Anyone know why the 2026 Hybrid is rated for 25 fewer HP than the 2024/25?

In the process of looking at getting another Nautilus despite my 25 Reserve 3 being repurchased by Lincoln under the lemon law.
Have been waiting for the 2026 models to come out but then I noticed that in the specifications, the rated combined HP for the 2026 Hybrid is now only 285 hp compared to the 310 of the 2024/25, and I have asked all three of the local dealers here in my area, and none of them were even aware of the difference, let alone know why it is lower.
At first I thought maybe they are rating it this year using regular unleaded instead of the recommended premium, but the disclosures at the bottom show both were rated using premium fuel.
Torque rating remains the same but at 250 lower RPM than in 2025, and the funny item is that somehow the cargo compartment "grew" from 68.8 cu ft to 71.3 cu ft.
Has anyone here heard of why the downgrade to the HP?

Base Premiere (no panoramic roof) cargo is still 71.3 - that's what it's been since '24.

The 68.8 ft3 kicks in when you get the panoramic roof. You'll notice the panoramic roof reduces front headroom by 0.5", rear by 1.4" (0.117'), to handle fitting in the panoramic including its mechanical parts. Reduced headroom directly maps to reduced cargo capacity (including the rear cargo door interior liner lowered at the top to match the main passenger compartment headliner height).

@jaycte stated the hp and mpg was due to adding a gas particulate filter.
