Canadian "mileage" (l/100km) and 99.9l/100km reading

Ironically, if I do it alone, I can barely get it to 5.1 - as if the added weight has no impact, since I'm not doing Stop & Go.

Winter to too variant - too many factors like temperature and road conditions.

Summer - dry pavement on the highway versus raining / hard rain, can impact by as much as .5L/100 extra !

USE the Cruise Control - ALL the time ! I was always getting 5.6l/100KM, with the cruise control, it dropped to 5.2 for the same speed / conditions (doing a Reset in between trips).

Even at 100 km/h I would have thought that < 5.0 would be possible in the summer. If you go 90 km/h you might be able to get 4.5 or just under. Also, I find cruise control to be too aggressive on inclines. I let my speed drop a lot during a hill climb, combined with speeding before the hill.

Indeed. 100km/h will next you < 5L/100km (Mark, did you check your tyre pressures?)


Whether I have 4 people + luggage or just two, it seems fairly consistent at 70mph as I get 5.1L/100km at that speed.

When I have cruise control on I assist it a little by allowing my speed to gradually increase by applying pressure to the accelerator before a hill then let it come down slowly by maintaining that throttle position as I go up the hill. The ideal is to be back on cruise just as I crest the rise.

Example on my way home is a railway overpass, that is the road goes up over the rail line. I have my cruise set at 60km/h, the speed limit, two to three hundred metres I apply slight throttle to bring speed to 67 to 68km/h by the time I star to climb, I hold the throttle steady as I go up the hill and try to time hitting 60 for the peak of the overpass then allow the car to coast down the other side again trying to glide just over the speed limit. The car is then allowed to glide with slight throttle(glide) until the cruise picks up the throttle again. I think this helps, it seams to.

Just out of interest to us non-metric Prius drivers. When you're showing l/100 km you are really talking fuel consumption measured in liters per 100 km, the inverse of "mileage", measured in MPG, which we get indicated on our Prius' here in the US. (it's called the Consumption screen, but it is really the Mileage screen)

So when the ICE is not running, but you are moving under electric power what does the yellow bar on the right of the Consumption screen show? Zero I assume, since you are burning no fuel. As opposed to the reading in a US Prius' of 99.9 MPG (since infinity cannot be displayed).

Do the 5 minute bars each show average l/100 km for that segment?

Yes the instantaneous consumption bar shows zero when the ICE is off and yes the 5 minute bars are in L/100 km. So the lower the bar the better the mileage. The scale is 10 is highest, 5 in the middle and zero at the bottom.

bah... in all this snow, i'm getting 6.4L/100km (granted some of that was having fun in the snow so prior to that, it was showing 6.1L/100km).


anyway, is anyone's bladder significantly shrunken?? The light came on and I only pumped 28 litres (around -6c at that time). It can't possibly shrink that much. What about those who are living in -40 degree weather?

I recently put in 27-28 liters and it had 2-3 blips left. Looks ok.

It hasn't gotten above -20C here for the last week. I do mostly short trips, so the ICE is running almost all the time. Fuel consumption (indicated on the MFD) at the last fill up was 7.9 L/100km (roughly 30 mpg [US]). With two bars showing on the "guess" gauge, the pump clicked off at 24.2 L (tank capacity theoretically is 45 L). That gives some indication of the bladder shrinkage.

After driving 45 km on the current tank, the gauge now shows 8 bars, and my consumption is about 8.2 L/100 km.

FWIW, I owned a 2004 Echo Hatchback before the Prius. Under similar driving conditions, the Echo's fuel consumption was no better than (and sometimes worse than) what I'm getting with the Prius, so I'm not complaining.

ok good to know. Pumped 22 litres today with 2 bars left. Ugh, all that wheel spinning is draining the battery and increasing the fuel consumption.

Yeah and plowing through snow is probably like running in water.... increased resistance.
