Electric 4WD

[ol' boy]

Been keen to see EV's move into the proper 4WD market
Although a long way to go, amazing how many orders this company has for a 4WD that looks like a 4 year olds drawing.

OMG looks like someone vomited up a Landrover !!

Was reading about this last year in 4X4 Australia magazine. EV’s will definitely bring a lot to the off-road market, especially in regards to power and torque.

The limiting factors for electric off-road vehicles, and in many respects ‘regular’ EV’s, is range and recharge. With its standard battery this thing will only go 200km (120mi) before a recharge, fine for around town, but simply not enough for a long range off-road vehicle.

Plus I don’t know how those electronic motors would go through muddy river crossings....

Agreed, and 4WD's already suffer from being over weight easily
GVM would always be an issue.

I think Dakar has had an Electric entry for a few years now, its not really competitive, just there to prove it can be done.

Hybrid 4wd's will give best of both but be a while until a proper 4wd will be fully electric.

It'll do a 1000 miles............ If you tow a power station with you. I think the most attractive part of this car is the seats...........

The instant torque that an electric motor produces will be handy off road if they can get a decent range from new tech batteries.

How the hell can you call this vehicle 'Environmentally Friendly' when it needs be recharged either of the Mains or a petrol/diesel generator belching out Carbon Monoxide

Yes, the fact power - generally provided by coal - is needed to recharge is always the part the brochures fail to mention.

However, in general, the emissions emitted from the power produced to charge an EV is less than the emissions put out from the production then use of fossil fuel. There are definite environmental savings there.

Plus EV’s don’t use oils or fluids in their engines in the same way, so there are further environmental savings there.

Also, charging an EV via ones home solar panels is entirely possible. If you did so you could basically get away with a close to zero emission vehicle.

Back in the late 50's was there a concept for both a vehicle and a Motor Cycle using a Nuclear powerpack that drove ALL wheels electrically.
This was more about the use of Nuclear energy rather than using electricity or the 'Saving' the planet.

On both vehicles, each had an electric motor mounted in the Hub to drive the wheels.
It when on about the weight saved as you didnt have an engine or drive train but neglected to mention you need a 'Containment' roughly the size and mass of at least a Double Decker Bus or you could tend to 'Glow' after a nice Sunday afternoon drive.

Today you substitute batteries in place of the Nuclear power pack but you have their limits on their capacity to take you any appreciable distances and ability to recharge them.

I do like the idea of each wheel being electrically driven but I cant say I am that keen on a Hybrid system as it must make the vehicle heavier by the addition of the Batteries.

Every day we see examples of a Fuel Engine driving a Generator/Alternator and an electric motor driving an axle on Railway locomotives so the concept is feasable.

I love it, looks good, 0-100Km in 4.7 means its no slouch, instant torque, the list goes on, 200miles on the battery option means its got some street distance (but doubtful its 200 miles of 4x4 offroad).

But what about water crossings?

Motor and batteries water proof?

That flat roof would work well to be covered in solar panels that can charge while its parked outside......

[ol' boy]

Well the 79 Series is to be used underground, so fantastic with no emissions in that environment.
Water Crossing, no problems, i inspected the Aciona EV 4WD Rally car last month, it goes through water fine

[gordon_s1942]

I think the only concern I would have with electric motors mounted in the hubs is heat dissipation.
Running through water would cool them nicely but under load slogging up a Sand Dune in 40 C ambient air temp would need good thermal heat dispersal as venting them would not be an option.
Railway Diesel Electrics have fans blowing air into the motor casing which is why they wont go through water 100mm over the Rail head.
There would always be the danger of ripping off any air ducting to a hub on a 4WD due to where they may be used.

Wouldn't like to be underground when those battery packs short out and catch fire.....

That could be said for any vehicle used underground?

Why not sealed / water-cooled motors
Like some Alternators already are :-)

Yes, but the fire suppression systems on current underground vehicles puts them out very quickly.
Lithium battery packs tend to spew out clouds of toxic gases and are very difficult to extinguish once they get a hold.
They would no doubt be able to fit them with a suitable fire suppression system.

I like the extra storage in the front boot!
