Ya ha salido la nueva normativa, en la que cambia radicalmente el concepto. Pasa de una normativa de motores a una normativa de consumo, pudiendose utilizar cualquier cosa (por motor) con tal de no pasar de X consumo en una vuelta.
Si es de gasolina: 4.8L por vuelta
Si es diesel: 3.93L por vuelta

Analizando el total de combustible consumido no, para evitar que los coches puedan ir a cuchillo cuando lo necesiten y a punta de gas cuando esté la carrera hecha. Supongo que lo harán mediante sensores, vuelta a vuelta.

No se, puede que si, pero creo que 2014 va a ser el año de la incertidumbre ya que los cambios son muy muy importantes. Creo que 2015 si que va a ser un pedazo de año, porque si ven que está bien hecho la normativa de 2014, se apuntarán mas, y entonces si que veremos mucha rivalidad :D

La verdad es que resulta curioso que Porsche y Audi puedan competir entre si, siendo ambos del mismo grupo...

El LMP1?
Se supone que podremos ver motorizaciones de todos los tipos, siempre y cuando se ajusten al consumo olbigatorio


En la retransmisión española por Europort comentaron que aparte de Audi, Toyota y Porsche, se uniria a las filas Nissan, y no hablaban del garaje 56. Claro que tampoco especificaron nada, igual solo entra como motorista, o igual se confundió, aunque el que hablaba parecia uno de los responsables de competición de Nissan en España

Efectivamente parece que se confirma de lo Webber como piloto de Porsche, algo que se rumoreaba hace tiempo, y con respecto al motor del Porsche LMP1, exacto todo parece indicar que es probable que sea un 4 cilindros, pero no solo en Porsche seguramente en casi todos sus rivales, aunque habrá que esperar a la confirmación.

Audi acaba de presentar su nuevo LMP1, evolución (estetica) del modelo de este año
Es un poco mas pequeño, pero mas alto.
Estos son los detalles mas importantes:
- A further developed V6 TDI mid-engine powers the rear wheels
- e-tron quattro hybrid system at the front axle (ERS-K – Energy Recovery System Kinetic, a system to store kinetic energy)
- Optimized flywheel energy storage system
- Hybrid system with an electric turbocharger in the internal combustion engine (ERS-H – Energy Recovery System Heat, a system that stores energy converted from heat)

nota de prensa, en inglés
Audi’s new LMP1 race car
Ingolstadt, 2013-12-12
The next Audi R18 e-tron quattro: new technology for the World Champions

The name remains unchanged but the technology is completely new. In the 2014 season, Audi is aiming to achieve a hat-trick in the FIA World Endurance Championship (WEC) and further success in the Le Mans 24 Hours with a Le Mans prototype that has been redeveloped from scratch – combined, yet again, with technical innovations that are relevant as well to the production models of the brand with the four rings.

The 2014-generation Audi R18 e-tron quattro is the most complex race car ever built by Audi. At first glance, the new hybrid sports car appears like a continuous further development of the World Championship winning car and Le Mans winner of the past two years. However, due to the new LMP1 regulations that will come into effect in 2014, Audi Sport has actually redeveloped every single component.

“The next Audi R18 e-tron quattro represents a completely new generation of Le Mans prototypes,” explains Head of Audi Motorsport Dr. Wolfgang Ullrich. “The principles of the LMP1 regulations have fundamentally changed. The idea behind this is to achieve similarly fast lap times as in the past with considerably less energy. Making more out of less: a forward-thinking approach.”

Chris Reinke, Head of LMP at Audi Sport, talks about a ‘revolution in thinking’. “A fundamental approach to motorsport is being abandoned. Instead of power output, energy consumption will be subject to limitations – this is in line with the spirit of our times and opens up great technical freedom to the engineers. In 2014, we’ll be seeing a wide variety of concepts on the grid at Le Mans.”

The basic elements of the Audi R18 e-tron quattro’s new configuration were defined back in 2012 and the design of all the single components started at the end of 2012. The new LMP1 sports car was rolled out in the fall of 2013 followed by track tests of the most recent R18.

In the new Technical Regulations, a large number of principal definitions, which concern the powertrain, body dimensions, safety and aerodynamics, were re-determined. With the new R18, Audi Sport has opted for a similar concept as in the past – albeit with innovative detailed solutions and an additional hybrid system. The key details:

- A further developed V6 TDI mid-engine powers the rear wheels
- e-tron quattro hybrid system at the front axle (ERS-K – Energy Recovery System Kinetic, a system to store kinetic energy)
- Optimized flywheel energy storage system
- Hybrid system with an electric turbocharger in the internal combustion engine (ERS-H – Energy Recovery System Heat, a system that stores energy converted from heat)

New approaches to powertrain technology and energy management
Never before has a race car been powered by technology as complex as the one used in Audi’s new LMP1 sports car. The TDI engine, which sets the benchmark in terms of efficiency, remains a time-tested and important element of the overall concept. The further developed V6 TDI unit of the Audi R18 e-tron quattro makes a crucial contribution to the car’s compliance with the energy specifications of the regulations. The new R18 has to do with up to 30 percent less fuel than its immediate predecessor.

