Just before 24 Hours of Nürburgring, which begin on May 12, Porsche presents a legendary duo before 200.000 viewers who are scheduled to attend the most important event in German motorsport: Timo Bernhard y Hans-Joachim Stuck they will get behind the wheel of Porsche 919 Hybrid Evo and Porsche 956 C., respectively, for a demonstration on the famous layout of the Nordschleife.
The 919 Hybrid, the winning car of Le Mans and the FIA World Endurance Championship in 2015, 2016 and 2017, will meet the vehicle that won all the titles in the World Championship of Sport Prototypes from 1982 to 1984 and that still holds the absolute record on the Nordschleife track.
This display marks the first public appearance of the 919 Hybrid Evo. With this car, which has been released from the restrictions imposed by the championship regulations, Porsche has recently set a new record at Spa-Francorchamps.
On April 9, 2018, the official driver Neel Jani (Switzerland) covered the 7.004 kilometers of the Belgian track in 1m41s770 seconds. With that record he broke in 783/1000 the previous record set in 2017 by Lewis Hamilton at the wheel of a Mercedes F1 W07 Hybrid.
However, at the second stop of the "Tribute Tour to 919" that will take place on the Nordschleife, no timers will be used, because the two racing cars will be behind a safety car and will skip the start and finish lines due to the grid formation for the 24-hour event.
The 956 C that Stuck will use has chassis number 005. It's the car they shared. Jacky Ickx y Jochen Mass throughout the 1984 World Championship. For commercial rights reasons, the name of the sponsor, the tobacco company Rothmans, has had to be replaced by the word Racing.
On May 28, 1983, during practice for the 1.000-kilometer race, Stefan Bellof made an impressive lap of the Nordschleife in 6: 11,13 minutes at more than 200 km / h on average. The 2.649cc, six-cylinder twin-turbo boxer engine in the 956 C produced 620 horsepower.
Like the 956, the Porsche 919 Hybrid has been the most innovative racing car of its time. The class 1 Le Mans prototype, which has participated successfully in the FIA WEC from 2014 to the end of 2017, is powered by a compact two-liter turbo V4 engine and by two different energy recovery systems. One transforms the energy from braking the front axle into electricity.
The second system generates electrical energy from the exhaust, where the gases accelerate a turbine to 130.000 revolutions per minute. The electrical energy is temporarily stored in a liquid-cooled lithium-ion battery. The combustion engine transmits power to the rear axle, while electric motors drive the front axle to accelerate the four-wheel-drive car, while again recovering energy from the exhaust system.
To set the 919 Evo for the record, the base has been the 2017 World Championship winning car. All undercarriage hardware remains unchanged. The improvements came from the developments that were prepared for the WEC 2018, but that were never run with them due to the retirement of the team, at the end of 2017. Additionally, several aerodynamic modifications were made.
Without a doubt, it will be a good opportunity to see two great race cars on the most impressive circuit in the world.
