Define " a lot better " ?

The FB25 has more bore (it's oversquare), more displacement, 0.5 less compression, more torque, more horsepower. Same engine block, same cylinder wall thickness, same pretty much everything else. 2.0 uses a conventional thermostat, 2.5 uses a thermo control valve. From a purely thermal perspective, the 2.0 will be less prone to overheating (same cooling system for 20% smaller displacement), however none of them are known to overheat... so it's a moot point. Head gaskets are not an issue on the FB2xD series, neither there are any concerns about engine reliability for either variiants. The FB series has been used since 2011, it's proven.
What about oil blow by past the cylinders on the more recent (late year) FB series engines? Don't know if I'd call it "proven". The tolerances are not as tight as they used to be to increase fuel economy so my question is whether these engines will pull 300k or more because of the changing oil consumption. Seems like everyone getting a short block done after 150k.

i have driven 110k miles in a 2016 with 2.0L and 55k miles in a 21 sport which of course has the 2.5L. i have driven both extensively in extreme conditions. the 2.5L is a lot better. it is afterall a 20% increase in hp from one of the weakest 4-bangers on the market
What's the real-world fuel economy difference of the 2.5L vs. the 2.0L? Specially with colder climates and warm up?
 
I wouldn't write the Mazda off, I really like them. The reason I chose the Crosstrek over a Mazda was the AWD system, and I really like the rugged low maintenance interior of the Sport. I use mine to access a lot of off road areas and often have my dog or other dirty gear on the back. The capability of the AWD and ease of cleaning the interior were my selling points. If those aren't important to you I would look hard at the CX30. I honestly think it is more comfortable, feels more refined, and handles great! In my experience other than their rotaries Mazda's have been very reliable.

very little difference, if any. i noticed no difference. peruse fuelly for an idea what others get 2021 Subaru Crosstrek MPG - Actual MPG from 238 2021 Subaru Crosstrek owners

"I chose the Crosstrek over a Mazda was the AWD system" many of us choose crosstrek because of AWD. that's why i can't understand why other brands like mazda, BMW, chevy, lotus are often interjected in non offtopic posts

I'm not sure I follow your post. The OP mentioned the Mazda CX30. It is an AWD in direct competition with the Crosstrek.

Our Mazda 3 hatchback was a part time AWD. Had very poor clearance so never got driven in snow. Other than an a useless back seat and access, as well as a bizarre head unit that wasn’t, it was an OK car. Had a long nose and was hitting our driveway entrance everytime, that was a PITA. I prefer driving the Crosstrek personally.
 
OT

A brief comparison by a passionate hunter from Europe between the Crosstrek and the Mazda CX-30.
Both are only available as hybrids in Europe.
The CX-30 is not suitable for me for two reasons:
1) The Mazda has a ground clearance of only 17.5 cm (6.89 inches) compared to 22 cm (8.66 inches) for the Crosstrek.
2) The Crosstrek's all-wheel drive is known for its great reliability and good capabilities even on very muddy or snowy surfaces.
 
Y'all think way too much. Just buy what you wanna buy.
I get your point, but to me, what I want is something that’s the best bang for my buck, so researching and asking questions is what leads to me to what I want. I don’t know what I want till I learn what’s objectively best for my current needs in a vehicle.
 
I had a 2018 MT with the 2.0. I never had any issues with traffic or passing. It did occasionally get pushed to its limits. I now have a 2024 Limited with the 2.5 and feel like I can achieve similar performance without reaching the engine’s potential. I believe the 2.5 is a worthwhile investment. MPG has been similar. I enjoyed the MT, but I prefer the drive ability of the 2.5.

I had the '19 2.0. I got rid of it bc the vehicle was to small and I went back to the Forester. People complain about the lack of power for the 2.o and very very few (I would guess) have ever let it shift on its own at 6K rpms. I did it all the time. Lots of HP up there beyond 4K rpm. I had the 2,5 Forester after that and letting it shift the same way I would have been hard pressed..lol.

