4. Porsche 911 R
The Porsche 911 R had been rumored for some time, and it finally made its debut in Geneva. This model takes all that makes the 911 GT3 RS—namely its 4.0-liter flat-six with 500 horsepower and its upgraded suspension bits—and combines them with a lightweight and toned-down body. Unlike its GT3 RS relative, the R comes with a do-it-yourself six-speed manual gearbox. The end result is a 3.7-second 0-to-60 time and a 200 mph top speed.
