The car shown below is the UFE-II (Ultra Fuel Efficient), developed by Daihatsu (a sub-brand of Toyota), to act as a showcase for what is achievable with Toyota’s Hybrid Synergy Drive system. Unveiled at last years Tokyo Motorshow, the UFE-II achieved a remarkable 60km/litre on the Japan 10-15 mode drive cycle, which is equivalent to 140mpg (170mpg, UK)!

The drivetrain is a 660cc Atkinson cycle petrol engine mated to two electric motors and a nickel-metal hydride battery – so is likely to be a scaled down version of the system used in the Prius. The body is made of aluminum and resin, such that the entire vehicle weighs only 570 Kg. This is a remarkable achievement in itself, as the UFE-II has been designed to seat 4 adults!

Of particular interest, however, is the aerodynamic coefficient, which at 0.19 is the lowest seen on any road car since general motors EV1.



Aircraft designers and aerodynamicists have a saying “If it looks right, it’ll fly right.” To my eyes at least, for a 4-seater car, this has to be as good as it gets! 8)
