Porsche’s Rennsport Reunion 7 event in California introduces a special automobile to celebrate the brand’s racing history. The incredible 911 GT3 R showcased is not street-legal, nor is it suitable for GT3 competition. This Porsche 911 GT3 R rennsport is simply extraordinary.

Porsche refers to this car as the 911 GT3 R rennsport, with a lowercase “R” – a stark contrast to the vehicle itself, which is anything but lowercase. Underneath its massive rear wing, requiring additional support braces due to the downforce it generates, lies a naturally aspirated 4.2-liter flat-six engine borrowed from the GT3 race car. However, this model is not built to GT3-class specifications and delivers an impressive 611 horsepower. The engine is optimized for E25 fuel and features custom pistons and camshafts. With a higher compression ratio and an astounding 9,400 RPM redline, one can only imagine the incredible sound it produces.
