Overview:

Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

Bold claims on Density/Range (www.techradar.com)

Bold claims, but that energy density would be amazing.

Are you talking about the Lucid Air? Stated EPA range is 512.

The only Mercedes I found with a 1000 figure was 1000 km or 626 miles for the Mercedes Vision EQXX concept.

But my search prowess isn't what it used to be. I'd love if you could provide the models.

I wrote near 1000 km. But above 800 km mixed, and above 950 in good conditions, on a single charge on currently available production cars, is pretty close IMO.

https://ev-database.org/car/2193/Mercedes-Benz-EQS-450plus
WLTP 825
City - Mild Weather 955 km

https://ev-database.org/car/1696/Lucid-Air-Dream-Edition-R
WLTP 828 km
City - Mild Weather 960 km

This is how I sorted:
https://ev-database.org/compare/electric-vehicle-longest-range#group=vehicle-group&rs-pr=10000_100000&rs-er=650_1000&rs-ld=700_1000&rs-ac=2_23&rs-dcfc=0_300&rs-ub=10_200&rs-tw=0_2500&rs-ef=100_350&rs-sa=-1_5&rs-w=1000_3500&rs-c=0_5000&rs-y=2010_2030&s=6&p=0-10

I did not count concept cars, because I know there has been some pretty crazy concept cars made, that will NEVER be possible to buy.

So the EQXX should do about six miles per kWh. Which isn't far off double the efficiency of your normal EV this size and performance.

That double efficiency comes at extreme cost of materials the car is built with, and probably also lacking equipment that is normally present. Also if I remember correctly, the battery is not production ready, and does not have good durability.

Thank you.

I wrote near 1000 km.

My bad, misread that as miles.

Still, I think is safe to assume those batteries are on the higher end of energy density, so the Huawei battery would be something like twice the density (which, again, amazing). So those would be upgraded to 2000 km with the new tech.

I agree 3000 km sounds pretty crazy, even if possible, almost nobody needs that.
So instead it will be a cheaper smaller lighter battery, with probably around 600 km range in average cars.
The real issue here is not 3000 km because that's irrelevant, the issue is whether they can make better prices, security and fast charging.
The 3000 km is just a number to sound impressive.
