Toyota’s daughter brand of small vehicles, Daihatsu, has launched a new version of its Mira kei car called e:S incorporating a raft of new or revised technologies, all of which aim to improve fuel efficiency.

Daihatsu says that it has overhauled all existing aspects of the engine, the transmission, and the body structure, to make the most of energy efficiency and as a result, says that the Mira e:S is almost 40 percent more fuel efficient that current mini cars with engine displacements of up to 660 cc [0.6-liter].

The Mira e:S is powered by a three-cylinder 650cc gasoline engine that produces an output of 52PS (51HP) at 6,800rpm and 60Nm of peak torque at 5,200rpm.

According to the Japanese firm, the Mira e:S delivers a fuel economy of 30.0km/L (about 70.5mpg US) on Japan’s JC08 Mode test cycle, and 32km/L (approximately 75.2mpg US) on Japan’s 10-15 Mode test cycle.

Pricing of the Mira e:S in Japans starts just under 800,000 Yen (equal to US$10,450 or €6,651).
