Porsche 911 GT3 R Hybrid 2.0 at the 24 Hours of Nurburgring

For many years there has been discussion about the real usefulness of motorsport technology to the applications to transfer, then in mass production. For some time, the situation seems to have reversed. The progressive development of new technologies, in fact, part of the interests Street and moved to the models used in the race.

It 's the case of the Porsche 911 GT3 R Hybrid Version 2.0, petrol / electric version, announced in December 2009 and shown in the official preview at the Geneva Motor Show 2010. The latest version (in time) of the hybrid Zuffenhausen, traveling as a laboratory built to contain fuel consumption and emissions (all with an eye to performance) had, in fact, done their baptism of the runway at the 24 Hours Nurburgring, test-bed for many years the most technologically innovative models.

Suffice it to recall the Volkswagen Scirocco natural gas that took part in the famous 24 Hours in 2009. The strand on which technology moves, the 911 GT3 R Hybrid is the same. The evolution of the 2011 GT "eco friendly" in Zuffenhausen, it will be deployed at the start of the Nordschleife of the marathon, scheduled for the weekend of June 26.

The car, built on the basis of specimens prepared for the 24 hours that it ran in May 2010, has the same goals for the team official: "We have focused emphasis on increasing efficiency - reveals Hartmut Kristen, head of Porsche Motorsport - This means that we intend to maintain the same performance of the 911 lap Hybrid version in 2010, but with less energy use and, consequently, lower consumption.

It will be our goal to produce models road hybrid, which will retain the characteristics of sportiness typical of our brand. " From the technological point of view, in fact, the new Porsche 911 GT3 R Hybrid differs from the previous higher power of the two electric motors. The car, which is fitted to the rear with the classic flat six (six-cylinder boxer) from 4 liters and 480 hp, is fitted with two power units for the front: a motor for each front wheel.

The total power of the two electric motors is 201 hp, which is some 40 hp more compared to the 911 Hybrid last year. In addition, the car looks overall a little 'lighter: 1300 kg, compared to the 1350 edition, 2010. One detail that differentiates the Version 2.0 is the current view of the hybrid power system for electric motors, a flywheel system (instead of the most widely used battery), placed in the cockpit, in a security cell in carbon side of the driver's seat.

This device is also capable of producing electricity from the kinetic energy stored during braking. In this way, the pilot will be available for a "power injection" particularly useful when overtaking or brawl on the track. It is, in essence, used the KERS in F1. Some changes of detail regarding the layout of controls, which for the most part have been moved on the wheel.
