Electric R18 e-tron from Audi is very fast and cool and it is the best place to test the new technology up to the limit at 24 Hours of Le Mans!

Lithium Drive: Future of Audi electric vehicle design - David Caffrey 

"German automakers are better hurry now to be in time for the electric cars to take the market by storm. GM looks like has bought a ticket into the future breakthrough Lithium Battery technology with Envia news about its wonder battery with 400 Wh/kg Energy Density and the cost dropping to $125 per kWh. Envia talks about 300 miles range for electric cars in sight now and GM is backing the company in its research. 

  DBM Energy has been lost in translation recently - before German start up has announced ground breaking claims about the range and cost for its Kolibri Lithium Battery. Will this technology appear somewhere in the German cars now? 
   Renault Zoe 2014 reported could have 220 miles range and this has not been confirmed by the company yet, but by all means looks feasible now. Tesla CEO Elon Musk is adding fire to the sector with his own claims about the cost of Lithium Batteries dropping below $200 per kWh in the nearest future. With Oil prices pushing Gas prices higher by the day, interest to Electric cars and Hybrids is reported to be growing now and these breakthroughs in lithium battery technology will make Electric Cars  for all very soon."

Audi brings the quattro back to the race track- World premiere in Munich: the new Audi R18 e-tron quattro- Four-wheel driven diesel hybrid for the 24 Hours of Le Mans- Audi ultra lightweight as base for the application of hybrid technologyMotor sport is used yet again by AUDI AG to pioneer new technology: the brand with the four ring's new Le Mans race car is the world's first LMP1 car to combine a highly-efficient TDI with a hybrid system. quattro drive also celebrates its comeback to the race track with the prototype -- in a entirely new form.Audi R18 e-tron quattro is the name of the new Le Mans prototype that makes its race debut on May 5 in the 6-hour race at Spa-Francorchamps (Belgium) and fights for overall victory at the famous 24 Hours of Le Mans (France) on June 16/17. Audi unites two technologies in a fascinating way to create a new type of drive, which is also already being tested for future use in production cars: e-tron quattro.Hiding behind this description is the next generation four-wheel drive with which Audi combines the advantages of the proven quattro drive with the potential of electromobility. To this end one vehicle axle is powered conventionally, the second by electric motors."Audi has always consciously selected championships and categories in racing that have a close relationship to production and therefore have technical relevance for the Audi customers," explains Head of Audi Motorsport Dr. Wolfgang Ullrich, who personally drove the new Audi R18 e-tron quattro onto the stage on Wednesday evening during its world premiere in the Audi Training Center at Munich airport -- electrically and almost silent. "quattro, TFSI and TDI are three excellent examples of how motorsport has stimulated production development. A similar tendency is apparent with the e-tron quattro: we test a completely new technology on the race track before it's introduced to the Audi production line."On the Audi R18 e-tron quattro kinetic energy is recovered on the front axle during the braking phase. It is fed as electric into a flywheel accumulator before being retrieved under acceleration again above a speed of 120 km/h. During this procedure only the front axle is integrated. The V6 TDI power plant producing 375 kW (510 hp) continues to transmit its power to the rear wheels. Both systems complement each other to create the new drive principle e-tron quattro.Project began in February 2010The project e-tron quattro for motorsport started in February 2010. Only 18 months passed from the initial conceptual ideas to the first test. "This is a relatively short cycle for a technology that has never been tested in motorsport and which still doesn't even exist in production," stresses Dr. Martin Mühlmeier, Head of Technology at Audi Sport. "The challenge is correspondingly big."Audi Sport developed the Audi R18 ultra in parallel to the Audi R18 e-tron quattro -- because Audi takes a two-pronged approach this year in the 24 Hours of Le Mans and in the newly created FIA World Endurance Championship (WEC) -- the 2012 model year Audi R18 is built with and without hybrid drive. The trick: the base of both cars is completely identical, which is why the additional logistical effort is kept limited for Audi Sport and the race team."The TDI engine invented by Audi is still the most efficient drive in the world," says Dr. Wolfgang Ullrich. "We are convinced that the TDI has even more potential. This is why Audi not only supports the hybrid in motorsport as it does in production, but in parallel also the further development of the conventional drive."Innovation in transmission areaThe R18 e-tron quattro's twin brother more than lives up to its model name 'R18 ultra': it is the lightest Le Mans prototype that Audi Sport has ever built. To compensate for the additional weight of the hybrid system the subject of lightweight design and construction was the focus throughout development of the 2011 Le Mans race winning R18 TDI. In addition to the many detail optimizations there is also a genuine innovation in the transmission area: a new gearbox with a carbon-fiber composite housing was developed for the R18 -- a premiere for endurance racing."The new R18 ultra is a distinct evolution of last year's Le Mans race winning car," summarizes Head of Audi Motorsport Dr. Wolfgang Ullrich. "Our drivers' impressions were very positive from the first moment. Without the weight optimized R18 ultra we would have not been capable of realizing the R18 e-tron quattro which is absolutely identical with the exception of the hybrid system."
