Porsche 911 RSR

The Porsche 911 RSR and its predecessors the GT3 R, GT3 RS and GT3 RSR are a line of GT racing cars that Porsche produced for endurance racing, built on the 911 in the Motorsport Center at Weissach. The line began with the 996 GT3 R, created in 1999 and debuting at that year's 24 Hours of Le Mans, and passed through the 996 GT3 RSR, the 997 GT3 RSR and the 991 RSR. For 2017 Porsche presented a newly developed 911 RSR whose engine and transmission were reversed, turning the rear-engined 911 into a mid-engined racing car with a 4.0 litre flat six making around 375 kW. A 2019 development with 95 percent new parts followed, enlarged to 4.2 litres. Manthey Racing won the GTE Pro class at Le Mans in 2018, and the 996 versions won seven class victories at Le Mans by 2006.
