Audi Press Release
- New LMP1 race car receives sport approval
- Homologation process started in November
- 75-page documentation for the Audi R18 e-tron quattro
When the Audi Sport squad headed by Dr. Wolfgang Ullrich tackles the construction of a new race car, a challenging task has to be resolved. Maximum creativity is obviously a key aspect but at the same time, all the regulations must be complied with. The Technical Regulations for 2014-specification LMP1 sports cars encompass 20 chapters with 67 pages, divided into detailed sections and a comprehensive annex.
The so-called homologation sheet of the Audi R18 e-tron quattro has 75 pages – more than any of its predecessors. “The level of detailing is the reason,” explains Dr. Martin Mühlmeier, Head of Technology at Audi Sport. “The homologation documents put new emphasis on areas such as safety-relevant components, the powertrain and the energy systems.” The freedoms provided by the LMP regulations include the possibility to homologate various body versions. During the course of the season, additional variations in the sense of an evolution may be subjected to post-homologation. “In contrast, the class rating which specifies the permitted amount of hybrid energy, the operation principle of the hybrid system, the type of fuel used by the internal combustion engine and the output and consumption window may not be changed anymore,” says Dr. Mühlmeier. Audi relies on a hybrid system in which the kinetic energy is recuperated at the front axle and fed back into the system.
In Ingolstadt, the FIA and ACO experts subsequently performed further tests, for instance of individual functions of the race car, made measurements, checked individual geometries by means of gauges and inspected materials. Each R18 e-tron quattro car which Audi will be using in the FIA World Endurance Championship (WEC) this year has its own folder, which contains the homologation documents and the car’s chassis number. This description of the race car, which is like an ‘ID card’ in a manner of speaking, has to be presented at each document and technical scrutineering session at all events. Homologation is an important, but by no means the only prerequisite for fair and thrilling competition in the 2014 season.
