Fuel Consumption

[Jazzik]

What is your average fuel consumption?

I don't really like mine: 5,3 l (44,38 mpg).

Stani, to start with, you are converting l/100 km to US gallons per mile. That's not done when you use a UK website! Better use Imp. gallon (UK). https://www.thecalculatorsite.com/conversions/fuelconsumption.php

Econ is only useful when you like to grow greenery on your dash screen:

I only drive in "D" when I want to use cruise control, otherwise always in "B". Just try and choose what suits you best.

As for consumption: give it some time, enjoy your new car and you will see that your Jazz is really economical. I keep track of my consumption on Spritmonitor: https://www.spritmonitor.de/ , visible here at the left.

I have a 72 SR, had it from new so just over 2.5 years or so.
Mostly used for commuting to work (now 3x a week, was 5) - 10 miles each way. Plus 2 or 3 short 1-2 mile trips around town per week.
Longest drive it's ever done is ...err....about 35 miles.

Tank to tank average mpg never lower than 66, higher in summer to 72/73.

Experimented with ECON when first had car for a few months, but couldn't see any improvement, so never use it now. Reckon I'm quite light footed.
Rarely use heat.
Drive with a mix of B and D. Rarely get to high speeds - average speed on journey to work is usually under 30mph, with a 30sec burst on the dual carriageway to around 60-70mph!

My 72 EX is now getting up to the 70 mpg mark again, now that the heater is no longer needed.
Even having the A/C on every now and then doesn't seem to affect the mpg in the same way the heater did.

62.0 mpg over 56,300 miles 71plate SR

Lincolnshire Rambler: what are the values ​​"0.6" and "9.9"?

[Lincolnshire Rambler]

That was when the car was new , think it was during the 1hour handover in dealer as the car controls explaned  . In tbat hour the petrol engine started up a coupke of times giving 9 mpg over 0.6 miles before i reset the A mode to 0 miles just round the corner from the garage . The A mode has never been reset since so the 56332. +0.6 miles is the distance travelled since new!

[Jazzik]

I keep track of my consumption on Spritmonitor and it turns out that our Jazz is a bit optimistic about fuel consumption. The real consumption appears to be on average about 4 to 4½% higher than our cars want us to believe.
Taking that deviation into account, 62 mpg on screen means an actual measured average consumption of about 59.5 mpg.
Not bad!

[Lincolnshire Rambler]

Yes even 59 mpg is good over 56,000+ miles as its across 3 winters and every road type encountered . I often plant foot to floor to enjoy the jazz zooming away from traffic lights or roundabouts so i dont drive with economy in mind all time by any means !😁😁😁

Surely this topic covered comprehensively elsewhere - under MPG For Those Interested.

[Marmoset]

I've done over 30,000 miles and for the last 25,000 or so miles, I've averaged 72mpg.

I drive mostly in B mode, aiming to get as much of the regenerative charge into the battery, so that the ICE engine doesn't have to do all the work. 

"B" both outside the city and on the highway?

Yes, nearly all the time.  It hasn't broken the car yet!

[Kremmen]

I've never used D, far prefer the one pedal driving in B

and that's after driving auto's since about 1972 when it was D mode all the time so I'm used to both

[ninanina]

Strange because I never use B mode

If I’m going down a very steep hill then that would be the one and only time I’d click into B to give more engine braking.  It happens very rarely

I was the same when I owned my last two Prius and only used B for steep descents

[stani]

The Honda dealer told me: city "B" outside city "D". You can't put cruise control on "B".

[Kremmen]

You can't put cruise control on "B".

Another reason to use B, I tried ACC a few times early on and had issues with it thinking vehicles in adjacent lanes were in front so slowing me down

[ninanina]

Never had any issues when using the smart cruise control;  ACC

The car seemed to lock onto the car in front and modulate the speed accordingly; it had no drastic braking or acceleration just a smooth transition

The few times I’ve used ACC it was perfect and so relaxing
