Just like Rome wasn't built in just one day, the Toyota Mirai fuel cell EV didn't just show up after last night's rain. This is exactly what Toyota wants us to know in their latest video uploaded on the Toyota Europe Youtube Channel. From the video, we find out "downsizing generates new possibilities" but they're not talking about engines here. What Toyota wants to draw attention to is how their research over the years found its way into the Mirai FCEV. Also in the video below you'll be able to see how power output constantly increased since 1996, as fuel cell stacks became smaller and more efficient. Source
