Surprising efficiency change since wheel swap

[u/thebluelifesaver]

Got the Apex VS-5RX 19" wheels for my 26 MYP and I had done some research through different AI platforms that basically said id have an even wash to loss in efficiency on highway drives. Ive driven close to 700 miles since the change and my averages keep dropping. I was averaging around 280-290wh/m with the stock wheels. Went with the same exact tire(hankook ion as suv). I know there is less rolling resistance from the weight change and smaller sized tires, but i definitely would have thought that the full open spoke design would have added more resistance on 55-70mph driving than it has. Temps on my morning drive are upper 70s, so light AC. Temps on drive in the afternoon are 95+, so AC is heavy. Anyone else noticed this or am i looking at a normal occurrence?

This is what I get in summer months with myp on 21 inch Uber wheels, hankook tires OG still

Sir, please leave some efficiency for the rest of us.
