Mercedes EV POC: 747 Miles Single Charge

[mzflorida]

Many contributors here seem to be interested in electric vehicles, generally, including myself. Anyhow, this popped up in one of my automobile forums. 747 miles from an EV. It’s a prototype that goes more to proof of concept than practical application to production models but still promising. https://www.autoweek.com/news/green-cars/a40406500/mercedes-eqxx-ev-beats-record-747-miles/

That’s good news. Thanks for sharing.

I didn’t do a deep analysis, but besides the Mercedes car having a large battery, it’s efficiency seems to be the key to it’s range. It seems some EV’s today, such as perhaps a Rivian truck, are not overall practical designs/platforms for using the battery power efficiently, thus limiting their range.

I drew the same conclusion. The drag coefficient of the vehicle and the capacity of the battery were significant to achieving the range. So, to achieve the same in the Rivian without changing Cd, you would have to have more (maybe much more) than 100Kwh available in the form factor of the current battery. It will get there but who knows when?

Agree.

People can argue about the pros and cons of energy sources and types used for transportation, but simply using less energy altogether seems most important to me. Making vehicles more efficient, as seen in this Mercedes example, should be a universal goal.

That is 100% accurate and inarguable. Electric vehicles may not ultimately be the answer but the goal is spot on.
