Thread: iGO and car engine type routes? (Diesel)

And how do you expect the type of fuel to affect the route?
Every fuel station have all types of fossil fuels

Diesel routes don't exist, that's Google's nonsense

Diesel routes does works in Google maps algorithm. I have tested it personally in the UK. I don't know how good or bad this algorithm works currently for other countries. This is something new in it.

On exactly same trip between point A and B I went several times, when started using google diesel method I noticed slightly better fuel economy and as well slightly different route. Fuel was taken always from the same fuel station.


If you use petrol and diesel cars, then diesel is more eco on motorways rather than petrol, while petrol is always more economical in cities when a lot stop&go rather than diesel. That's the key factor for diesel routes, I think. Definitely it was putting me on slightly different routes.

It does work for me, that's why I started to looking for map solution (hnr file) for iGO if exist. I can see short/fast/eco routes hnr, I hope it's just matter of time and it will be introduced hnr map file like Diesel, EV, petrol.

There is not much to do in maps apart of map route updates so I think that companies are looking for the way to make their product more attractive. A lot new options that's rubbish but this diesel thing is really working for me.

It's not that simple.
For example:
Why better economy if you have a longer journey? Apart from fuel, tires, brakes and other moving parts wear out more. And then what did you save? What about the other expenses? Time?
There can never be absolutely the same road conditions between two points even on same road ...

There are economy routes in iGO (also, actually calculation - green), and again it is an approximate algorithm. How accurate it is ... who really knows

Recently I have done about 7000km within 12days, tires and breaks looks good, all moving parts as well good (I do repairs on my own), only difference is my spending pocket which is in better condition :-D

Accuracy can be done only if driving between A and B daily. I have tested this way algorithm before my long journey.

Why better economy if I have longer journey?
Yes it doesn't make sense, but if we take in to consideration topographic map then it does make sense if you for example per 500km do 50km extra but with 50% of driving on flat rather than hills then it makes huge difference. Weather in maps: if map will take in to consideration average wind and add it up to calculations that's another option to make it even more eco.

Time? I prefer save on fuel rather than go extra hour to work :-D

Eco routes in iGO? Yeah I have tried it, it seems to work same way like eco routes in Google maps, but "engine type" eco routes in Google that's definitely something different according to how it puts me on route.

If you drive a truck, makes sense. There are separate files (ftr) and special settings in iGO for that, combined with hnr files give what is needed

Brakes, tires and bearings look good, of course, but they wear out more. That cannot be "seen" on such a short road sample, not even on more of them

By all means, use what you think suits you better

Well, the trucks, buses etc are (almost) all with diesel engines, aren't they
You have to use ftr files with hnr

Otherwise, why would a route be more suitable only for diesel, the same is saved with other fuels or even EVs
Economy has the same meaning for everyone

Boki, last days I was playing with it.
I have updated maps in iGO (2020--->2022)
Now, as Q4.2022 when I pick TeleAtlas and method for planning: Green then basically it's the same thing as Google Maps. The differences now are very very small.
So, conclusions:
Google introduced their new features in 2021/22 for few countries. TeleAtlas 2022 Maps works now very close to, while 2020 maps not.
So I do believe new hnr does the same or very similar job and this is not any magic google algo but maps, for which you need software: for example google or iGO to drive these features.

HERE maps not tested yet.
