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 execs mulling turbocharged, entry-level R8

The just-launched, second-generation Audi R8 is apparently a pretty fantastic example of Vorsprung durch Technik. While it's sublime to drive, Audi might already be missing some potential sales due to the lack of an true entry-level version in the supercar's lineup. Lending further credence to an earlier rumor about just such a model, company execs are saying to expect an entry-level, turbocharged R8 to launch in the coming years. "It is inevitable that we will go to a turbocharged motor for it at some point," Audi technical development board member Dr. Ulrich Hackenberg said to Motoring. "It would be in this model cycle, to give us a fuller range." The executive certainly isn't mincing words about forced induction, but the V10's position in the lineup is also secure. "It doesn't mean we are not going to do a turbo, but naturally aspirated is here to stay as well," he said. If Dr. Hackenberg's direct assertion isn't enough, Quattro GmbH chief Heinz Peter Hollerweger further clarified to Motoring that the turbocharged engine would slot into the bottom of the R8's range. An unnamed "senior sales and marketing source" within the Audi also said that the company's turbo five-cylinder was among the currently favored choices for the application. The first rumors about the R8 getting a forced induction version arose just a few months ago. At the time, Audi's electrically turbocharged, 2.5-liter inline five-cylinder was considered an option. The model would solve a problem in markets, like China, that severely tax big displacement engines. Customers might not even need to worry about giving up too much performance either. In the Audi TT Clubsport Turbo concept, the powerplant has a total output of 600 horsepower and 479 pound-feet of torque. While 10 fewer ponies than the latest R8 V10 Plus, it would bring 66 lb-ft more twist to the supercar.

Audi, Fiat squabbling over numbers and letters

There have been rumors and speculation and prognostications about a Nissan Juke- and Mini Cooper-fighting Audi Q2 since 2012. There have been the same for a performance-oriented Q4 since 2011, perhaps previewed by the TT Offroad concept shown last year at the Beijing Motor Show. Turns out that those two alphanumeric combos are the only ones missing from the series Q1 to Q9 in Audi's trademark stable, and the Ingolstadt company wants to get them to make its badge sequence and crossover lineup complete. But Fiat owns them, and rumor is, CEO Sergio Marchionne appears to have no interest in selling them. Fiat has used the Q2 and Q4 like trim badges, identifying whether a company product has two-wheel or all-wheel drive. They did it with the Alfa Romeo 159 sedan, and they do it now on the Maserati Quattroporte S and Ghibli S Q4 sedans. Car magazine says Marchionne "may not be categorically opposed to selling the rights," but he absolutely won't do it to any fiefdom in the Volkswagen empire, which would leave Audi a jilted suitor. Why is Sergio being so serious? VW Group CEO Ferdinand Piech first starting waving torches on the bridge between the two companies when he said Alfa Romeo could sell four times as many cars if Volkswagen owned it, then burned the bridge when it continued to publicize its desire to buy Alfa Romeo. VW followed that up by throwing salt on the land around the destroyed bridge with its aggressive pricing in Europe during the worst of the car sales slump there, which Marchionne said was causing a "bloodbath." VW's final flourish was to set the river itself on fire, when a press officer said Marchionne wasn't qualified to head the European Automotive Manufacturers Association (ACEA) and VW would quit the organization if he did take the top spot. That is why, putting it optimistically, Audi looks to have a grim chance of getting the Q2 and Q4 marques from the Italian. So long as he is in power, at least: Marchionne said he's walking away from the job in 2018. Audi might have a better chance bending the knee to, and generously rewarding, his successor.
