires, axle ratio and Wisconsin winter blends all move the number.

Barron, Wisconsin notes

• Order the engine block heater if the truck sleeps outside; all four engines start better on a plugged-in January morning.
• Turbo engines warm the cabin fast; the hybrid can run the heater from the battery briefly while parked.
• Use 4A/Auto 4WD on mixed snow and pavement; see the maintenance schedule for oil intervals by engine.
