Audi has unveiled the thrilling R18 e-tron quattro Racecar. The basic structure is similar to its predecessor, but the car makers have brought about significant modifications to give the vehicle its best possible form. A new method has been used for conducting airflow through and around the front end, in the rear and in area of sidepods. With the sidepods, the air flow gets modified and the radiator configurations too have been revised to for the cooling of the powerful engine. The cover of the engine now houses the engine more tightly. The cover then tapers behind the car’s cockpit.
The aerodynamic drag has been brought down by enlarged inlets in the wheel arches in the front. The headlights too receive a fresh look. Matrix LED has been used for the lighting units. This is accompanied by Audi Laserlight. These two features together guarantee better active safety in the road traffic.
Audi has worked on energy recovery too. For the 2015 model, the amount of energy has been doubled. From 2 megajoules it has reached 4 megajoules/ race lap in Le Mans. The power figure too is a significant improvement as compared to 2014- the engine generates over 272 hp. The capacity of energy storage system has been enhanced as well. The flywheel energy storage system alongside the car’s driver in the cockpit, is capable of storing a maximum of 700 kilojoules energy. This energy then goes back to electrical machine- that is 17% greater as compared to the system in 2014.
The company has kept the weight at bay despite of the cool improvements in performance- it weighs just 870 kg minimum. The R18 e-tron quattro Racecar borrows the monocoque from Audi’s previous model. The body element has a crash structure. For 2015 season, the company has already performed a new crash test.
