Audi calls R18 E-Tron Quattro its 'most complex race car'

Technically speaking, Audi's R18 E-Tron Quattro is quite technical. The German automaker says the diesel-hybrid is the "most complex race car" it's ever created. And we'll take their word for it. The Audi, which pairs a V6 turbodiesel powering the rear wheels with two electric motors, is all about connectivity, giving the car's crew the opportunity to constantly monitor the vehicle while it's racing. The car sends in a host of data each lap to the crew's computers, and the vehicle's telemetry system constantly keeps tabs on things like hybrid energy levels, cockpit temperature and boost-pressure levels. In all, the amount of data parameters is more than 100 times greater than in 1989, when Audi first tested a race car equipped with automatic data transmission capabilities. Audi first released specs on the updated version of the R18 E-Tron Quattro late last year, trumpeting the vehicle's advantages in competing in the LMP1 class of the 2014 World Endurance Championship (WEC). Audi made the car a little narrower and a little taller and it complies with a new WEC regulation requiring the front end set off by a new wing. Take a look at Audi's most recent press release below. AUDI R18 E-TRON QUATTRO WITH COMPLEX ELECTRONIC ARCHITECTURE • Telemetry connection between race car and pit lane • Permanent acquisition of far more than 1,000 parameters • Various electronic control units interlinked by a multitude of CAN Bus systems Ingolstadt, May 5, 2014 – The Audi R18 e-tron quattro is the most complex race car created in Ingolstadt and Neckarsulm to date. This not only applies to the mechanics. The electronics of the most recent LMP1 race car with the four rings is more sophisticated than ever before. The age of electronic data transmission from the race car on track began for Audi in 1989. At that time, an Audi 90 quattro in the IMSA GTO series radioed eight parameters to the garage where engine speeds and a few pressures and temperatures were plotted on printouts – a tiny step from today's perspective, but one that provided important insights at the time. Today, an Audi R18 e-tron quattro on more than a thousand channels, in cycles that in some cases only amount to milliseconds, generates data of crucial importance to a staff of engineers at Audi Sport. At Le Mans, the engineers constantly monitor their race cars for 24 hours.

Shuffle at Lamborghini sends CEO to Quattro GmbH

A management shakeup in Volkswagen Group's high-performance divisions will make Stephan Winkelmann (above) the new chief executive of Audi's Quattro GmbH on March 15. On the same day, former Scuderia Ferrari team principal Stefano Domenicali will replace Winkelmann as Lambo's boss. These changes are necessary because current Quattro chief Heinz Hollerweger is retiring. Rumors of these exact shifts cropped up in Italian media in December. Winkelmann began leading Lamborghini in 2005, and he has been at the helm for massive growth at the company. In 2015, the Italian supercar maker delivered a record 3,245 vehicles, and it had just set its previous best of 2,530 units in 2014. His new role at Quattro GmbH puts Winkelmann in charge of Audi's equivalent to M at BMW or AMG at Mercedes-Benz. The division is responsible for the Four Rings' R and RS production models, the Audi Sport customer racing program, and Audi Exclusive customization service. "In the future, the Audi Sport brand is to be positioned more clearly," the company's announcement said, which hints at one of Winkelmann's duties. Domenicali has been closely associated with Lamborghini rival Ferrari during his career and had years of experience within the automaker's racing team. He started in financing at the Prancing Horse in 1991 and moved to business planning for the Scuderia Ferrari F1 squad in 1993. He held many positions there and eventually ascended to the top as team principal in 2008. Domenicali resigned from leadership in 2014 because of the team's poor performance, but Audi quickly snapped him up as its as Vice President New Business. He now gets the reins of one of Italy's premiere supercar makers.

Winkelmann was President and CEO of Automobili Lamborghini S.p.A. since January 1, 2005. Heinz Hollerweger (62), the current Head of quattro GmbH, is to retire after almost 40 years of successful work for Audi. "With his experience from more than eleven years in charge of Lamborghini, Stephan Winkelmann will be a key contributor to the further growth of quattro GmbH," says Rupert Stadler, Chairman of the Board of Management of AUDI AG.

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.
