Ford 3.5L PowerBoost Hybrid Specs, Tow Capacity, and Fuel Economy

Complete Guide to 2021+ Ford F-150 Hybrid Trucks

The 3.5L Powerboost Hybrid V6 isn’t the fully electric F-150 we’ve been waiting for, but it’s close. By combining the 3.5L EcoBoost twin-turbocharged engine with a 35 kW (47 horsepower) electric motor in the transmission, we’ve gotten a more powerful and fuel efficient F-150 than we’re already accustomed to. The Powerboost will debut on 2021 F-150s that also have a new body style, new technology, and even a standard on-board “Generator” feature. These impressive features compliment the performance of the F-150 3.5L Powerboost Hybrid. These trucks leave the lot with 430 horsepower and 570 lb.-ft. of torque. That’s significantly more power the 3.5L EcoBoost on it’s own, however, it falls about 20 horsepower short to the high-output Ecoboost engine in previous models. In this resource article, we’re going to dive into exactly what 3.5L Powerboost Hybrid V6 specs and features are important, and how they impact this new engine’s performance.

3.5L PowerBoost Hybrid Performance

The 3.5L PowerBoost is very similar to Ford’s current 3.5L EcoBoost engine. In fact, it’s basically a 3.5L EcoBoost adapted to work in conjunction with an electric motor. This electric motor is located on the 10-Speed automatic transmission and it’s powered by a 1.5 kWh battery. This battery sits underneath the cab to optimize cab space. This 35kW motor works with the 3.5L EcoBoost engine to provide horsepower and torque. It also captures energy from braking, and supports the generator function available on these trucks.

Pro Power Onboard

One of the most exciting features of Ford’s new F-150 is Pro Power Onboard. It brings a whole new level of versatility to the F-150 by providing owners with generator-like power anywhere the truck is driven. The standard gas engines are available with a 2.0 kilowatt output, while PowerBoost-equipped F-150s come standard with 2.4 kilowatt outputs. Powerboost Hybrid F-150s have an upgraded output option, providing 7.2 kilowatts of output. Power is accessed through in-cabin outlets, or up to four 120V, 20 amp, exterior outlets located in the bed of the F-150. Upgraded output models receive a 240 volt 30-amp outlet too. This is plenty of power to provide work at a job site or camping site. Power is even provided when the vehicle is on the move, a useful feature for charging tools when traveling to different job sites.

Ford 3.5L PowerBoost Hybrid Fuel Economy

Fuel economy hasn’t been computed yet on a miles-per-gallon (MPGs) basis. More detailed and accurate fuel economy information will be released in the coming months. Ford has said that the F-150 with this hybrid engine will be capable of getting at least 700 miles out of one tank. We are very excited to see how the hybrid capability affects city driving. That’s one fuel economy aspect that trucks traditionally struggle with. Assuming a maximum of 700 miles can be travelled on a 30.6 gallon fuel tank, average MPGS for the 3.5L PowerBoost F-150 Hybrid is pegged at around 22.87. That’s a dramatic improvement over the previous ecoboost, although still falling a bit short of the 3.0L Powerstroke Diesel in it’s most efficient variant.
