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 RS3 and Volkswagen Golf R face off in Evo test

Typically when an automotive publication pits two rivals against each other, they come from different companies. After all, why would one automaker – even one parent company – develop two distinct models to compete against each other? Well, the Volkswagen Group isn't like most. It pits Porsches against Lamborghinis, Audis against Bentleys, Seats against Skodas... all under the same roof. In the high-powered hot hatch market, it offers both the VW Golf R and the Audi RS3. The question is, which is the better drive? Evo put them both on track for a quick bout of sibling rivalry to find out. On paper it would seem like an unfair fight. Sure, both are based on the same platform and channel their power to the tarmac through all four wheels. But the Audi's five-cylinder engine packs considerably more muscle than the Golf's four: 362 horsepower and 343 pound-feet of torque trump 296 hp and 280 lb-ft. There's just no way around that – at least until the Golf R 400 comes along. The Audi, as you might have guessed, also costs substantially more than the Volkswagen. But that's not Evo's concern here. This is a cost-no-object, bare-knuckle throw-down. Watch the ten-minute video above to find out if the cheaper, less powerful Golf R can keep pace with its more upscale and brawnier brother.

Audi dealer roof collapses, 20 cars crash into workshop [w/video]

The roof over a car dealership in the UK collapsed on Monday, leaving as many as 20 vehicles buried in the rubble. According to the Guardian, the incident occurred at around noon yesterday at the Audi dealership in Milton Keynes – a town of about 250,000 in Buckinghamshire that you may recognize as the home base for Red Bull Racing as well as Honda's F1 engine ship. (It's also where companies like Mercedes, Volkswagen, and Suzuki have placed their UK offices.) Workers in the service department reportedly heard a bang, then evacuated the building before the roof gave way. The section of roof that collapsed apparently serves as a multi-story parking structure at the back corner of the workshop. Firefighters responded to the scene, but fortunately no one was reported to have been injured in the incident.
