Subaru's small electric car, the two-passenger R1e donated its electric powertrain to the Japanese automaker's newest gasoline-free concept car, the Plug-in Stella Concept. Unveiled today at the G8 Hokkaido Toyako Summit in Japan, the Plug-in Stella will help Subaru develop electric vehicles for public consumption.

Five examples of the five-door tall wagon will be built for testing in Japan. Like the R1e, the new car was developed by Subaru in conjunction with Tokyo Electric Power. The Plug-in Stella Concept has a four-passenger capacity and will travel up to 50 miles on a full charge. Top speed is 50 mph thanks to the car's 54 horsepower electric motor that develops 110 lb-ft of torque instantaneously. The car stores energy in a lithium ion battery pack. The quick-charging battery can be topped up to 80 percent of full capacity in just 15 minutes but, curiously, a full charge takes eight hours.
