The lightweight, fully hybrid concept boasts Toyota's five pillars to maximize fuel efficiency and minimize emissions outputs. They are: mass reduction, optimum aerodynamics, powertrain efficiency, thermal energy management and electricity saving. We are talking a 50 percent drop in CO2 emissions than the run-of-the-mill five-door B-Segment model. The Japanese automaker says that the FT-Bh isn't just a car but a 'total vehicle approach designed to achieve low-emissions within an economically viable production framework.' The Toyota FT-Bh Concept will make its debut at the Geneva Motor Show on March 6th at 10:15am.
