Audi designs lightest sports antecedent in the history

Design engineers – either in prolongation or competition automobile engineering – are tasked to solve aim conflicts on a daily basis. However, a judgment pattern of a new Audi R18 e-tron quattro confronted a engineers during Audi Sport with a quite severe requirement. On a one hand, a racing weight of a LMP1 cars compared to final year is authorised to diminution from 915 to 870 kilograms. 45 kilograms reduction weight make a poignant disproportion in racing. At a same time, a new technical regulations enclose several mandate that call for totally new solutions that lead to an boost in weight. For example, to strengthen a motorist in a box of parallel impacts, a regulations allot Zylon side panels. This quite tough and impact-resistant element prevents parallel intrusions of forked objects in a cockpit in an accident. The monocoque itself had to be redesigned as good to withstand a aloft exam loads specified starting in 2014.

The 8 circle tethers (two per wheel) that are to forestall a subdivision of a wheels from a automobile in box of a pile-up are new as well. Furthermore, a 2014 Audi R18 e-tron quattro is versed with a back pile-up interesting structure. This new member done of CO fiber reinforced cosmetic (CFRP) absorbs a appetite in a rear-end collision. And, final though not least, a regulations now concede transmissions with 7 instead of a prior 6 brazen gears. The new rigging span and a actuation make a disproportion on a beam as well. “The sum of all these measures corresponds to an additional weight of some-more than 20 kilograms,” explains Dr. Martin Mühlmeier, Head of Technology during Audi Sport.

As a result, a engineers were tasked to make a newly designed competition automobile even lighter than before – to recompense for this additional weight while achieving a reduce smallest weight. “Thanks to a consistent growth work there are no measures left that would produce vital weight assets in a singular step. Instead, a art lies in achieving serve improvements of all a details,” says Wolfgang Appel, Head of Vehicle Technology during Audi Sport. Audi has consistently increasing a CFRP calm in a competition car. In a 2014 season, a steering circle mainstay of a sports antecedent is done from this element for a initial time. However, this element continues to be taboo in several areas. For instance, a circle cessation elements still have to be done of lead materials, according to a regulations.

Due to these regulatory specifications and technical options a room for scheme becomes increasingly compelled year after year. In annoy of this, Audi achieved a aim weight in a R18 e-tron quattro for a stream season. The diesel hybrid sports automobile meets a extent of 870 kilograms.

In total, a new Audi R18 e-tron quattro is safer, lighter and some-more fit than any of a predecessors, and Audi’s light-weight record has a vital partial in this. For some-more than 20 years, a association has been proof a imagination in this area in a growth of a prolongation cars as well.
