I’ve had my 2021 Jazz for just 24 hours and am very pleased with it but, the mpg being quoted on the dash is only 37.3 which isn’t as good as the 2019 Civic 1 litre I traded in. Despite its age it has only 915 miles on the clock so it must have sat in the drive of the disabled previous owner for long periods of time. I’m a complete novice to hybrid driving so any guidance would be very helpful.
So is there a golden rule for achieving decent mpg and what are the best settings on the car for doing so?
I fit the apparent demographic for the Jazz being 85 but thankfully quite fit. The heated steering wheel was a seller for me.
It may be because the dealer recently reset the trip meter to zero or it reset itself when they ,or you, put some petrol in the car. If shortly after this reset the car is held up in traffic with the engine running , but not moving very far, or you sit in the car learning its 'clever tricks, or its in a workshop being serviced, the computer will register quite a lot of petrol being used by the engine but very little distance covered. This will be converted to a very bad, and misleading , MPG figure.
To illustrate this you may have noticed the little row of green eco performance trees displayed . Its the computers assessment of how economically you drove on that trip.
In normal driving I get lots of green leaves. But if I start the car briefly to move it on the drive or check something on the display etc I get bare trees. The computer is most unimpressed with how much gas I guzzled on that 'trip'.
If you swop the trip meter between A and B you may see a different, more typical MPG displayed. But even this one may not be great if, as the mileage suggests, the previous owner only did short journeys.As Kremmen says short distances with the engine cold will see MPG at its worst.
When I took delivery of my brand new car with very few miles on the clock( ,and those mostly stop/ start on and off the ship , into the dealers yard ,pre delivery inspection etc ) , the mpg displayed was similar to yours. It remained a terrible average for the first 50 miles or so when it rapidly improved to my more typical 66 mpg.
Main advice for good mpg is drive it with a gentle throttle. Try to get a 'feel' for when the car is happy. Sometimes just easing back on the throttle a little brings good improvement in mpg with little loss in speed.
Some find using Econ mode helps by stifling throttle response a bit. Some prefer using B mode rather than D mode But check out then pros and cons of each on this site and see how you get on.
Heated steering is great. Heated seats even better.. Using these for the first few miles on a cold engine instead of cabin heating improves mpg.
