Hello everyone, I would like to ask your important opinion about a purchase.

I found from a private person both a used 2020 Fiesta mild-hybrid 1000cc 125hp with 70,000 km and a used 2018 Fiesta 1.4 95hp LPG with 50,000 km. Both cost 12,000 euros.

I would like to buy one of them but I have some doubts:

1) I drive 60km per day (definitely less than 20 thousand km per year) in urban/extraurban road (no highway!) and I almost never exceed 100 km/h (I hate speed!) .. which one consumes less?

2) In the case of the hybrid ... are 70,000 km too much? I want to buy a car that will last at least 200,000 km ... do you think the hybrid will make it?? (I am convinced that the 1.4 (four-cylinder) of the LPG Fiesta is more reliable and lasts much longer than the 3-cylinder of the hybrid ... it seems to me that 125hp for 1000cc are too much)

3) Which of the two might have more maintenance costs? ..I don't know anything about maintenance and issues of the hybrid!

 

Hi,

This forum is mostly UK owners and we have very few LPG cars in the UK nowadays so it's going to be difficult to compare those two cars.

1) The MHEV will most likely consume around 10% less fuel in those conditions.  BUT, we would need to know the cost difference between LPG & petrol in your location for a financial comparison.

2) No, 70k km is not too much.  I see no reason why the MHEV wouldn't make 200k km as long as it is serviced regularly with the correct oil.  It is true the 1.4 engine has less to go wrong and has been around a lot longer.  However I disagree that 125bhp is too much for a 1.0 nowadays.  150bhp+ is easily achievable, with 170bhp as standard from the factory in the new 1.0 Puma.

3)  There are no additional servicing costs for the MHEV compared to the standard 1.0.  The only extra on the MHEV service is that the generator (alternator) belt should be replaced every 4 years, as that takes more strain on the MHEV, but it is cheap and easy to do so shouldn't be a concern.  I am unsure if there are any extra costs for LPG servicing.

The 1.4 engine uses a rubber cambelt which should be replaced every 8 years.  The MHEV engine uses a camchain which does not need replacement.  However, it has a small belt for the oil pump which should be replaced every 10 years.  The cost for the oil pump belt change is much higher than the 1.4 cambelt change.

 

Hopefully that's some help, though as I say, very few LPG cars on here so difficult to comment on that.

Ciao

Questo forum è composto principalmente da proprietari del Regno Unito e al giorno d'oggi abbiamo pochissime auto a GPL nel Regno Unito, quindi sarà difficile confrontare queste due auto.

1) L'MHEV molto probabilmente consumerà circa il 10% in meno di carburante in quelle condizioni. MA, avremmo bisogno di conoscere la differenza di costo tra GPL e benzina nella tua posizione per un confronto finanziario.

2) No, 70k km non sono troppi. Non vedo alcun motivo per cui l'MHEV non dovrebbe fare 200k km purché venga revisionato regolarmente con l'olio corretto. È vero che il motore 1.4 ha meno da sbagliare ed è in circolazione da molto più tempo. Tuttavia, non sono d'accordo sul fatto che 125 CV siano troppi per un 1.0 al giorno d'oggi. 150 CV+ sono facilmente raggiungibili, con 170 CV di serie dalla fabbrica nella nuova Puma 1.0.

3) Non ci sono costi di manutenzione aggiuntivi per l'MHEV rispetto allo standard 1.0. L'unico extra del servizio MHEV è che la cinghia del generatore (alternatore) deve essere sostituita ogni 4 anni, in quanto ciò richiede uno sforzo maggiore per l'MHEV, ma è economico e facile da fare, quindi non dovrebbe essere un problema. Non sono sicuro che ci siano costi aggiuntivi per la manutenzione del GPL.

