Project PUMA - Segway meets car 

April 8, 2009 Straight out of left field, General Motors and electric scooter maker Segway have revealed a two-wheel, two-seater prototype vehicle they’ve code named Project P.U.M.A (Personal Urban Mobility and Accessibility). The self-balancing electric “car” is designed to transport two adults in a seated position, and can travel up to 25 and 35 miles (40 – 56 km) powered by large format lithium-ion batteries on as little as $0.60 worth of electricity.

The 300 lb (136 kg) zero-emissions vehicle has a top speed of 35 mph (56kph) and is powered by two electric wheel motors. The control system is based on the original Segway with dynamic balancing and drive-by-wire for acceleration, steering, and braking. It also features vehicle-to-vehicle communications, digital smart energy management and a dockable user interface that allows off-board connectivity.
