My concern with this is that it's a bit hypocritical.. It's basically turning the EV into a hybrid, but gensets are (usually) much less efficient and less clean than ICEs in production vehicles, and towing a trailer in itself sucks up energy.
What car ICEs are you talking about? You mean the things that are bristling with emissions equipment, and running water pumps and such. Sorry, a generator running at peak torque all day long is way more efficient, as it's at its most efficeient load all the time, where as non-CVT car engines are usually majorly compromised. E.g. My 200SX engine (SR20DET) has peak efficiency (off boost) around 5000rpm, yet it idles along on the freeway at around 3000rpm, so at best its going to achieve around 7L/100km (run from full to empty on the freeway without stops)
If it were a NA SR20DE, it'd get more like 5, but that's due to the lower compression in the turbo engine making the power delivery less efficient unless on boost.
Now lets look at a 2-litre petrol gen, or 2-litre diesel gen. We're talking probably something like 5-litres and 3-litres respectively per 100km humming along. These motors are tuned for efficiency at peak torque, so have a very peaky powerband, and hence are not compromised at all. Maybe if you were talking a BMW M5 engine with its infinitely variable timing and lift, you might have a point... But there are very few engines like that, especially of the fuel efficient economical kind.
...and I always thought hybrid was a multi-drive system like the old Priuses, that have a ICE crank and an electric motor to the driveshaft rather than multi-powered electric drive systems.
Surely you're not saying that a solar car is a hybrid because it doesn't rely on its batteries alone??? Does that make "electric" trains a non-EV because they use grid power directly?
I think regardless of the power source, if the drive is an electric motor, then we're talking an electric vehicle.
Perhaps this is off topic, but without going into purist values of what is a hybrid and what is an electric vehicle, the aim is to get the vehicles from Perth to Canberra, and there is no means without taking months to do it, of getting them here under electric-only power - even by train, which is diesel.

Yes in the past I've sent cars in both directions, sending them east (Perth to Canberra for example) isn't too bad, but sending cars West costs about twice as much! Apparently because there's more "stuff" coming west than going east, so there's more free space on the eastbound trucks, making it cheaper.
The train to Sydney + 300km option is sounding good to me.. That is, if I haven't managed to build my Hypermiler in time..
Keep in mind that the return trip will be twice as expensive by train too...
That and you should note that there are some serious hills on the leg from Sydney to Canberra, so keep in mind, that unless you have regen braking, you're going to use alot more power than you save going down hill, going up the hills...
It might be worth setting a minimum range capability for cars coming from Sydney in the convoy, and then setting a 75% safety margin (if the range is 100km, only travel 75km at a time).
Also, has anyone considered the media effect of a convoy of EVs with gen sets travelling across the nullabor? it would be great coverage on the lead-up to the open day...
Just my 2c worth - not wishing to offend anyone, just my view...
