Thread: EV general discussion

I do like the effort they put into it, but I too was a little surprised they didn't include a low range box.

I think they argued there was no need for high-low ranges because an EV has 100% of power and torque available from nought revs. Not sure about that, personally.

Qld is adding 18 extra EV chargers inland, in addition to the existing chargers on the coast north to Port Douglas and West to Toowoomba. The aim is to space the chargers about 200kms apart.

213 ft-lbs torque

so its about 300Nm of torque from zero. at 1000rpm my car is making about the same torque without low range.

i would guess/costs/complexity is keepng ev from having low range???

I think they just used the Tesla transmission. They had to replace the LR drive train because it was too weak to cope with the extra power of the Tesla.

There definetly is 100% torque from Zero , but the torque is not infinite. 100% power isnt achieved till well later , 5000RPM in my Landy , maybe 10,000RPM with a Tesla motor.
Power doesn't matter so much , torque is whats important . .

Think a Td5 Defender wanting to climb a vertical obstacle , like a rock , log , step or even a high kerb ( above centre of wheel)

lets do some maths . Td5 380Nm 2nd gear in a R380 = 2.132 Low TC = 3.321 Diff = 3.54 . 380 x 2.132 x 3.321 x 3.54 = 9,524Nm, (at axle)

my DIY EV only has 150 NM ,
I need 1st gear Low, for same 1st gear =3.6 low TC= 2.35 , Diff = 4.75 150 x 3.6 x 2.35 x 4.75 = 6027Nm

A Tesla P100D torque = 1250Nm , no transfer case x 3.54 Diff = 4425NM = would not climb out of a wet paper bag , or if your parked up against a rock you wont climb over it from a standstill.


My landy just sits at the bottom in low second which is coincidently about 4000Nm at the axle.

They used a tesla drive unit mounted longitudinal with a Quaife ATB in the diff , and driveshafts to the usual Defender diffs with 3.54 and ATB's.


Other Tesla to Defender conversions mount the Tesla motor onto the LT230 , which is the proper way to convert, unless you just want a street cruiser, which I expect most LandRovers in UK are anyway.

New electric Kombi on the way. It may not come to Australia, because VW said Australia's lack of supportive policy it would be 2023 before they would consider importing the IDBuzz, as the vehicle is called. The lack of vehicle emmissions regulation in Australia is considered the elephant in the room by VW, and other EV manufacturers. From The Driven;
