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.

VW won't let emissions scandal keep it from racing

The Volkswagen Group may have its hands full dealing with the diesel emissions scandal. But that doesn't mean it will be curbing its considerable racing programs. At least not in any significant way. This according to Matthias Muller, who recently moved up from his previous position as Porsche CEO to preside over the entire group. Speaking with Autosport at the World Endurance Championship finale in Bahrain this past weekend, Muller emphasized the importance of racing to the company. "The motorsports programs are not in danger of being dropped or significantly reduced because motorsports is very important for the group and the brands," said Muller. "Basically we do not question our motorsport efforts." Of all the brands under the group's umbrella, several have prominent, top-level factory works racing programs, and others support customer racing teams. The Volkswagen brand has emerged as the dominant force in the World Rally Championship, securing both titles over the past three years. Both Porsche and Audi compete in the top tier at Le Mans and in the World Endurance Championship, trading places in the winner's circle. Audi also competes in DTM, and alongside Lamborghini, Bentley, and Porsche, and also offers GT3 and GTE racing cars to private customers. Lamborghini, Porsche, Audi, and Seat (once the leader in touring cars) all run their own spec racing series as well. Skoda continues to compete in lower-level rallying, leaving only Bugatti to draw on its prominent pre-war grand prix racing history. To hear Muller tell it, those racing programs – or at least the top-levels ones among them – aren't going away anytime soon. But there may still be some tweaks here and there, and we shouldn't expect any new programs to be launched in the near future. Porsche, for example, is anticipated to wind down its factory involvement in GT racing, after winning both the drivers' and manufacturers' titles in the WEC GTE Pro class this year in addition to its LMP1 victories. Instead it will focus on preparing new racing versions of the 911 for client racing teams. The auto giant was also reportedly close to branching out into Formula One in partnership with Red Bull. But after negotiations were interrupted by emergence of the diesel emissions scandal, that deal fell apart. It remains unknown which brand might have been represented in the F1 engine-supply program.

Road & Track names its 2013 Performance Car of the Year

Road & Track recently staged its first annual Performance Car of the Year test, pitting 13 new and updated performance cars against each other on track, then graduating the top six to a road test before picking a winner. Additionally, the magazine staff picked the best automobiles of the year in eight categories.
But first, let's cover the PCotY segment. Here's the list of cars brought to the comparison test: Audi R8 V10 Plus; BMW 435i; BMW M6 Competition Package; Chevrolet Corvette Stingray Z51; Ferrari F12 Berlinetta; Ford Fiesta ST; Jaguar F-Type V8 S; Jaguar XFR-S; Mercedes-Benz E63 AMG S-Model Wagon; Mercedes-Benz SLS AMG Black Series; Mini John Cooper Works GP; Nissan GT-R Track Edition; and Porsche Cayman S.
To find out the results of the comparison, head over to Road & Track's website or check the press release below, where you'll also find the magazine's top-rated vehicles in eight categories. Want more? Head over to the 2013 PCotY hub. But before you do that, take a stab at guessing the winner of PCotY (we'll give you one hint: it isn't a Porsche).
