EcoBoost vs PowerBoost: Comparing Engines

What Is a Ford EcoBoost Engine?

EcoBoost is Ford's name for its turbocharged, direct-injected gas engines. Use a smaller engine, add turbochargers, and you get the output of a larger one. A 2.7-liter V6 that makes 400 lb-ft of torque is doing work that used to require a V8.

The name covers a whole family, spanning a 1.5-liter three-cylinder in the Escape up to the 3.5-liter V6 in the F-150 and Expedition. Every one of them burns gasoline only, with no electric motor and nothing to plug in.

In the F-150 you will see two of them on the window sticker: the 2.7L and the 3.5L. The Raptor gets a High-Output version of the 3.5L rated at 450 horsepower and 510 lb-ft.

What Is the Ford PowerBoost Engine?

PowerBoost takes the 3.5L EcoBoost V6 and adds a 35-kilowatt electric motor, worth 47 horsepower, built into the 10-speed transmission, along with a 1.5 kWh battery under the rear seat. Ford calls it a full hybrid, which means it charges itself through the engine and regenerative braking.

The combined output is 430 horsepower and 570 lb-ft of torque, the most torque in any F-150 short of the Raptor R. The electric motor delivers its share of that instantly, which is what you feel pulling away from a light or merging onto I-64 with a trailer behind you.

PowerBoost remains exclusive to the F-150, and has been since it launched on the 2021 model. For 2026, Ford expanded it to more trim levels than before.

Fuel Economy

The hybrid's advantage is real, and it is concentrated almost entirely in city driving.

EPA ratings for the 2026 F-150. A 2WD PowerBoost rates higher still, at 23 city and 25 highway.

Five mpg in town is a genuine gap, and it exists because the hybrid shuts the gas engine off entirely at low speed and recovers braking energy. On the highway the advantage shrinks to a single mpg, since a hybrid has little to recover at a steady 70 mph.

What that means in dollars: at 15,000 miles a year, 23 combined mpg versus 19 saves about 137 gallons annually, or roughly $410 at $3.00 a gallon. If your miles are mostly Manchester Road and school runs, you capture the full benefit. If you commute to Columbia twice a week, you capture almost none of it.

Our guide to improving F-150 gas mileage covers what you can control regardless of engine.

Power and Torque

PowerBoost wins both, at 430 hp and 570 lb-ft against 400 hp and 500 lb-ft. The electric motor supplies its torque immediately rather than waiting for turbos to spool, so the hybrid feels stronger off the line, under load, and backing a boat up a ramp. Once you are moving, the two are hard to tell apart.

Pro Power Onboard

PowerBoost comes with Pro Power Onboard as standard equipment: 2 kW of electrical output through bed outlets, with a 7.2 kW system available.

At 7.2 kW you are running a miter saw and a compressor at the same time on a job site, or keeping a refrigerator, a furnace blower, and lights going through an Ameren outage. Our guide to using an F-150 as a backup generator walks through what it will and will not run.

The Full F-150 Engine Lineup

Where Else Ford Uses EcoBoost Engines

PowerBoost is F-150 only. EcoBoost is everywhere:

• ✓
  1.5L EcoBoost: Escape, Bronco Sport, Maverick
• ✓
  2.0L EcoBoost: Escape, Bronco Sport
• ✓
  2.3L EcoBoost: Explorer (300 hp), Bronco (300 hp), Ranger (270 hp), Mustang (315 hp)
• ✓
  2.7L EcoBoost: F-150, Bronco
• ✓
  3.0L EcoBoost: Explorer ST and Tremor (400 hp)
• ✓
  3.5L EcoBoost: F-150, Expedition, Transit

Output varies by vehicle even within the same displacement, because Ford tunes each application differently.

So Which Should You Buy?

• ✓
  Choose the 2.7L EcoBoost if the truck is primarily transportation that occasionally hauls. It tows 8,400 lbs, returns the best gas-only city mileage in the lineup, and costs the least.
• ✓
  Choose the 3.5L EcoBoost if you tow heavy or haul heavy. Nothing else in an F-150 pulls 13,500 lbs or carries 2,440 lbs of payload. This is the engine for the big camper, the equipment trailer, the loaded bed.
• ✓
  Choose the 3.5L PowerBoost if your miles are mostly local, or if you need power at the job site. You get the most torque in the lineup, five more city mpg, and a 7.2 kW generator in the bed. You give up roughly 1,900 lbs of towing and 700 lbs of payload against the 3.5L EcoBoost, and you pay more up front.
