The Daihatsu e:S concept. Click to enlarge.

Daihatsu Motor, Toyota Motor’s minicar specialist, will exhibit six concept cars of four different vehicle series and nine production vehicles along with new technologies at the 41^st Tokyo Motor Show to be held from 24 October to 4 November.

One of those, the e:S (eco & smart) concept achieves high fuel efficiency of 30 km/liter [70.6 mpg US, 3.33 L/100 km] (10-15 test cycle, measured by Daihatsu) through improvements to existing technologies and the use of a start-stop system—i.e., keeping the cost down while providing fuel consumption competitive with hybrids. (Earlier post.)

The e:S is based on a current platform with the wheelbase shortened to 2,175 mm. Although it has compact exterior dimensions, the package can accommodate four adult passengers.

In addition to a compact body, the use of slim, lightweight seats and the replacement of many materials with lighter versions limits total vehicle weight to 700 kg (1,500 lbs). The e:S is equipped with a conventional 660 cc minivehicle engine fitted with a combustion control system developed by Daihatsu and an EGR, as well as an Idling Stop System.

Another concept, the Tanto Exe, is based on the Tanto which continues to enjoy strong sales and features a lighter body and higher fuel efficiency. Daihatsu plans a market release for the Tanto Exe in the future.
