if you had 4 x 20 hp motors - one on each corner - would that mean an 80 hp series land rover? and all that torque from zero RPM.
sounds like you might be able to pass something on the highway with that...wait until the electric vespa thing is available second hand and give it a go...
"wait until the electric vespa thing is available second hand and give it a go..."
They are on the market now, just bought one :D
not going to butcher it though. I'm in hippy heaven right now :)
A couple of points here
the higher the voltage the lower the current that is why most hybrid cars run a voltage of around 400V, so that the cables aren't as thick as your arm.
A/C motors require tricky controllers to change the speed (read expensive)
A DC motor is easier to control the speed but there are more moving parts i.e. brushes, so it wears out faster.
If I had the money - 3 phase 400V 20 hp water proof motor on each corner powered by a diesel running an altenator, controlled by a Variable Frequency Drive and standard wheel spin detectors
that will set you back about 30KQuote:

On the other hand I do feel a little adversion with respect to its consumption and oil based fuels in general. Both as a bit of an environmental aware hippie.... and looking at my wallet.
Would it be possible, for this car or for a LWB series II, to just take out the engine and replace it with a second hand hybrid engine of say a Toyota Prius? (Maybe of a crashed car)
Would you then needed to do the same with the transmission?
How flexible are Hybrid engines in fitting it into other models?
Or would you need to change the whole drivetrain etc.? (in which case you might as well take the body of a Series and place it on top of the base of a Prius)
Just some thoughts and questions....
I'm not a massive fan of the Prius in theory and I wasn't all that impressed in practice either when I got to drive one as my wife's Corolla gets better economy on the same run to work over a week.Quote:

With an all electric car, your not carrying a petrol/diesel (ICE) engine, don't need a gearbox and you can distribute the weight around the car so it rides nice and balanced.
With a ICE car you have the engine, gearbox, fuel etc but no batteries.
With the Prius, when it is powered by electric it is also dragging the petrol engine and when on petrol it's dragging the batteries and a heavy electric motor so it's robbing peter to pay Paul so to speak, and on top of that, you need to run the engine to charge the cell which again is burning fuel.
The controller from the prius is very complicated from what I have seen but I haven't read much on them so I don't know much there.
There are a couple of other negatives with the prius as far as being fairly non environmentally friendly.
1. The batteries will still be here when man is extinct
2. They use on average as much or more fuel than a comparable sized ICE car.
There are plenty of good systems out there but none are really cheap but most commercial motors are easier to adapt for this sort of thing than purpose built stuff normally.
Forklifts and Golf carts run electric controllers and even some electric ride on mowers do as well so if you buy a second hand one with dead batteries then you will get a controller and charger rather cheap.
Trojan lead acid batteries for a golf cart (48v 30ah cell) costs about $2500 and if used properly will last about 3 to 5 years and in the industry are costed in as fuel as they use about $1.50 of electricity off peak to charge.
There are a hell of a lot more brushless motor coming out on all sorts of things and LiFepo4 cells (which are much easier to recycle than standard Lithium batteries) are getting cheaper and more accessible from China so hopefully so we will see more commercially available options coming into the Aussie market at a reasonable price.
Yep, bugger hybrids. electric only is the way to go.
My vectrix is pretty good. adequate performance, limited range, but an excellent inner city commuter.
there is more and better in the pipe line
i am in love:
TESLA - Model S
The biggest problem is the Prius is front wheel drive and the 2 engines and the transmission are very well integrated AFAIK.Quote:

The prius is great under stop-start conditions (i.e. city driving), but outside of that is the same or worse than other equivalent size vehicles. IMHO, a better option would be to use something like a freelander diesel (best option would be the new TD4e diesel - with the stop-start feature).
Yes the point is moot for us series drivers because literally everything on the road including fully loaded B doubles are faster, so even with the technology discussed here to overtake,say going up along gradient, you would have to keep it all switched on to prevent the overtaken rig from rounding you up again once the hill flattens out.Quote:

Wagoo.
I'm thinking you'd want a tdi just under 2 litres to get adequate power for constant power running (i.e. top speed). A vw 1.9 tdi would do the job nicely, it's the most efficient diesel of it's size too.Quote:
