Ducato - Going from the 3.0 litre to the 2.3

Hi


We recently changed our 2012 Comanche to a newer 2017 model and are very happy with it however there is a distinct and noticeable lack of oomph from the newer engine. This is especially noticeable on hills or even slight gradients where the speed drops and the dashboard screen advises me to change down. Both MH's are manual and both weigh the same. The older engine claimed 180bhp and the newer one 177 (now PS), I believe. NB the difference between BHP and PS is negligible.


On top of this on our recent trip away we only managed 23.7mpg against a minimum of 27mpg I would have expected with the older 3 litre.


The new one has only just done 5500 miles from new.


So my questions are...


Has anyone else moved from the older 3 litre to the newer 2.3 litre? If so I would welcome your thoughts on the performance you have noticed.

Can I expect better mpg as the engine 'loosens up'? Again, if any folks have had the 2.3 for a while, have you noticed any improvements?


Thanks


Graham

Looking at the toque figures, they are the same too across the older and newer models.


Yes, I'd be interested in your thoughts, thanks.

Pal had his 2.2 litre Autotrail Navajo remapped (a proper remap not a ďplug inĒ gizmo which merely fools the ECU into injexting a bit more fuel) a while back. He reports Much better ďdrivabilityĒ and big improvement in Mpg

Having said that I vaguely recall seeing something in the press that MOT test centres will soon be able to tell if an engine has been remapped (which will be a failure item), plus of course any possible warranty issues with a new vehicle.

Its not the destination that matters.

It's who you share the journey with (even if like me, itís in a caravan!)
I am very fortunate to have Mrs Plodd to share mine with

Know nowt about the old 3lt but my 2.3 2010 130 hp was lacking a little umph on hills .

I did get the plug in version of remap and extremely happy as now flies up hills in 6th and better still returns over 30mpg whereas before was 28.5 avg. not worth jumping for joy over but at least in my favor.

We are running at 2840kg also and on last trip up and down mountains in Switzerland and Germany Ave 30.7 mpg but pulling up hills was great.

I got the plug in so if ever an issue with MOT i could get it out myself. Warranty not valid so not worried about that.

My Fiat 2.3 is coming up to 69,000 miles, had it since new.
Never really had any complaint about hill climbing on reasonable inclines. After all itís a van and a fully loaded van at that.
Now itís finally Ďrun-iní it purrs along all day and responds well to a bit of wellies when itís fully warmed up.
Keep in mind itís not a limo or super-mini, just a fully loaded commercial vehicle.
Anyway, whatís your rush? 🙂

I'm not signing anything.

The two impulses in travel are to get away from home, and the other is to pursue something - a landscape, people, an exotic place. Certainly finding a place that you like or discovering something unusual is a very sustaining thing in travel.
