The problem for aftermarket long range tanks will be that the monocoque is so much more efficient than a body on chassis. From the overall monocoque view it looks pretty tight for space
The logical place for long Range tank will be on NON E versions using that space under the rear floor if there is space

Notice the DCDC and battery as per my last post above.

I think Steves reference was to my posting of the RR Sport PHEV schematic as we were trying to work out if the electric drive for a PHEV version of the Defender would be through the transfer case.

Thanks BR
That sums it all up pretty nicely
Seems the starter/generator also acts on takeoff to give some extra oomphf which is kinda cool.

But looking at the specs of the battery
Liths run at 3.7V so their battery back is 14 3.7V in series cells for a nominal 51V
Running at 48V

At 200Wh you won’t be using the battery for a fridge BR
Excluding losses in DC that’s like 16AH at 12V nominal

Cheers BR. From brochure above. “...while a plug-in hybrid variant means there is a new Defender for every 21st century customer.”

This is the most exciting Defender yet to be released IMO.

So how would one connect solar to this setup?

Would this be only bat in car?

I’m guessing it will be the only battery in car
From Mr Google a big Lith Jump starter (4000A model) stores 88Wh
So this battery is all that will be needed to get that 3L petty running

But it really is small capacity if you want deep discharge / fridge use etc

200Wh say 10% loss through DC DC to 12v will only give you 15Ah
Not really a system to run a fridge off

I’d say you will need a fridge battery with charge circuit either dedicated standalone solar or hooked into the 12V system

Obviously until hands are laid on the above is speculation

I’d say all the current technological movements across many industries are actually increasing inconvenience rather than improving it.

Battery tech isn’t mature enough yet, so the next 10+ years of vehicles for all-round use will be compromised.
City runabouts are ok; everyday, all purpose vehicles aren’t even remotely close.

And the infrastructure- especially in AU is far from ready or mature enough to cater for it.

We’re talking a return to the days of a roadhouse every 100 km, high current charging systems with grid linkage etc.

Currently a person can get in a conventional vehicle and drive until their bladder can’t handle it. With EVs this isn’t there yet (unless you have a weak bladder ).

If / when tech can provide more energy, charge in under 10 minutes to full range... that’s when the tech will be truly ready.

Apparently LR are saying large SUVs are not suited to BEV due to weight, efficiency ,size of bats needed etc all working against eachother.

For the new defender i believe its ICE, MHEV, PHEV & future i believe will be hydrogran fuel cell if anything more (i think thats what JLR & BMW are working on.
