Am I right in thinking that the D4 does not have Stop and Start technology in it?
If so, why not?  And is it likely to get it in the future? 2007 Porsche Boxster (987) 2.7

I think the stop/start can only work on a manual at the moment.
IIRC, LR are trying to get stop/start for the auto. The next American ex-pat that calls it a "truck" is going to find out what 2.7 tons feels like on their foot...

I had it in a loan car I agree it was a PITA
if you set off too quick the engine wouldn't switch on

The concept of stop start is great until you realise that some components are having to operate thousands of times more than if they were just used in normal operations ...ie. the starter motor perhaps  21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

I think it was beefed up abit to taken into account the extra abuse

We have a BMW s/s in the family now and have only put £10 of diesel in (on top of the limited fuel provided upon purchase) - covered 600 miles so far My mate's Mini Cooper D has S/S and we got over 75mpg on a motorway jaunt darn sarf last week.
DG, I believe the components put under extra pressure have been improved?
Land Rover wrote:The more frequent stop and start activity means that demands on the starter motor are forecast to increase up to three-fold during the lifetime of the Freelander 2 TD4_e. So, to accommodate the durability demands on the vehicle's 2kW starter motor, a number of changes have been made.
The grease seals have been enhanced significantly and new hard-wearing copper-tungsten contact material has been sourced and specified across the TD4_e range to enhance wear resistance within the starter solenoid.
I'm surprised they're releasing the new 10MY range without it TBH. 2007 Porsche Boxster (987) 2.7

The starter motor is beefed up, as is the battery, etc. 06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

Appreciate that might be the case ......but if you think of a single journey across town of say 10 miles ...how many times would you stop .. 20, 30, 40, 50 times ? Thats just on one journey ....maybe I should have said 'hundreds of thousands of times' 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

But has the Stop/Start got anything to do with getting 75mpg? If you were on the motorway I would hope that the engine would never switch off to save fuel

Nearly all Discovery 4s will be sold with automatic transmission - only the 'old' 2.7s will come with the manual option.
Stop/Start systems take advantage of the delay in the following whilst the system starts the engine:
1. depressing the clutch and/or disengaging the handbrake
2. selecting 1st gear
3. applying revs
4. easing out the clutch
During this time, the car will engage the starter motor and the engine will turn over and fire up....by the time you reach number 4, the engine is working and ready.
In an automatic, the normal thing is to take the foot off the brake and immediately press the accelerator and expect the car to move.
I believe that this is the reason why Stop/Start is not available on auto vehicles at the moment - it just wouldn't be smooth enough to be useable.....but it's only a matter of time until they get it working 2006 Discovery 3 TDV6 SE Auto Buckingham Blue

They are significantly improved to take into account the duty cycle they experience  06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

So given that why cant they make these components 'significantly beefed up' for the rest of us  ...does make you wonder if components have a built in life expectancy 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

'Cos then we'd have nothing to whinge about
Parts don't have built-in life expectancies, but costs that must be acheived through the design/specification of them......
Saying that though - ISTR that the new S/S FL2s costs the same as the old ones did - so how do they recover the extra build-cost?? 2006 Discovery 3 TDV6 SE Auto Buckingham Blue
