The real competition in terms of reliability comes from the Pacific Rim, not Europe.
If I were buying a long term keeper, I'd have more confidence in a Hyundai than a Citroen.
Agree entirely in principle if you are being entirely rational...but for some reason the best selling cars are rarely most reliable ones.
Probably because they also tend to be intensely dull. That and Europe has upped it's game to the point that reliability is for most cars the default. If they're all reasonably reliable then that USP disappears...yes you can get a 7 year warranty but who cares if you're on a 3 year lease cycle?
Is assume firefly the 3 and 4 cylinder will be the last petrol engine fitted in any fiat for the next 10 years certainly the last fiat made engine
I would assume it will die when any models fitted with it are replaced. It's likely any new cars designed from this point will be on the CMP architecture, both to reduce production costs and allow electrification and hybrids.
They could spend money re-engineering that to fit a different engine with pretty much exactly the same specs or they could kill the one that doesn't fit 95% of the cars they build as a group. The Firefly does nothing the Puretech doesn't do (other than a 4 cyl variant but the power options are quite similar) so there's no reason they'd run with both into the future.
Regards other markets...Fiat and PSA small cars don't have a huge presence outside of Europe they're even struggling in China currently. All the big Chrysler stuff in America has very little to do with what we get mechanically. Where ever it goes it's unlikely people will be lashing money at new petrol engines (other Mazda who I assume are just planning to be out of business in 2040.)