Il motore 1.4 utilizza una cinghia a camme in gomma che deve essere sostituita ogni 8 anni. Il motore MHEV utilizza una catena a camme che non necessita di sostituzione. Tuttavia, ha una piccola cinghia per la pompa dell'olio che dovrebbe essere sostituita ogni 10 anni. Il costo per la sostituzione della cinghia della pompa dell'olio è molto più alto rispetto alla sostituzione della cinghia a camme 1.4.

 

Spero che sia un aiuto, anche se, come ho detto, pochissime auto a GPL qui sono così difficili da commentare.

Thank you first of all for your reply.

Unfortunately, I realized that in my main post I wrote "used 2018 Fiesta 1.4 95cv LPG with 50,000" when I actually meant "used 2018 Opel Corsa 1.4 95cv LPG with 50,000 km" ... sorry, I got confused. So I don't know if we can make a "comparison" between the two cars since this is a Ford forum and not Opel.

Regarding prices: gasoline is 1.863 €/l and LPG is 0.726 €/l

I know that since the cambelt runs in the engine oil .. this degrades the belt after a period of time, the rubber filings in the belt clog up the oil pick up pipe, and the fine filter for the oil feed to the turbo, starving the turbo and engine of oil, causing engine failure. So ti's raccomanded to change the oil every 5/6k miles, using the correct grade of oil. Are you aware of this? Do you agree with it?

Again, thank you for your response and your time!

With LPG being so much cheaper than petrol, the LPG car will definitely be cheaper to run.

Unfortunately I don't have any experience with modern Opel's (branded as Vauxhalls over here) but there is no forum rule against discussing other cars so others may be able to comment on that.

Regarding the cambelt in oil, that is not present on the MHEV engine.  The MHEV uses a newer version of the 1.0 engine with a metal chain instead of a cambelt.  It is only the small oil pump belt that is in oil on the MHEV engine.  It is still worth using the correct oil and changing it regularly.  As it looks like you'll be doing around 20,000km a year, I would say an oil change every 12 months should be fine with your usage.

Poiché il GPL è molto più economico della benzina, l'auto a GPL sarà sicuramente più economica da gestire.

Purtroppo non ho alcuna esperienza con le Opel moderne (marchiate come Vauxhalls qui), ma non c'è alcuna regola del forum contro la discussione di altre auto, quindi altri potrebbero essere in grado di commentare su questo.

Per quanto riguarda la cinghia a camme in olio, questa non è presente sul motore MHEV. L'MHEV utilizza una versione più recente del motore 1.0 con una catena metallica al posto della cinghia a camme. È solo la piccola cinghia della pompa dell'olio che è nell'olio sul motore MHEV. Vale comunque la pena usare l'olio corretto e cambiarlo regolarmente. Dato che sembra che farai circa 20.000 km all'anno, direi che un cambio dell'olio ogni 12 mesi dovrebbe andare bene con il tuo utilizzo.

1) It is not clear to me whether the Ford Fiesta 2020 mild ibryd 999cc 125hp uses a cam or metal chain.

2) So, if I understand you correctly, the main maintenance for the mild-hybrid you mentioned is:

- generator (alternator) belt should be replaced every 4 years, as this requires more effort for the MHEV, but it is cheap and easy to do, so it should not be a problem

- small belt for the oil pump (it is in the oil!) which should be replaced every 10 years

- 48V battery when it will run out

Did I make a mistake/confuse/forget something?

1) All Ford 1.0 mild hybrid are the newer EcoBoost engine which uses a metal chain between the camshaft and crankshaft.  However, they also still use a small wet belt just to run the oil pump.

2)  Correct.  Generator belt every 4 years.  Oil pump belt every 10 years. 

Other servicing is the same as the non-hybrid 1.0 - Oil & filter every 1 year (although Ford say every 2 years).  Spark plugs & air filter every 4 years.

So far I have not seen any 48v battery need to be replaced.  As they are only now 4 years old we do not know how long they will last.  There is no recommended replacement for them in the servicing schedule, so they are not expected to break at a specific age or distance.
