Yes, air resistance increases as the square of the velocity.
Nissan, the maker of our LEAF, had the guts to say in the owner's manual, that maximum range would be achieved at 37 mph, the sweet spot for that vehicle of going before putting too much energy into overcoming air resistance.
I think I've just decreased the mileage even more, by installing the tall windshield.
And I'm on my third tune from
@HansO , this latest a request to lean it below 3,000 rpm -- on my Touring that is a hair over 75 mph (as reported by the navigator tied to GPS).
My challenge this summer will be to install
@Neville Lush "street" cams, *and* take it to the local tuner (to quote Nev, "It can't be that hard." -- we'll see), and re-check the consumption. I suspect at that point, I'll be done, and the Rocket will be what it will be. I still have two no-longer made
1/2 gal Tour Tanks that I have carried, and have yet to need.
Side note about the sad state of lack of responsibility: I called the guy who makes the Tour Tanks (now Coyote Products) and asked him why they no longer offer the 1/2 gallon model. He told me that idiots bought the tank, didn't understand expansion, had gasoline spilled when opening the container, and threatened to sue, and he couldn't afford the liability.
