According to a report on Auto Express, Volkswagen plans to debut a new eco-friendly concept at the Frankfurt Motor Show in September that could potentially rival the Chevy Volt-based Opel Ampera in Europe. Unlike the automaker's previous green concepts like the hybrid Golf TwinDrive and diesel-powered BlueSport Roadster, the new and as-yet unnamed concept will be fully electric.
Beyond that, details are scarce. There's some speculation that the new EV may be based on the Volkswagen's New Small Family architecture that underpins the tiny Up! city car concept first seen way back in 2007, but that's not yet confirmed. In any case, the Frankfurt-bound electric vehicle is likely to use lithium ion batteries supplied by Toshiba.
