just awesome, the corvair with its silver zinc battery is just staggering.

Yes. Yes it is. I think perhaps the correct phrase might be less inefficient.

The problem is with diesel that they used to be incredibly slow. Once we'd put turbos on them though they could give reasonable performance.

But the unfortunate bit about humans being humans is we just used this new technolology to buy bigger cars that weren't feasible to power with petrol due to consumption. I've ranted over and over about this as we all know.. Australians (although it's a world wide phenomenon) drive far far bigger cars now than we did even 20 years ago.

So yes, a diesel prado on the school run uses a lot less petrol than a V8 rangie did, but it doesn't use less than Mum's Laser. Yet Mums choose the prado/Ranger/Hilux. Only a few years before Mums Laser the kids rode or walked to school. It should be noted that mum having a Laser was also an escallation.
So while diesel is more efficient our average fuel consumption has actually increased.

Also due to car centric thinking and poor urban planing in our cities people drive more.

So despite over 10% of cars being EV's they have not as yet been enough to even stop the growth in fuel use let alone decrease it.

It should be noted that EV's do not fix many of the other car problems. It could be argued that these are just another Jevons Paradox step. If/when we get the autonomous driving thing happening and people start asking their car to "Hey car - park at home today on charge and then come and pick me up after work at 5" we're really going to see some issues in our cities. I don't think this is very far off either.

It should be noted that the best outcome on many levels is living locally. Walking, riding, PT use and avoiding car trips.

EDIT: one thing about diesel that I didn't mention.. co2 is a significant aspect of emissions. But diesel has lots of nasty byproducts. Making diesels comply with these regs results in less power and efficiency (diselgate anyone). It also increases complexity and reduces durability. Historically I think a lot the diesel advantage was just due to poor emissions control.

The Sales rep from Isuzu said this to me last week,as well.

So it must be true....

That's the kind of thing the guys at VW used to say too.

In thinking about my post above.. I actually don't think EV's have a big change to efficiency coming. I'm sure batteries will improve but I'm not sure efficiency will make big leaps.

At the moment tesla is the clear efficiency benchmark, and they only sell large cars probably for commercial reasons. At the moment if you buy the smallest EV on the market - an Atto 1 it actually uses more energy than a Tesla Model Y. It's nuts.

It would appear that until someone puts the good bits in a small car we're a bit stuck.

A couple of Tid Bits from my recent travels.
1 friend in Brissy knows a millionaire well who bought AFAIK a Tesla X or Y. Battery failed at about 8 years and quoted $40K to fix by Tesla. Reason given was apparently that car had to be shipped to Japan for battery replacement!
So being a millionaire he just bought another one and kept the first for spares.

Camping yesterday at Halifax at Nelson Bay. Lady at next site has a Ranger hybrid. Loves it and claims 6L per100Km and 12.5 towing horse float. Says on hills like Moonbi Range is great as charges while going downhill. Must live near Tamworth as says goes to the shops for free. So not only city centric. Says only! cost $76K only 6K over diesel Ranger. I wonder if they plan an Everest hybrid?

They have to,with the way NVES is structured,or drop the model.
But in an existing wagon it is very difficult to find the space for the battery and associated bits and pieces.
As can be seen with the dumb arsed set up in the 7 seat Prado.

The fist story.. The model Y was first sold in Australia in 2022. So probably a model X. The only connection I can find with Japan is panasonic made the cells. I've never heard of anything like this.. in any of the owner groups etc. No idea. The tesla battery warranty has always been 8 years BTW. It's also very unusual for packs to fail completely .. especially at only 8 years old. Not enough details

As to the ranger hybrid. I'm glad she's enjoying it. There are use cases for them. I think they are very very slim but if it's working for people that's great. There is commuter rural area near me called samford. I see Sharks pulling horsefloats on the weekend, and then driving to work during the week. I guess if that works.
