The 2015 Audi R18 e-tron quattro has made its online appearance and it will take part in FIA’s 2015 World Endurance Championship. It looks substantially different than last year’s model which triumphed at Le Mans and Audi hopes the revisions made to the car will repeat the 2014 success. The headlights have been reworked and benefit from Audi’s matrix LED and Laserlight technologies while the different front wheel arches come with bigger air inlets.
Audi’s engineers have also modified the engine cover, hood and the front wing whereas the monocoque has been sourced from the 2014-spec model. There are two different body styles suitable for the different circuits in this year’s WEC season. Audi says they have collaborated with Michelin to optimize the chassis while the amount of energy used during a lap has doubled from 2 to 4 megajoules. All the energy obtained during braking is used when the racecar is accelerating to grant more power.
The 2015 Audi R18 e-tron quattro weighs 870 kg (1,918 lbs) and is powered by a V6 TDI 4.0-liter engine developing 558 HP (410 kW) teamed up with an electric motor granting an additional 272 HP (200 kW). Compared to last year’s model, the turbodiesel engine now consumes 2.5% less fuel than before while the encapsulated flywheel energy storage system now holds 700 kilojoules, representing a 17% increase.
