From the MPG topic.
"I have arrived at speed, drive settings and adapted to give what I feel is the optimum driving method to suit me.

General driving locally is up to 53mpg when conditions allow in B mode and ecco, climate control always auto varying temp,  and use of any fitted auxiliary like heated seats as required.

When motorway use for distance driving, same auxiliary use but D mode ACC and ecco speed set to 70mph on dual carriageway sections where permitted.

Attached graph shows mpg after each fill and the Accumulative mpg since new.

The dips in fill mpg in all cases attributed to after motorway or distance runs when max  speed used where permitted.

I report on here my accumulative mpg in site settings  since that is the real indicator over all conditions, and since settling on settings it and fill mpg naturally increasing towards a settled figure at some point.

Stopped thinking of the multiple variations that may occur as generally I cannot influence ambient conditions, but do monitor tyre pressure."

I guess perhaps 90% of my driving is in 'B' mode, unless I need ACC, where of course I have to use 'D' mode.
Air con is always On, set to Auto 19/20c.
I have to admit that not much of my general motoring is on motorways, most roads are restricted to 40/50mph.
My style of motoring is to use 'B' mode to slow down, only using the brakes for the final stop.
Battery levels can vary between 2 bars, up to 10 bars, depending on terrain, hills etc.

The attached photo show the figures over the last 3 refuels, which I think are pretty consistent.
I'm not bothered about any difference between the recorded figures and the real world, as its only around 1 or 2 mpg and with these results, who cares!

Just out of interest, can you change from B to D while moving...?

Drivers of HEV vehicles just need to remember that, with the exception of the 'P' position, moving the gearstick does not change 'Gear' in the accepted sense. You are simply switching electronic control circuits, which control Forward/Reverse and degree of Regeneration braking.
Quite obviously you should NEVER engage 'P' whilst moving.

When I reverse off my drive, I guess there is still some reverse movement, when I change to forward, probably less than walking pace.

...I'd be slightly apprehensive of changing into Reverse nonetheless!
Maybe trying in someone else's car first would alleviate my fear  :o ;D

Just don't press the 'clutch' pedal when changing gear( b to d)..
I am doubtful that B saves any fuel c/w D. Has anyone done 1 fill with one, switch, switch back?
Or seen any tests on Toyota , Hyundai hybrids.?

When I use B, I get a mild pulsing effect, that the slowing is not constant. Whilst using X and footbreak is more smooth. Am I alone.?

YES,  'B' mode Regeneration, provides very smooth braking from any speed, down to walking speed and then requires the footbrake to bring the car to a dead stop, very much like being in a lower gear on a manual gearbox. I would suggest any 'mild pulsing effect' needs to be investigated.

No pulsing in mine.

Do you have any particular reason for not using "B"?
