Insight look-alike achieves 140mpg!

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)

Hi,

About the tires (and from our experience in the Insight), those tires will have a lot of pressure in them, surely above 50 psi and will not make a comfortable ride on real world roads.

I bet braking a wheel will cost a lot. Here the price of an Insight wheel is about $700 cnd while a steel rim is about $40.

And the rear passengers are probably going to be very tight.

For size and comfort, I think that car makers can not go farther than the Insight if they want to sell and not stay a concept car.

Improvement in the drivetrain is the only way to go.

My 2 cents.

Hi,

And notice where the rear wheels are, definitly less distance between the rear. Rear and front wheels do not share the same track (as per the Insight, they are off centered)

The car is very narrow in the back for the passengers.
