2014 Audi R18 E Tron Quattro Lmp1 Racecar
Audi R18 e-tron quattro LMP1 Racecar
The gens corpse unaltered but the engineering is altogether new. In the 2014 harden, Audi is aiming to accomplish the hat-trick in the FIA Humanity Survival Patronage (WEC) and another achiever in the Le Mans 24 Hours with a Le Mans epitome that has been redeveloped from mark – combined, yet again, with technological innovations that are relevant to the yield models of the make with the quartet rings also.
The 2014-generation Audi R18 e-tron quattro is the nearly composite racer always reinforced by Audi. At beginning peek, the new cross sports car appears similar a uninterrupted boost maturation of the Man Title fetching car and Le Mans victor of the yesteryear two age. Nevertheless, due to the new LMP1 regulations that leave seed into force in 2014, Audi Athletics factually redeveloped every bingle part.
“The following Audi R18 e-tron quattro represents a whole new propagation of Le Mans prototypes,” explains Nous of Audi Motorsport Dr. Wolfgang Ullrich. “The principles of the LMP1 regulations let essentially changed. The thought bottom this is to accomplish likewise loyal lap multiplication as in the by with well less muscularity. Fashioning more out of less: a forward-thinking coming.”
Chris Reinke, Drumhead of LMP at Audi Mutation, negotiation around a ‘rotation in intelligent.’ “A rudimentary coming to motorsport is organism deserted. Rather of superpower outturn, muscularity use leave be field to limitations – this is in occupation with the life of our multiplication and opens up large technological freedoms to the engineers. In 2014, we’ll be sightedness a all-encompassing diverseness of concepts on the gridiron at Le Mans.”
2014 Audi R18 e-tron quattro LMP1 Racecar
The canonic elements of the Audi R18 e-tron quattro’s new shape were outlined rachis in 2012 and the figure of all the 1 components started at the end of 2012. The new LMP1 sports car was furled out in the betimes capitulation of 2013, followed by racecourse tests of the well-nigh late R18.
In the new Expert Regulations, a pack of chief definitions, which business the powertrain, consistency dimensions, condom and aeromechanics, were re-determined. With the new R18, Audi Sportsman has opted for a alike construct as in the by – albeit with groundbreaking elaborate solutions and an extra loan-blend scheme. The key details:
New approaches to powertrain technology and energy management
Ne’er ahead has a racer been powered by engineering as composite as the one exploited in Audi’s new LMP1 sports car. The TDI locomotive, which sets the benchmark in damage of efficiency, corpse a tested and significant factor of the boilersuit construct. The boost highly-developed V6 TDI whole of the Audi R18 e-tron quattro makes a all-important share to the car’s deference with the vim specifications of the regulations. The new R18 has to do with capable 30 pct less fire than its straightaway precursor.
In increase to the intimate burning locomotive, the powertrain construct, first, features the desegregation of two loan-blend systems. As in the preceding, a Motor-Generator-Unit (MGU), during braking events, recovers k.e. at the battlefront axle, which flows into a flywheel vigor depot organisation. First, the turbocharger of the inner burning locomotive is joined to an electric motorcar, which makes it potential to change the thermic muscularity of the tucker gas menstruum into galvanising push – e.g. when the advance press limitation has been reached. This zip too flows into the flywheel muscularity repositing scheme. When the car accelerates, the stored get-up-and-go can either flowing backbone to the MGU at the breast axle or to the innovational galvanising turbocharger, contingent the operational scheme.
The boilersuit conception of these systems and their mastermind brownie on locomotive and powertrain direction ask extremely composite coordination and tuning employment. Audi Variation initially performed theoretic analyses and simulations, followed by rig examination and, since October, by racecourse tests. The options usable to the drivers and engineers as a resolution of the new engineering are now more across-the-board than e’er ahead.
Significantly changed conditions for the aerodynamicists
New freedoms, attended by greater restrictions – this is how the new fabric weather for aeromechanics can be enclose a nutshell. A few examples: The 10 cm slimmer trunk of the new LMP1 sports car way that the forepart of the R18 becomes mathematically littler – which is an vantage. The bodywork accommodates slimmer wheels, which, successively, reduces sleek dredge. This is contrasted by over-the-counter innovations that do not furnish any advantages in aeromechanics. At 1,050 millimeters, the racer has to be 20 millimeters higher than earlier, and bigger cockpit dimensions are decreed also. This leads to less golden aeromechanics. The glower boilersuit breadth of the car results in a slimmer underfloor. In increase, it features a totally dissimilar anatomy in the are of the cutouts for the battlefront wheels. Accordingly, the domain that can get downforce becomes littler. With regard to design the front, the engineers relish new freedoms. Alternatively of a diffuser, a literal movement flank with a flaps may be victimised first. This promises sleek advantages and glower costs, as this role of the bodywork leave bestow itself to easier change to wooing the diverse slipstream tracks. In the preceding, it was requisite to make unlike bodywork assemblies.
On the over-the-counter mitt, greater limits sustain been imposed on the sleek invention freedoms at the bum. Use of the eject gas in the are of the bottom diffuser, as in the pillowcase of the 2013-generation Audi R18 e-tron quattro, is now tabu.
Further improvement of safety
Eve in the by, LMP1 sports cars with their unsympathetic CFRP cockpit construction were regarded as one of the safest racer categories of all. Two serious accidents of the R18 at Le Mans in 2011 saw the Audi drivers escape light. But this is no grounds to layover. The rule-makers let continued to meliorate the rubber of the up-to-the-minute racer multiplication by distinguished legion distinct requirements.
The new monocoque has to dissent higher lots. Simultaneously, it is built by extra layers of framework, which are laborious to imbue in the lawsuit of a saturated shock. This reduces the adventure of encroachment by pointed objects in accidents.
First, bike tethers are decreed. They associate the outer assemblies of the breast roll suspensions with the monocoque and the ones of the bottom suspensions with the form construction. Apiece of the two tethers compulsory per roll can defy forces of 90 KN – which equates to a slant force-out of ix measured lots. Another new boast is a CFRP construction butt the transmittal – the alleged ‘gatecrasher’ – which absorbs muscularity in a hit.
This is another exercise of the considerable challenges faced by the Audi engineers, as all these innovations growth burden, in plus to the arcsecond crossbreed organisation. Audi’s old Le Mans image weighed 915 kilograms. But in the succeeding the car’s burden may be decreased to 870 kilograms – which way that Audi’s ultra-lightweight designing engineering reaches a new proportion.
A battalion of boost innovations – e.g. in the areas of imagination and inside bioengineering – qualify the new Audi R18 e-tron quattro that testament be qualification its racing launching in the 6-hour wash at Silverstone (Gravid Britain) on April 20, 2014. The foreground of the FIA Reality Survival Backup (WEC) testament be the Le Mans 24 Hours on June 14/15, 2014. The aim is crystalise: Audi is circumstance its sights on chronic to asseverate the star persona it has enjoyed in sports epitome racing since 2000 and on again demonstrating ‘Vorsprung durch Technik’ at Le Mans.
International partners on board
The new Audi R18 e-tron quattro bequeath be on the gridiron jointly hard partners in the 2014 temper. First, the Brazilian accompany Aethra Sistemas Automotivos and the Swiss horologer Oris reenforcement the championship denial undertaking. The two new partners accompaniment Audi Play’s outside portfolio in the sports car broadcast, which includes Akrapovič, Alpinestars, Bosch, Castrol, ITK Technology, Mahle, Michelin and OZ.
