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. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.

Audi waxes poetic about Le Mans

Audi did it again this year at Le Mans, but it wasn't arguably a harder job than it's been in the past few years. The Four Rings has put together a five-minute recap of the 24 hours in the wet and the dry at La Sarthe, showing a lot of the low points and the one high point that makes them all worth it.
Perhaps even better than the footage are the driver interviews. Audi has owned Le Mans for more than a decade, but none of the drivers take it for granted - team driver Marc Gene said, "I also think that Le Mans picks the winner... At some point, he just decides which car and which drivers are going to win that race."
You can check it out in the video below. And be sure to hang around for the tribute at the end.

Audi looking for Tesla-style, non-traditional way to sell EVs

As part of Audi's notable EV emphasis at the Los Angeles Auto Show last week, there was a bit of a secondary discussion on just how the automaker might get to the point where 25 percent of all of its sales would be electric vehicles. After all, no major automaker has figured out how to crack into the double-digit percentage of plug-in vehicle sales. The problem might be, as The New York Times noted recently, that traditional dealerships just don't know how to sell EVs. While no one at Audi was saying that the automaker is going to open up its own EV stores, like Tesla has, but two Audi of America executives were certainly warm to a different style of how an automaker can encourage EV sales. Filip Brabec, AoA's director of product management, said that Audi is at least considering making changes, including some sort of different dealership experience and perhaps a new kind of test drive. "The traditional automotive approach is not necessarily working," Brabec said. "A lot of it has to do with the complexity of the product and the complexity of the offer and it's difficult, I think, to bring that into a classical dealership and sort of treat is as another car and off we go. I think there needs to be some differences in how we go in the future." AoA president Scott Keogh said that Tesla has shown the rest of the industry how to make selling EVs a complete experience. It's not just about the car, he acknowledged. "I think we have to give Tesla credit where it's deserved," he said. "I think the charging network, at least from a public relations point of view, is quite strong and that's definitely added to the message." So many automakers want to have that, "Tesla fighter," as we've heard over and over recently, but Keogh hinted that Audi could do a better job than Tesla is doing today. "I think they've done a good job of looking at the full package. I think we have some resources and the network and everything else that we can put a fuller package together." The most important part is getting people into the cars, Brabec said. "I think exposing consumers to EVs, letting them experience EVs is another big aspect, and probably different than we have today, because test driving a car today is a very conventional thing. It's probably not going to be as conventional with EVs, particularly if you've never been in one before." We can't wait.
