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.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. 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.

Audi Sport Quattro Concept to spawn volume sports car?

There have been two modern re-imaginings of the original 1984 Audi Ur-Quattro: the Quattro Concept of 2010 (shown above) and the Sport Quattro Concept revealed at the 2013 Frankfurt Motor Show. In between them, there have been numerous rumors about what, if any, kind of production car Audi might make of them. According to a new report in Auto Motor und Sport, Audi CEO Rupert Stadler has "indicated... that the car will come," and based on the specs presented, what we get might end up being a mix of the two.
Ulrich Hackenberg, Audi's head of R&D, apparently wants a sports car with wider appeal than the 700-horsepower hybrid Sport Quattro Concept. AMS says his vision would be built on a modified A6 platform - the same MLB architecture under the Sport Quattro Concept - with ample use of carbon and aluminum keeping the weight down to around 1,300 kilograms (under 2,900 pounds). Engines could include a 2.5-liter, five-cylinder (like that of the original, smaller Quattro Concept) offering anything from 310 to 360 hp. Those numbers would be at least 48 horsepower shy of the first concept, but a less-powerful entry point to a new model range would provide a lower cost of entry. Besides, a full model range would likely include a significantly healthier powertrain option on the top end.
At the moment, Hackenberg is said to be unsatisfied with the design of the car, which could well mean we'll get another concept car before a production version appears.

Audi gets Q2 and Q4 badges in trademark swap with FCA

Audi has swapped trademarks with Fiat Chrysler Automobiles to snare the rights to the Q2 and Q4 badges for upcoming crossover SUVs. Audi CEO Rupert Stadler confirmed at the Detroit Motor Show that the automaker had finally persuaded FCA to release the two names that would let Audi lock up the Q1 to Q9 badges for its growing SUV family. Audi already plans to drop the Q2 name onto its MQB-based city crossover five-door this year, while the Q4 badge will slot onto the rump of a coupe-like version of the next Q3. It will also reserve the Q1 badge for a 2018 baby crossover, based around the architecture of the next A1 hatch. The A1 will share a lot of its engineering with Volkswagen's Polo-based soft-roader, dubbed T-Cross in concept form. The German company has also pounced on the naming rights for SQ versions of all of its Q-cars, along with F-Tron to cover the day when it pushes hydrogen fuel cell cars into production. Stadler insisted that no money had changed hands in order to pry the two badges off FCA, admitting that they had "each found something we needed." "We promised each other we wouldn't disclose what it cost, but it was not something they were willing to sell," Stadler said. "We tried to get it years ago and they said 'No, never,' but there is never 'never' in business. ... This year I went back to them with a proposal and we talked and there were some negotiations and then we agreed to it." Those negotiations are believed to have centered on a trademark swap with a Volkswagen Group name that FCA desperately (evidently) wants to use on a Fiat, Alfa Romeo, Chrysler, Dodge or Maserati. Asked if Audi had given FCA a trademark in return for Q2 and Q4, Stadler replied, "Something very much like that, yes." Audi has used Italian names on past concept cars that FCA could be interested in, such as the 2001 Avantissimo concept and the 2003 Nuvolari coupe. The latter was named after legendary pre-war racer Tazio, who won grands prix for both Alfa Romeo and Audi's forerunner, Auto Union. Both are unlikely trade chips, with laws in Europe preventing the trademarking of the names of actual people. There is always "quattro" (Italian for "four"), but after investing nearly four decades locking it in as an Audi all-wheel-drive name, it's just not anything like trade bait.
