So my fourth consecutive calculated mpg figure of over 60 mpg - this time 61.9 (66.7 on the car's computer) and this gives me an mpg figure for the year of 57.7. Pretty pleased with that figure to be fair.

It will start to dip again as the weather gets cold and I burn petrol to keep me warm. Quite a range over the year from a low of just over 45 mpg to a high of 63.6.

Just filled up, which reset my trip, then drove off up a fairly steep hill.  12 litres per 100km. ( 23.5 mpg ! )  :o
(I am in foreign parts at the moment.  The constant fuel consumption 'bar' makes much more sense in metric) 

Of course it soon settled to something much more pleasing.   ;D

Latest fill update - overall mpg still edging up - now 54.66, increase 'held' back by required motorway running

Picked up my new Jazz EX Style on Tuesday and today was my first proper drive. Mostly dual carriageway and motorway, around 80 miles round trip with speeds mostly in the 60-65mph range topping out at 70mph. My average was 56mpg, I was hoping for 60+, so maybe it will improve a bit when the engine gets a few miles on it.
For reference my 2022 Volvo XC90 B5D usually averages around 45-46mpg on the same journey.
Overall, it drove well, was quiet and comfortable, stereo sucks compared to the stereo in the Honda e I had before and none of the range anxiety of the e.

My average was 56mpg, I was hoping for 60+, so maybe it will improve a bit when the engine gets a few miles on it.

Its  fuel advantage over other cars at motorways speeds is welcome  but not as impressive as it can be in town and slower speeds. You really notice the fuel penalty for even a small increase in speed. (and  saving for a small reduction in speed and a gentle right foot)  But even at 70 mph you may improve on 56 mpg . Colder weather (a feature for the next few months  >:()  ) does increase fuel consumption. It does with normal cars, but maybe not as noticeable due to the consumption displays., Fuel consumption in warmer weather is what  really brings a smile to your face.  :D

 It can also vary quite significantly depending on whether  there is a head wind  or tail wind  or the route is predominantly up hill or downhill. You may have been unlucky with the overall average on that particular  journey    I sometimes  wonder why the car seems to be guzzling fuel for a while when the motorway or other road seems flat to me  yet with no obvious change to topography, speed  or battery level it might use no fuel at all.  Best to give it more  time to average  out.

Some find adapting their driving slightly to the cars strengths can help.    Easing back slightly, rather than going for every last bit of available power can reduce fuel consumption (and noise) significantly without noticeable loss of performance.

My daughter and family live in Cornwall. I live near Coventry. That's 275 miles each way. I am able to use ACC almost all of the journey. Out of holiday season I can do the trip in 4 hours. I am not willing to drive slower than the maximum allowed speeds, (plus 2 to compensate for inaccurate speedo) ;  getting there in the shortest possible time trumps economy.

It was a windy day with some significant changes in elevation.
I just did a quick 2-3 mile each way, in and out of town trip from a cold start and achieved 56mpg, so that's pretty good, a journey that was always so inefficient in the Honda E, so clearly the Jazz is happier at town rather than motorway speeds.
I feel I am almost an expert of squeezing efficiency out of my vehicles, my previous BMW's 540i touring and X3 M40i, both up to 43mpg on runs, regularly in the 38/39mpg range and 50mpg on my current Volvo XC90.

The Jazz now sits nicely as our second car for short trips around town, whilst the longer journeys are catered for by the effortless comfort of the XC90(provided the end parking spot is big enough)
The Jazz is a much better overlap to the XC90 than the E having both a range and space advantage.

I started out at 56mpg from new with just shortish trips, but as I did a longer trip or two it got past 60mpg and still around 59 now going up on longer trips. But the colder weather and warm air con will knock a few mpg off, the engine seems to be on more the last couple of days.
