BEV wheels seem to be part of the low wind resistance design. Helps with overall efficiency.

 

 

yep its all about rolling resistance and drag reduction - larger wheels that allow more airflow in to the wheel space increases drag and impacts battery life... my egolf has 16" wheels with less open areas to reduce airflow... not that I intend to put larger wheels on it but it would be interesting to see how much difference it would make.

 

 

What gets me with this, is why do we need evs to drive this design? It should be standard to increase efficiency across the board. We seem to make a big song and dance about the fuel cars use but if we can make the ICE versions more fuel efficient with the same design tweaks used to extract more range from a battery we absolutely should. It would make the ICE version cheaper to run and help contribute to emissions targets, not as much as changing fuel source but every little helps. It's that mentality that probably needs to shift, just because an ICE vehicle can drive distance and refill in minutes doesn't mean they should just be wasteful with consuming the fuel.

 

Aerodynamics was very much a thing in the 1980s with the likes of the Audi 100, Ford Sierra, Opel Omega and Subaru XT.
