people need to learn kWh/100 mile. So if someone wants to charge their new EV…and they stop at a charging station, and the rate of electricity is 10 cents per kWh…magically they can figure out their cost to charge their car. MPGe just confuses people…because batteries, electricity, etc are all in kWh

If you know the kWh per 100 mile rating of a EV. It’s easy to know the cost of charging the car. Consumers need to know what kWh means. The lower the kWh per 100 a car is, the more efficient it is. The higher, the less efficient. So it’s simple for someone to figure out the cost to charge it. MPGe is a terrible thing, needs to go away.

For the knowledgable EV buyer, I agree that its not a metric that is needed. Most EV owners relate theoretical miles to battery size and electricity costs. They say my EV has a 300 mile range and 100kwh battery and my residential electricity costs 10 cents per kwh so for every 3 miles i travel, its 10 cents of cost. However, ICE owners don't explain their efficiency in those terms either. They say my car gets 20 miles to the gallon and they don't go that extra step of calculating on a per mile basis ($5 per gallon would be 25 cents per mile).
The MPGe was specifically created to bridge that gap because people are too lazy to go that extra step

kWH per 100 km makes as much sense as kWh per 100 miles.
Back to the original topic, it's great that Lexus has an 800V architecture, and I can see why they want to have it for the largest of batteries, but there's tremendous value for the people with under 100kWh batteries as well. I would argue that 800V architectures capable of ultra fast charging rates would mitigate the need for ultra large batteries. And if Hyundai/Kia can see to fit the technology in the Ioniq 5 and EV6, then nearly every EV from $40,000 or so should be able to incorporate it as well/

That's what I want to hear, Toyota/Lexus!

Typical Toyota/L, always gradual and slow behind everyone else. I wish they would at least try and keep up with the Germans like I know they can.....at least they don't try it and screw up royally like GM tends to.

Hyundai can put 800V architecture in a $40K IONIQ 5 that is on the roads and in consumer hands today. Should basically be table stakes for anyone else in that price range and up within the next 2-3 years.

I already made a thread on this last month. The major caveat being left out is that Lexus will only use this on large vehicles with 100 kWH batteries, so don't expect it to end up in anything like a sports sedan. Expect most Lexus EV's to be like the RZ.
