Audi R18 e-tron quattro Specifications

The Audi R18 e-tron quattro is the first Audi race car that no longer accelerates exclusively by an internal combustion engine. In the case of the R18 e-tron quattro, Vorsprung durch Technik means the development of an independent hybrid system.

As in other areas, Audi Sport also cooperates with external manufacturers in the production of components for the hybrid system. The development partner for the accumulator is Williams WHP, for the Motor Generator Unit (MGU) the long-standing technology partner Bosch.

The system, which Audi integrated into the front axle, consists of two drive shafts, the Motor Generator Unit including planetary gears, an electronic flywheel accumulator, an insulation monitoring unit for high-voltage safety and the control system.


The process of energy recovery is relatively simple to explain, but the technical implementation is extremely demanding. Energy recovery takes place during braking. In this process, the wheels drive the MGU. The FIA regulations define the permissible braking zones.

The Motor Generator Unit electrically accelerates a carbon fiber flywheel running in high vacuum. When the driver accelerates again after corners, the system releases the energy to the front axle from a speed of 120 km/h. The system is then switched off. The regulations allow transferring 500 kJ of energy to the front wheels between two braking phases. The planetary gearbox adjusts the transmission ratio during acceleration and braking. The e-tron quattro synchronizes, the two independently driven axles exclusively via electronic control strategies. This control is automatic, without the driver having to intervene. The location and number of hybrid phases per lap are determined by the FIA for each race track.

The CSR2 Audi R18

The 5 purple star R18 can fit 135 Fusion parts. So far nothing special. The Audi should run  6.854s. To sum up, the Audi R18 is one of the fastest cars in Tier 5.
