Will the 2019 Subaru Boxer 6 cylinder flat engine last as long as the 2019 V-6 in the Honda Passport and Pilot?

We won’t know for a few years.

Maybe, maybe not. Too many variables to consider but both should go over 200K miles with the proper maintenance.

Subies in general have had more problems with oil burning, leaking valve covers, and blown head gaskets, compared to Hondas in general. I can’t speak to the specific engines you cite.

They will both last a very long time, but the Honda engine will do so with less maintenance and repairs. Proper care is the key and 300,000 miles is easily achieved diligent care and sane driving.

other than blown headgaskets (which did not affect Subaru’s I-6), I have to agree with @shanonia that Subaru will probably burn “some” oil to compare to Honda, but both engines will likely be OK longer than the car itself

The Subaru Boxer 6 should be competitive in longevity to any engine out there. I have owned a 2010 boxer 6 and now drive a 2015 boxer 6. The 2010 used a very little oil between changes, the 2015 at 100,000 miles is not using any oil between changes. I use Mobil 1 that is advertised to be good for 15…

The owner’s manual for my 20 year old Corolla says that you need to check your oil level because it could eventually burn some oil.It doesn’t after all this time.

XT models turbo engines will be a headache I can predict.

There hasn’t been a turbo (XT) Outback for the U.S. Market in about a decade. The OP is asking specifically about 2019 models.
The turbo 2.5L has proven to be more reliable than the N/A 2.5L in previous models. It doesn’t have the the same propensity for blowing head gaskets.
