The small vehicle (only 3 m long, 1.70 m tall and 1.55 m wide, with a wheelbase of 1.98 m) is a 2+1 automobile that runs solely on electricity. Its lithium-ion batteries give it a range of 125 km on a single charge, with a top speed of 120 km/h, enough for most roads all over the world. Anyway, Nuvu would be a city car, only, if it went into mass production. Some say it will inspire Micra's next generation, but we will have to wait to confirm.
Nissan intends to produce and sell an electric vehicle by next year's Tokyo Motor Show, but appparently Nuvu has nothing to do with it apart from its drivetrain and batteries. The production-ready vehicle tends to be more conventional.
