The Porsche 919 Hybrid is a sports-prototype racing car constructed by the German car manufacturer Porsche for use in the Le Mans Prototype 1-Hybrid (LMP1-H) category of the FIA World Endurance Championship for factory-supported hybrid-powered cars. It is the first sports-prototype built by Porsche since the RS Spyder, the first sports-prototype built by Porsche to compete in a top category of sportscar racing since the Porsche 911 GT1-98 and Porsche LMP1-98 and the first sports-prototype to be raced by Porsche as a racing team since the Porsche 911 GT1-98 and Porsche LMP1-98. It uses a 2.0 L four-cylinder turbocharged engine with a battery-based hybrid system. The car made its competitive debut at the 2014 6 Hours of Silverstone, the opening round of the 2014 season. The 919 Hybrid project is scheduled to be discontinued at the end of the 2017 season to allow Porsche to focus on entering Formula E.
