I just made a mini you tube video testing my S+ on a 90 mile round trip on a warm summer day..no hvac at 90 km/hr (58mph on the cruise control). The EV01+ wheels certainly feel like they help. At 55mph, my SV+ would have only scene 4.3-4.4 tops on the same journey.

My gom was amazing by the end, though tough to drive so slow in 70-75mph traffic.

Very nice! I have read a little bit here about the EV01+ wheels but hadn't seen much in the way of testing before & after. So going from 4.4x to +5.x is actually a nice chunk of range on a long trip or a great way to negate the efficiency loss of running the climate control without affecting the total stock range. Seems to be a lot of ways to improve the Leaf range, little by little. It's too bad Nissan doesn't just bundle them all up into the next model and make it standard. What EV company wouldn't benefit from advertising increased range?

I will say that the run exceeded my expectations. I am not sure I have ever seen my gom that high, except when I got it.

Admittedly, no hvac, so take that into consideration. A worthy sacrifice for science. Also I had about a mile in either side after the freeway, so that might have added a tenth. 14.8 kWh for driving 92 miles or so, implies that on 55 usable kWh suggests 330 miles. I am eager to try a flatter run. Down state to see if I could do Skokie to St. Louis in one charge. That would be cool.

I had been anecdotally seeing earlier in the year (and cooler temps) seeing around 5 for some runs around 60mph (on the dash), but always without cruise amd was never sure if I was letting my speed slip. This was my first try with cruise control. It actually was pretty stable with very few spikes, rarely over 2 bars of power. (I did have to hit the brakes once for slow traffic on the way home).

Anyway, it's just one datapoint.

It's interesting that the wheel design can save so much, especially at such lower speeds than say trying to compare trips at +70 mph where air friction is really eating up power. The more test you do, the more you can be certain that it is a permanent range and efficiency boost. Tesla does it for a reason and it's less crazy than people think when you really do some comparison test.

Right...my curiosity is whether 80% of the efficiency difference between Leaf, Niro, M3 is in the rims themselves. Yes drag coefficient has, yes power train efficiency helps...but how much.

The rims collective are 40lbs lighter than the stock 17" rims, which I have to imagine help a healthy amount.

The secondary added benefit is reduced heat load on the battery. The temps on the battery never go more than 1 or 2 degrees above ambient.

I may be driving the Leaf to Baltimore this summer, which will require at least 2 very long QC stops (or 3-4 shorter stops) so qamt.to see if the temps manage better for a 700+ mile day or not. Guessing they will.

Yeah, once they get a place in the USA open so I can buy, I might actually pull the trigger since my Leaf is so new. Why not enjoy extra range and *style* to boot? ;)
