Eco mode

Recently purchased interstate and transported from MEL to SYD playing with Eco. I found that I was able to get down to 7.1 L/100, but once I topped up the tank I struggled to keep it under 8.0 L/100, both in Eco and D mode while at 110 on the Hume. This is with the 162 Allspace so I think the weight of the vehicle and a full tank might have something to do with it.

I suspect it has more to do with the speed and wind resistance as they are aerodynamically efficient

I used to do a regular run of nearly 200 k on the Hume from Melbourne to Nagambie and always used 0.2 to 0.3 L/100 more going to nagambie and this is because of the change in elevation I suspect as there are more uphills than downhills.

But more noticeable was that if I sat on the speed limit of 110 compared to sometimes taking a more relaxed drive at say 100 there was a 1 to 1.5 l/100 difference.

For a while they had extensive road wire rope works and at 80 reduced speed for a considerable length saw the economy improve by a further 1 l/100 or so.

Wind resistance increases by a factor of 4 compared to speed .

Great thought. Agreed there was a slight uphill drive out of Melbourne.

While it was pretty flat from Melb to Gundagai the rolling hills of the southern highlands would have had an effect - this is about the point I saw the increase in full economy.
