Every component is a masterpiece

- During the 24 Hours of Le Mans, each spark plug in the 919’s engine ignited the fuel-air combination more than 5 million times. The two-litre, four-cylinder turbo engine runs at speeds up to 9,000rpm.
- Weighing barely 500g, this mirror unit is housed in a carbon-fibre composite shell. Mirrors must have a surface area of at least 100 sq cm, be able to show everything from 10 metres behind, and have a day and night mode.
- Spinning at more than 120,000rpm, the turbine inside the 919 Hybrid’s exhaust helps to charge under acceleration. Its variable turbine geometry allows it to recuperate energy even at low engine speeds and thus low exhaust pressures.
- With a fibre-composite-plastic and high-modulus carbon-fibre frame, and a polycarbonate panel, this door weighs just 3kg. It’s also part of a head-restraint structure, and can withstand 680kg of load, replicating an impact from the driver’s helmet.
- This little box is the brain of the Porsche’s 919 Hybrid Le Mans-winning car. The engine control and chassis control units use 3D track profiles, and every conceivable driving condition, to tweak everything in the drivetrain for the optimal lap.
- Any spilt fuel during a pitstop could instantly ignite if it came into contact with the hot race car, which is why the tank’s nozzle is a complex mechanism with moving parts, allowing air out and fuel in – using only gravity – as quickly as possible.
- Twenty-four buttons and switches on the front and six paddles on the back of the 919 Hybrid’s steering wheel control a plethora of settings and functions: brake balance, radio, water bottle, coasting, boost button, headlight flasher and more.
- Hundreds of liquid-cooled lithium-ion battery cell are what give the 919 its electric-powered whoompf. Each one is able to charge and discharge energy quickly, while also having a high storage capacity. In total, they provide the 919 with 800 volts.

Take a close-up look at some of the finest pieces of technology that went into this year’s Porsche 919 Hybrid

  • A123 batteries aren't german, the Staubli fuel nozzle is probably swiss, and the ECU is from Mclaren.

  • Maybe there's some non-German engineering in there too ? Like GKN's....