I now have the FA 24 unturboed. I would have loved to see the FA20 instead of the FB20 in the XV but that is a pipe dream. That had 200HP
 
I've said in the past that a Mazda is like the pretty but shallow blonde girl in high school ... you'll want to go to the prom with her, but you'd end up hating it if you actually settled down with her permanently. ;)

Even if you don't go off-road, I think there are valid reasons for wanting the Subaru AWD system ... better stability all around, and especially if you are in snow country.

I drove a Crosstrek with the 2.0 for seven years, and it was fine, but after I upgraded to the 2.5 I found it to be quite a bit better, and I'd never go back. I can actually pass cars on two-lane roads without breaking out in a sweat now!

Consumer Reports does say that Mazda tends to have high customer satisfaction.

How is the interior holding up? One thing I'm disapointed on with my 16 Premium is that the interior is showing wear much faster than any other car I've had. At 45,000 miles, I shouldn't be seeing interior parts worn through, and I am?

On a related topic, how's the comfort of the newer seats?

I picked mine up in April of ‘22. I’ve put 55,000 miles on it since then. I clean the interior pretty regularly but have had lots of sand, dirt, some mud, and a Husky in there. It’s a Sport with that vinyl material but still looks like new to me.

As far as comfort these aren’t my favorite seats but they’re not uncomfortable. I’ve done 4-5 hour trips and haven’t had any problems.

I test drove both, and I honestly didn’t notice much difference. Off the line for the most part both engines seem the same. Not sure if the slightly larger engine is worth it. Thoughts?

Also, I wouldn’t want to go to the Limited trim because I don’t want leather. That leaves the sport trim; with the yellow accents. I don’t like them; so I would have them covered or buy all new plastic trim pieces from a Premium and install those.

I’m considering a base model Mazda cx-30. More standard features, and I think better looks; but the Crosstrek looks cool in a different way. I don’t intend to off-road at all; so the AWD system isn’t a big concern for me. I do live on a dirt/stone road; so the extra ground clearance of both is appreciated over a sedan. I live with snowy winters, as well. I really liked the outward visibility of the Crosstrek! If I go with a sport trim, I lose out on the option of the Offshore metallic or sun blaze colors. :(

I’m also concerned about Subaru reliability. It was either Scotty Kilmer or Car Care Nut on YouTube that said Subaru uses silicone sealer instead of gaskets in the engine. The silicone sealer will fail; just a question of when. I do plan on keeping whatever car I choose long term.

Has anyone had major reliability issues with their Crosstrek?

Thoughts? Thanks!
1) When my 2019 Limited was in for scheduled maintenance one time, they let me borrow a loaner that had the 2.5: WAY BETTER. I don't understand how you couldn't have felt the difference, even under moderate driving. I'd buy one but I don't have the money to upgrade and I've only got <17,000 miles on mine.

2) Uh, the leather seats are awesome and not uncomfortable. That's a bad reason to not get all of the extra features that come on the Limited.

3) Don't like the Sport's trim color? Don't buy it. Don't like that you can't get the Sport in offshore metallic or sun blaze? Don't buy it or learn to love another color

4) Don't care about AWD???? Then do NOT buy an AWD car! You're not going to get as good mileage as you do with a FWD (not "4WD") and you'll have a more complicate drivetrain. But, oh! It snows where you live? And is your home under a rock? THEN GET AWD!!!!

5) Modern Subarus don't have reliability issues; in fact, they are highly rated. I don't know where you're getting your info but you need more reliable sources like C&D, R&T and even JD Power.
 
Test drove both engines on the 2024 Crosstrek, went up to the 2.5l tier for a reason. At the very least, I felt a difference... it just felt more "confident" on the highway entrance ramp, when passing the guy going 5 under (who was towing a boat three sizes too big for his luxury SUV), etc...

Also looked at the CX-30, the only aspect on it that really I preferred over the Crosstrek was the non-touch controls for the infotainment center.

E: it does seem a bit odd that the one trim with reduced paint options is the Sport... and I get not liking the leather seats, IME experience, leather or pleather or leatherette seats are very sweaty... on the plus side they tend to be easier to keep clean as long as you take care of them.
 
OP, to answer your question the 2.5 makes a noticeable difference. We test drove a 2.0 and felt very underpowered when trying pass other cars on the interstate.

I REALLY liked the CX-30 and it felt more refined, but the smaller backseat was a dealbreaker for me.
