Subaru's parent Fuji Heavy Industries has released a one-year schedule for development of a new electric car. In concert with Tokyo Electric Power Company (Tepco), FHI will develop and manufacture 10 prototype vehicles based on the Subaru R1e concept. Tepco will use the cars in its service fleet, while studying their performance and economic viability. Fuji had earlier touted a new type of lithium-ion battery it had developed, expected to last for 15 years or 150,000 miles. For that reason, the EVs will likely serve as a test bed for the battery, which the company wants to market to hybrid carmakers as well as launch its own, homegrown hybrids. Tepco, on the other hand, will use its R&D base in charging systems to develop a kit capable of charging the batteries to up to 80% capacity within 15 minutes. Check out the cars' specs after the jump.
