2012 Toyota FT-Bh Hybrid Concept

The study shows FT-Bh Toyota at the Geneva Motor Show, as a car with full hybrid drive can still make it more efficient. The car consumes just 2.1 liters fuel per 100 kilometers. The study shows Toyota FT-Bh at the Geneva Motor Show (8th to 18th March 2012), such as a car with full hybrid drive can still make it more efficient. The concept car is 3.99 meters longer than a Yaris. But while the newly introduced hybrid Yaris 3.5 liters per 100 kilometers fuel needs, comes from the FT-Bh with only 2.1 liters per 100 kilometers.


The weight of the study decreased by the use of high strength steels and light alloys to 786 kg. This is about a quarter less than the current Yaris weighs 1.0. The drive train is about 60 pounds very easily – the current Prius is about 100 pounds. Even with the bodywork, the interior of the chassis and the electronics mass was saved. Due to the low vehicle weight to reduce the forces acting on the body structure and chassis, allowing smaller components. Elsewhere, an improvement leads to further improvements in one place. As little cooling air is required, since the powertrain generates little heat. This in turn allows for a more aerodynamically efficient design of the front. In addition, the tank can fail due to low consumption compact, resulting in a better aerodynamic underbody design makes it possible – the demand drops again.

in the interior components were used, having either a low or a high heat absorption heat insulation. The air conditioning is only in the areas that are occupied. Moreover, the glazing has been thermally optimized. In addition, the energy requirement of the headlights and the interior lighting has been reduced to half. With the FT-Bh underscores the variability of the Toyota hybrid system. Other options in this regard, that manufacturer a natural gas hybrid (CNGHV), which is only 38 grams per kilometer CO2 would develop and improved plug-in hybrid with only 19 grams of CO2.


to low fuel consumption contributes to the good aerodynamics. Therefore, the wheels have been optimized, and cameras instead of mirrors to reduce wind resistance as well. Moreover, handle-free, electrically locking doors are used. Especially beautiful design of the FT-Bh is not yet sure of the drag coefficient is only 0.24. To further reduce the driving resistance is rolling the FT-Bh 145/55R18 on slender, large tires of the dimension.


Easier and more efficient hybrid system. The entire hybrid system with battery is about 90 pounds lighter than the current Prius. The internal combustion engine – a one-liter two-cylinder with so-called Atkinson-valve control – weighs 38 pounds less than the 1.8-liter engine in the Prius, and the lithium-ion battery is only about half the weight of the nickel-metal hydride battery of the Prius. The optimization of the combustion process are a long stroke, with a high 13:1 compression ratio, the D4-injection system from Toyota with very high injection pressure of 200 bar and an improved exhaust gas recirculation. We also use a flow-optimized intake tract and a particularly powerful ignition coil. The friction in the region of the belt and the electric water pump was also reduced.
