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.

Nine-time Le Mans winner Tom Kristensen to retire

Le Mans icon Tom Kristensen is retiring. The Danish driver, who was an integral part of Audi's absolute dominance at the 24 Hours of Le Mans, captured a record-breaking nine wins at the legendary endurance race, along with six overall victories at the 12 Hours of Sebring in a career that spanned 26 years.
"Over the past couple of months, my thoughts of retiring have been stronger, and therefore, it feels right to inform you today that I am retiring from motor racing," Kristensen told Autosport. "I still feel I am in peak physical form and possess the necessary mental toughness both in and outside of the car: it has been important for me to stop while I am still strong and able to deliver top performances at Audi."
While the World Endurance Championship's season-ending race at Interlagos on November 30 will be Kristensen's last as a driver, it won't be the end of his long-running association with Audi. According to Autosport, TK will take on a new role as an ambassador for the German marque and will work with team's drivers in an unspecified role.

Audi teases 700-hp Quattro Sport E-Tron concept for Frankfurt

Audi's trump card for the 2013 Frankfurt Motor Show has just been unveiled, sort of. It's called the Quattro Sport E-Tron Concept. Set to debut in a few weeks, sketches have been uncovered that show a few of the car's details, albeit in rough form. The news of a big-name Audi concept at Frankfurt has been swirling since June, when we first reported on it.
From the sketches, we see a car that has the same basic shape as the Quattro Concept from the 2010 Paris Motor Show, only with subtle tweaks and evolutions to a few features. The news isn't so much about the looks, though. It's the reports coming from Auto Zeitung and Audi enthusiast site Fourtitude.
Horsepower on the concept is expected to be in the neighborhood of 700 ponies - about 50 more than we initially thought - and will be split between a gas engine and an electric motor. Yup, that "E-Tron" name isn't just there for show. While it's not clear what the exact split will be between gas and electric power, we do know the same twin-turbo 4.0-liter V8 found in the RS6 and RS7 will be sitting under the Quattro's hood, and that the bulk of the power will likely come from here. We may not have power figures on the hybrid system, but we do know this concept is capable of running for 21.7 miles on electric power alone.
