Porsche used the 2010 Geneva auto show to pull the cover off the hybrid 918 Spyder. Similar to current hybrids, it gets driven by its two electric motors, its 3.4-liter V-8, or a combination of the two. Under electric power, it has a range of about 16 miles, and Porsche boasts fuel economy of 78 mpg. Unlike most concepts, Porsche is seriously looking into production of the 918 Spyder.
