Toyota revealed their latest plug-in electric concept car here in Tokyo as the FT-EV II. This one is a followup to the iQ-based FT-EV that we saw in Detroit but appears to be a ground-up design that takes advantage of the electric drive architecture. The iQ is promoted as a 3+1 layout because the presence of the steering column and instrument cluster force the driver's seat to be further back limiting the already small rear seat behind it.
The new concept uses a complete fly-by-wire system with joystick-like controls that feature a steam-punk design motif. The result is wide open space in the front and the very thin shell seats result in decent room. The car also has sliding doors on both sides. It's not known if this concept represents a design direction for an urban BEV that Toyota will likely build to meet ZEV mandates in the next five years, but it would make sense to do a custom design.
