What is the engine model of the 2.5L in the hybrid?

I do not have full confidence in this answer, but every source I’ve found says it’s model 993.

The hybrid itself is HF45 for 22-24, and HF55 for 25+

I think it's the same 99Z engine for the last iteration of the Escape Hybrid. As you mention, the power-split transmission was initially upgraded to the HF45 and again upgraded to the HF55 in 2025.

It's extremely difficult to find detailed information or commentary on the engine itself. I take this as a reflection of unobjectionable it is. There's no wet belt (or any belt!), no turbo, and no direct injection to worry about. It's a refinement of the best variant of an extremely mature platform (Mazda L5-VE). Aside from the occasional issues with coolant leaks during the Dex-Cool (orange coolant) years (2011-2019), this family of engines has been basically bullet-proof with only standard maintenance. It's probably not quite as efficient as the cutting-edge Toyota Atkinson cycle engines, so we don't see the same kind of buzz about it, but it's still extremely efficient while being pretty much the simplest engine available.

It is an Atkinson cycle, are you saying that it's just not as good as the Toyota version?

Good is relative and subjective. The new Toyota Atkinson engines use Dual Injection and other modern tricks. I'm confident that they have higher thermal efficiency than the Maverick engine. But the efficiency gap is certainly not very big, and there is a LOT to be said for using a slightly less optimized engine that has an extremely mature and known to be reliable design!

For instance, I'm extremely confident that I'm not going to have injector or head-gasket issues as long as I'm not an idiot. I could not be so confident with a Toyota "Dynamic Force" (or whatever) engine. That's not to say the Toyota engines will be unreliable, but this Ford engine has an long and extremely good history that gives me comfort.

I looked under the hood of my maverick and It seems that I have 8 cylinders Marked 6.7 and it smells like diesel

There is a sticker under your hood indicating the engine model….

My 2025 EB says SFMXT02.02Y3 and google tells me:

Engine Type: 2.0L Turbocharged Inline-4 (EcoBoost / MPC engine with port fuel and direct injection)

• Horsepower: ~238 hp
• Torque: ~275 lb-ft
• Emission Classification: Gasoline engine without a Gasoline Particulate Filter”

My 2023 hybrid. I don't see a particular model number.

The engine code you googled is what I called “engine model”. Confusing choice of words by me oops.

The code indicates that it was “primarily used in 2023” Mavericks. Don’t know how or if 2022 or 2024+ are any different in anything but name…

So yours is basically the same sticker, shown in my picture.

The stickers between the EB & Hybrid differ in engine “group” and “evap” system.

The EB engine has undergone a redesign since 2022 - but I think the OP and yourself and all Hybrids up to present have the same Atkinson. Per google:
“Engine Overview

Engine Family: Duratec 25 (Inline-4, DOHC)

• Valvetrain/Cycle: iVCT (Independent Variable Cam Timing) Atkinson-cycle
• 
  
• Applications: Found in modern hybrid variants including the Ford Escape Hybrid/PHEV, Ford Maverick Hybrid, and Lincoln Corsair Hybrid.
• 
  
• Identification: Can be precisely verified via the 8th digit of the VIN or the barcode label on the timing cover. [1, 2, 3, 4]

That wasn't my question.

Great discussion.

I really like the 2.5L Atkinson-cycle on the Hybrid application. The thermal efficiency is superb and the torque of the electric motor to launch and some acceleration works great.

Am optimistic this will last for 300k+ miles by keeping up with maintenance.

I did not understand your question sorry. I did not help answering the OP’s question either. Just a useless EB owner in a Hybrid thread - I’ll leave now

Where was the label located in your engine compartment that you got your information from on your EcoBoost?
