Is that opposed to a "Half" Hybrid? Never heard of that until now. But sure enough, Ford calls it a "full" hybrid. Just marketing speak?
Anyway, my brother is looking at a 2024 F150 XLT "Full" hybrid. Any of you guys have one ? Problems? Mileage? Power?

 

The only hybrid in F-150 clothing is the Powerboost and I would classify it, in my lingo, as a "half hybrid" because the engine needs to be running to charge the batteries and it cannot travel any significant distance without the internal combustion engine. I would consider a plug-in hybrid to be a "full hybrid" because it can be charged plugged into a wall socket while sitting in the garage and can actually run a substantial amount of time in electric mode only.

Edit: (I know mine are not the correct definitions)

The Powerboost, at its best, will average low to mid-20's mpg (mine has averaged 19.5 mpg over 40,000-plus miles) but it has plenty of power since it is essentially the 3.5 liter EcoBoost engine with a 40 hp electric "kicker" motor added on. Mine gets up to freeway speed very quickly when pulling my 6000 lb travel trailer. Some owners have had issues with the extra heating/cooling system required for the electric motor and hybrid battery but not all that many. Mine has been flawless, so far, and the only issue I had with my truck (other than the few minor recall issues) has been a leaking rear diff seal at 28,000 miles that was covered under warranty and not related to the hybrid power train.

I ran an unscientific poll of Powerboost owners in another forum just to see what owners were getting for mileage long term and out of 120 responses, 30% were greater than 23 mpg, 20% were less than 20 mpg, and 50% were in the 20-23 mpg.

 

Full Hybrid - the engine is still considered the primary power source for propulsion. The electric motor may provide assistance or be used as the sole source of propulsion for certain conditions (i.e. low-speed or light acceleration). For the F150, this just refers to the Powerboost.

Mild Hybrid - engine is still primary. Electric motor just provides a bit of boost when accelerating from a stop.

Plug-in Hybrid - just means that the hybrid battery may be charged by an external source, instead of solely by the engine.

You may find that some sources use slightly different definitions. Here is the government's answer:

Here's the window sticker for the truck he's looking at.`
I'm a 5.0 guy, and through my own ignorance, I'm not even sure what a Power Boost is.

 

Thanks guys, that explains it to me. I'll bet you can really feel that extra 40hp at WOT.
Here I thought the power boost had something to do with that 7.2kw power supply.
I'm under the impression that "Full Hybrid" moniker is just marketing speak.
So the 40hp motor isn't actually powering the truck at cruising speed?

 

It does still supplement the ICE at cruising speed which is why it has better rated highway fuel efficiency than the 3.5 EcoBoost. Also, I believe I saw a YouTube test (maybe TFL Trucks) where they raced a Powerboost against the Raptor w/3.5 Liter HP (not Raptor R) and the Powerboost outperformed the Raptor by a small amount.

 

I thought it just requires a plug and cannot be charged by engine. [Edited: Found that one to be untrue, can be charged by ICE]

And that half-hybrids are just weak hybrids, no difference with full hybrids. [Edited: Found that one to be also untrue]

 

Haha...that's why I said "my lingo"... I liked Hatallica's response as far as definitions.

 

That extra heating system is for faster cabin heating during winter. Heat exhaust exchanger. The same part was used on Mavericks and caused the exact same issue on them.

There is no extra cooling for the electric motor as that is built into the torque converter.

The Powerboost is a parallel hybrid meaning the ICE and battery blend power together to move the vehicle. It is a full hybrid. No other name to really call it.

 

I have a 2023 PW with just under 13K miles on it and I love it. The engine does not run in some instances (slowing down, driving around neighborhoods at 25 mph, etc). It has a ton of power, and if you are light-footed on your right foot, the MPG is really impressive. I just got 23 mpg on a 2500 mile road trip last week, and averaging 21 mpg over all.
