MPG for those interested.

[John A]

Thanks! Useful to know that average speed and mpg of trip B do not reset.
Since I have never reset my trip B the mpg and speed should be correct data for my 38000 miles? Can't look at the moment

I have auto reset on tank fill set and it seems to reset B as well as A so I can't see my data for all 38000.

I know my Mk 3 has various options for resetting A and B and am sure that the Mk2 I had was the same. I use A to reset on refuel and B for ignition on / off.

Thanks that would be good...I will have another look. I know on my Mk2 I could have A and B different settings and when I got the Mk3 was surprised and disappointed that it was different...but maybe user error. I think we had a thread about it back then.

https://clubjazz.org/forum/index.php?topic=8210.msg40747#msg40747 is the thread. It confirms what you say that they can be set independently...I had forgotten.

Filled up yesterday and the display said 40.4 mpg. I am more than happy with that. My husband is using my Jazz this week so we will see what mpg he can get. I have his Type R today and what a brute. He told me to leave it in Comfort mode not that I will mess about with things. Not the best experience in Edinburgh morning rush hour traffic.

My husband has been using my Jazz Sport this week and filled up last night. Display said 51.1 mpg but he calculated the true figure and it was 49.7 mpg. I don't know how he does it. The display on his car which I am using is currently showing 19.5 mpg!

[Jocko]

You have a fair bit of catching up to do!

Presumably your husband has longer runs at steadier speeds, with fewer stops and starts?

It might be ungallant to say it but is your right foot a tad heavier

Or if the setting is "reset on tank fill" it might just be that it had only just been filled up. That is the only time I see very low numbers, or if Jean is looking at the current trip on the infotainment screen.

Or using the break pedal for other than actually bringing the vehicle to a halt. So many people think that there's one pedal to make the car go faster and different one to reduce the speed.

My husband does considerably more miles with most of it in lighter faster moving traffic.

I had done about 150 miles since topping up. I have now done 190 miles and it is reading 19.8 mpg. At this rate I should see it over 20 by the time I have to fill up at the weekend

I do 30 miles a day in stop start queueing traffic so it pretty much is a case of one pedal or the other.
The Type R is not a car for daily rush hour commuting to and from the city centre!

That makes it more difficult but allowing a gap to open up to the vehicle in front ought to allow you to minimise the need for brakes. A few months ago I was having to commute via J10 of the M40 which meant fifteen to twenty minutes in a queue of cars and I rarely needed the brakes. Instead of stop/start try and just inch along at the average speed.

An annual report on my Mk 3 1.3 SE CVT Jazz.

I've now had it a year (just over in fact) but I can report the following:

1) Annual Miles 2,362 (lower than normal but no UK holiday this year).
2) Daily average miles - 6.47.
3) Average speed 18 mph.
4) Lowest mpg - 33.8 (actual not computer)
5) Highest mpg - 50.1
6) 80% City Driving (equivalent to old NEDC Urban Cycle - 20% at Extra Urban)
7) Computer out by exactly 4.2 mpg - Average MPG is 42.2 - computer says 46.4

So, how does this compare with my previous Mk 2s. I have excluded my last Mk2 because it did some long journeys including a period where I was driving 75 miles a day to have radiation treatment. More typical was my first Mk2 which averaged exactly 40 mpg over very similar driving conditions. The MK3 shows a 5% improvement in mpg although I suspect it has had fewer longish trips.

I'm quite happy with these figures. A typical job for my car is a 4 mile return trip to the supermarket. I probably rarely, if ever, get to a decent operating temperature.

Hubby filled the Jazz up today before swapping back and he got an indicated 53.3 mpg and a calculated 51.8 mpg.
He thinks it a pleasant comfortable car to drive but grossly underpowered for a Sport. He says it needs a turbo or a bigger engine. 1.5 litres is not enough.
I had to fill up the Type R yesterday morning and the display said 21.4 mpg. I had to top it off again today before passing it back and the display said 18.7 mpg. Mind you it was only for 65 miles.
I am glad I do not have to put Shell V Power in mine. The price per litre is terrible.
