TCC’s Bottom Line
The 2015 BMW i8 is a ground-breaking new sports coupe with a plug-in hybrid powertrain that delivers several driving personalities from which the driver can choose. The 2015 Porsche 918 Spyder delivers unheralded levels of both performance and efficiency in a supercar. Now in its third year, the 2014 Tesla Model S has no direct competitor. It remains the undisputed top choice in the growing world of plug-in electric cars, and there's a good case to be made that it's the most advanced car of any kind on the planet.
