Audi R18 e-tron quattro Review

Audi has unveiled the R18 e-tron quattro which have its racing debut on 20, 2014 in the six-hour race at

Due to the new LMP1 regulations that come into effect in Audi Sport factually every single component. The comes with a V6 TDI mid-engine powers the rear wheels and an quattro hybrid system at the axle (ERS-K – Energy System Kinetic, a system to kinetic energy).

Audi has optimized the flywheel energy system and worked on the hybrid with an electric turbocharger in the combustion engine (ERS-H – Recovery System Heat, a that stores energy from heat).

For the first wheel tethers are prescribed. connect the outer assemblies of the wheel suspensions with the and the ones of the rear suspensions the chassis structure. Another new is a CFRP (carbon fiber plastic) structure behind the – the so-called ‘crasher’ – which energy in a collision.

The updated R18 quattro will participate at the Le 24 Hours on June 14/15,

The next Audi R18 e-tron new technology for the World Champions

New race car from Audi for the season

Most efficient car ever built by Audi

Technical innovations with for production models

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

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

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

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

The basic elements of the Audi R18 quattro’s new configuration were back in 2012 and the design of all the components started at the end of 2012. The new sports car was rolled out in the early of 2013, followed by track of the most recent R18.

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

A developed V6 TDI mid-engine powers the wheels

e-tron quattro system at the front axle – Energy Recovery System a system to store kinetic

Optimized flywheel energy system

Hybrid system an electric turbocharger in the internal engine (ERS-H – Energy System Heat, a system stores energy converted heat)

New approaches to powertrain and energy management

Never has a race car been powered by as complex as the one used in Audi’s new sports car. The TDI engine, sets the benchmark in terms of remains a time-tested and important of the overall concept. The further V6 TDI unit of the Audi R18 e-tron makes a crucial contribution to the compliance with the energy of the regulations.

The new R18 has to do with up to 30 percent less than its immediate predecessor.

In to the internal combustion engine, the concept, for the first time, the integration of two hybrid systems. As in the a Motor-Generator-Unit (MGU), during events, recovers kinetic at the front axle, which into a flywheel energy system. For the first time, the of the internal combustion engine is to an electrical machine, which it possible to convert the thermal of the exhaust gas flow into energy – for instance when the pressure limit has been

This energy also into the flywheel energy system. When the car accelerates, the energy can either flow to the MGU at the front axle or to the innovative turbocharger, depending on the operating

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

Significantly changed for the aerodynamicists

New freedoms, accompanied by restrictions – this is how the new framework for aerodynamics can be put in a nutshell. A few examples: The 10 slimmer body of the new LMP1 car means that the front of the R18 mathematically smaller – which is an The bodywork accommodates slimmer which, in turn, reduces drag.

This is contrasted by other that do not provide any advantages in At 1,050 millimeters, the race car has to be 20 higher than before, and cockpit dimensions are prescribed as This leads to less aerodynamics. The lower overall of the car results in a slimmer underfloor. In it features a completely different in the area of the cutouts for the front

Consequently, the area that can downforce becomes smaller. respect to designing the front the engineers enjoy new freedoms. of a diffusor, a genuine front with a flap may be used for the time.

This promises advantages and lower costs, as part of the bodywork will itself to easier modification to the various race tracks. In the it was necessary to produce different assemblies.

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

improvement of safety

Even in the LMP1 sports cars their closed CFRP structure were regarded as one of the race car categories of all. Two accidents of the R18 at Le Mans in 2011 saw the drivers get off lightly. But this is no to stop.

The rule-makers have continued to the safety of the latest race car by imposing numerous discrete

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

For the time, wheel tethers are They connect the outer of the front wheel suspensions the monocoque and the ones of the rear with the chassis structure. of the two tethers required per wheel can forces of 90 KN – which equates to a force of nine metric

Another new feature is a CFRP behind the transmission – the so-called – which absorbs energy in a

This is another example of the challenges faced by the Audi as all these innovations increase in addition to the second hybrid Audi’s previous Le Mans weighed 915 kilograms. But in the future the weight may be reduced to 870 kilograms – means that Audi’s design technology reaches a new

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

International partners on board

The new R18 e-tron quattro will be on the together with strong in the 2014 season. For the first the Brazilian company Aethra Automotivos and the Swiss watchmaker support the title defense The two new partners complement Audi international portfolio in the sports car which includes Akrapovič, Bosch, Castrol, ITK Engineering, Michelin and OZ.
