1000km range! I very much doubt it.

Too many variables! A bit like saying a car engine has 200 hp, but that is on a test bench, not on the road.

Conclusions

CLTC-P is relatively close to the acquisition data and the
acquisition data weighted by GIS, and in the middle,
reflecting that CLTC-P is in line with Chinese reality, and
is significantly different from other typical cycles. CLTCP is mainly in urban and suburban areas, which has the
characteristics of low average speed, high idle ratio and
frequent acceleration and deceleration.

Unfortunately I tend to agree. Anything like the ranges quoted (800-1,000 km) would certainly be a game changer in the EV market. No doubt it will get there, but my feeling is that we're some years away from it yet, as is the infrastructure around the world.

^Even if it manages 700km in real world driving it goes further than most people drive in a day.
Incidentally, the average car worldwide drives about 50km a day.

And here's another one:
Volkswagen-backed Gotion unveils new EV battery with 1,000 km range

Manufacturers quote range and mpg which can be used as a guide to what they might be able to achieve under perfect conditions, but the likelihood is that a car with a quoted range of 1,000 kms is going to give a real life range, quite a bit more than a car that has a quoted range of 700 kms.

Current battery technology range is limited by size so if you want to have a range of say 1,000 kms you need a really big battery - hopefully the batteries of tomorrow (solid state) will provide a much longer range than a same size battery today, or same range in a much smaller battery.

Apparently they are making higher capacity batteries by increasing the density rather than changing the chemistry:

I don’t think that it’s simply density increase Steve - they may well be increasing the energy density, but they are also changing the chemistry to some extent

Have you all noticed the latest about the effect of car tire rubber chemicals being much greater in Elect. cars (because of their weight) than in gas powered cars? In California their beginning to look closely at the effect of those chemicals as their getting into environment and washing into streams causing chemical pollution problems. From what I read the tire mfg. are aware of the problem and working to minimize the tire wear on the heavier elect. cars but the solution is a long way off as it is with other matters on the Elect. cars.
Of course, who cares about pollution in Thailand.

How is the curb weight of an EV, differ from ICE on the environment. Why would the tires be made any different. They're really getting silly.

MG ZS ICE ... Curb weight 1,290 kq
MG ZS EV ... Curb weight: 1,570 kg
Fortuner ... Kerb Weight 2180 Kg
Honda CR-V ... curb weight ,,, 3,201 kg

While searching, trying to find some article with reference to EV & tire pollution, I came across this silly headliner:
"Drivers beware: Some electric cars are so heavy they risk crushing smaller vehicles in collisions"
https://fortune.com/2023/01/11/electric ... accidents/
vs the #s I posted above, or vs getting hit by a 6-10-18 wheeler ...

I prefer not to be hit by anything bigger or heavier, but I prefer to be in an EV if hit, as the frame around the battery bank is made to take a good hit. Let that sink in.

[Dannie Boy]

Although I’m not going to join the argument about tyre pollution, you really ought to proof-read what you write KhunLA- how on earth could a Honda CRV weigh more than 3,000 kg?

^Yes, that's a silly argument. In America people drive around in V8 Dodge Rams and the like without worrying about the weight causing tyre pollution but now it's supposed to be an issue with EV's.

[brianks]

I too was a bit surprised when I first read about this tire pollution stuff several months ago in an article in LA Times. A toxic element in rubber tires was found in the water of a stream running next to the road to Yosemite Park.
Point is that it is the same for all car tires but only more so with EV's because of their weight and that they wear quicker because of this weight. Tire manufactures are aware of the situation and are trying to minimize or eliminate it in the future. Yes, fat chance when consumers are purchasing larger and heavier vehicles now.
Just another interesting development related to EV's that we will have to see how it all plays out.

Still not seeing the the 'extra wear' because it's an EV. Put the proper tire on the proper weight of any vehicle, and wear is the same. Reads like a bunch of BS to me.

2 cars, same weight, same tire, and they're implying the EV isn't as eco friendly. Pure silliness.
