Notes from Day One of the 2013 Twelve Hours of Sebring

The 61st edition of The 12 Hours of Sebring is on, and Autoblog has come to central Florida with Audi to feast on jumbo boiled peanuts, pickled eggs and the final race for the LMP1 class at the oldest road course in North America. As Audi has been doing for more than a decade now, it's brought its latest endurance race car, the 2013-spec R18 etron quattro, to Sebring to begin testing for Le Mans.
Why the commitment to Sebring? Audi Sport executives have repeatedly called Sebring "punishing," "extremely demanding" and "one of the toughest tracks in the world." It is a 3.47-mile circuit that, in places, feels like it was made from the leftover bits of other circuits. Doing the 12-hour distance in Florida is thought to be a good start on lasting the 24-hour distance in France, and we can't think it a coincidence that Audi has won ten times here in the last 13 years and 11 times in Gaul.
Where there's rhyme - and victory - there is reason. We think we found a few of them on our first day where preparation, technology, fastidious attention to detail and sweat fit right in with swamp cabbage...

Audi builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.

Audi starts new e-gas partnership with Global Bioenergies

Audi continues to try to build its green-car cred with one more partnership to produce synthetic fuels made from renewable resources. The German automaker is hooking up with France-based Global Bioenergies to make a synthetic biofuel called e-gasoline. Audi says making this e-gas "does not create competition with food production and farmland," nipping that argument in the bud. Last summer, Audi opened a power-to-gas facility in Werlte, Germany. That factory produces hydrogen and synthetic methane, which are made from renewable energy sources such as water and excess carbon dioxide. The E-gas plant uses electrolysis to split water molecules into oxygen and hydrogen; those elements will later be set aside to power fuel-cell vehicles but in the near term, the plant will make synthetic natural gas. Audi started delivering e-gas in Germany in the fall of 2013 and estimated that it would make enough of the stuff each year to power 1,500 Audi A3 Sportback G-tron vehicles for more than 9,000 miles. Audi also operates a research facility in Hobbs, New Mexico, with renewable fuel company Joule. That plant produces e-ethanol and e-diesel. Check out Audi's press release about its new Global Bioenergies partnership below. Audi launches strategic partnership with Global Bioenergies Premium carmaker and biotechnology company developing the drop-in biofuel Audi e-gasoline Reiner Mangold, Head of Sustainable Product Development: "Another step closer to carbon-neutral mobility with Global Bioenergies" e-gasoline part of the big Audi e-fuels strategy Audi is launching a strategic partnership with Global Bioenergies. The carmaker will work with the French biotechnology company to promote the development of non-fossil fuels. In addition to the Audi e-gas and e-diesel projects, the research into e-gasoline is part of Audi's persistent efforts to find alternative fuels. Reiner Mangold, Head of Sustainable Product Development at AUDI AG: "We're taking another step closer to carbon-neutral mobility with our partners at Global Bioenergies. We are supporting an innovative technology here which can be used to produce renewable fuel. This process does not create competition with food production and farmland." e-gasoline is part of the overall Audi e-fuels strategy. Audi is already operating a research facility for the production of e-ethanol and e-diesel with its partner Joule in Hobbs, New Mexico. The Audi e-gas plant in Werlte began feeding into the grid a few months ago.
