For all of its newfangled technology, the Mirai drives no differently than a normal battery-electric vehicle, which is to say it feels heavy, synthetic, and utterly free of drama. On our brief drive opportunity in Newport Beach, California, we noted acceleration that starts out spry but drops off drastically as one approaches highway speeds. Toyota’s claim that the Mirai can hit 60 mph in nine seconds flat is entirely believable based on our short bursts of acceleration and our brief freeway hop, although we’ll have to take Toyota’s word that it can touch 111 mph, as we never saw more than 75. All the while, the powertrain is utterly silent save for some muted gear whine, which in turn makes other sources of sound, such as the tires on the pavement and even the HVAC system, seem louder
