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 A3 E-Tron launching at $51,500 in Germany

Audi has put a price tag on the A3 Sportback E-Tron plug-in hybrid, for which presales begin this month in Germany. To get your hands on one of these little guys, Audi is asking for ˆ37,900, or about $51,537 according to current exchange rates. Of course, the base MSRP doesn't include any incentives, but in Germany, those savings would come from certain annual tax exemptions that apply to PHEVs. Buyers in other countries might have more luck in getting into an A3 E-Tron for less. Audi lists its most important markets for the A3 E-Tron as Germany, Sweden, Norway, Holland, the UK and, despite no firm date for the car's arrival here, the United States. These countries, according to Audi, are where buyers are willing to spend their green (or the more colorful banknotes of Europe) on green cars. These places also enjoy nice things, or in Audi's words, "They appreciate the classic strengths of the Audi brand: high-end technology, uncompromising workmanship, sportiness and elegant design." In Germany, Audi will sell the A3 Sportback E-Tron at select dealerships. The service departments of those 100 or so dealers will get special training to work with the high-voltage technology used by the plug-in hybrid. These locations will also feature free-to-use charging stations for customers. The Audi A3 Sportback E-Tron's lithium-ion battery stores 8.8 kWh of juice, and is supplemented by a four-cylinder, 1.4-liter TFSI engine which works parallel to the electric motor. Total output is 204 horsepower and 258 pound-feet of torque, directed to the front wheels via a six-speed S Tronic transmission. The car can reach 60 miles per hour in 7.6 seconds and has a top speed of 138 mph. It can travel of to 31 miles on battery power alone. Deliveries for the 2015 Audi A3 Sportback E-Tron will begin in Germany and Central Europe this winter.

Audi mulling producing version of Quattro showcar, just not sure which one [w/poll]

Head of design for Audi, Wolfgang Egger, has told Auto Express that a reborn Quattro could enter production, but bosses for the company haven't yet decided whether to base it on the Sport Quattro concept that just debuted at this week's Frankfurt Motor Show or the smaller Quattro concept that was revealed at the 2010 Paris Motor Show.
While both draw their inspiration from the original Ur-Quattro of the 1980s, they vary wildly in both size and choice of powertrain. The 2010 Quattro concept was based on Volkswagen's MQB platform, shared with such vehicles as the Golf and Audi A3. The Sport Quattro, meanwhile, was built atop the company's larger MLB platform that's used almost exclusively for Audi models, including the A5, which is also a coupe.
Under their hoods, the 2010 Quattro concept simply employs a version of the same 2.5-liter engine used in the TT RS, tuned to deliver 408 horsepower, while the Sport Quattro goes nuclear with a twin-turbo V8 hybrid powertrain that develops 700 hp and 590 pound-feet of torque. Both, of course, employ quattro all-wheel drive just like their forebearer.
