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 working on new Quattro-centric horizontal design language

If we were to opine that Audi needed a new design language, we certainly wouldn't be the first. Because while most of the vehicles wearing the Four Rings these days look slick enough, they all tend to look rather similar, and perhaps lack a certain amount of character. If the latest rumors are to be believed, Audi is working on just such a design overhaul.
The new design language being developed in the studios at Ingolstadt is said to differ from the current theme in two ways. For one, it's set to be dominated by a more horizontal approach, eschewing the tall vertical grille that dominates the noses of many of Audi's current models in favor of one that stretches more widely across the fascia.
For another, Edmunds projects that the new design language will emphasize the four-wheel-drive setup that has become Audi's hallmark. We understand that to mean more muscular wheel arches, with the rest of the design revolving around that element for an overall look that's more visually planted on the road. We'll have to wait to see how this theme develops, but the rumors at least indicate that Audi is aware of its design issues and is working to address it.

Audi boosts A3 Sportback e-tron plug-in hybrid production to 50 a day

Should we try to translate "Damn the torpedoes, full speed ahead" into German? Audi might force us to do that. That's because the German automaker has stepped up production of its new plug-in vehicle – the A3 Sportback e-tron plug-in hybrid – which is never a bad thing. Audi was circulating prototypes of the PHEV as early as 2012 and launched production this summer at a clip of 30 vehicles a day. Now, the company is saying that it's upped that daily production rate to 50. That's not exactly Ford F-150 manufacturing territory, but it's a pretty good sign that more Europeans are clamoring for the plug-in than Audi expected. The A3 E-Tron is priced at about $51,000 in Germany and pairs a 1.4-liter gas-powered engine with an electric motor to produce 204 horsepower and get the car from 0 to 60 miles per hour in less than seven and a half seconds. More impressively, the A3 Sportback e-tron plug-in hybrid can go 30 miles on electricity alone plus another 550 miles on gas power, and gets a Euro-based fuel-economy rating of a monstrous 156 miles per gallon. Check out Audi's press release below and take a look at our drive impressions here. On the line and on time: Production of the Audi A3 Sportback e-tron • First plug-in hybrid model drives off the assembly line in Ingolstadt • Assembly processes integrated into the A3 line • Maximum safety for employees, top quality for customers Production of the Audi A3 Sportback e-tron: Assembly – On the engine and component assembly line, the electric motor and transmission are fitted to the engine. Approximately 50 cars every day, with the same timing and on the same assembly line as the other models: Audi is now ramping up production of the Audi A3 Sportback e-tron*. The premium manufacturer is producing its first plug-in hybrid model at the brand's main plant in Ingolstadt. "We started series production of the Audi A3 Sportback e-tron in the summer," said Dr. Hubert Waltl, Board of Management Member for Production at AUDI AG. "Most of the assembly work is integrated into the A3 line; no separate manufacturing is necessary. That demonstrates the flexibility and efficiency of our production planners and employees." With the Audi A3 Sportback e-tron, Audi is launching the mobility of the future. The compact five-door combines a 1.4 TFSI combustion engine with a 75 kW electric motor, resulting in a total system output of 150 kW (204 horsepower).
