Honda Motor Co Ltd announced Sept 28, 2017, that it would partially remodel the "Step WGN" mid-size minivan and release it Sept 29, 2017.

This time, Honda added a hybrid model (HEV) of the "Spada" (a high-end model of the Step WGN).

The former (fifth-generation) Step WGN, which was released in April 2015 after fully remodeling the fourth-generation Step WGN, is equipped with a 1.5L direct-injection turbo engine, and no HEV model was available for it. Honda aimed to sell 5,000 units of the vehicle per month with only the direct-injection turbo engine model.

However, it turned out that the demand for HEVs was high in the Japanese market. Toyota Motor Corp's "Noah" and "Voxy" and Nissan Motor Co Ltd's "Serena," which compete with the Step WGN, offer HEVs (mild HEV in the case of the Serena). In the first half of 2017 (from January to June), the unit sales of the Step WGN was about 22,000, which is smaller than the initial plan. So, the Step WGN lagged behind its competitors in terms of unit sales.

In view of this, Honda added the HEV to the high-end model this time. It comes with the "i-MMD" two-motor hybrid system, which is used for "Odyssey" mid-size minivan, in the aim of catching up with the rivals.

The hybrid system is equipped with a 2.0L gasoline engine. The maximum output and maximum torque of the engine are 107kW and 175N·m, respectively. The maximum output and maximum torque of the driving motor are 135kW and 315N·m. They are the same as those of the Odyssey's system.

The fuel efficiency of the vehicle is 25.0km/L (approx 58.8mpg) under the JC08 test mode and 20.0km/L under the WLTC test mode. The WLTC fuel efficiency, which was obtained for Honda's car for the first time, can be broken down into 18.8km/L in urban areas, 21.8km/L in suburban areas and 19.5km/L on expressways.
