Porsche has raised the bar for wagons with its Panamera Sport Turismo concept. The conceptual wagon is a hybrid, sporting a supercharged 3.0-liter V6 engine producing 333hp and a 95hp electric motor. The Panamera Sport Turismo is designed to run off of electricity-its engine needs to be switched into hybrid mode-and has a max range of 18 miles, a 0 to 62 time (in hybrid mode) of less than six seconds and an all-electric top speed over 80 mph. The charging time for the plug-in Panamera is said to be 2.5 hours. Porsche, make this happen.
