Bloody gold mate
It goes to show how much NVH is from gear train and tyres in shed class land rovers eh
Have you even got (want to know) a number all in minus labour plus hours consumed!!!

Would you do it again?

Do old series LR make good donors for ev?

Would you think their would be benefit in yanking the gear train
And then running motor to a simple small gear box straight out to rear diff
Losing complexity of 4wd if you wanting a “town car series ev”

and in Low Range , another one coming from a handheld camera when it finally uploads.

Yes I would do it again, for sure . Yes its still bloody noisy !!

Series Landy makes a great donor because the batteries can be fitted without hacking great holes in the floor or otherwise taking up load space. Better than any other vehicle I can think of , And weight distribution is not upset.

I reckon a Defender would be great to convert too, for the same reason.

Even taking off in 4th its probably still faster than going through the gears with the petrol motor, Def dont need the overdrive though. It would certainly be quieter and more efficient without gearbox, but Id suggest a gruntier motor, or even a DC Motor if you dont need regen braking.

I'm also curious as to how well it works up and down steep inclines.
Theoretically the low down(Instant) torque of an electric motor should make uphill a cinch! .. and low range downhill much better than any combustion engine'd vehicle(diesel or not).

Also would higher gearing help with electrical consumption too ... have you done the math/calculations to try to improve speed/economy balance?

Looks great! The drivetrain noise is amazingly loud! Has the cabin noise changed do you think? Heat in the cab would be much better I would of thought.

It seems to me that removal of the gearbox would be the next way to gain more efficiency and less noise.

Would you agree?

Talking drivetrain
Bush - would it be possible to mount the motor to the diff nose directly turning the pinion?

I guess could run one front and rear , bringbin the front for launch!!!!!

Feasible ? Obviously would want to get tyre siZe / Diff gearing spot on
But seems a funky way to EV a series

Could yank all the midline spinny bits that way?

Yes, for an Electric Vehicle its very loud.

noise before and after , Compare both taken with the same camera .

Before = LandRover Lightweight, test drive - YouTube

After = LandRover EV Conversion, First drive part 3 - YouTube

No factory EV has a gearbox , but they typically do about 5000RPM at 100kmh , 4.7 is too high , Tesla has something like a 7:1 final drive.
