Huh.
I guess it’s costing me about 5p per 100km and it’s not going to bankrupt me, but it’s definitely a lot more than I expected. Thanks for the link. There are some interesting articles in there.
Still think the ones with 8lb motors in them are a complete waste and can fail too easily but them being flush doesn’t seem like as much of the problem as it being motorized which is the part I personally believe they should correct
According to this the average EV uses just under 18.9kWh for 100km. 0.6kWh is over 3%.
I find it really really hard to believe that regular door handles cost 3% of your energy. I suspect that’s a massive over estimate.
I got the number from here
“Engineers say that drag reduction due to flush handles amounts to just 0.005-0.01 Cd, saving about 0.6 kWh per 100 km.“
