MPG for those interested

[aphybrid]

New (Jan 2026) Jade Green Crosstar mpg - showing accumulative increase overall at the moment (57.56mpg) from 2021 model - 53.95mpg.

Have always had Eco mode selected and in this car been using mor B  drive.

My 2026 Elegance in the first tank gave me like 4.73L/100KM.  (33.54L and 709.4KM). I think car total trip was like 4.5L/100KM. But this could also vary depending on how far they filled the fuel the gas station employees.

This is for extra-urbane usage, and mainly I do every day 2 trips to kindergarten where i hit like 60 speed bumps (15 per way) one way is more uphill, the return way is mixed plain/downhill.
As a reference my 2014 Diesel Outlander consumes like 7.6L/100KM with this usage.

Overall I'm really happy with the Jazz fuel consumption.

Updated chart with latest fill'

Accumulative MPG now 56.15.

Of interest this fill car figure was 63.1, calculated from actual fill gave 62.87, so not very much optimiism!

I just drove twice round the block by the petrol station in search of a 1000km tank. Close run thing!

I do appreciate your zeal of reporting your car's performance!
However, to make your reportings truly valuable you probably should also regularly share driving conditions, average speed, tyres used, reported average by the fibometer etc.

As your accumulative MPG is in the mid fifties, I'm assuming (yes, I do know about the pun: ass u and me) that you normally are doing only shorter trips (and even those under "harsh conditions") or are mostly on motorways at speeds well above the limit!

My (limited - 26+ thousand miles) experience is, that the Jazz truly excels at lower speed levels and motorway-speeds are its ultimate nemesis!  (anything above about 90 km/h - about 56 mph) will truly bite into your fuel efficency!

I'm keeping a detailed record at spritmonitor (and yes: I do get nervous whenever the fuel gauge drops near to half)

Living in hilly eastern Switzerland I'm quite "comfortable" with an average of 70 mpg

Latest fill updated to mpg chart.
Tried to include xlsxls chart where calcs done but this not alllowed, took a screenshot which you may be able to expand and view.
Majority of motoring is rural roads with target speed 50mph.
mpg increasing, car 'loosening' up??

Best driving car I have had which includes many Hondas.

Improvement could be due to warmer weather. A full year is needed to get a meaningful average.

Previous Crosstar over  4years approximately only got above 60mpg 4 times, and overall mpg in that time 54.02.
Not so much time in B mode with that car.

I've just sold my 2025 Mk 4 Advance to the dealer and the fibometer claimed a lifetime average of 73.6 mpg (with very little winter mileage). My own records of fuel into tank show a more modest 71.1mpg indicating 3.5% optimism by the fibometer.

That’s a very good result, partly showing what a difference seasonal weather makes. What was the total mileage?

That was the mileage since new - just over 7k.
