Toyota brought the FT-Bh Concept to the 2012 Geneva Motor Show to preview what it envisions will be its hybrid family supermini for 2020. The FT-Bh stands for ‘Future Toyota B-segment hybrid’. Toyota claims that it has a fuel economy rating of 134.5mpg and has CO2 emissions of 49g/km.
It is equipped with a two-cylinder, 1.0-litre petrol engine, which is developed specifically for the concept and is coupled to a special version of Toyota’s Hybrid Synergy Drive electric motor, which is nearly 90kg lighter than in the Prius. The size of the FT-Bh is similar to the Toyota Yaris.
Meanwhile, the car’s shape has been optimized for aerodynamic efficiency. It has a 0.235 drag coefficient, which is lower than the present average for a supermini. The 1.0-litre Yaris weighs 1030kg while the FT-Bh weighs only 786kg as it is built with high-tensile steel, aluminum and magnesium.
In addition, Toyota enhanced its thermal efficiency, low driving resistance and a drop in the energy level used by the car’s electrical parts. The FT-Bh was developed to be a CNG-powered car or a plug-in hybrid, which has 19g/km of CO2.
The FT-Bh is a show concept but it was developed using on-hand motor industry technology that could theoretically be rolled out with a competitive price for a high-volume B-segment supermini.
According to Koji Makino, project manager for Toyota’s advanced vehicle project, the vehicle may start production in the 2020s but to date, no concrete decision has been made yet. He clarified further that it will depend on the demand. What’s more likely to happen is that future cars will benefit from the FT-Bh’s lightweight, fuel-efficient elements.
