FT-Bh (Japan, 2012)

Toyota is hoping to revolutionize small cars with the new FT-Bh concept. The concept uses available materials in new ways to offer a total weight of 786kg, despite being larger than a Yaris. It is highly aerodynamic with a 0.235 drag coefficient. 

Power for the FT-Bh comes from a two-cylinder, 1.0 liter hybrid powertrain that uses 1.7l/100km and emits just 49g/km of CO2. That is about half of what is produced by a 1.0 liter Yaris, but the FT-Bh is 3.985m long, 1.695m wide and 1.4m tall. 

Toyota said that it would be possible to link the hybrid system up to a natural gas-fueled engine that would emit 38g/km of CO2 or a plug-in hybrid system that would lower emissions to 19g/km of CO2, but the plug-in hybrid would also raise weight. 

The achieve the weight loss, Toyota used high-strength steel, aluminum and magnesium. The combined weight of the engine, suspension and interior is 340kg, which had a huge effect on weight savings, becaus...
