This particular range test was performed with the less efficient 20” wheels. So should be fair to assume 24 additional miles of range with 19” wheels.What is interesting is the warnings to put hands back on the wheel. He did this in both reviews, the noises should get people to wake up hopefully. I understand it's a capacitive touch wheel.
If this buffer is done the same way as in the Leaf, I actually found that to be one of the most frustrating 'features' of that car. In the Leaf, this buffer is included in the range estimate at high state of charge, but below 60% the car progressively hides more of it. As a result, your range at a full charge always looks overly optimistic, and then range starts to disappear faster than expected. If you use something like LeafSpy you can monitor your true state of charge and see the estimated range drop more linearly. I assume Nissan did that with the Leaf so that owners would see range roughly consistent with the advertised range when they had a full charge (and during EPA testing), but would be discouraged from actually using all of the available battery for longevity.He did another test where he ran it to zero. Pretty cool that you've got a good amount of buffer in case of an emergency.
