The Daihatsu Mira e:S (Japanese: ダイハツ・ミライース, Hepburn: Daihatsu Mira Īsu) is a kei car manufactured by the Japanese automaker Daihatsu as the successor to the original Mira. It was previewed by the "e:S" concept car at the 2009 Tokyo Motor Show. The car was introduced to the Japanese market in September 2011. It was also sold by Toyota as the Toyota Pixis Epoch (Japanese: トヨタ・ピクシスエポック, Hepburn: Toyota Pikushisu Epokku), which was released on 10 May 2012 and by Subaru as the Subaru Pleo Plus (Japanese: スバル・プレオプラス, Hepburn: Subaru Pureo Purasu), which was released on 21 December 2012.

In response to the recent rise in environmental awareness and low priced cars, the Mira e:S has been developed with the concept of "the third eco car". It is the mass production version of the "e:S" concept car.
The existing technology owned by Daihatsu was reviewed, and by using the "e:S technology", the fuel efficiency has been improved by 40% compared to the conventional engine by reducing the weight of the vehicle, improving the transmission, improving the engine, among others.[4]
The engine improves combustion efficiency by improving the compression ratio and the injector spray atomisation, etc., and by using the "i-EGR system", the mechanical loss is reduced to the utmost by making improvements over details. Furthermore, by adopting cooperative control by the electronic throttle, the most efficient state is maintained according to the driving situation. The CVT also reduces emissions by increasing the efficiency of the oil pump and improves the power transmission efficiency by lowering the CVT control pressure. As a result, the engine load was also reduced by optimising the transmission gear ratio (high gearing).[5]
The body is made streamlined while maintaining the safety and a comfortable ride. The weight reduction has been made to the interior parts such as thinning of resin parts such as instrument panels, seat frame and CVT for idling stop. The air resistance has been suppressed by improving the shape of the front corners and reducing the flow velocity under the floor, and the rolling resistance was also reduced by improving the aforementioned weight reduction, bearings and brakes.[5]
The "Eco Idle" idling stop mechanism that is installed in some grades of the Move and Move Conte is also equipped as standard for all vehicles, but the system in Mira e:S is the world's first for CVT vehicles with petrol engines. By applying the brakes and automatically stopping the engine when the speed is 7km/h (4.3mph) or less, the fuel consumption is improved by increasing the idling stop time. In addition, by reducing the number of dedicated parts, it has achieved weight reduction and "compactification".[5]
With these technologies, JC08 mode fuel consumption achieved a fuel consumption of 30km/L (85mpg‑imp; 71mpg‑US) for front-wheel drive models and 27km/L (76mpg‑imp; 64mpg‑US) for four-wheel drive models.[5]
The cost of the vehicle was reduced by reducing the number of parts and reducing the weight of the vehicle by approximately 60kg (132lb) by reviewing the component layout, shape, material selection and specifications.[5]
The Mira e:S is assembled at Daihatsu Motor Kyushu in Nakatsu, Ōita.
