Honda Jazz Mk1 2002-2008 / Re: What MPG are you getting from your Mk1 Honda Jazz ?

I watched the video. Seemingly the car was bog standard with no special help from Honda. The dealer supplied the car and the AA drove the escort vehicle. Following behind the van would certainly help.
For those that ask how far you get after the display shows zero miles left, their car showed zero with 60 miles still to go!

But the Jazz that went from Lands end to john O'Groats on one tank of fuel was a manual gearbox,  just goes to show that in proper hands the manual box can outperform the CVT in the MPG area.
With someone from the Honda factory on board who would have had access to the detailed performance data and thus knew the optimum engine / gearbox settings to get the best economy. They must have worked out beforehand that they stood a reasonable chance of succeeding. If we had access to thie same information then we wouldn't need to be discussing the optimum driving style for getting best mpg.

The team stayed below 40mph, maybe some of the people I follow are hypermilers, trouble is they do 40 in 60, 50, 40, 30 and often 20 limits, so maybe 40 is the optimum speed....

If, as reported, being blinded by the sun was a possible contributary factor then I know that my eyes (somewhat younger than DoE) can't handle rapidly changing lighting conditions as well as they used to. Perhaps this aspect should be part of the eyesight test. Ability to read a number plate doesn't mean everything is OK.

Thanks All

I have emailed the dealer and they replied that I should show it to my nearest dealer.

I have booked an appointment for same.

I will update the diagnosis and solution if they provide some fix.

Thanks Again!

Wow!

Yes - I've seen some pretty bonkers stuff on hypermiling forums. That car above, especially the back end, looks like my Dad's old Standard Vanguard. A Jazz/Vanguard hybrid.

I bet the hypermilers prefer a manual box as well,  as it absorbs least power than other options.
A true hypermiler would always choose a manual, not just from the power absorption but the fact that they are in control of everything it does. Mind you, some of the things they do are so extreme for fractions of a mpg. Things like moulding body parts, taping off panel joints and door openings and flushing wheels, wheel apertures, and even complete under-bodies!

Honda's recent vehicles with CVT transmission achieve better test mpg than the manual gearbox versions.

But the Jazz that went from Lands end to john O'Groats on one tank of fuel was a manual gearbox,  just goes to show that in proper hands the manual box can outperform the CVT in the MPG area.

Maybe by using an economy electronic map for CVT the revs can be kept low as possible even though the accelerator is being pressed hard,  but in sport mode the car behaves more like a spirited driver with a manual box so MPG suffers.  So with a human in charge using experience and anticipation ( and all the other stuff humans can do that computers cannot ) the manual box still outperforms the CVT.

I bet the hypermilers prefer a manual box as well,  as it absorbs least power than other options.

Without even beginning to understand the science - this actually makes sense. The CVT probably does edge it with a "normal" person behind the wheel but the manual affords more scope for the experienced hypermiler.

I f you have concerns just let the supplying dealership know in writing, use signed for postage as proof & then give then an opportunity to put it right to your satisfaction, Buying from a dealership you have 30 days -  6 months in which to raise your issue.
