Spied: 2014 Porsche 918

What It Is: Porsche’s new supercar, the 2014 918, which will be launched as a Spyder with a removable top and as a hybrid only. Later, a coupe body and racing versions could be added. Why It Matters: This car is the spiritual successor of the 959 of the 1980s and the nearly decade-old but not forgotten Carrera GT. The 918 model designation also evokes memories of the infamous 917 race car.
