Luxury Electric Cars

Electric power energizes the new Porsche 918 Spyder in five ways, starting with an electric-only mode with an 18-mile range and ending with a “hot-lap” mode that combines the power of the electric motors with a V-8 combustion engine for a maximum speed of 214 miles per hour. That means you can go from zero to 60 miles per hour before you can count to three. Only 918 Spyders will be built. $845,000; porsche.com.
