The rollout of the LMP1 prototype took on June 12, 2013, just two years after the announcement of Porsche, again to compete in the 24 - hour race at Le Mans with a works team.
On 30 June 2011, the Porsche AG announced in 2014 to go for the first time with a works team at Le Mans. 16 years after the double victory of the Porsche 911 GT1 in the 24- hour race at Le Mans in 1998 they will compete for the first time with the new LMP1 again in the highest class and therefore also travel for the overall victory.

The monocoque of the vehicle is an enclosed structure of carbon with a honeycomb core of aluminum. In addition, it is reinforced at the sides by the installation of additional panels to ensure more safety in a side impact. Front and rear of the car has over independent suspension with struts and adjustable shock absorbers. The ventilated brake disc at the front and rear are made of carbon fiber, the calipers are produced from light metal.
Porsche is committed under these rules as factory team to compete with a hybrid vehicle. In 919 Hybrid, a turbocharged V4 petrol engine is used with two liters, which is supported by two energy recovery systems. The engine is made of aluminum and features direct injection and a dry sump lubrication. The engine management system has been developed by Robert Bosch GmbH, the power is transmitted through a sequential, hydraulically actuated transmission with seven forward gears.
In addition to the recovery of braking energy on the front wheels electrical energy is obtained via a motor driven by the exhaust gas flow generator, which is then stored in water-cooled lithium - ion batteries that have been developed in collaboration with the company A123 Systems. When accelerating, the energy is delivered to the front wheels so that the rear-wheel drive vehicle has otherwise a temporary -wheel drive. Per round so up to 8 megajoules of energy may be supplied.
The power of the internal combustion engine is provided with more than 370 kW ( 503 hp ), the power of the electric motor with more than 184 kW (250 hp).
The car rides on radial tires from Michelin, the wheels come from BBS and are forged from magnesium.
