Ingolstadt-Audi Motor Sport race car has introduced the R18 in the race FIA World Endurance Championship (WEC) and the Le Mans 24 hours. This car be hotshot Audi in the 2016 season.
In a statement, Audi says, the R18 was redesigned from scratch and almost nothing in common with its predecessor. Audi has been focusing on fuel efficiency to meet FIA regulations of the WEC.
Thanks to the new regulation, car racing required fuel consuming ten percent less than before.
To that end, Audi change direction with a hybrid system of 1000 horsepower on this car. Audi race car uses a lithium-ion accumulator as hybrid energy storage systems.
A system called Motor Generator Unit (MGU) located in the front axle produce energy and change the movement of the front wheels into electrical energy when the driver braked.
In addition to the side of performance, Audi also improve in terms of aerodynamics as on front piece. The air flow is directed to the top of the car and between the wheels, cooling channels, entering through the body shell. At the rear, the air out through the diffusor to produce downforce.
All the improvements it has made better fuel efficiency to 32.4 percent compared to first generation in 2011. Audi is now using the turbo is lighter and more efficient.
Overall concept clearly more efficient
The efficiency increases of the race car are remarkable in a historic comparison. The current V6 TDI consumes 32.4 percent less fuel than the first generation did in 2011. This progress is even more substantial in a comparison with the original year of 2006. Back then, Audi used TDI technology for the first time. Thanks to this technology, the brand with the four rings has since clinched eight victories, a distance record, plus two world championship titles. Today, Audi's LMP1 race car with the current engine uses 46.4 percent less fuel at Le Mans. Still, it achieves lap times that are ten to 15 seconds better than a decade ago. All of this is possible thanks to the sum of all the advances that have been made in the areas of aerodynamics, lightweight design and the powertrain.
Distinctive safety
In terms of safety, the LMP1 race cars will continue to set standards in the future as well. Audi complements the exacting requirements of the regulations by in-house research that far exceeds these rules. In the field of active safety - in other words the detection of hazards and accident prevention - the Audi drivers can draw on a wealth of tools. While the driver information monitor in the cockpit to display race control flag signals is prescribed, Audi assists its drivers with a number of additional solutions. For instance, Matrix LED headlights combined with Audi laser light optimize the light beam of the race cars that can reach speeds of up to 340 km/h. Since 2015, Audi customers have been able to order laser light in the second generation of the Audi R8 as well. Matrix LED technology has been making its way into a growing number of model ranges.
Particularly good rearward vision is provided by a lightweight and energy-efficient camera system in combination with an ultramodern AMOLED screen that serves as a digital rear view mirror. Since the 2001 season, the drivers and pit crews have been keeping their eye on tire inflation pressure using a tire pressure monitoring system. And, last but not least, the Audi R18 automatically controls brake force distribution with respect to the hybrid system in the respective operating condition.
In the event that an accident cannot be avoided, the passive safety systems take effect. The monocoque consists of a high-strength CFRP structure with an aluminum honeycomb core and has a front crash nose for energy absorption. In 2011, Audi was the first manufacturer to use a single-piece monocoque. The cell has been provided with additional side impact protection, as Zylon layers integrated into the cockpit walls prevent the intrusion of objects. In rear-end collisions a CFRP structure at the transmission absorbs the impact energy. Double wheel tethers have been successfully used since the 2014 season and reduce the risk of wheels separating from the race cars in accidents. Due to their rotary motion, wheels have high levels of kinetic energy. The high-voltage protection systems ensure that the electrical currents in the hybrid system can be safely controlled. There is no other motorsport discipline that uses an equal amount of high technology to protect the driver before or during an accident.
Be it in terms of the performance capabilities and safety of the race cars or the furthering of efficiency and innovations: in the sum of all technological features, the LMP1 class remains unique around the globe and therefore of utmost relevance for the future of the automobile.
