Sport mode v eco mode

Is there any real difference in fuel consumption between sport mode and normal eco mode on the 1.4 Multi Air?

I thought I would try Sport mode the other day for the first time and was surprised how quick it was. Turned it back to eco though as I didnít want to waste petrol.

Iím wondering if there is really any real difference.

Re: Sport mode v eco mode

I can't really comment on the petrol version as mine is the 2.0 Mj. The first time I thought it had increased consumption considerably but now I think that was my exuberance. When I tried it over 80-100 miles in a single journey it didn't seem to make much difference, but it did make overtaking a hell of a lot easier. On the Auto model it seems to be programmed to keep the rpm at 2000 regardless, thus eliminating turbo lag. There are other things too but nothing to put me off using it again

Re: Sport mode v eco mode

Eco cannot change the combustion efficiency.
Eco reduces the response of the throttle, so you need to push further to get the same power. It just encourages the driver to be smoother and more gently with acceleration. If you can drive just as gently in Sport mode, you'll get the same economy. But in sport mode, the extra response is intoxicating, so it gets used.

Eco mode was great on the Fiesta for the learners.

Re: Sport mode v eco mode

As Bill says above, it just changes the throttle response and steering assistance. On a long run I couldn't detect any mpg difference between Sport and Auto modes (it wasn't called Eco on mine). I did find, though, that the throttle was a bit too sensitive in Sport, and the steering a bit heavy. Conversely, Auto gave a very lacklustre throttle response. When you switch to Auto mode (or "mood" as Fiat call it) the display shows the engine is in Eco.
Then someone on the forum pointed out that in "All Weather" mode the engine is set to full power but the steering is Normal. I tried this and found both the throttle response and steering to my liking, so left it there. Overall mpg is no different to driving around in Auto.

Re: Sport mode v eco mode

That sounds very positive but youíve reminded me the steering went really heavy compared to normal mode anyway. Might have to try it for a while. Thanks all.

Re: Sport mode v eco mode

Have mentioned before but SPORT mode makes a surprising performance difference on the 1.6 MJ - goes very well..............

I think I've already answered a similar question somewhere on these boards, so I'll repeat myself here: In Sports mode you see a lot of 3000+ RPM action, so it's bound to give you some MPG difference, especially with higher displacement engines. Can't be sure about the 1.4, but my 2.4 definitely consumes significantly more fuel in Sports mode.

Re: Sport mode v eco mode

The car revs a lot easier and quicker with with Sport Mode so will probably use a little more, as others have said it drives like a dog in eco mode especially on motorways, I've stopped using it unless there's heavy rain or snow, even then all it does is dumb down the power,

Re: Sport mode v eco mode

Gonna switch it back on tomorrow and see if I can put up with the heavier steering.

Re: Sport mode v eco mode

It was the heavier steering that spoilt Sport mode for me. I think I could have adjusted to the sensitive throttle. I ended up leaving mine in All Weather mode, which retained the lighter steering and made the throttle more responsive than Auto, but not as hyper as Sport. Give it a try.

Re: Sport mode v eco mode

I can only comment on 1.4 MultiAir engines but this is my view/practice (this has been discussed before)

1) Auto mode is OK around town, etc. where engine workload is relatively low
2) On motorways at higher speeds where wind loading/drag, and moving vehicle weight up even modest inclines and 60/70mph requires power delivery then in AUTO mode I/others have found that before you really know it you are losing speed and having to drop a gear and even then in my experience this is an exponential and quick loss of momentum
3) I generally stick to sport mode and learn that you have to have a "feather foot". When I do switch back to Auto I have no real throttle/clutch control issues BUT WHEN I THEN switch back to Sport Mode it takes a few minutes/gear changes/starts/stops to revert to "feather" foot mode.
4) With 3 in mind I prefer to stick to Sport Mode. I do have a question/issue with sport mode with regards to stability/skid/etc control functions. I need to raise these again in another thread.
5) I've found no real difference in MPG between Sport and Auto mode if you drive to the same performance regime. (regime = velocity, acceleration, average speed, demands etc.

Re: Sport mode v eco mode

For a manual there should be no difference in fuel consumption for sport vs eco as the gearing is driver specified.

For an auto mpg will increase. I have a 2.0Mjd 9sp auto and all it seems to do is hold a lower gear in sport mode. A lower gear means higher revs and increased mpg.

Also for the 4wd variants this is engaged fully in sport mode which will cause higher fuel usage.

Digressing, a few months ago on here I was reading an air-con thread, and low and behold I tried mine one day soon afterwards and it didn't work at all. I'm taking it in tomorrow where they are replacing the AC compressor.

Sport mode v eco mode

All weather mode as you call it in mine is like driving through treacle. I would call it snow mode. Low power, high traction. Not for general driving. I donít like the stiffer steering in sport so itís gone back to normal mode which is a bit annoying.

Re: Sport mode v eco mode

Well the original Sport v Auto (eco) mode question focussed on fuel consumption which I think has no sort of been answered as no/little different if you drive to the same performance profile.

What I would like a real answer to is the safety features of ASR/ESR/stability control intervention in the Sport and Auto modes.

In Auto mode on wet roads I can get the safety/stability features to kick in by being brutal/aggressive. Now this is good IMHO.

However in Sport mode on wet roads I have failed to get any of these features to kick in. Only ABS braking operation I have managed to trigger. Now I have to qualify my attempts at getting these features to kick in on wet public roads. I've many thousands of miles of hard track driving in both dry and wet conditions so I can say that I'm fairly/very well experienced at putting vehicles on the limit. So in my wet (empty) public road tests in Sport mode I was at what I judged to be a safe but still aggressive mode and I could not get the safety/stability features to kick in.

Now in Sport mode I'm told they are still operational but set at a much higher trigger threshold. Well if this is the case then I could have easily trashed my 500X in trying to get them to kick in. This was in the wet! Hate to think what would be required in dry conditions.

I don't do track/sprinting any more so have no access to motor circuits to safely test the thresholds in Sport mode.

So for me as I almost always drive in Sport mode and carefully I would like the reassurance that should I get something wrong or hit diesel/oil on the road etc. then safety stability and control features will kick in. In clearly very wet/adverse conditions I do drop out of Sport mode into Auto.

So for those of you who drive in Sport mode (especially if you are a track driver) have you ever had the features kick in?
