Porsche is no stranger in making what are already powerful sports cars, into something even faster, more agile, and lightweight. The 911 GT3 RS serves as another testament to Porsche's unending goal of building ever faster two-doors that are built solely for performance. Powering the GT3 RS is not a turbocharged flat-six. Instead it has a naturally-aspirated 4.0-liter engine that is mated to a seven-speed dual-clutch transmission. It can sprint from 0 - 100 km/h in 3.2 seconds and reach a top speed of 312 km/h.
