I usually have the same passenger every time I drive our long-term Mini E. And every time, he hums along to the ascending whir of the electric motor on its way to its 12,500-rpm redline . And as soon as my foot comes off the throttle, he hums to the descending whir of the regenerative braking. It has become a joke between us. There's a mix of humor, wonder and resignation in the humming, I think. By wonder, I mean that electric motors do sound sort of cool. And by resignation, I mean that neither of us is yet ready for a world where all, or even half the cars, sound quite like this. Erin Riches, Senior Editor @ 2,699 miles
