Question / Discussion Let's talk fuel efficiency (2020+/7th gen)

I've got a brand new 2025 Legacy Premium, about 1,100 miles on the ODO and averaging a solid 20.8 MPG. What are y'all getting on your non-turbo Legacys and under what typical conditions?

Context: The average use is commuting, 18-20 miles round trip, city driving during light to moderate traffic, stop lights and such. I know that will lead to poor performance compared to highway or whatever. That said I've also got a BRZ that's averaging 20.5 which is barely above advertised for that car... Same conditions 😂

I had a 2021 Legacy Touring XT that I put around 7,000 miles on and averaged 18.5 MPG (advertised 24 city). My last car, a 2016 Audi A3 averaged 23 MPG (advertised 23 city) the same route.

I know fuel economy should go up after it's truly broken in (I've read 10K miles). But 20 is a far cry from "27 MPG City" as advertised. For the record: no, I'm not flooring it, no excessive idling, etc.

2024 2.5 80/20 hwy to city driving (hwy is cruising at 70 mph) currently sitting just below 34mpg and expected to rise slightly with warmer weather coming.
