Hi I was just wondering has anyone experimented with fuel consumption in eco,normal and in sport. Would be interested to hear from anyone who has rough figures and would love to know how much difference beweet sport and eco especially. Only owned my 63 plate for a week and mostly drove in eco with the odd blast in sport and my first top up came in at 48.7mpg. 

It rather depends upon which engine you actually have. With the 1.6 TD I would leave Eco well alone, I tested all three settings when I got my car and Eco was dreadful, it blunts the throttle response so much that you would probably waste more fuel than Normal setting just trying to drive the car normally. I've left mine on Sport most of the time and it still usually gets more than 50mpg, all that it seems to do is sharpen the throttle response slightly, other than that I don't drive it any differently. Probably less of a difference with a higher powered engine such as the 2.0 TD or the 1.4 petrol but assuming you don't drive everywhere with your foot flat to the floor, I can't see any of these settings making any great difference to your cars fuel consumption.

I don't think it really matters which engine you have, the modes only alter particular characteristics of specific areas of the car. The engine still makes the same power etc. regardless of mode. The biggest change to fuel economy in my opinion, is if you have DSG. With DSG the Eco and Sport modes drastically change the behaviour of the gearbox and when it shifts up/down/coasts etc. This is where the most variation in fuel economy will be.

 

Eco reduces the aircon so it consumes less energy, it also dulls the throttle response and disables the adaptive element of the Xenons if fitted. Sport sharpens the throttle response and adds weight to the steering. The AFS adaptive Xenons move more too and if you have the Sound Generator it's more pronounced. Normal is well, normal and somewhere in between Eco and Sport for most of the above. None of these really makes a major difference to fuel economy from what I've seen.

 

Thanks mine is a 2.0 tdi vrs. Time to drive in sport mode for a while and do some experimenting.

Spelling mistake

You don't say whether you have a manual or DSG transmission.

If manual, then I would not expect much difference in economy because modes only adjust throttle response (cosmetic).

If DSG then there is a much greater difference as the rpm change points are altered and Eco mode also offers 'freewheeling' which can be of benefit but only in fairly specific circumstances.

 

By the way the vehicle in your profile needs an update, and welcome to the Octavia section

 fuel economy....

 

vRS TDI manual I don'ttdon'tthink yyou'll see a lot of difference in mpg and the little you do see will be worth the fun

As Ahenners says it wont make any difference unless you change your driving style.

From an engine perspective, Eco, Normal & Sport just adjusts the Accelerator pedal mapping. (sport more agressive pedal, eco lighter throttle response).

However, in the end in each setting the maximum torque & power are available from the engine just at different positions.

 

Its just a tool to encourage you to drive more conservatively or spirited rather than something which changes the engine characteristics.

 

In the end, the driver themselves makes a much bigger difference to fuel economy than any settings.

Thanks my car is a manual.

I second the opinion that you will have a far bigger influence than the settings. I also have a manual and generally leave the steering in sport for extra weight and the air con in eco to get any fuel saving that might be available, then leave the 'engine' (or 'throttle' as it should be labelled) at normal and implement eco and sport modes with my right boot!

I received my 1.4 TSI in early December 2016. Since then, each tank full of fuel, I have switched mode to see if there is any difference.

 

On my commute, with an average speed of 17mph, I was getting between 300 and 350 miles to a tank depending on the mode.

Surely there are a number of external factors outside of your control which could have also influenced the differences i.e. Traffic Conditions, getting lucky with the lights, temperature, wind speed/direction. etc. It's hard to set up a controlled test where you can directly compare the differences between the modes alone.

I reckoned a 5% saving using eco over drive, but I micromanage DSG coasting, either in, or out of gear depending on situation.

 

Sport is too revvy for me.

 

I really wish I could do Eco-Drive via the gearstick rather then eco-sport.

I have mainly used normal but switch to eco where I know there are good coasting spots (1.6tdi dsg) also use eco when climbing steep hills here in mid Wales,  If I use normal or sport I find it holds on the the gears far to much why climbing steep hills. Only tried sport once why trying to test performance but found it held onto the gears to long for a diesel and feel it accelerates better in normal. I am on my 4th tank of fuel and this time leaving it in eco to see if it does make any difference. So far I have been getting around 525 miles using 90% normal mode 10% eco. I will report back how many miles I get running a full tank in permanent eco.

As mine's a manual, it doesn't seem to make any difference with the mpg. I get around 28-30mpg regardless, with about 300 miles a tank! It drives better in sport so that's what it stays in permanently now (especially as it's petrol!) :-)

I haven't taken mine out of sport after being in and out with Sport/Eco for the first month or so. As above, I don't think it makes a massive difference to MPG - mostly how heavy your right foot is. Didn't like the tempered throttle response on Eco, so left it in sport. I've also (ashamedly as a petrol head) started to like the fake engine noise too!!

I'm playing around with the different driving modes too.

When I picked up the car, it was left in Eco mode. I leave it in normal at the moment, but I do like the throttle response & the fake engine noise when in Sport!

Personally I think driving in Eco saves you pennies, driving in sport costs you shillings. I didn't buy my 230 to save pennies or shillings I bought it to spend pounds..........

 

But theres not a great deal of savings to be honest, i bought it for fun..........

 

Always in sport............

Sppeling

I have a dsg scout and I just leave it in eco most of the time and I average low 40's with the cold weather. It still drops gears if you floor it to overtake in eco but it's just not as quick as in sport mode. I usually knock it into sport to overtake anyway and then back to eco once I'm past. Never really use normal/manual mode unless it's icy and I need the engine braking. Paddles would have been nice on the scout for that though. 

I notice no difference. I actually use normal a lot as hate the artificial noise simulation. 

I found in Sport mode I get full power easily (as you expect). In Eco mode however the engine power is limited unless you fully depress the throttle past a click (like a kick down) and you get full power. This was the same mechanics as overriding the speed limiter in my Fabia.

After trying a full tank in permanent eco mode I got 490 miles, have been getting 530 miles in normal mode, so for me I will be sticking with normal mode for 90% of my journeys and just use eco on long coasting roads.

Got a 230 dsg and nearly always drive it in normal mode.. tried sports mode and found it was in 5th gear at 80 so gave up on sports!! Get between 28 and 35 mpg.. for those who are non the wiser the 230 is petrol!!! Only put it in eco mode when in slow traffic and I remember to change!!

You can have the DSG box in D still in sport mode, just flick the stick back for the D/S toggle. I sometimes put mine in sport for the better throttle response and sound, but hate the Sport mode of the DSG box.

I'm skeptical that this is a real finding and not an artifact.

It's not going to be statistically significant result after a single tank with so many other variables...

I've recently found that on my commute in my 230 eco mode makes absolutely no difference.

 

Been trying out it for a few weeks, and although there are loads of variables ie average speed, traffic density, throttle position, blah blah blah, my overall mpg week on week hardly changes whether I'm in normal / sport (DSG in D) or eco.
