4x4 ta, mpg question

I had my car serviced (by fiat) 2-3 weeks ago. Since then my ave mpg has dropped from mid 40's to mid 30's. I don't think my driving has altered at all. Could this and the recent service be connected? Any thoughts?

Re: 4x4 ta, mpg question

Could it be because the air con was working harder during that very hot spell a week or so ago?

On a related theme, I had to make my regular 65 mile commute at a brisker-than-usual pace last week (all but 3 miles on uncrowded dual carriageway, mainly in 6th, and nothing above an indicated 77). I reset the trip at the start, and my mpg for the journey was 31. That's a new low for me. At that pace, my old DS3 (petrol turbo, 155 hp) would have comfortably given over 40.

I would have hoped the aircon (climate control) would not make that much difference but I'll put it to the test this week on a longer trip to include motorways...

Re: 4x4 ta, mpg question

Hi all, have began to wonder how much MPG difference there is between the twin air and the MJ engines. I have never driven a twin air, but a lot of the Fiat salesman have steered me away from them, mainly because of poor MPG. The best mpg I have had is from a Mk 3 MJ Panda, always 50-60 mpg. The 4x4 2013 MJ Panda I had was mainly 45-47 and maybe 50-55 if I had a longer trip and kept the speed down. So looking at previous posts on twin air mpg seemed that 40-50 mpg is the norm, obviously this should be better in each case for non 4x4's. I have never found air con making a great deal of difference. But I do think the MJ may be better suited to the 4x4's mainly for off road driving. I will test drive a twin air one day,as they sound excellent and exciting to drive.

Re: 4x4 ta, mpg question

I have had 46 out of the Cross MJ with about only 150 miles on it, so a lot of running in to do yet, and will be interesting to see if the small increase in bhp will make a difference to.

I wouldn't mind other than it seems to have plummeted since its service....

Re: 4x4 ta, mpg question

Sorry for wavering off topic Triumph, I think a call back to the dealers may be the key, if anything performance and mpg should be maintained with good servicing, so a drop in mpg would be concerning. Like I said previous I don't think air con would make a vast difference, as I think you would have noticed before, good luck with it, and keep updating if you get a solution 👍

Re: 4x4 ta, mpg question

triumph7 - have they adjusted-up your handbrake a little tight? Any drag could create problems.... Otherwise, the only thing they could potentially have done is uploaded a new fuelling map, but you'd expect that this wouldn't be rolled out if it reduced economy. And there'd be more folks grumbling about it!

Air-con definitely dents economy figures, especially in smaller engines. Even on our other car, a 200bhp 2.2 diesel, leaving air-con/climate control on will knock 2-3mpg off on a steady motorway run! On smaller cars the power drawn is proportionately higher, so may be even more noticeable? I have air-con off unless it's really needed, at which point I accept the loss in economy! (Phew! Scorcher!)

Re: 4x4 ta, mpg question

I'm assuming you didn't have any accessories fitted (eg. Roof bars), the drag from those can knock off a couple of mpg if they're not the WingBars/Whispbar variety....

No accessories! To be honest its mainly just country road driving most of the time and I've been averaging 43-46, but its now indicating 33! I really don't think the aircon is going to make that difference. I think I might 'have a word'....

Re: 4x4 ta, mpg question

This thread has quite a few comments on the aircon's effect on mpg:
https://www.fiatforum.com/panda-iii/...air-mpg-6.html
including my observations with/without the aircon on at a steady 70mph.

Driving for about 20 minutes at close to 70 mph, with the aircon on, fan speed 2 and windows closed, gave about 49 mpg.
Driving for about 30 minutes at close to 70 mph, with the aircon off, fan speed 2 and windows closed, gave about 55 mpg.
These mpg figures varied with uphill and downhill stretches, so they are not exactly comparable, but they indicate about a 10% effect on mpg at 70 mph, due to the aircon.

I have to say that I was surprised that the difference was so high. I have not seen any significant effect with the AC on the Multipla (although this is a 1.9 JTD).

The test was with a TA Lounge, not a 4x4, with 1600 miles on the clock.

Re: 4x4 ta, mpg question

I'm sure that aircon has relatively little influence on mpg. I generally get just under 40 - say 38 mpg and this is with or without aircon doing its stuff. However, I do suspect the effect is slightly offset by the fact that I tend to have the aircon working harder when the ambient temperature's higher as this seems to have a noticeable beneficial effect on the TA engine's thirst.
