With a combination of a TDI turbodiesel engine and an electric motor, Volkswagen has transformed an already-efficient hatchback into an absolute greenie. Being a full hybrid, the Golf  TDI Hybrid concept is capable of being run on either fuel or electricity independently, or together. A new seven-speed DSG dual-clutch gearbox and engine start/stop system eek every last bit of fuel savings out of this concept, resulting in claimed fuel economy of almost 70 mpg. Impressive stuff
