Weights and mileages

One of the most common questions I am asked about the CARDIS is what mileage1 I get from the Iveco. Before answering that one directly, let’s consider a couple of related matters.

Driving practices

When towing on highways/good roads, I habitually set the cruise control at about an indicated 94-95 km/hr, which translates to about 91 or so km/hr true according to the GPS app I use for checking these things. Where road conditions are not conducive to this speed (e.g. lower limit posted, poor road surface), then I reduce speed accordingly. This latter circumstance has however, been definitely a minority of the time.

When not towing, I normally would cruise at or about the posted limit where reasonable.

Weights

The Iveco tares at 2760 kg, with a GVM of 4495 kg.

Weight in general travel configuration is about 3300 kg.

The CARDIS tares at 3740 kg, with a GVM of 4500 kg.

Weight in general travel configuration is about that (4500 kg) or perhaps a shade over2; although we’re working to bring that back to about 4300 or 4400 kg.

Combined weight in general travel configuration is therefore about 7800 kg, just a little under the legal maximum of 8000 kg.

Mileages

I’ve been recording fuel used since we bought the Iveco, and that currently stands at:

  • Total distance: 33900 kms
  • Total fuel: 4522 litres
  • Overall consumption: 13.34  l/100km3
  • Overall average fuel cost: $1.88 /litre

All well and good, but most of that 34-odd thousand kms was not towing, and towing the CARDIS is the scenario of most interest. That one is a little harder to nail down, but from a recent loop around NSW—Granville, Jerilderie, Bourke, Granville—of some 4100 kms or so, with about 2500 of that towing the CARDIS, we’ve seen an overall average of 16.3 l/100km4—see the two images below from the day we finished the loop. Specific checks on a couple of the legs gave just under 18 l/100km5, although I didn’t actually write this down anywhere 🙁 .

Footnotes:

  1. Technically I guess this ought to be “kilometreage”, but that sounds totally wrong!
  2. Actually quite a bit over when we finally got to weigh, but we’ve taken URGENT action on that
  3. That’s 21.2 mpg for those of you still locked into the old money
  4. 17.3 mpg
  5. 15.7 mpg
