AUDI R18 E-TRON QUATTRO 2015

General description

Audi would revise their R18 e-tron quattro. Audi chose to upgrade the prototype to the 4MJ hybrid output class from the 2MJ. Although the 2015-spec car is a car that resembles the previous year's model, the aerodynamics been altered. The new aerodynamic package allowed for airflow through and around the front end, through the side panels, and at the rear of the car with the diffuser. The monocoque remains unchanged from last year, but there is modified sidepod airflow with new radiator configurations in the monocoque structure to not only aid in necessary engine cooling, but to cut down on the created drag from the openings. The engine cover at the rear of the car is slimmer, so the car can cut through the air more efficiently. The headlights have been updated with Audi Matrix LED and Laserlight technologies. With the increased megajoule output, the electrical hybrid machine in the front axle produced more 272 BHP, which recovers energy during braking. The flywheel (in passenger side of the car) can store up to 700 kilojoules of energy. The 4.0 liter V6 engine has been further developed to produce 558 BHP, with better-optimized fuel consumption, despite a reduction in the regulations for a lower fuel capacity. The prototype weighs in at 870 kg.

Audi chose to run car numbers #7, #8, and #9 for the 2015 season. The #7 and #8 entries would be full-time entries and the #9 car would only be utilized for the second and third rounds, at Circuit de Spa-Francorchamps and Le Mans. The #7 would be driven by André Lotterer, Benoît Tréluyer, and Marcel Fässler. The #8 car would be driven by Oliver Jarvis, Lucas Di Grassi, and Loïc Duval. The limited round entry of the #9 car would be driven by Marco Bonanomi, Filipe Albuquerque, and René Rast. The #9 car would be only eligible for manufacturer points at Le Mans, while the drivers would be able to receive points based on finishing position for each race they raced.
