The Porsche 919 Hybrid is a Le Mans Prototype 1 (LMP1) sports car built and used by the German manufacturer Porsche in the 2014, 2015, 2016 and 2017 seasons of the FIA World Endurance Championship. It was Porsche's first all-new prototype since the RS Spyder and the first to compete in sports car racing's premier level since the Porsche 911 GT1. Work on the car began in mid-2011 and its monocoque was finalised at the end of 2012 with inspiration from the 911 GT3 R Hybrid racing car and the 918 Spyder hybrid-sports vehicle. The car features two separate energy recovery hybrid systems to recover thermal energy from exhaust gases and convert kinetic energy into electrical energy under braking for storage into lithium-ion battery packs. In accordance with the 2014 regulations, the vehicle was placed in the 6 MJ (1.7 kWh) class. Its engine, a 2 l (120 cu in) 90-degree angled mid-mounted, V4 mono turbocharged petrol power unit produced 500 hp (370 kW) and acted as a chassis load bearing member.
The 919 Hybrid project was discontinued after 2017 to allow Porsche to focus on entering Formula E and an evolution of the car called the 919 Evo was demonstrated in 2018.
Porsche revealed an evolution of the 919 Hybrid on 11 April 2018, as it broke the lap record of the Circuit de Spa-Francorchamps with a lap time of 1 minute and 41.77 seconds, with Jani behind the wheel. It was 0.783 seconds faster than the four-time World Champion Lewis Hamilton's qualification lap at the 2017 Belgian Grand Prix, previously posting a 1 minute and 42.553 seconds in a Formula One car, the Mercedes AMG F1 W08 EQ Power+. Jani was more than 12 seconds faster than the standard 919 Hybrid's 2017 pole position lap of 1 minute and 54.097 seconds. During the lap, Jani' recorded a speed trap at 359 km/h (223.1 mph) on the Kemmel Straight, with an average speed of 245.61 km/h (152.6 mph)
