Audi Press Release
- Audi R18 e-tron quattro represents multiple optimization of light-weight design
- Lower weight, higher safety and fuel economy: No Audi Le Mans prototype has ever been as efficient as this one
- New safety rules increase requirements
The eight wheel tethers (two per wheel) which are to prevent the separation of the wheels from the car in case of a crash are new as well. Furthermore, the 2014 Audi R18 e-tron quattro is equipped with a rear crash absorbing structure. This new component made of carbon fiber reinforced plastic (CFRP) absorbs the energy in a rear-end collision. And, last but not least, the regulations now allow transmissions with seven instead of the previous six forward gears. The new gear pair and its actuation make a difference on the scales as well. “The aggregate of all these measures corresponds to an additional weight of more than 20 kilograms,” explains Dr. Martin Mühlmeier, Head of Technology at Audi Sport.
Due to these regulatory specifications and technical options the room for maneuver becomes increasingly constrained year after year. In spite of this, Audi achieved its target weight in the R18 e-tron quattro for the current season. The diesel hybrid sports car meets the limit of 870 kilograms.
