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.

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.

World Car of the Year finalists announced

To say the 2014 Geneva Motor Show was packed full of news is an understatement as big as the show's home at the Palexpo convention center. Despite everything that we were able to cover during this year's show, there's still more coming out of Switzerland, including the announcement of the finalists for the 2014 World Car of the Year Awards.
We reported on the original list of finalists over three weeks ago, and now, that initial list has been pared down to three finalists for each of the five awards. The finalists were announced at a press conference by frequent Autoblog contributor and co-chair of the awards, Matt Davis (above).
The finalists for the overall title of 2014 World Car of the Year are the Audi A3, the BMW 4 Series and the Mazda3. The World Luxury Car of the Year will be either the Bentley Flying Spur, the Mercedes-Benz S-Class or the Land Rover Range Rover Sport, while the Performance Car of the Year will be awarded to the Chevrolet Corvette Stingray, the Ferrari 458 Speciale or the Porsche 911 GT3 (which, um, yeah...).

Audi on Demand pilot program launches in San Francisco

Customers eager to drive a new Audi but unwilling or unable to plunk down the purchase price for one will be intrigued by the launch of the new Audi on Demand program. Initially being rolled out in San Francisco, Audi on Demand is based around an iPhone app that allows clients to order up a new Audi of their choosing on a day-by-day basis for up to 28 days in a row. Order an Audi through the app and a "personal concierge" will deliver the car anywhere in the city – curbside, driveway, parking lot, office building... pretty much anywhere the customer chooses. The concierge will even help set up the audio and navigation systems to the customer's preferences. And if the customer isn't there to receive the vehicle in person, he or she can simply unlock it through the app, start it up and drive off. The service is being made available on a broad range of Audi models, from the A4 all the way up to the R8. Customers can even specify a child seat or (on an Allroad or Q5) a ski or bike rack, and are guaranteed that the vehicle they select will be the one they get, right down to the color and trim. Though being launched at first only in San Francisco, Audi says it will roll out the program in other American cities "in the coming years." In announcing the program, Audi also revealed that it's planning to launch Audi at Home as well, a "micro-sharing" service that will allow residents of select condo complexes to share a fleet of Audis as well. These, of course, are just the latest smartphone-enabled conveniences being introduced by the German automaker, following its collaboration with Amazon and DHL for in-trunk delivery.
