Toyota’s new FT-Bh concept is a vehicle designed to take the efficiency of full hybrid vehicles to new heights. Making its debut at the Geneva Motor Show, it is an ultra-light concept, weighing less than 800kg, which demonstrates what can be achieved in terms of fuel consumption and CO2 emissions in an affordable family supermini.
Thanks to its low weight, exceptional aerodynamic quality, very low driving resistance and its highly efficient powertrain, FT-Bh can achieve an average 134.5mpg fuel consumption and 49g/km CO2 emissions.
Those figures are from a vehicle that is close in size to today’s Yaris, at 3,985mm long, 1,695mm wide and 1,400mm tall, with a 2,570mm wheelbase. The emissions are about half the level of those produced by a 1.0-litre Yaris.
The lightweight, two-cylinder, 1.0-litre Atkinson cycle petrol engine combines high efficiency with low thermal capacity and benefits with detailed measures to increase combustion efficiency and reduce friction. As a result, FT-Bh achieves an average fuel consumption of 134.5mpg and CO2emissions of just 49g/km.
