Daihatsu has revealed the first details about the e:S concept, ahead of the Tokyo Motor Show.

Designed to be eco-friendly, the concept is a small three-door hatchback with attractive styling. The overall design says Toyota iQ (which it may be based on), but somehow the e:S gives the impression of a "legitimate" car.

While details are limited, the company says the e:S has a 2,175mm (85.6") wheelbase and a total weight of 700kg (1543.2 lbs).

Power comes from an 0.65L (660cc) 3-cylinder petrol engine, outfitted with a start/stop system, that returns approximately 30km/liter (70.6 mpg).

Look for more information to be released when Daihatsu officially unveils the concept later this month.
