Let's do some rough maths.

There are several $50,000 EVs around with many more coming, which is cheaper than a typical Hilux, Ranger or similar ute.
Let's say a person commutes 70km each way or 140km a day or 700kms in a 5 day week.
Let's say their vehicle uses 10 l/100kms, so that's 70 litres, at let's say $2 a litre is $140 pw on fuel is $7800 a year.

Now let's say the person spends $50k on an EV with a typical 300km range.
Each day they get home and recharge the vehicle, which is on about 50% of its 300km range, so it should recharge in an hour or less.
How much does 5 hours of recharging cost? If the sun is shining, effectively nothing. But just for the argument, let's say it costs $3 x 5 = $15.

So instead of paying $140 pw or $7800 a year, they are now paying $15pw or $780 a year.
The annual savings is $7800 - 780 = $7020. So the fuel savings alone would pay for the vehicle in about 7 years.
That doesn't include servicing savings, which for an EV should typically be about half, since its just oils, brakes and tyres.

These are all rounded averages of course, but even if you fiddle with them, for example saying fuel is cheaper or consumption is lower or charging costs less, when boiled down the EV still comes out way ahead.

Nice… I have some thoughts on this though.

In coming years the grid will require major upgrades to keep up with the demand - this will be pushed onto consumers so expect that $ figure to go up by a factor of 5-10 (in the Uk power bills are now £400)

There’s already talk (and I believe action) on charges to cover lost Fuel Excise - so add that on - that’ll be likely to be a kilometre based fee.

Maintenance is an interesting one, of the few EV owners here in town, one thing seems higher - perhaps Navy Diver can give his experience - the heavier than normal for class weight of the batteries etc is seemingly having an impact on tyre life.
One owner here tells me his EV is wearing tyres in about 2/3 the distance that his previous ICE vehicle (same make/model) would.

Range isn’t real either - so 300km is likely 170km on a hot summers day (or a freezing cold one). That becomes a margin call - and increases charge time by double.

I’ve run numbers on the longest range EV, even with the 8yr 80% figure - I cannot keep one for more than 3-4 years before it can no longer meet my distance requirements.

Yes, ours has a separate line upgrade to the mains.

Unless you want upgrades to the mains,etc,etc.

Yes my tyre guy said the same thing the other day,tyre life is very short,his comment was tyre companies will have to lift their game.

As I have said before,a mate has ordered a RRS 510E.It is PHEV,so only has a small battery,and petrol motor,but weighs something like 450 KG more than the equivalent Diesel model.

Another thing is when it is running on petrol,due to all the extra weight it will use a lot more fuel than the current petrol only model.

Give us a call when you are out of power

"I just drove past a Tesla on the side of the road with a little generator going 😂😂"

Wasn't that the whole concept, in that one towed a trailer behind which was fitted with a Gennie?
One saved on emitting Pollution & buying fuel.
I suspect there was summat wrong with that idea.

Yep house with a red roof with solar panels, you can't miss us.

We noticed it as well, last time we flew in.

I am sure there was some old codjer with very few clothes on, sunbaking by the pool.

Maybe part of the vehicle tool kit will be a small gennie?

Yep, instead of Jumper Leads.

An odd method exists to start MAZDAs & probably others as well, not like just chuck the leads on & away you go.

RAA geezer showed me what to do & in fact it won't start at all if you do that. It's quite weird.

Are you sure it wasn't a Land Rover?

Quite sure. The 2A was sitting next to the Maz & he couldn't but help compare the 1966 Technology to the 4 year old Maz.
It did look remarkably different to say the least.

If you are unfamiliar with the "How to Start with a Semi- Flat Battery" sequence I'm happy to post up the sequence but I guess that anyone here who owns a late Model vehicle would/should be. Maybe? I have needed to do it twice.
It was because I drove Land Rovers or HOLDEN products. Oh & ToyMotas where you just heaved the Battery Cables out & used them.

That was next doors. We can't afford a Pool.

Flying in? You'd be in strife if that happened, Flight Path here is deffo Outbound only for large Jets. Lots of choppers & some Privates though, both ways down low.
