Porsche demonstrated its commitment to hybrid technology with the 918 Spyder concept, a car that boasts outlandish specifications. The two-seater uses a plug-in hybrid system comprised of two electric motors coupled to a 3.4-liter V-8 racing engine. As a parallel hybrid, the car can run on pure electricity, just gas, or a combination of the two.
