But Honda is playing it very close to the vest, so that's all we know. Is it hybrid? Plug-in hybrid? Fully electric (maybe they liked Tesla Motors' strategy of introducing electric cars upmarket first)? Your guess is as good as ours. You can read the press release if you are curious, but it's not that interesting without details on the drivetrain (we also want details on the drivetrain of Honda's upcoming hybrid). In the meantime, enjoy the photos (more below). On this image we can see what looks like a tailpipe in the center, so that makes the probabilities that this is an all-electric car lower. But it could be purely cosmetic, or it could be removed if the car ever becomes a production model. The dash is clearly inspired by the Honda Civic and the Honda FCX Clarity.
