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 in 2010 and the first prototype run by the factory team since the Porsche LMP1-98. It utilises a 2.0 L four-cylinder turbocharged engine with a battery-based hybrid system.[2] The car made its competitive début at the 2014 6 Hours of Silverstone, the opening round of the 2014 season.

The 919 nomenclature is a reference to the successful Porsche 917 of the 1970s, and the Porsche 918 production sports car that the company débuted in 2013.[3]

Competition history[edit]

Development (2012—2013)[edit]

Porsche made an initial announcement of the new program on 11 June 2012,[4] with Timo Bernhard and Romain Dumas named as the initial development and race drivers of the car. Exactly one year after its announcement, the first test chassis completed its initial rollout.[5] The engine of the 919 utilizes a 2-litre V4 turbocharged gasoline engine with direct injection and two energy recuperation systems, with new signing, Australian Formula One driver Mark Webber, testing the car at Algarve in Portugal.[6][7] The first public showing of the car was on 14 December 2013.[3] The 919 uses a Lithium-ion battery hybrid system, and can store up to 8 MJ of energy per lap of Le Mans. The car will also have an exhaust-energy recovery system that runs through a turbine in the exhaust.[8]

Competition debut (2014)[edit]

The 919 Hybrid made its competitive debut at the 2014 6 Hours of Silverstone at the Silverstone Circuit. The #20 entry of Timo Bernhard, Brendon Hartley and Mark Webber finished third behind the two Toyota TS040 Hybrids, while the #14 entry of Romain Dumas, Neel Jani and Marc Lieb was forced out of the race after thirty laps.[9]

At the 2014 24 Hours of Le Mans, the #20 entry, driven by Mark Webber at the time, closed to within one minute of the leading #1 Audi R18 e-tron quattro with an hour and a half when the car suffered a broken anti-roll bar. Before the hour was out, Marc Lieb was forced to pit the #14 entry with the same issue. Car #14 returned to the circuit to complete a ceremonial lap at the end of the race and was classified eleventh overall, but car #20 was unable to take to the circuit and was not officially classified as finishing, despite having completed 90% of the winner's race distance.
