Fuji Heavy Industries Ltd. (FHI), the maker of Subaru automobiles, launched its Subaru Plug-in STELLA electric vehicle (EV). The model will be sold in Japan directly through FHI, with delivery starting from late July. Around 170 units of delivery in total will be planned in this fiscal year (by the end of March 2010). After-sales services will be provided through some Subaru dealerships designated by FHI.
The production version of the STELLA EV features a more powerful traction motor than used in the prototype introduced last year: 47 kW and 170 N·m (125 lb-ft), compared to 40 kW and 150 N·m (11l lb-ft). A 9 kWh, 346V Li-ion battery pack comprising 16 modules in series supports a range of 90 km (56 miles) when driven in the Japan 10-15 mode cycle.

The EV can be re-charged up to 80% of its capacity in 15 minutes using the quick charging system (3-phase 200VAC, 50 kW); a full recharge takes 8 hours with 100VAC household power or 5 hours with 200VAC.
Fuji Heavy has been using Li-ion packs from Nissan-NEC joint venture AESC (Automotive Energy Supply Corporation), but is considering expanding its battery procurement sources to potentially include PEVE, the partnership between Toyota and Panasonic Corp. Toyota holds a 16.5% stake in Fuji Heavy. (Earlier post.)
The Subaru Plug-in STELLA was developed based on the Subaru STELLA mini car. It combines the EV system with the compact and light body, which offers an adequate and convenient means of transportation for daily commuting.
The manufacturer’s suggested retail price of the Subaru Plug-in STELLA is ¥4,725,000 (US$48,000), including consumption tax and without factoring in subsidies. It was approved by the “Next Generation Vehicle Promotion Center” as a vehicle whose users are offered a subsidy of ¥1,380,000 (US$14,000) at a maximum. Additional tax reduction will also be expected due to special measures conducted by Japanese Ministry of Land, Infrastructure, Transport and Tourism.
