The R18 e-tron quattro Le Mans car has more technology packed into it than any gadget Apple has in R and D. I bet the R18 is lighter too. This car has seen many changes in a sort amount of time. The R18 TDI had a one piece frame that made it super rigid and was the first LMP Le Mans car to use full LED lights. It uses a single Garrett TR30R VGT turbo. some what odd considering Peugeots 908 HDI FAP uses twin turbos as well as other teams.
Then the R18 Ultra came along. Ultra standing for Ultra Light. they made changes like a carbon-fiber composite gearbox housing… that was cheap im sure. That and other changes made it the lightest car audi has ever produced! weighing in at about 2,000 pounds. Then the R18 e-ron quattro has just hit the circuits. If the source i found is correct this car weighs in at 1,880 pounds. Ok pick your mouth up off the floor. It has a V6 turbodiesel that makes 510-bhp as well. If you know anything about cars that amount of power attached to a sub 2,000 pound car is just outrageous! The E-tron produces more torque than a F1 car does and it sends that electric power to the front wheels only. Other hybrid lmp1 car send it to all wheels. Audi pushing it only to the front allows the car to torque vector. Meaning the torque helps pull the car as it steers. The new NSX is going to use the same system actually.
so this R18 stays a quattro and true to the audi ways. The hybrid system is pretty cool too! it works with a carbon fiber flywheel that spins at up to 45,000 rpm in a vacuum and fits tightly in its enclosure. Audi worked up a clever safety net for it too. If in a accident the flywheel is moved at all it would hit the casing it is in and the carbon fiber fly wheel basically burns and ends up in tiny pieces due to the speed it spins at. If you did not understand that…this car has a flux capacitor.
