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.

The mood at this year’s Paris Motor Show: Quiet

The Paris Motor Show, held every other year in the early fall, typically kicks off the annual cavalcade of automotive conclaves, one that traverses the globe between autumn and spring, introducing projective, conceptual and production-ready vehicle models to the international automotive press, automotive aficionados and a public hungry for news of our increasingly futuristic mobility enterprise. But this year, at the press preview days for the show, the grounds of the Porte de Versailles convention center felt a bit more sparsely populated than usual. This was not simply a subjective sensation, or one influenced by the center's atypically dispersed assemblage of seven discrete buildings, which tends to spread out the cars and the crowds. There were not only fewer new vehicles being premiered in Paris this year, there were fewer manufacturers there to display them. Major mainstream European OEM stalwarts such as Alfa Romeo, Fiat, Nissan and Volkswagen chose to sit out Paris this year, as did boutique manufacturers like Bentley, Aston Martin and Lamborghini. This is not simply based in some antipathy on the part of the German, British and Italian manufacturers toward the French market — though for a variety of historical and societal reasons that market may be more dominated by vehicles produced domestically than others. Rather, it is part of a larger trend in the industry. Last year, Mercedes-Benz announced that it would not be participating in the flagship North American International Auto Show in 2019 — and that it might not return. Other brands including Jaguar/Land Rover, Audi, Porsche, Mazda and nearly every exotic carmaker have also departed the Detroit show. Some of these brands will still appear in the city in which the show is taking place, and host an event offsite, to capitalize on the presence of a large number of reporters in attendance. And even brands that do have a presence at the show have shifted their vehicle introductions to the days before the official press opening in an attempt to stand out from the crowd. In many ways, this makes sense. With an expanding number of automakers, with diversification and niche-ification of models and with wholesale shifts that necessitate the introduction of EV or autonomous sub-brands, there is a growing sense that, with everyone shouting at the same time, no one can be heard.

Does faster charging make you want an Audi Q7 PHEV?

Don't let the image of a heavy diesel-powered plug-in hybrid SUV fool you. The Audi Q7 E-Tron will be a quick thing when it goes on sale in Europe this summer. And the SUV will be able to be recharged at a pretty good clip as well, says Automotive News Europe. A full charge of the Q7 E-Tron can provide a range of as much as 35 miles in all-electric mode, using lenient European specifications. One of the model's bells and whistles will be battery-recharging technology that allows the SUV to be recharged at up to 7.2 kilowatts. That means that the battery can be fully recharged in about two and a half hours. Not exactly Tesla Supercharger territory, but not bad. How much a faster recharging option impacts demand for a plug-in vehicle is open to interpretation. For instance, an Idaho National Laboratory study released late last year estimated that about 85 percent of the recharging activity for the Chevrolet Volt extended-range plug-in and Nissan Leaf EV happened at home, implying that how long it takes your plug-in to fill up may not be a huge factor. So, how much would this option of faster recharging sway your decision in buying a plug-in hybrid? The Q7 E-Tron's V6 diesel engine and electric motor, which operate in a parallel hybrid setup, combine to deliver 373 horsepower and 516 pound-feet of torque. That combination can propel the SUV from 0 to 60 miles per hour in about six seconds. Of course, test that out a few times, and your all-electric range is likely to drop a bit. Audi is expanding its batch of E-Tron plug-in vehicles to better compete with German brethren BMW and Mercedes-Benz. Audi's first E-Tron, the A3, sold almost 12,000 units in Europe last year, about the same as BMW's all-electric and range-extender variants of the i3 in Europe combined, Automotive News says, citing JATO Dynamics. Audi will debut its Q5 E-Tron later this year and the A8 E-Tron in 2017. The Q7 E-Tron will be priced at about $88,000 in Europe. As for US sales of that model, questions remain about whether the SUV will have a diesel or gas-powered engine paired with the electric motor, but Americans should start getting access to it in either 2017 or 2018.
