The Audi R18 is a Le Mans Prototype (LMP) endurance racing car designed bu Ulrich Baretzky as a successor to the Audi R15 TDi,. the R18 uses a TDI turbocharged diesel engine but with a reduced capacity of 3.7 litres and in a V6 configuration, and increased to 4 litre from the 2014 season on The R18 is also the first racing car from Audi to feature hybrid power.
The R18 numerical designation was introduced to the cars in 2011 and as season on season new cars were developed would ordinarily advanced in number, Renault hold the trademark for R19-35 so the R18 number was retained.
In 2012 Audi introduced an evolution of the original car called the R18 ultra and R18 e-tron quattro which won Le Mans. Both the Ultra and e-tron quattro R18 were run at the 2012 24 Hours of Le Mans. In addition to the changes required by the regulations (reduced air intake restrictor and 60 litre fuel tank) the car was completely reworked to reduce weight. These changes included Xtrac sequential electrically activated 6-speed racing gearbox . gearbox with gearbox housing made of new carbon-fiber composite with titanium inserts, carbon clutch, changes to the carbon-fiber composite aluminum honeycomb monocoque built by Dallara Single Garrett (Honeywell Turbo Technologies) turbocharger with boost pressure limited to 280 kPa absolute with Bosch engine management.
For 2013 the R18 e-Tron Quattro is a hybrid version of the R18 ultra, with a 500 kJ flywheel accumulator system designed by Williams Hybrid Power, two 101 PS (74 kW; 100 hp) Bosch Motor Generator Units driving the front wheels with water-cooled integrated power electronics, providing the car with four wheel drive (quattro), and a smaller 58-litre fuel tank. The quattro system, as per the regulations, is available only at speeds above 120 km/h The e-tron has six automatic modes that are driver selectable on the steering wheel. The modes manage engine mapping, short bursts accelerating from corners, quattro four wheel drive, wet weather, etc.
The 2014 car include the introduction of blue laser beam backlights with a yellow phosphor crystal lens complementing the LED headlights, a revised V6 TDI engine with an electric turbocharger, upgrades to the flywheel accumulator system and an exhaust heat recovery system. The system captures the thermal energy from the exhaust and can add power to either the turbocharger or the flywheel accumulator system The aerodynamics have been heavily revised in accordance with the new rules: the width is reduced by 10 cm, the height is increased by 20 mm and there is a new set of front wings. However, the exhaust-blown diffuser on the 2013 model has been banned and removed. The safety monocoque has been strengthened with additional fabric. Wheel tethers and extra crash structures are also added to the car.
For 2015 aerodynamics were significantly improved and the turbocharged 4.0L V6 diesel engine now produces more power while using less fuel. The flywheel accumulator system's capacity has been increased from 500KJ to 700KJ as the 2015 Audi's energy output per round has been increased from 2MJ to 4MJ. Changes also include a significant increase of the hybrid system's power output.
For 2016 The new R18 featured significantly altered aerodynamics, including a raised nose similar to pre-2014 Formula One nose designs, air scoops above the front fenders, integrated mirrors, and other body modifications. The KERS for the 2016 R18 has also been changed from a flywheel system to a lithium-ion battery, and has been upgraded to the 6MJ class from the 4MJ class to improve boosting. The engine remained with the same 4.0L turbodiesel V6. Audi dropped the e-tron quattro name badge for the 2016 season.
The 2015 season again saw a pair of R18 e-Tron Quattros race throughout the WEC season with three car entries at Spa and LeMans. Audi accumulated 264 point for the season, an improvement of 20 points over 2014 but still finished second in the manufacturers Championship. At LeMans were R18s had already won the 2011,2012, 2013 and 2014 races. The three car entry saw car number 7 driven by Andre Lotterer, Marcel Fassler, and Benoit Treluyler finish best of the Audi entrys in 3rd narrowly beaten by a pair of Porsche 919 Hybrids, car number 8 followed 7 home in fourth with car number 9 in seventh
