The hybrid's aerodynamic shape and efficient powertrain also contribute to the reduction. While the FT-Bh isn't headed to production any time soon, there's a good chance some of the vehicle's tricks may show up on consumer models in the near future. Hit the jump to check out a short teaser video and the press release, and be sure to stay tuned for our live Geneva Motor Show coverage.
FT-Bh - Future Toyota B-segment hybrid
New concept designed for maximum fuel efficiency, built using economically viable methods and materials
CO2 emissions around 50 per cent lower than the current average for the supermini segment
Focus on five principal factors: low weight, aerodynamic performance, powertrain efficiency, thermal energy management and electricity saving
World debut at the Geneva motor show
Toyota's FT-Bh concept breaks new boundaries in small car efficiency. It's as spacious as an average five-door supermini, but produces about 50 per cent less CO2, and tipping the scales at under 800kg, its weighs less than a three-door Aygo.
These feats have not been achieved by using exotic materials or expensive techniques: from the outset Toyota determined that the FT-Bh would be made using commonplace, economically viable production methods and technologies, including a down-sized full hybrid powertrain.
Toyota took a "total vehicle" approach, focusing on five areas of design and engineering to gain the highest fuel efficiency and lowest emissions: weight reduction, optimum aerodynamic performance (achieving a 30 per cent gain), powertrain efficiency, thermal energy management and electricity saving.
The FT-Bh concept makes its world debut at the Geneva motor show, at 10.15am on 6 March.
