Honda Civic 1.0L 2021 - Underpowered?
Discussion
I am considering selling my 8th generation Civic to buy this:

Downgrading from 1.8L to 1.0L. I'm concerned it will be underpowered.

Its got a wet belt. £1600 to replace every 6 years 75k miles, what ever is sooner. Lots of reports across the web of premature failure at 40k miles lunching the whole engine, although Honda do step up for cars with a full Honda service history.
Early 1.5 turbo’s had oil dilution issues.
I briefly considered buying a Mk10 Civic but realised these aren’t the reliable Honda’s of old.

My inlaws had a 1.0T wet belt failure last year, fortunately engine replaced under warranty (after the whole "you need to pay us £x thousand just to diagnose it and we'll refund if it's a wet belt induced problem" b
ks...)
Yes it is a stupid design. Belt wears, rubber particles end up in oil, then presumably it doesn't go through the filter before going into the turbo. Turbo oil feed clogged, turbo overheated, lunched itself, metal ended up in the cylinders.

Slight thread revival, but the key points I would want to stress -
Don't go for the 1L If you plan to keep it.
The aforementioned wet belt adds hugely to the upkeep and service costs, with scheduled changes being upwards of £1k
The reliability is poor, thanks again to the wet belt - There's been a number of failures and friends who work in service at Honda have seen a great number of them back for new engines
Finally, The 1.5 has better real world fuel economy, more power, and greater reliability - The oil dilution issues have never reared their heads in Europe that I've seen, and were primarily a north US / Canadian market concern, where people are making short drives in negative temperatures on a very regular basis.
Whatever premium you'd pay for the 1.5 over a 1L will very quickly be made up for by the increased service cost, bork factor and fuel consumption.
