Dubbed Project P.U.M.A. (Personal Urban Mobility and Accessibility), GM and Segway are developing an electrically powered, two-seat prototype vehicle that has only two wheels. It could allow people to travel around cities more quickly, safely, quietly and cleanly - and at a lower total cost. Cities around the world are actively looking for solutions to alleviate congestion and pollution. Project P.U.M.A. combines several technologies demonstrated by GM and Segway, including electric drive and batteries; dynamic stabilization (two-wheel balancing); all-electronic acceleration, steering and braking; vehicle-to-vehicle communications; and autonomous driving and parking.