In addition to the internal combustion engine, the powertrain concept for the first time, features the integration of two hybrid systems. As in the past, a Motor-Generator-Unit (MGU) during braking, recovers kinetic energy at the front axle which flows into a flywheel energy storage system. For the first time, the turbocharger of the internal combustion engine is linked to an electrical machine which makes it possible to convert the thermal energy of the exhaust gas flow into electric energy – for instance when the boost pressure limit has been reached. This energy also flows into the flywheel energy storage system. When the car accelerates, the stored energy can either flow back to the MGU at the front axle or to the innovative electric turbocharger, depending on the operating strategy.

The overall design of these systems and their direct impact on engine and powertrain management require highly complex coordination and tuning work. Audi Sport initially performed theoretical analyses and simulations followed by rig testing and, since October, by track tests. The options available to the drivers and engineers as a result of the new technology are now more extensive than ever before.

Significantly changed conditions for the aerodynamicists
New freedoms, accompanied by greater restrictions – this is how the new framework conditions for aerodynamics can be put in a nutshell. Some examples: The 10 centimeter narrower body of the new LMP1 sports car means that the front of the R18 becomes mathematically smaller – which is an advantage. The bodywork accommodates slimmer wheels, which, in turn, reduces aerodynamic drag. This is contrasted by other innovations that do not provide any advantages in aerodynamics. At 1,050 millimeters, the race car has to be 20 millimeters higher than before and larger cockpit dimensions are prescribed as well. This leads to less favorable aerodynamics. The lower overall width of the car results in a slimmer underfloor. In addition, it features a completely different shape in the area of the cutouts for the front wheels. Consequently, the area that can produce downforce becomes smaller.

With respect to designing the front end, the engineers enjoy new freedoms. Instead of a diffusor, a genuine front wing with a flap may be used for the first time. This promises aerodynamic advantages and lower costs, as this part of the bodywork will lend itself to easier modification to suit the various race tracks. In the past, it was necessary to produce different bodywork assemblies.

On the other hand, greater limits have been imposed on the aerodynamic design freedoms at the rear end. Use of the exhaust gas in the area of the rear diffusor, as in the case of the 2013-generation Audi R18 e-tron quattro, is now prohibited.

Further improvement of safety
Even in the past, LMP1 sports cars with their closed CFRP cockpit structure were regarded as one of the safest race car categories of all. Two severe accidents of the R18 at Le Mans in 2011 saw the Audi drivers get off lightly. But this is no reason to stop. The rule-makers have continued to improve the safety of the latest race car generation by imposing numerous discrete requirements.

The new monocoque has to resist higher loads. At the same time, it is reinforced by additional layers of fabric that are hard to penetrate in the case of a concentrated impact. This reduces the risk of intrusion by pointed objects in accidents.

For the first time, wheel tethers are prescribed. They connect the outer assemblies of the front wheel suspension with the monocoque and the ones of the rear suspension with the chassis structure. Each of the two tethers required per wheel can withstand forces of 90 KN – which equates to a weight force of nine metric tons. Another new feature is a CFRP structure behind the transmission – the so-called ‘crasher’ – which absorbs energy in a collision.

This is another example of the considerable challenges faced by the Audi engineers, as all these innovations increase weight, in addition to the second hybrid system. Audi’s previous Le Mans prototype weighed 915 kilograms. But in the future the car’s weight may be reduced to 870 kilogram – which means that Audi’s ultra-lightweight design technology reaches a new dimension.

A large number of further innovations – for instance in the areas of vision and interior ergonomics – characterize the new Audi R18 e-tron quattro that will be making its racing debut in the 6-hour race at Silverstone (Great Britain) on April 20, 2014. The highlight of the FIA World Endurance Championship (WEC) will be the Le Mans 24 Hours on June 14/15, 2014. The aim is clear: Audi is setting its sights on continuing to maintain the leading role it has enjoyed in sports prototype racing since 2000 and on again demonstrating ‘Vorsprung durch Technik’ at Le Mans.

International partners on board
The new Audi R18 e-tron quattro will be on the grid together with strong partners in the 2014 season. For the first time, the Brazilian company Aethra Sistemas Automotivos and the Swiss watchmaker Oris support the title defense project. The two new partners complement Audi Sport’s international portfolio in the sports car program, which includes Akrapovič, Alpinestars, Bosch, Castrol, ITK Engineering, Mahle, Michelin and OZ.
