Audi R18 E-tron Quattro Has Three Le Mans Wins on its Account
The Audi R18 e-tron quattro is a Prototype racing car which scored three wins at 24 Hours of Le Mans and won two titles in the FIA World Endurance Championship.
Audi introduced the new R18 TDI Ultra in 2011 to meet new regulations and triumphed at Le Mans what was the beginning of the extremely successful period for the Ingolstadters. In 2012 the Audi R18 e-tron quattro was introduced and over the years earned its place in the history of motorsport.
First victory at Le Mans 24h
The Audi R18 e-tron quattro was lighter than its predecessor. One of the reasons why the new car had to be lighter was for the additional equipment required for the hybrid system. At the front of the chassis some changes also have been made to accommodate two electric motors which can be used only at the speed of over 120 km/h. The energy is stored in an electric flywheel that is mounted alongside the driver.
The Audi e-tron quattro debuted at racing tracks at 2012 Spa 24 Hours and 2nd and 4th respectively. In its second race, the 24 Hours of Le Mans, the Audi R18 e-tron quattro driven by Andre Lotterer, Marcel Fassler, and Benoit Treluyer triumphed ahead of another R18 e-tron quattro of Rinaldo Capello, Allan McNish, and Tom Kristensen. Later in the season Audi scored another two wins in the World Endurance Championship and Audi became the Manufacturers’ Championship title.
Developed 2013 version again was successful
Some development was done before the start of 2013 campaign. The main change was that the well-recognized exhaust was split. The aerodynamics also has been modified while for the Le Mans 24h completely new aero package with a special long tail was created. The 2013 Audi R18 e-tron has six automatic modes that are driver selectable on the steering wheel.
It was another successful season for the ’Four Rings’. The WEC Manufacturers’ title was defended after the Audi R18 e-tron quattro won 6 out of 8 races. The second consecutive victory at Le Mans 24h was scored, this time by Allan McNish, Loic Duval, and Tom Kristensen, while the second car finished 3rd.
Audi constructed a completely new machine under the same name
For the season of 2014, due to regulation changes, Audi had to build a completely new machine but the name remained the same. The aerodynamics have been heavily revised, as well as V6 TDI engine with an electric turbocharger. The new car also has an upgraded kinetic energy recovery system, exhaust heat recovery system, while the monocoque safety has been strengthened.
Third consecutive victory was scored at Le Mans, this time by Lotterer, Fassler, and Treluyer, while the car of Tom Kristensen, Lucas Di Grassi, and Marc Gene finished 2nd in the race. Audi lost its WEC crown to Toyota, so the new car with the same name wasn’t as successful as its original version.
The end of the Audi R18 era
Another revised version of Audi R18 e-tron quattro was used in 2015 and scored two wins. It has more power from 4.0 l V6 diesel engine and a significant increase in the hybrid system’s power output. That car in its last season scored two wins over the season while Audi for the second year in a row finished as a runner-up in the standings.
The last race of Audi R18 e-tron quattro was the 6 Hours of Spa in 2016 and after that the new R18 was introduced. Surprisingly, that was the last year for Audi in the FIA WEC after Team Joest decided to not to participate in the series from 2017.
