Test Drive: The All-New Porsche 911 GT3 RS

The Porsche 911 GT3 RS has always been the pinnacle of road-legal track performance, and the latest generation raises the bar to staggering heights. Its 4.0-liter naturally aspirated flat-six screams to 9,000 RPM, producing 525 horsepower that's delivered with the precision of a surgical instrument. The DRS-inspired rear wing generates 409kg of downforce at 200km/h. On track at the Nürburgring Nordschleife, it feels less like a road car and more like a GT3 race car that happens to have license plates. This is Porsche at its obsessive, uncompromising best.
