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's fastest cars won't catch your drift

"I don't like them. I do not see the reason for them. We do not see the sense in sitting there burning the back tires. It's not fast." – Stephan Reil Drift modes are popping up in sports cars all over the world, but Audi Sport development boss Stephan Reil refuses to have anything to do with them, insisting they're a waste of time and tires. So if you want to show off with a wild-looking, tire-smoking, perfectly controlled drift in an Audi Sport model, you will have to brush up on your car control, not your button pushing. "No drift mode. Not in the R8, not in the RS3, not in the RS6, not in the RS4," Reil said. "I don't like them. I do not see the reason for them. We do not see the sense in sitting there burning the back tires. It's not fast." That seems a bit like Reil and his team are missing a trick that is proving popular with enthusiast buyers and isn't technically difficult to do. It's also a whole lot safer than holding down the skid-control button for long enough to switch off all the electronic safety nets, which Audi Sport will actually let you do. "You can do it yourself [drifting] with the ESP off, if you hold it [the button] for three seconds," Reil challenged. "Then it will not intervene for you even when it [the car] is fully out of control, because that's what you asked it not to do. "You wanted the full control by pushing that button. You got it." Almost every fast car, from Ford to Ferrari, now comes with (or soon will) a drift mode so drivers can just stomp on the gas and turn the wheel to instantly look like rally stars. The dangers of do-it-yourself drift control (which our forefathers used to call "driving") make up most of the moral defense for the companies that use the computer-controlled versions. While critics have called drift modes irresponsible, proponents argue that it is far safer than switching off all the safety nets, because there is still a level of skid-control safety behind it. "Drift control is a lot safer than just turning everything off," BMW M chief Franciscus van Meel said during the launch of the M550i xDrive. "The drivers can enjoy the car on a track but it still has another level of safety to catch them if they make a mistake."

2015 Audi S8

You've gotta hand it to the Audi A8. Last year, Mercedes-Benz launched the truly stunning S-Class, putting the rest of the high-dollar luxury flagship class on notice. With the brand-new S-Class turning heads and garnering all sorts of praise from the automotive press, classmates like the BMW 7 Series, Jaguar XJ and Audi A8 started to look, well, old. But Audi didn't see fit to just let its big sedan carry on and let the Mercedes take the cake.
So when Audi refreshed its A8 line for the 2015 model year with only minor updates, I kind of shrugged it off as just a quick way to keep the big sedan fresh until an all-new, hopefully S-Class-trumping version arrives. But then I drove the S8 pictured above, and I'm no longer so sure the Merc's shadow is as big and imposing as it once was.
Spoiler alert: the Audi S8 is simply fantastic.
