Flextreme

The McCar is a compact, two-door, four-seater with a built-in, folding three wheeled electric scooter. When docked, the scooter shares both its battery and motor to extend the all-electric range and power. Sheer genius … and a catchy name too

Vauxhall's Flextreme GT/E uses a small petrol engine to extend the electric range to more than 300 miles and active shape shifting to reduce the drag co-efficient to just 0.22.
