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 that raced until 2010, the first sports-prototype built by Porsche to compete in a top category of sportscar racing since the 1998 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.[2] 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.[3]

The 919 nomenclature is a reference to the successful Porsche 917 race car of the 1970s, and the Porsche 918 street car that debuted in 2013.[4]

Competition history[edit]

Development (2012–13)[edit]

Porsche made an initial announcement of the new program on 11 June 2012,[5] 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.[6] 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.[7][8] The first public showing of the car was on 14 December 2013.[4] The 919 uses a Lithium-ion battery hybrid system, and can store up to 6 MJ of energy (1.7 kWh) per lap of Le Mans. The car will also have an exhaust-energy recovery system that runs through a turbine in the exhaust.[9]

Competition debut (2014)[edit]

The 919 Hybrid made its competitive debut at the 2014 6 Hours of Silverstone at the Silverstone Circuit. The No. 20 entry of Timo Bernhard, Brendon Hartley and Mark Webber finished third behind the two Toyota TS040 Hybrids, while the No. 14 entry of Romain Dumas, Neel Jani and Marc Lieb was forced out of the race after thirty laps.[10]

At the 2014 24 Hours of Le Mans, the No. 20 entry, driven by Mark Webber at the time, closed to within one minute of the leading No. 1 Audi R18 e-tron quattro with an hour and a half of the race remaining when the car suffered a broken anti-roll bar. Before the hour was out, Marc Lieb was forced to pit the No. 14 entry with the same issue. Car No. 14 returned to the circuit to complete a ceremonial lap at the end of the race and was classified eleventh overall, but car No. 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.

Second season (2015)[edit]

The 919 Hybrid is a new car for its second season with approximately 85%–90% new parts while finally bringing the car's empty weight (no driver, no fuel) to the 870 kg minimum;[11] it has also moved from the 6MJ subclass to the 8MJ subclass. Porsche have stated that they will be able to fully use this extra battery capacity for Circuit de la Sarthe although it might struggle on shorter circuits.[12] The 919 achieved pole positions in Spa and Silverstone before finally picking up a pole and win at the 24 Hours of Le Mans. After Le Mans it won the five remaining races of the season.

Porsche 919 Evo[edit]

Porsche revealed an evolution of the 919 Hybrid on 11 April 2018, as it broke the lap record in Circuit de Spa-Francorchamps with a lap time of 1:41.77, with Neel Jani behind the wheel. The lap time was 0.783 seconds faster than Lewis Hamilton's flying qualification lap in 2017, previously posting a 1:42.553 in his Mercedes AMG F1 W08, a Formula One car. Jani was also over 12 seconds faster than the standard 919 Hybrid's 2017 pole position lap time of 1:54.097. During the lap, Jani's speed trap was 359 km/h (223.1 mph) at the Kemmel Straight, with an average speed of 245.61 km/h (152.6 mph).[13][14][15]

The V4 engine is retained for the Evo, putting out 720 PS (530 kW; 710 hp) without fuel flow restrictions. As the amount of recovered energy that could be used was increased from 6.37 megajoule for Spa to 8.49 megajoule, the output of the electric motors was increased from 400 PS to 440 PS (324 kW; 434 hp). The car's weight was reduced by 39 kg, now weighing in at 849 kg (1,872 lb) dry and 888 kg (1,958 lb) with driver ballast. Extensive aerodynamic upgrades were also added to the 919 Evo, resulting in a 53% increase in downforce and 66% increase in aerodynamic efficiency compared to 2017 WEC Spa qualifying spec.[14][16][15]

The 919 Evo will be doing demo runs through 2018 as part of the "919 Tribute Tour" at the Nürburgring Nordschleife for the 24 Hours Nürburgring, at the Goodwood Festival of Speed, for the Festival of Porsche at Brands Hatch and at Laguna Seca as part of Porsche Rennsport Reunion VI.[14][15]

On 29 June 2018 Porsche ran the 919 Evo on the Nürburgring and Timo Bernhard put down a time of 5:19.546, breaking the long-held record of 6:11.13 set by Stefan Bellof in the Porsche 956.[17]
