Shown at previous Tokyo Motor Shows in 2001 and 2003, this is the third generation of the UFE. Dedicated to achieving minivehicle category-leading "ultra fuel economy," the UFE adopts a 3-seater package with light weight and extraordinary aerodynamic performance. Our development mission was to achieve 72km/litre*1 fuel economy.
Overall height is lowered to 1,200mm, with sleek styling to reduce air resistance. Applying aerodynamics simulation technology, we further optimized the shape of all body parts to thoroughly minimize drag.
The result is possibly the lowest*2 aerodynamic drag coefficient in the world for this class of minivehicle: 0.168, surpassing the 0.19 Cd figure of the UFE-II. Other notable efforts which enhance fuel economy are the composite polymer body and generous use of aluminum to reduce weight to 440kg, and the new 115/65R16 tires, which reduce rolling resistance.
For its power unit, the UFE-III uses a hybrid system comprising an engine and two electric motors. The newly developed 660cc inline 3-cylinder direct injection Atkinson engine offers an outstanding balance of output power, fuel economy, and clean emissions.
The electrical generator and drive motors are of the compact, lightweight, highly efficient AC synchronous motor type. Gear shifting is accomplished by a planetary gear mechanism and electrical generator, which function as an electronically controlled continuously variable transmission.
The techno-futuristic body styling has a streamlined super aerodynamic shape. While its pointed LED headlamps and canopy door create a next-generation impression, the bold window styling extending to the middle of the roof and smoothly contoured body surfaces contribute to a richly expressive presence.
The interior theme is high-tech with a human touch, providing comfort for three in a compact, futuristic space. Operational convenience is outstanding, thanks to steer-by-wire technology and placement of controls for easy access by the driver. To assist getting in and off, the instrument panel and front seat move up and down in linkage with the canopy door.
