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.

Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.

VW sales increase 0.6% in September despite diesel scandal

Volkswagen was spared in the month of September from posting a sales disaster, but in reality, the impending doom and gloom is likely just postponed until October. According to VW, it delivered 26,141 vehicles to its dealerships last month, which represents a 0.6-percent gain over the same period a year ago. While up, that meager increase represents the smallest uptick of all major brands in the United States, which is currently in the middle of the best vehicular sales year in the last decade. Audi, the German automaker's mainstream luxury unit, saw a bigger gain at 16.2 percent with 17,340 total units sold, thanks in large part to the popularity of its crossover models. These numbers can't totally be taken at face value, however. In 2014, Labor Day weekend was counted as part of August's sales figures; in 2015, that traditional car-buying holiday fell early in September and is therefore partly responsible for the huge increases from all brands doing business in the United States. Remember, the diesel emissions scandal didn't hit the news until September 18, which means VW was free to sell its 2.0-liter TDI engine for the majority of the month. In other words, October is going to be the real indicator of sales reckoning as it will be the first full month that the brand can't sell its popular diesel models and the first since its emissions scandal broke. Still, TDI sales were down last month. VW reports a total of 3,060 sales of vehicles equipped with TDI engines, which represents 11.7 percent of total volume. That's nearly cut in half from the TDI's year-to-date volume percentage of 20.4 percent. "We would like to thank dealers and customers for the support of the Volkswagen brand," said Mark McNabb, chief operating officer for Volkswagen of America in a statement. "Volkswagen will continue to work diligently to regain trust and confidence in our brand." It's not yet clear exactly when VW will issue a fix to make its 2.0-liter TDI engine emissions legal, or when the EPA will recertify those models for sale. Once those two things happen, dealers will again be free to sell vehicles equipped with the powertrain, but even then it remains to be seen how consumers react when the sales ban is lifted.
