The Evo version of the 919 Hybrid is based on the Le Mans overall winner vehicle and WEC World Endurance Champion of 2015, 2016 and 2017. It was released from some rule restrictions and its hybrid powertrain produces a system power of 1160HP. The Evo weighs a mere 849 kilograms and its modified, now active, aerodynamics generate over 50 percent more drive than the WEC model. Top speed during its record-breaking outing at Nürburgring-Nordschleife was 369.4 km/h.
The latest episode of the Porsche Top 5 series presents the five most important features of the 919 Evo.
