It's set to show even more hybrids at the upcoming 2012 Geneva Motor Show.
As well as the sleek NS4 Plug-in Hybrid Concept, Toyota has teased the FT-Bh, a city car concept, which Toyota says showcases a "total vehicle" approach to reducing emissions in an affordable city car.
The teaser image is rather... err... "cryptic", but it does suggest a gentle sloping roofline, just like the more familiar Prius. Sharp creases and a wheel at each corner appears to be the order of the day, in a one-box design to maximize interior space.
The FT-Bh is designed to be ultra-lightweight, to give the full hybrid system as little work to do as possible, increasing fuel efficiency. The design team has deliberately avoided expensive materials though, so the concept is unlikely to have a BMW i3-style carbon fiber and aluminum structure.
We expect more details on the FT-Bh to trickle out in the days running up to the Geneva show, and we'll bring you live images and information from the show itself, in early March.
